-# Introduction
-
-Modern cars have become a lot more technologically sophisticated and different
-than those of the past. We are seeing a wider range of new features and
-functionality, with a lot more complex software. It is fair to say that the cars
-being introduced to the market today have much more in common with computing
-devices like cell phones, than their predecessors did. Modern car manufacturers
-are also integrating support for a broad range of communication technologies for
-these “connected” cars. With the advent of such vehicles, Linux has become a
-natural choice for the software platform, with Automotive Grade Linux as a
-promising example.
-
-From a security point of view, the remote capabilities of a connected car
-results in a much larger attack surface. This opens a whole new world of
-security vulnerabilities that need to be considered during the architectural
-design. History shows that physical access to a device is sufficient for a
-hacker to gain root privileges. This makes the car a hostile environment.
-
-The Security Blueprint documents the security features that are included as part
-of Automotive Grade Linux (AGL) and identifies areas that need to be addressed
-from a security perspective as part of AGL. It also gives guidance around
-existing technologies and solutions.
-
-Security domains will allow us to create a set of tests verifying the security
-of Automotive Grade Linux.
-
-This document is firstly based on an existing AGL security-blueprint.
-
-**For security to be effective, the concepts must be simple. And by default,
-anything that is not allowed is forbidden.**
-
-We will cover topics starting from the lowest level (_Hardware_) up to the
-highest levels (_Connectivity_ and _Application_). We will move quickly on
-_Hardware_ and _Connectivity_ because this is not supported at our level.
-Solutions of connectivity problems concern updates and secured settings while
-hardware securing is related to the manufacturers.
-
-The document is filled with tags to easily identify important points:
-
-<!-- section-config -->
-
-- The _config_ tag quickly identifies the configurations and the recommendations
- to take.
-
-<!-- end-section-config --><!-- section-note -->
-
-- The _note_ tag allows you to notify some additional details.
-
-<!-- end-section-note --><!-- section-todo -->
-
-- The _todo_ tag shows the possible improvements.
-
-<!-- end-section-todo -->
-
-In annexes of this document, you can find all the _config_ and _todo_ notes.
-
-## Adversaries
-
-Adversaries and attackers within the Automotive space.
-
-- Enthusiast Attackers
-
-Enthusiast attackers have physical access to the Engine Control Units (ECUs) at
-the circuit board level. They can solder ‘mod chips’ onto the board and have
-access to probing tools. They also have information on ECUs that have been
-previously compromised and have access to softwares and instructions developed
-by other members of car modification forums. The goal of the enthusiast hacker
-could be, but is not limited to, adding extra horse power to the car or hacking
-it just for fun.
-
-- Corrupt Automotive Dealers
-
-Corrupt automotive dealers are attackers that have access to the same
-capabilities as enthusiasts, but also have access to the car manufacturer’s
-(OEM) dealer network. They may also have access to standard debugging tools
-provided by the car manufacturer. Their goal may be to support local car theft
-gangs or organized criminals.
-
-- Organized Criminals
-
-Organized criminals have access to all of the above tools but may also have some
-level of control over the internal network at many dealerships. They may have
-hacked and gained temporary control of the Over-The-Air (OTA) servers or the
-In-Vehicle Infotainment (IVI) systems. This is very much like the role of
-organized criminals in other industries such as paid media today. Their goal is
-to extort money from OEMs and/or governments by threatening to disable multiple
-vehicles.
-
-- Malware Developers
-
-Malware developers have developed malicious software to attack and compromise a
-large number of vehicles. The malicious software is usually designed to spread
-from one vehicle to another. Usually, the goal is to take control of multiple
-machines and then sell access to them for malicious purposes like
-denial-of-service (DoS) attacks or theft of private information and data.
-
-- Security Researchers
-
-Security researchers are ‘self-publicized’ security consultants trying to make a
-name for themselves. They have access to standard tools for software security
-analysis. They also have physical access to the vehicle and standard hardware
-debugging tools (Logic Analyzers, Oscilloscopes, etc). Their goal is to
-publicize attacks for personal gain or just to gain personal understanding with
-a sense of helping make things more secure.
-
-## Attack Goals
-
-In today’s connected vehicle, more and more functionality is moving to software
-control, meaning that the threat of attack becomes greater and greater. We see
-car features like navigation and summoning, car access/engine start, and
-motor/ECU upgrades all controlled through software and connections to the cloud.
-The risk of attack is high because there are high value targets in play.
-
-Here, we outline some of the major threats categories along with some sample
-attackers, example attacks, and a relative importance. These threat categories
-are intended to be general examples. There can be many nuances to threat types.
-Additionally, there can be many sub-attacks that eventually lead to these higher
-level attack goals.
-
-| Threat Category | Sample Attacker | Example Attacks | Relative Importance |
-|-------------------------------|-----------------------------------------|-------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------|
-| Vehicle theft | Individual, organized criminals | Send the car to an unplanned destination, get a key for the car, gain control of the unlock mechanism | Reduced likelihood of future vehicle purchases (Profit Later), bad press (Brand Integrity) |
-| Reduced vehicle functionality | Terrorist groups, disgruntled employees | Lock the driver out of the car, cause the car to crash, block access to infotainment system | Inability sell paid-for apps and content (Profit Now), bad press (Brand Integrity), possible loss of life (Physical Injury) |
-| Vehicle hacking | Vehicle owner, competitor | Get content without paying, modify DRM licenses, unlock of after-market features, theft of IP | Loss of sales for content and features (Profit Now), lawsuits from content owners (Profit Later), loss of competitive advantage (Profit Later) |
-| Sensitive asset theft | Organized criminals, blackmailers | Steal credit card numbers, health information, camera data, steal bandwidth | Bad press (Brand Integrity), lawsuits from vehicle owners (Profit Later) |
-
-The Automotive Grade Linux (AGL) initiative builds upon open-source software
-including Linux and Tizen to offer a flexible application framework. However,
-the security provisions of the app framework, Cynara, and the security manager
-only go so far in keeping the biggest threats at bay. As experience has shown,
-providing a constrained app (like that in the Android Open Source Platform) and
-store development flow, signature verification, DAC sandboxing, and MAC (SMACK)
-controls over the platform can have a certain amount of success with the
-security of the system. However, the openness of the system invites many
-researchers, hobbyists and hackers and financially motivated attackers to
-compromise the system for their own gains.
-
-As AGL arrives on modern automobiles, this is inevitably inviting many capable
-actors to modify, attack, and compromise these well thought-out systems and
-their applications. With concerns like safety and security, the auto industry
-cannot afford to go the way of consumer devices like phones and tablets where
-security problems are encountered on a frequent basis. It is imperative to use a
-layered approach and defense-in-depth to protect the system from inevitable
-attack.
-
-## Assets and Security Categorization
-
-This section outlines some of the assets that are likely to be found in the
-vehicle and their relative sensitivity from an attack point of view.
-Additionally, the final column on the right lists some of the recommended
-protection types that can be applied to these types of assets (Note that the
-empty cells refer to the cells above them). A good protection approach will give
-priority to the most sensitive assets, using a defense-in-depth approach to
-cover these assets. Less sensitive assets are treated at a lower priority,
-typically protected with fewer protection techniques. A more fine-grained
-prioritization of the the assets in a concrete vehicle network can be achieved
-with detailed threat analysis which considers the topology of the vehicle
-network and access-controls that are in-place. e.g. the EVITA framework for
-attack trees.
-
-| Asset Category | Examples | Sensitivity | Recommended Protection Types |
-|-------------------|--------------------------------------------------------------------------------|-------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
-| Software | ECU software, infotainment software, OS images | Critical | Key Management, Mutual Asymmetric Authentication, HSM and WhiteBox Encryption, Message Integrity Checks, Hardening/SW Protection, Program Transforms/ Obfuscation, Integrity Verification, Secure OS |
-| Car Access | Biometric data, car keys | | |
-| Payment Data | Credit cards, User profile critical data | | |
-| Recordings | Internal camera recording, internal audio recording, external camera recording | High | Encryption, Message Integrity Checks, Hardening/SW Protection, Program Transforms / Obfuscation |
-| User Profile | Usernames and passwords, customization, calendar, contacts | | |
-| Location | GPS coordinates, vehicle usage data | | |
-| Purchased Content | Video, audio, licenses | | |
-| Teleconference | Chat, audio, video | Medium | SW Protection, Program Transforms / Obfuscation, Authenticated encryption for transmission |
-| Vehicle data | Vehicle info, sensor data | | |
-| Navigation data | Static and dynamic maps | | |
-| 3rd party data | Home automation commands, cloud game data | | |
-
-## Hardening term
-
-The term Hardening refers to the tools, techniques and processes required in
-order to reduce the attack surface on an embedded system, such as an embedded
-control unit (**ECU**) or other managed devices. The target for all hardening
-activities is to prevent the execution of invalid binaries on the device, and to
-prevent copying of security related data from the device.

