Immunix is a discontinued commercial operating system that provided host-based application security solutions. The last release of Immunix's GNU/Linux distribution was version 7.3 on November 27, 2003. Immunix, Inc. was the creator of AppArmor, an application security system.
On May 10, 2005, Novell acquired Immunix, Inc., a long-time partner with Novell.[1] AppArmor was one of Novell's primary interests, and as a result, it was adopted by the company and renamed Novell AppArmor powered by Immunix. In September 2007, Novell laid off the AppArmor team.[2]
