Re: Tutorial of the Month
June 2010 - Apparmor
What a subject.. We'll step out of the T&T section this month to visit the Security Discussions area.
bodhi.zazen spends a lot of time in this section, educating and providing support.
apparmor (Application Armor) does what its name suggests, it helps protecting the system if an application gets compromised. apparmor works with specific application profiles that regulate and define the applications access in addition to the usual system permissions (which apparmor can only restrict).
By default, Ubuntu comes with apparmor profiles for CUPS, evince, dhclient3, firefox (which is not enabled) and the guest session.
The first thread to read is Introduction to AppArmor which is closed for posting.
Two other threads are open for discussion: Share your AppArmor Profiles and AppArmor Support Thread.
Enjoy the readings, test it out and report back in the threads!