-# Part 1 - Hardware
-
-## Abstract
-
-The Automotive Grade Linux platform is a Linux distribution with **AGL**
-compliant applications and services. The platform includes the following
-hardware:
-
-- SoC (System-on-Chip).
-- Memory (RAM, ROM, storage, etc.).
-- Peripherals.
-
-You will find in this first part everything that concerns the hardware security.
-The goal is to protect system against all attacks that are trying to gain
-additional privileges by recovering and/or changing cryptographic keys in order
-to alter the integrity of the boot. We should also prevent hardware
-modifications in order to achieve this goal. We will expose below some examples
-of possible configurations.

-Secure boot refers to preventing malicious software applications and
-“unauthorized” operating systems from loading during the system start-up
-process. The goal is to protect users from rootkits and other low-level malware
-attacks. Modern bootloaders come with features that can be used to enable secure
-boot in the system.
-
-**Boot Hardening**: Steps/requirements to configure the boot sequence, in order
-to restrict the device from executing anything other than the approved software
-image.
-
-In this part, we will see a series of settings that will allow us to improve
-security during boot phase. For the purposes of reference and explanation, we
-are providing guidance on how to configure an embedded device that runs with a
-3.10.17 Linux kernel. If the integrity is not checked or if a critical error
-occurs, the system must boot on a very stable backup image.
-
-**Requirements**: These requirements must be met even if an alternative version
-of the Linux kernel is chosen.
-
-**Recommendations**: Detailed best practices that should be applied in order to
-secure a device. Although they are not currently listed as hard requirements,
-they may be upgraded to requirements status in the future. In addition, specific
-operators may change some of these recommendations into requirements based on
-their specific needs and objectives.

-
-<!-- end-section-todo -->
-
-**Boot loader**: The boot loader consists of the Primary boot loader residing in
-**OTP** memory, sboot, U-Boot and Secure loader residing in external flash (NAND
-or SPI/NOR flash memory). The CPU on power on or reset executes the primary boot
-loader. The **OTP** primary boot loader makes the necessary initial system
-configuration and then loads the secondary boot loader sboot from external flash
-memory to ram memory. The sboot then loads the U-Boot along with the Secure
-loader. U-Boot then verifies the Kernel/system image integrity, then loads the
-Kernel/system image before passing control to it.

-# Part 4 - Kernel
-
-## Abstract
-
-**System Hardening:** Best practices associated with the configuration of an
-embedded Linux based operating system. This section includes both hardening of
-the kernel itself, as well as specific configurations and patches used to
-protect against known vulnerabilities within the build and configuration of the
-root filesystem.
-
-At the Kernel level, we must ensure that no console can be launched. It could be
-used to change the behavior of the system or to have more information about it.
-Another aspect is the protection of the memory used by the Kernel.
-
-The next sub-sections contain information on various kernel configuration
-options to enhance the security in the kernel (3.10.17) and also for
-applications compiled to take advantage of these security features.
-Additionally, there are also configuration options that protect from known
-vulnerable configuration options. Here's a high level summary of various kernel
-configurations that shall be required for deployment.
-
-## Kernel Version
-
-The choice of kernel version for the AGL system is essential to its security.
-Depending on the type of board and eventual production system, different kernel
-versions are used. For example, one of the systems under study uses the Linux
-kernel version 3.10, while another uses the Linux kernel version 4.4. For the
-Linux kernel version 3.10.31, there are 25 known vulnerabilities. These
-vulnerabilities would allow an attacker to gain privileges, bypass access
-restrictions, allow memory to be corrupted, or cause denial of service. In
-contrast, the Linux kernel version of 4.4 has many fewer known vulnerabilities.
-For this reason, we would in general recommend the later kernel version as a
-basis for the platform.
-
-Note that, although there are fewer known vulnerabilities in the most recent
-kernel versions there may be many unknown vulnerabilities underlying. A rule of
-thumb is to update the kernel as much as possible to avoid the problems you do
-know, but you should not be complacent in the trust that you place in it. A
-defense-in-depth approach would then apply.
-
-If there are constraints and dependencies in upgrading to a newer kernel version
-(e.g. device drivers, board support providers) and you are forced to an older
-Linux kernel version, there need to be additional provisions made to reduce the
-risk of kernel exploits, which can include memory monitoring, watch-dog
-services, and system call hooking. In this case, further defense-in-depth
-techniques may be required to mitigate the risk of attacks to known
-vulnerabilities, which can also include runtime integrity verification of
-components that are vulnerable to tampering.
-
-## Kernel Build Configuration
-
-The kernel build configuration is extremely important for determining the level
-of access to services and to reduce the breadth of the attack surface. Linux
-contains a great and flexible number of capabilities and this is only controlled
-through the build configuration. For example, the `CONFIG_MODULES` parameter
-allows kernel modules to be loaded at runtime extending the capabilities of the
-kernel. This capability needs to be either inhibited or controlled at runtime
-through other configuration parameters. For example, `CONFIG_MODULE_SIG_FORCE=y`
-ensures that only signed modules are loaded. There is a very large number of
-kernel configuration parameters, and these are discussed in detail in this
-section.

