Novell has released Linux security software to make it harder for internet attacks to compromise existing Linux-based computers.
The AppArmor software limits a running application's privileges to those which are absolutely necessary.
Novell's main Linux rival Red Hat is doing something similar with its SELinux tool, which was added to Red Hat Enterprise Linux last year.
AppArmor is now available for download and will be integrated into Novell’s OpenSuSE system from next week.
The Novell security solution is based on technology that Novell acquired when it purchased the Linux security company Immunix last year.
AppArmor allows an administrator to create a profile to describe which files any application can use. The software then enforces these rules.
As a result, if a remote attacker manages to take over an application over the internet, it’s more difficult for the attacker to use that application to take over the entire computer.
Novell said that the open-source AppArmor tool took up fewer system resources than Red Hat’s solution and offered greater automation.
