Many thanks for answers. Yes, i`ve got a portscan alerts of preprocessor sfportscan, and i think, thereis some reason for a rules detection an addition. What necesary to give a scan possible? I`de like to prevent it at all.

But what I have seen - based on limited testing - and some discussions over the Nessus forums, is that Nessus would enable/disable plugins automatically based on the services/ports/applications discovered even if I explicitly enable/disable plugins. I have seen the rules I mentioned earlier trigger on PCI scans, Advanced Network Scans, and Web Application Scans. This makes me believe that these are triggering during the initial discovery phase of a Nessus scan. However, I haven't verified this assumption by capturing packets or otherwise.

While these signatures do not identify that a Nessus scan in particular is ongoing, but the fact of seeing them trigger together is indicative of a Nessus scan in all cases I encountered. I will have to dig up some old data to get the sid(s) of these signatures.

Nessus doesn't actually send exploits at a machine, it scans for the presence of characteristics that would make the machine vulnerable to an exploit. There's nothing for Snort to detect, except the portscan part really. --Joel Esler Manager, Threat Intelligence and Open SourceTalos GroupSent from my iPhone On Jul 23, 2015, at 1:17 AM, Oleg Ruso <soy_siberiano () yahoo com> wrote: Hi List! snort-2.9.7.0 I`m looking for some Snort rules for a Nessus activity detection. Got an another alerts, but my Snort does not reveal a Nessus activity. The preprocessor sfportscan detection only i see.
