# The security framework

NOT STARTED !!!!!!

## Setting Smack rules for the application

For Tizen, the following rules are set by the security manager for each application.

    System ~APP~             rwx
    System ~PKG~             rwxat
    System ~PKG~::RO         rwxat
    ~APP~  System            wx
    ~APP~  System::Shared    rxl
    ~APP~  System::Run       rwxat
    ~APP~  System::Log       rwxa
    ~APP~  _                 l
    User   ~APP~             rwx
    User   ~PKG~             rwxat
    User   ~PKG~::RO         rwxat
    ~APP~  User              wx
    ~APP~  User::Home        rxl
    ~APP~  User::App::Shared rwxat
    ~APP~  ~PKG~             rwxat
    ~APP~  ~PKG~::RO         rxl

Here, ~PKG~ is the identifier of the package and ~APP~ is the identifier of the application.
