Linux Advisory Watch Thank you for reading the Linux Advisory Watch Security Newsletter. The purpose of this document is to provide our readers with a quick summary of each week's vendor security bulletins and pointers on methods to improve the security posture of your open source system. Vulnerabilities affect nearly every vendor virtually every week, so be sure to read through to find the updates your distributor have made available.

Free Online security course (LearnSIA) - A Call for Help - The Survivability and Information Assurance (SIA) course was originally developed by a team at Carnegie Mellon, led by Lawrence Rogers (http://www.cert.org/sia/). Back in 2010, I requested a license to continue the development of the course because it provides useful information on Information Assurance. Also, this course will always be freely available for anyone to use in the classroom or self-study. There are three parts to the LearnSIA curriculum.
