Any UNIX security references/mailing-lists ?

Hi, Can anyone suggest some good references/mailing-lists about UNIX security ? I've already read lots of popular papers/books, such as "practical unix security", "improving UNIX security",internet worm, race condition to gain root permission, phrack(25), CERT, etc. I heard that there exists some references circulated among the SAs only, such as Neil Gorsuch mailings, right ? I doubt if there any way to get some ? -- Chong-kan Chiu The Chinese University of Hong Kong Shatin, Hong Kong E-mail address : ckchiu@cs.cuhk.hk