-# Part 5 - Platform
-
-## Abstract
-
-The Automotive Grade Linux platform is a Linux distribution with **AGL**
-compliant applications and services. The platform includes the following
-software:
-
-- Linux **BSP** configured for reference boards.
-- Proprietary device drivers for common peripherals on reference boards.
-- Application framework.
-- Windows/layer management (graphics).
-- Sound resource management.
-- An atomic software update system (chapter Update).
-- Building and debug tools (based on Yocto project).
-
-<!-- section-todo -->
-
-Domain | Improvement
-------------------- | --------------------------------
-Platform-Abstract-1 | Create a graphics and sound part.
-
-<!-- end-section-todo -->
-
-This part focuses on the AGL platform including all tools and techniques used to
-upgrade the security and downgrade the danger. It must be possible to apply the
-two fundamental principles written at the very beginning of the document. First
-of all, security management must remain simple. You must also prohibit
-everything by default, and then define a set of authorization rules. As cases to
-deal with, we must:
-
-- Implement a **MAC** for processes and files.
-- Limit communication between applications (_SystemBus_ and _SystemD_ part).
-- Prohibit all tools used during development mode (_Utilities_ and _Services_
- part).
-- Manage user capabilities (_Users_ part).
-- Manage application permissions and policies (_AGLFw_ part).
-
-<!-- section-note -->
-
-The tools and concepts used to meet these needs are only examples. Any other
-tool that meets the need can be used.
-
-<!-- end-section-note -->
-
-In AGL, as in many other embedded systems, different security mechanisms settle
-in the core layers to ensure isolation and data privacy. While the Mandatory
-Access Control layer (**SMACK**) provides global security and isolation, other
-mechanisms like **Cynara** are required to check application's permissions at
-runtime. Applicative permissions (also called "_privileges_") may vary depending
-on the user and the application being run: an application should have access to
-a given service only if it is run by the proper user and if the appropriate
-permissions are granted.
-
-## Discretionary Access Control
-
-**D**iscretionary **A**ccess **C**ontrol (**DAC**) is the traditional Linux
-method of separating users and groups from one another. In a shared environment
-where multiple users have access to a computer or network, Unix IDs have offered
-a way to contain access within privilege areas for individuals, or shared among
-the group or system. The Android system took this one step further, assigning
-new user IDs for each App. This was never the original intention of Linux UIDs,
-but was able to provide Android’s initial security element: the ability to
-sandbox applications.
-
-Although AGL mentions use of **DAC** for security isolation, the weight of the
-security responsibility lies in the **M**andatory **A**ccess **C**ontrol
-(**MAC**) and **Cynara**. Furthermore, there are system services with unique
-UIDs. however,the system does not go to the extreme of Android, where every
-application has its own UID. All sandboxing (app isolation) in AGL is handled in
-the **MAC** contexts.
-
-## Mandatory Access Control
-
-**M**andatory **A**ccess **C**ontrol (**MAC**) is an extension to **DAC**,
-whereby extended attributes (xattr) are associated with the filesystem. In the
-case of AGL, the smackfs filesystem allows files and directories to be
-associated with a SMACK label, providing the ability of further discrimination
-on access control. A SMACK label is a simple null terminated character string
-with a maximum of 255 bytes. While it doesn’t offer the richness of an SELinux
-label, which provides a user, role,type, and level, the simplicity of a single
-value makes the overall design far less complex. There is arguably less chance
-of the security author making mistakes in the policies set forth.

