Re: NeVO Scan Application was RE: Cisco CTR

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.
