Shutting out intruders with AppArmor

PROTECTIVE ARMOR

Author(s): RALF SPENNEBERG

Whereas SE Linux is comparatively difficult to configure, but implements comprehensive MACs (Mandatory Access Control), AppArmor focuses on restricting the scope of individual applications. The Task It is an unfortunate fact that many programs suffer from bugs, and web applications are particularly badly hit.