-# Mandatory Access Control
-
-<!-- section-note -->
-
-We decided to put the **MAC** protection on the platform part despite the fact
-that it applies to the kernel too, since its use will be mainly at the platform
-level (except floor part).
-
-<!-- end-section-note -->
-
-**M**andatory **A**ccess **C**ontrol (**MAC**) is a protection provided by the
-Linux kernel that requires a **L**inux **S**ecurity **M**odule (**LSM**). AGL
-uses an **LSM** called **S**implified **M**andatory **A**ccess **C**ontrol
-**K**ernel (**SMACK**). This protection involves the creation of **SMACK**
-labels as part of the extended attributes **SMACK** labels to the file extended
-attributes. And a policy is also created to define the behaviour of each label.
-
-The kernel access controls is based on these labels and this policy. If there is
-no rule, no access will be granted and as a consequence, what is not explicitly
-authorized is forbidden.
-
-There are two types of **SMACK** labels:
-
-- **Execution SMACK** (Attached to the process): Defines how files are
- _accessed_ and _created_ by that process.
-- **File Access SMACK** (Written to the extended attribute of the file): Defines
- _which_ process can access the file.
-
-By default a process executes with its File Access **SMACK** label unless an
-Execution **SMACK** label is defined.
-
-AGL's **SMACK** scheme is based on the _Tizen 3 Q2/2015_. It divides the System
-into the following domains:
-
-- Floor.
-- System.
-- Applications, Services and User.
-
-See [AGL security framework
-review](http://iot.bzh/download/public/2017/AMMQ1Tokyo/AGL-security-framework-review.pdf)
-and [Smack White
-Paper](http://schaufler-ca.com/yahoo_site_admin/assets/docs/SmackWhitePaper.257153003.pdf)
-for more information.
-
---------------------------------------------------------------------------------
-
-<!-- pagebreak -->
-
-## Floor
-
-The _floor_ domain includes the base system services and any associated data and
-libraries. This data remains unchanged at runtime. Writing to floor files or
-directories is allowed only in development mode or during software installation
-or upgrade.
-
-The following table details the _floor_ domain:
-
-Label | Name | Execution **SMACK** | File Access **SMACK**
------ | ----- | ------------------- | ---------------------------------------
-`-` | Floor | `r-x` for all | Only kernel and internal kernel thread.
-`^` | Hat | `---` for all | `rx` on all domains.
-`*` | Star | `rwx` for all | None
-
-<!-- section-note -->
-
-- The Hat label is Only for privileged system services (currently only
- systemd-journal). Useful for backup or virus scans. No file with this label
- should exist except in the debug log.
-
-- The Star label is used for device files or `/tmp` Access restriction managed
- via **DAC**. Individual files remain protected by their **SMACK** label.
-
-<!-- end-section-note --> <!-- section-config -->
-
-Domain | `Label` name | Recommendations
------------------- | ------------ | -----------------------------------------------------------
-Kernel-MAC-Floor-1 | `^` | Only for privileged system services.
-Kernel-MAC-Floor-2 | `*` | Used for device files or `/tmp` Access restriction via DAC.
-
-<!-- end-section-config -->
-
---------------------------------------------------------------------------------
-
-<!-- pagebreak -->
-
-## System
-
-The _system_ domain includes a reduced set of core system services of the OS and
-any associated data. This data may change at runtime.
-
-The following table details the _system_ domain:
-
-Label | Name | Execution **SMACK** | File Access **SMACK**
----------------- | --------- | ----------------------------------------------- | ---------------------
-`System` | System | None | Privileged processes
-`System::Run` | Run | `rwxatl` for User and System label | None
-`System::Shared` | Shared | `rwxatl` for system domain `r-x` for User label | None
-`System::Log` | Log | `rwa` for System label `xa` for user label | None
-`System::Sub` | SubSystem | Subsystem Config files | SubSystem only
-
-<!-- section-config -->
-
-Domain | `Label` name | Recommendations
-------------------- | ---------------- | -------------------------------------------------------------------------------------------------------------
-Kernel-MAC-System-1 | `System` | Process should write only to file with transmute attribute.
-Kernel-MAC-System-2 | `System::run` | Files are created with the directory label from user and system domain (transmute) Lock is implicit with `w`.
-Kernel-MAC-System-3 | `System::Shared` | Files are created with the directory label from system domain (transmute) User domain has locked privilege.
-Kernel-MAC-System-4 | `System::Log` | Some limitation may impose to add `w` to enable append.
-Kernel-MAC-System-5 | `System::Sub` | Isolation of risky Subsystem.
-
-<!-- end-section-config -->
-
---------------------------------------------------------------------------------
-
-<!-- pagebreak -->
-
-## Applications, Services and User
-
-The _application_, _services_ and _user_ domain includes code that provides
-services to the system and user, as well as any associated data. All code
-running on this domain is under _Cynara_ control.
-
-The following table details the _application_, _services_ and _user_ domain:
-
-Label | Name | Execution **SMACK** | File Access **SMACK**
-------------------- | ------ | --------------------------------------------------------------------------- | ---------------------------
-`User::Pkg::$AppID` | AppID | `rwx` (for files created by the App). `rx` for files installed by **AppFw** | $App runtime executing $App
-`User::Home` | Home | `rwx-t` from System label `r-x-l` from App | None
-`User::App-Shared` | Shared | `rwxat` from System and User domains label of $User | None
-
-<!-- section-config -->
-
-Domain | `Label` name | Recommendations
-------------------- | ------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------
-Kernel-MAC-System-1 | `User::Pkg::$AppID` | Only one Label is allowed per App. A data directory is created by the AppFw in `rwx` mode.
-Kernel-MAC-System-2 | `User::Home` | AppFw needs to create a directory in `/home/$USER/App-Shared` at first launch if not present with label app-data access is `User::App-Shared` without transmute.
-Kernel-MAC-System-3 | `User::App-Shared` | Shared space between all App running for a given user.
-
-<!-- end-section-config -->
-
-## Attack Vectors
-
-There are 4 major components to the system:
-
-- The LSM kernel module.
-- The `smackfs` filesystem.
-- Basic utilities for policy management and checking.
-- The policy/configuration data.
-
-As with any mandatory access system, the policy management needs to be carefully
-separated from the checking, as the management utilities can become a convenient
-point of attack. Dynamic additions to the policy system need to be carefully
-verified, as the ability to update the policies is often needed, but introduces
-a possible threat. Finally, even if the policy management is well secured, the
-policy checking and failure response to that checking is also of vital
-importance to the smooth operation of the system.
-
-While **MAC** is a certainly a step up in security when compared to DAC, there
-are still many ways to compromise a SMACK-enabled Linux system. Some of these
-ways are as follows:
-
-- Disabling SMACK at invocation of the kernel (with command-line:
- security=none).
-- Disabling SMACK in the kernel build and redeploying the kernel.
-- Changing a SMACK attribute of a file or directory at install time.
-- Tampering with a process with the CAP_MAC_ADMIN privilege.
-- Setting/Re-setting the SMACK label of a file.
-- Tampering with the default domains (i.e.
- /etc/smack/accesses.d/default-access-domains).
-- Disabling or tampering with the SMACK filesystem (i.e. /smackfs).
-- Adding policies with `smackload` (adding the utility if not present).
-- Changing labels with `chsmack` (adding the utility if not present).

-
-`afm-system-daemon` is used to:
-
-- Manage users and user sessions.
-- Setup applications and services (_CGroups_, _namespaces_, autostart, permissions).
-- Use of `libsystemd` for its programs (event management, **D-Bus** interface).

-## Benefits
-
-- Removal of one privileged process: **afm-user-daemon**
-- Access and use of high level features:
-
- - Socket activation.
- - Management of users and integration of **PAM**.
- - Dependency resolution to services.
- - `Cgroups` and resource control.
- - `Namespaces` containerization.
- - Autostart of required API.
- - Permissions and security settings.
- - Network management.
-
-<!-- pagebreak -->
-
-## CGroups
-
-Control Groups offer a lot of features, with the most useful ones you can
-control: Memory usage, how much CPU time is allocated, how much device I/O is
-allowed or which devices can be accessed. **SystemD** uses _CGroups_ to organise
-processes (each service is a _CGroups_, and all processes started by that
-service use that _CGroups_). By default, **SystemD** automatically creates a
-hierarchy of slice, scope and service units to provide a unified structure for
-the _CGroups_ tree. With the `systemctl` command, you can further modify this
-structure by creating custom slices. Currently, in AGL, there are 2 slices
-(**user.slice** and **system.slice**).
-
-## Namespaces
-
-### User side
-
-There are several ways of authenticating users (Key Radio Frequency, Phone,
-Gesture, ...). Each authentication provides dynamic allocation of **uids** to
-authenticated users. **Uids** is used to ensure privacy of users and **SMACK**
-for applications privacy.
-
-First, the user initiates authentication with **PAM** activation. **PAM**
-Standard offers highly configurable authentication with modular design like
-face recognition, Voice identification or with a password. Then users should
-access identity services with services and applications.

