AppArmor

AppArmor ("Application Armor") is a Linux kernelsecurity module that allows system administrators to restrict programs' capabilities with per-program profiles. Profiles can allow capabilities like network access, raw socket access, and the permission to read, write, or execute files on matching paths. AppArmor supplements the traditional Unixdiscretionary access control (DAC) model by providing mandatory access control (MAC). It has been partially included in the mainline Linux kernel since version 2.6.36. Canonical has supported the development of AppArmor since 2009.
