Security features in opensuse 10.X?

Hello! I could not really find good information about the security features of the next 10.1 version from the Wiki. I'm personally very interested in 1) Easy access control systems (I do not know what these could be... but could be easier than current) 2) Easy way of sandboxing servers, like limiting SFTP to some folder and it's subfolders. 3) File and folder access auditing - very much needed feature in corporations!! A must have. 4) Scanning tools, like NMAP and Nessus (nmap is available from Guru YaST repository, but Nessus is not from anywhere AFAIK - except manually from nessus.org, I guess) So, can somebody elaborate on these features and their future in (OSS) SUSE Linux? -- HG.