-# D-Bus
-
-D-Bus is a well-known **IPC** (Inter-Process Communication) protocol (and

-because it allows to implement discovery and signaling.
-
-The D-Bus session is by default addressed by environment variable
-`DBUS_SESSION_BUS_ADDRESS`. Using **systemd** variable
-`DBUS_SESSION_BUS_ADDRESS` is automatically set for user sessions. D-Bus usage
-is linked to permissions.
-
-D-Bus has already had several [security
-issues](https://www.cvedetails.com/vulnerability-list/vendor_id-13442/D-bus-Project.html)

-
-# Application framework/model (**AppFw**)
-
-The AGL application framework consists of several inter-working parts:
-
-- **SMACK**: The kernel level **LSM** (**L**inux **S**ecurity **M**odule) that
- performs extended access control of the system.
-- **Cynara**: the native gatekeeper daemon used for policy handling, updating to
- the database and policy checking.
-- Security Manager: a master service, through which all security events are
- intended to take place.
-- Several native application framework utilities: `afm-main-binding`,
- `afm-user-daemon`, `afm-system-daemon`.
-
-The application framework manages:
-
-- The applications and services management: Installing, Uninstalling, Listing,
- ...
-- The life cycle of applications: Start -> (Pause, Resume) -> Stop.
-- Events and signals propagation.
-- Privileges granting and checking.
-- API for interaction with applications.
-
-<!-- section-note -->
-
-- The **security model** refers to the security model used to ensure security
- and to the tools that are provided for implementing that model. It's an
- implementation detail that should not impact the layers above the application
- framework.
-
-- The **security model** refers to how **DAC** (**D**iscretionary **A**ccess
- **C**ontrol), **MAC** (Mandatory Access Control) and `Capabilities` are used
- by the system to ensure security and privacy. It also includes features of
- reporting using audit features and by managing logs and alerts.
-
-<!-- end-section-note -->
-
-The **AppFw** uses the security model to ensure the security and the privacy of
-the applications that it manages. It must be compliant with the underlying
-security model. But it should hide it to the applications.

-
-The Security Manager communicates policy information to **Cynara**, which
-retains information in its own database in the format of a text file with
-comma-separated values (CSV). There are provisions to retain a copy of the CSV
-text file when the file is being updated.
-
-Runtime checking occurs through **Cynara**. Each application that is added to
-the framework has its own instantiation of a SMACK context and D-bus bindings.
-The afb_daemon and Binder form a web-service that is communicated to through
-http or a websocket from the application-proper. This http or websocket
-interface uses a standard unique web token for API communication.
-
-![Application Framework Flow](App-flow.png)
-
-## Cynara
-
-There's a need for another mechanism responsible for checking applicative
-permissions: Currently in AGL, this task depends on a policy-checker service
-(**Cynara**).
-
-- Stores complex policies in databases.
-- "Soft" security (access is checked by the framework).
-
-Cynara interact with **D-Bus** in order to deliver this information.
-
-Cynara consists of several parts:
-
-- Cynara: a daemon for controlling policies and responding to access control
- requests.
-- Database: a spot to hold policies.
-- Libraries: several static and dynamic libraries for communicating with Cynara.
-
-The daemon communicates to the libraries over Unix domain sockets. The database
-storage format is a series of CSV-like files with an index file.
-
-There are several ways that an attacker can manipulate policies of the Cynara
-system:
-
-- Disable Cynara by killing the process.
-- Tamper with the Cynara binary on-disk or in-memory.
-- Corrupt the database controlled by Cynara.
-- Tamper with the database controlled by Cynara.
-- Highjack the communication between Cynara and the database.
-
-The text-based database is the weakest part of the system and although there are
-some consistency mechanisms in place (i.e. the backup guard), these mechanisms
-are weak at best and can be countered by an attacker very easily.

-### Policies
-
-- Policy rules:
-
- - Are simple - for pair [application context, privilege] there is straight
- answer (single Policy Type): [ALLOW / DENY / ...].
- - No code is executed (no script).
- - Can be easily cached and managed.
-
-- Application context (describes id of the user and the application credentials)
- It is build of:
-
- - UID of the user that runs the application.
- - **SMACK** label of application.
-
-## Holding policies
-
-Policies are kept in buckets. Buckets are set of policies which have additional
-a property of default answer, the default answer is yielded if no policy matches
-searched key. Buckets have names which might be used in policies (for
-directions).

