The new Systems Administration Networking and Security top 20 list has been released a couple of days ago.
This SANS Top-20 2004 is actually two Top Ten lists: the ten most commonly exploited vulnerable services in Windows and the ten most commonly exploited vulnerable services in UNIX and Linux.
The SANS Top-20 is a living document. It includes step-by-step instructions and pointers to additional information useful for correcting the security flaws.
