Historically, active vulnerability scanning of network printers and older Novell NetWare servers could be problematic. Sometimes a simple port scan with any type of auditing tool would cause a network printer to print paper, crash or interrupt real print jobs. Similarly, older Novell NetWare installs were also subject to crashing when having their servers fingerprinted.

Greetings!
In this column, and in subsequent columns, I am going to develop a set of themes about cyber-stuff. We've all heard a great deal of kerfluffle about cyberterror or cyberwar, but - what, really, is it?

In the next few weeks, I will be posting a series of blog entries which provide examples of analyzing logs and events in large enterprise networks.

Previously, I posted a blog which showed how Nessus Direct Feed and Security Center users could audit Windows XP Pro systems against FDCC compliance settings. In this blog entry, we will show how this can also be accomplished for Windows Vista systems. As with the previous blog, we will be performing audits against the reference Virtual PC systems available from NIST.