-The following attack vectors are not completely independent. While attackers may
-have varying levels of access to an AGL system, experience has shown that a
-typical attack can start with direct access to a system, find the
-vulnerabilities, then proceed to automate the attack such that it can be invoked
-from less accessible standpoint (e.g. remotely). Therefore, it is important to
-assess all threat levels, and protect the system appropriately understanding
-that direct access attacks are the door-way into remote attacks.
-
-### Remote Attacks
-
-The local web server interface used for applications is the first point of
-attack, as web service APIs are well understood and easily intercepted. The
-local web server could potentially be exploited by redirecting web requests
-through the local service and exploiting the APIs. While there is the use of a
-security token on the web service API, this is weak textual matching at best.
-This will not be difficult to spoof. It is well known that [API Keys do not
-provide any real security](http://nordicapis.com/why-api-keys-are-not-enough/).
-
-It is likely that the architectural inclusion of an http / web-service interface
-provided the most flexibility for applications to be written natively or in
-HTML5. However, this flexibility may trade-off with security concerns. For
-example, if a native application were linked directly to the underlying
-framework services, there would be fewer concerns over remote attacks coming
-through the web-service interface.
-
-Leaving the interface as designed, mitigations to attacks could include further
-securing the interface layer with cryptographic protocols: e.g. encrypted
-information passing, key exchange (e.g. Elliptic-Curve Diffie-Hellman).
-
-### User-level Native Attacks
-
-- Modifying the CSV data-base
-- Modifying the SQLite DB
-- Tampering with the user-level binaries
-- Tampering with the user daemons
-- Spoofing the D-bus Interface
-- Adding executables/libraries
-
-With direct access to the device, there are many security concerns on the native
-level. For example, as **Cynara** uses a text file data-base with
-comma-separated values (CSV), an attacker could simply modify the data-base to
-escalate privileges of an application. Once a single application has all the
-privileges possible on the system, exploits can come through in this manner.
-Similarly the SQLite database used by the Security Manager is not much different
-than a simple text file. There are many tools available to add, remove, modify
-entries in an SQLite data-base.
-
-On the next level, a common point of attack is to modify binaries or daemons for
-exploiting functionality. There are many Linux tools available to aid in this
-regard, including: [IDA Pro](https://www.hex-rays.com/products/ida/index.shtml),
-and [radare2](https://rada.re/r/). With the ability to modify binaries, an
-attacker can do any number of activities including: removing calls to security
-checks, redirecting control to bypass verification functionality, ignoring
-security policy handling, escalating privileges, etc.
-
-Additionally, another attack vector would be to spoof the D-bus interface. D-bus
-is a message passing system built upon Inter-Process Communication (IPC), where
-structured messages are passed based upon a protocol. The interface is generic
-and well documented. Therefore, modifying or adding binaries/libraries to spoof
-this interface is a relatively straight-forward process. Once the interface has
-been spoofed, the attacker can issue any number of commands that lead into
-control of low-level functionality.
-
-Protecting a system from native attacks requires a methodical approach. First,
-the system should reject processes that are not sanctioned to run.
-Signature-level verification at installation time will help in this regard, but
-run-time integrity verification is much better. Signatures need to originate
-from authorized parties, which is discussed further in a later section on the
-Application Store.
-
-On the next level, executables should not be allowed to do things where they
-have not been granted permission. DAC and SMACK policies can help in this
-regard. On the other hand, there remain concerns with memory accesses, system
-calls, and other process activity that may go undetected. For this reason, a
-secure environment which monitors all activity can give indication of all
-unauthorized activity on the system.
-
-Finally, it is very difficult to catch attacks of direct tampering in a system.
-These types of attacks require a defense-in-depth approach, where complementary
-software protection and hardening techniques are needed. Tamper-resistance and
-anti-reverse-engineering technologies include program
-transformations/obfuscation, integrity verification, and white-box cryptography.
-If applied in a mutually-dependent fashion and considering performance/security
-tradeoffs, the approach can provide an effective barrier to direct attacks to
-the system. Furthermore, the use of threat monitoring provides a valuable
-telemetry/analytics capability and the ability to react and renew a system under
-attack.
-
-### Root-level Native Attacks
-
-- Tampering the system daemon
-- Tampering Cynara
-- Tampering the security manager
-- Disabling SMACK
-- Tampering the kernel
-
-Once root-level access (i.e. su) has been achieved on the device, there are many
-ways to compromise the system. The system daemon, **Cynara**, and the security
-manager are vulnerable to tampering attacks. For example, an executable can be
-modified in memory to jam a branch, jump to an address, or disregard a check.
-This can be as simple as replacing a branch instruction with a NOP, changing a
-memory value, or using a debugger (e.g. gdb, IDA) to change an instruction.
-Tampering these executables would mean that policies can be ignored and
-verification checks can be bypassed.
-
-Without going so far as to tamper an executable, the **SMACK** system is also
-vulnerable to attack. For example, if the kernel is stopped and restarted with
-the *security=none* flag, then SMACK is not enabled. Furthermore, `systemd`
-starts the loading of **SMACK** rules during start-up. If this start-up process
-is interfered with, then **SMACK** will not run. Alternatively, new policies can
-be added with `smackload` allowing unforseen privileges to alternative
-applications/executables.
-
-Another intrusion on the kernel level is to rebuild the kernel (as it is
-open-source) and replace it with a copy that has **SMACK** disabled, or even
-just the **SMACK** filesystem (`smackfs`) disabled. Without the extended label
-attributes, the **SMACK** system is disabled.
-
-Root-level access to the device has ultimate power, where the entire system can
-be compromised. More so, a system with this level access allows an attacker to
-craft a simpler *point-attack* which can operate on a level requiring fewer
-privileges (e.g. remote access, user-level access).
-
-## Vulnerable Resources
-
-### Resource: `afm-user-daemon`
-
-The `afm-user-daemon` is in charge of handling applications on behalf of a user.
-Its main tasks are:
-
-- Enumerate applications that the end user can run and keep this list available
- on demand.
-- Start applications on behalf of the end user, set user running environment,
- set user security context.
-- List current runnable or running applications.
-- Stop (aka pause), continue (aka resume), terminate a running instance of a
- given application.
-- Transfer requests for installation/uninstallation of applications to the
- corresponding system daemon afm-system-daemon.
-
-The `afm-user-daemon` launches applications. It builds a secure environment for
-the application before starting it within that environment. Different kinds of
-applications can be launched, based on a configuration file that describes how
-to launch an application of a given kind within a given launching mode: local or
-remote. Launching an application locally means that the application and its
-binder are launched together. Launching an application remotely translates in
-only launching the application binder.
-
-The UI by itself has to be activated remotely by a request (i.e. HTML5
-homescreen in a browser). Once launched, running instances of the application
-receive a `runid` that identifies them. `afm-user-daemon` manages the list of
-applications that it has launched. When owning the right permissions, a client
-can get the list of running instances and details about a specific running
-instance. It can also terminate, stop or continue a given application. If the
-client owns the right permissions, `afm-user-daemon` delegates the task of
-installing and uninstalling applications to `afm-system-daemon`.
-
-`afm-user-daemon` is launched as a `systemd` service attached to a user session.
-Normally, the service file is located at
-/usr/lib/systemd/user/afm-user-daemon.service.
-
-Attacker goals:
-
-- Disable `afm-user-daemon`.
-- Tamper with the `afm-user-daemon` configuration.
- - /usr/lib/systemd/user/afm-user-daemon.service.
- - Application(widget) config.xml file.
- - /etc/afm/afm-launch.conf (launcher configuration).
-
-- Escalate user privileges to gain more access with `afm-user-daemon`.
-- Install malicious application (widget).
-- Tamper with `afm-user-daemon` on disk or in memory.
-
-### Resource: `afm-system-daemon`
-
-The `afm-system-daemon` is in charge of installing applications on the AGL
-system. Its main tasks are:
-
-- Install applications and setup security framework for newly installed
- applications.
-- Uninstall applications.
-
-`afm-system-daemon` is launched as a `systemd` service attached to system.
-Normally, the service file is located at
-/lib/systemd/system/afm-systemdaemon.service.
-
-Attacker goals:
-
-- Disable `afm-system-daemon`.
-- Tamper with the `afm-system-daemon` configuration.
-- Tamper `afm-system-daemon` on disk or in memory.
-
-### Resource `afb-daemon`
-
-`afb-binder` is in charge of serving resources and features through an HTTP
-interface. `afb-daemon` is in charge of binding one instance of an application
-to the AGL framework and AGL system. The application and its companion binder
-run in a secured and isolated environment set for them. Applications are
-intended to access to AGL system through the binder. `afb-daemon` binders serve
-files through HTTP protocol and offers developers the capability to expose
-application API methods through HTTP or WebSocket protocol.
-
-Binder bindings are used to add APIs to `afb-daemon`. The user can write a
-binding for `afb-daemon`. The binder `afb-daemon` serves multiple purposes:
-
-1. It acts as a gateway for the application to access the system.
-2. It acts as an HTTP server for serving files to HTML5 applications.
-3. It allows HTML5 applications to have native extensions subject to security
- enforcement for accessing hardware resources or for speeding up parts of
- algorithm.
-
-Attacker goals:
-
-- Break from isolation.
-- Disable `afb-daemon`.
-- Tamper `afb-demon` on disk or in memory.
-- Tamper **capabilities** by creating/installing custom bindings for
- `afb-daemon`. \ No newline at end of file

