Ron,

Didn't @Stake produce AntiSniff to detect passive type monitoring
applications ??

Woah ... no-one should be able to detect NeVO or RNA (or a NIDS) just by
sitting there. You need to do real complex things invoking timing and
other checks to find hosts that are passively listening.

Desktop agents like Sygate will see scans from Nessus, Nmap, pings, etc.
but they will have a hard time detecting passive analysis of their
network traffic.
