Experience in-depth coverage of Unix security issues. Examine how to mitigate or eliminate general problems that apply to all Unix-like operating systems including vulnerabilities in the password authentication system, file system, virtual memory system, and in common network protocols such as NFS, NIS, and the Unix RPC mechanism. Learn the exact steps necessary to secure the two most common Unix flavors-- Solaris and Linux-- and get specific advice for securing some of the most common Internet services on the Unix platform, including Apache, WU-FTPD, Sendmail, and BIND.
Throughout this course, you will become skilled at utilizing freely available tools to handle security issues, including SSH, AIDE, sudo, lsof, and many others. SANS' practical approach with "hands-on" exercises every day ensures that you can start using these tools as soon as you return to work. We will also put these tools to work in a special section that covers simple Forensic techniques for investigating compromised systems.