-

-title: Introduction
----
-
-# Part 6 - Application
-
-## Abstract
-
-**Application Hardening**: Best practices to apply to the build and release of
-user space applications, in order to reduce the number of attack surfaces used
-by potential attackers.
-
-The term of Application (App) has a very wide definition in **AGL**. Almost
-anything which is not in the core Operating System (OS) is an Application.
-Applications can be included in the base software package (image) or can be
-added at run-time.
-
-Application containment is achieved using the following protections:
-
-- Linux Native protection
- - Mandatory Access Control (**MAC**)
-- AGL Platform protections
- - Origin Tracking and Validation
- - Application Privilege Management and Enforcement via Cynara
- - Authenticated Transport via D-Bus
-
-## Application Types
-
-AGL provides a framework for applications to be written in different forms:
-
-- Web application: HTML5 + JavaScript
-- Qt application: in a QML file
-- Native application: in C
-
-While there is no harm in providing multiple types of applications, from a
-security perspective this does increase the attack surface for an intruder. The
-application framework (**AppFw**) consists of a number of utilities and daemons
-which provide context for the applications. Isolation is provided through
-**SMACK** labels.
-
-## Application Store
-
-Although the Tizen system has defined a [system of App signing and signing
-flow](https://wiki.tizen.org/Security/Tizen_3.X_Overview#Application_Singing_and_Certificates)
-to avoid the spread of unauthorized Apps that might contain malware. At this
-point, it is unclear how much of this flow AGL will adopt. However, judging from
-the experience, it is an essential topic. For example, the Google Play Store
-controls the authorization of Apps through signing, and still, there are [many
-accounts of Apps containing malware on the
-store](http://www.eweek.com/mobile/researchers-find-132-malware-infected-android-apps-on-google-play).
-
-Tizen defines 5 levels of certificates and signing at each level, including an
-author, testing distributor, public level store distributor, partner level store
-distributor, and platform level store distributor. AGL may define a different
-number of third parties, but at a minimum an author and store distributor should
-be defined.
-
-![App Signing Flow](App_signing_flow.png)
-
-Once the number of signatures has been established, verification of those
-signatures needs to be done at a minimum at installation time on the AGL device.
-It is important to ensure the robustness/integrity of the public key used for
-signature verification. If the public key is modified, then this compromised key
-can be used to verify an attacker's private key signature.
-
-Further to this, installation-time verification is limited. Attacks can happen
-to apps in-memory at runtime. Any modifications made after installation will be
-missed by installation-time verification. Integrity verification that runs
-during execution makes for a more complete security story.

-# Bus
-
-We only speak about the **CAN** bus to take an example, because the different
-attacks on bus like _FlewRay_, _ByteFlight_, _Most_ and _Lin_ use retro
-engineering and the main argument to improve their security is to encrypt data
-packets. We just describe them a bit:
-
-- **CAN**: Controller Area Network, developed in the early 1980s, is an
- event-triggered controller network for serial communication with data rates up
- to one MBit/s. **CAN** messages are classified over their respective
- identifier. **CAN** controller broadcast their messages to all connected nodes
- and all receiving nodes decide independently if they process the message.
-- **FlewRay**: Is a deterministic and error-tolerant high-speed bus. With a data
- rate up to 10 MBit/s.
-- **ByteFlight**: Is used for safety-critical applications in motor vehicles
- like air-bags. Byteflight runs at 10Mbps over 2 or 3 wires plastic optical
- fibers.
-- **Most**: Media Oriented System Transport, is used for transmitting audio,
- video, voice, and control data via fiber optic cables. The speed is, for the
- synchronous way, up to 24 MBit/s and asynchronous way up to 14 MBit/s.
- **MOST** messages include always a clear sender and receiver address.
-- **LIN**: Local Interconnect Network, is a single-wire subnet work for
- low-cost, serial communication between smart sensors and actuators with
- typical data rates up to 20 kBit/s. It is intended to be used from the year
- 2001 on everywhere in a car, where the bandwidth and versatility of a **CAN**
- network is not required.
-
-On just about every vehicle, **ECU**s (**E**lectronic **C**ontrol **U**nits)
-communicate over a CAN bus, which is a two-wire bus using hardware arbitration
-for messages sent on the shared medium. This is essentially a *trusted* network
-where all traffic is visible to all controllers and any controller can send any
-message.
-
-A malicious **ECU** on the CAN bus can easily inject messages destined for any
-other device, including things like the instrument cluster and the head unit.
-There are common ways for hardware to do USB to CAN and open source software to
-send and receive messages. For example, there is a driver included in the Linux
-kernel that can be used to send/receive CAN signals. A malicious device on the
-CAN bus can cause a great number of harmful things to happen to the system,
-including: sending bogus information to other devices, sending unintended
-commands to ECUs, causing DOS (Denial Of Service) on the CAN bus, etc.

-for more information.
-
-# Connectors
-
-For the connectors, we supposed that they were disabled by default. For example,
-the **USB** must be disabled to avoid attacks like BadUSB. If not, configure the
-Kernel to only enable the minimum require **USB** devices. The connectors used
-to diagnose the car like **OBD-II** must be disabled outside garages.

-## Wifi
-
-### Attacks
-
-We can differentiate existing attacks on wifi in two categories: Those on
-**WEP** and those on **WPA**.
-
-- **WEP** attacks:
-
- - **FMS**: (**F**luhrer, **M**antin and **S**hamir attack) is a "Stream cipher
- attack on the widely used RC4 stream cipher. The attack allows an attacker
- to recover the key in an RC4 encrypted stream from a large number of
- messages in that stream."
- - **KoreK**: "Allows the attacker to reduce the key space".
- - **PTW**: (**P**yshkin **T**ews **W**einmann attack).
- - **Chopchop**: Found by KoreK, "Weakness of the CRC32 checksum and the lack
- of replay protection."
- - **Fragmentation**
-
-- **WPA** attacks:
-
- - **Beck and Tews**: Exploit weakness in **TKIP**. "Allow the attacker to
- decrypt **ARP** packets and to inject traffic into a network, even allowing
- him to perform a **DoS** or an **ARP** poisoning".
- - [KRACK](https://github.com/kristate/krackinfo): (K)ey (R)einstallation
- (A)tta(ck) ([jira AGL
- SPEC-1017](https://jira.automotivelinux.org/browse/SPEC-1017)).
-
-### Recommendations
-
-- Do not use **WEP**, **PSK** and **TKIP**.
-
-- Use **WPA2** with **CCMP**.
-
-- Should protect data sniffing.

-
-## Bluetooth
-
-### Attacks
-
-- **Bluesnarfing** attacks involve an attacker covertly gaining access to your
- Bluetooth-enabled device for the purpose of retrieving information, including
- addresses, calendar information or even the device's **I**nternational
- **M**obile **E**quipment **I**dentity. With the **IMEI**, an attacker could
- route your incoming calls to his cell phone.
-- **Bluebugging** is a form of Bluetooth attack often caused by a lack of
- awareness. Similar to bluesnarfing, bluebugging accesses and uses all phone
- features but is limited by the transmitting power of class 2 Bluetooth radios,
- normally capping its range at 10-15 meters.
-- **Bluejacking** is the sending of unsolicited messages.
-- **BLE**: **B**luetooth **L**ow **E**nergy
- [attacks](https://www.usenix.org/system/files/conference/woot13/woot13-ryan.pdf).
-- **DoS**: Drain a device's battery or temporarily paralyze the phone.
-
-### Recommendations
-
-- Not allowing Bluetooth pairing attempts without the driver's first manually
- placing the vehicle in pairing mode.
-- Monitoring.
-- Use **BLE** with caution.
-- For v2.1 and later devices using **S**ecure **S**imple **P**airing (**SSP**),
- avoid using the "Just Works" association model. The device must verify that an
- authenticated link key was generated during pairing.

