Name That Security Feature

Mark Cox from the “Security Response Team” at Red Hat has put up a chart of security features and when they first appeared in the various Fedora and Red Hat Enterprise releases. It gives me motivation for my project at work tomorrow where hopefully I can nuke the last two RHEL 3 systems under my control.

Also he has a brief overview of the security updates released in the first few months of the life of RHEL 5 and how various security features either mitigated or decreased the risk of successful exploitation for many of these issues.