-## Transport
-
-For data transport, it is necessary to **encrypt data end-to-end**. To prevent
-**MITM** attacks, no third party should be able to interpret transported data.
-Another aspect is the data anonymization in order to protect the leakage of
-private information on the user or any other third party.
-
-The use of standards such as **IPSec** provides "_private and secure
-communications over IP networks, through the use of cryptographic security
-services, is a set of protocols using algorithms to transport secure data over
-an IP network._". In addition, **IPSec** operates at the network layer of the
-**OSI** model, contrary to previous standards that operate at the application
-layer. This makes its application independent and means that users do not need
-to configure each application to **IPSec** standards.
-
-**IPSec** provides the services below :
-
-- Confidentiality: A service that makes it impossible to interpret data if it is
- not the recipient. It is the encryption function that provides this service by
- transforming intelligible (unencrypted) data into unintelligible (encrypted)
- data.
-- Authentication: A service that ensures that a piece of data comes from where
- it is supposed to come from.
-- Integrity: A service that consists in ensuring that data has not been tampered
- with accidentally or fraudulently.
-- Replay Protection: A service that prevents attacks by re-sending a valid
- intercepted packet to the network for the same authorization. This service is
- provided by the presence of a sequence number.
-- Key management: Mechanism for negotiating the length of encryption keys
- between two **IPSec** elements and exchange of these keys.
-
-An additional means of protection would be to do the monitoring between users
-and the cloud as a **CASB** will provide.

-# Part 8 - Update (**OTA**)
-
-## Abstract
-
-Updating applications and firmware is essential for the development of new
-features and even more to fix security bugs. However, if a malicious third party
-manages to alter the content during transport, it could alter the functioning of
-the system and/or applications. The security of the updates is therefore a
-critical point to evaluate in order to guarantee the integrity, the
-confidentiality and the legitimacy of the transmitted data.
-
-## Attack Vectors
-
-Updates Over The Air are one of the most common points where an attacker will
-penetrate. An OTA update mechanism is one of the highest threats in the system.
-If an attacker is able to install his own application or firmware on the system,
-he can get the same level of access that the original application or firmware
-had. From that point, the intruder can get unfettered access to the rest of the
-system, which might include making modifications, downloading other pieces of
-software, and stealing assets.
-
-### Man In The Middle (MITM)
-
-The man-in-the-middle attack is the most classic example of an attack, where an
-adversary inserts himself between two communicating entities and grabs whatever
-is being communicated. In the case of OTA attacks, the connection in the network
-may be intercepted:
-
-* On the internet, before the cloud back-end.
-* At the base station, 3G,4G,5G connection to the internet.
-* At the receiving antenna, connection to the car.
-* Between the receiving antenna and the gateway router (if present), connection
- within the car.
-* Between the gateway router and the target component (IVI, In-Vehicle
- Infotainment unit).
-
-There are many ways to mount a MITM attack. For example, proxy tools like Burp
-Proxy can be used to intercept web traffic as a man-in-the-middle. Under the
-guise of being a testing tool, the proxy server is often used in attack
-scenarios. It runs on a variety of platforms.
-
-As another example, false base station attacks are known to be fairly easy to
-set-up. The problem is apparently fairly prevalent in countries like China and
-in the UK. These fake base stations are sometimes just eavesdropping on the
-communication, but others have the potential to do serious harm.
-
-Defenses against MITM attacks include encrypted and signed data pipes.
-Furthermore, architects and developers are also recommended to encrypt and sign
-the payloads that are being passed over these pipes, to defend against perusal
-of the data.
-
-### Man At The End (MATE)
-
-The man-at-the-end attack is when an intruder analyzes the end-point of the
-communication when software is accessing the data communication. This is a more
-severe attack type where the attacker can:
-
-* Steal keys.
- * For example, a simple debugging session in running software could reveal a
- key used in memory.
-* Tamper software.
- * For example, replacing just one function call in software with a NOP (i.e.
- no operation) can drastically change the behavior of the program.
-* Jam branches of control.
- * For example, making a program take one branch of control rather than the
- intended branch can mean the difference between an authorized and a
- non-authorized installation.
-* Modify important data.
- * For example, if the data changed is a key or data leading to a control path,
- then this attack can be severe.
- * In the case of OTA updates, MATE attacks are particularly problematic for

-# Firmware Over The Air
-
-The firmware update is critical since its alteration back to compromise the
-entire system. It is therefore necessary to take appropriate protective
-measures.
-
-AGL includes the _meta-updater_ Yocto layer that enables OTA software updates
-via [Uptane](https://uptane.github.io), an automotive-specific extension to [The
-Update Framework](https://theupdateframework.github.io/). Uptane and TUF are
-open standards that define a secure protocol for delivering and verifying
-updates even when the servers and network--internet and car-internal--aren't
-fully trusted.
-
-_meta-updater_ includes the application
-[`aktualizr`](https://github.com/advancedtelematic/aktualizr), developed
-Advanced Telematic Systems (now part of HERE Technologies) that enables OTA for
-an ECU. `aktualizr` combined with Uptane is suitable for updating the firmware,
-software, and other packages on even functionally critical ECUs. `aktualizr` can
-be enabled with the free, open souce backend
-[`ota-community-edition`](https://github.com/advancedtelematic/ota-community-edition).
-
-This FOTA update mechanism can be enabled through the `agl-sota` feature.
-
-## Building
-
-To build an AGL image that uses `aktualizr`, the following can be used.
-
-```
-source meta-agl/scripts/aglsetup.sh -m <machine> agl-sota <other-features...>
-```
-
-During the build, _meta-updater_ will use credentials downloaded from
-`ota-community-edition` to sign metadata verifying the build as authentic. These
-signatures are part of the Uptane framework and are used to verify FOTA updates.
-
-## Atomic Upgrades with Rollbacks
-
-`aktualizr`'s primary method of updating firmware is to use `libostree` with
-binary diffs. The binary diffs use the least amout of bandwidth, and by it's
-nature `libostree` stores current and previous firmware versions on disk or in
-flash memory to allow for rollbacks.
-
-`libostree` is a content addressable object store much like `git`. Versions are
-specified via SHA2-256. These hashes are signed in the Uptane metadata and are
-robust against cryptographic compromise.

-# Software Over The Air
-
-Software updates in connected vehicles are a very useful feature, which can
-deliver significant benefits. If not implemented with security in mind, software
-updates can incur serious vulnerabilities. Any software update system must
-ensure that not only are the software updates to devices done in a secure way,
-but also that the repositories and servers hosting these updates are adequately
-protected. As the process of updating software migrates from a Dealership update
-model towards an **OTA** update model, securing these processes becomes a high
-priority.
-
-**SOTA** is made possible by **AppFw** (See Platform part). It will be possible
-to manage in a simple way the packets (i.g. Android like).
