In your list are you including commercial products that passively fingerprint Operating Systems? If so, NFR's been passively fingerprinting Operating Systems since the release of 3.2 early this year (we're now on 4.0). In 3.2, it was primarily used for fragmentation re-assembly purposes, but in 4.0 it's also used for user information purposes as well, and is included in all tcp based alerts. Of course, NFR is not specifically a passive fingerprinting tool, but it's an example of how passive fingerprinting is used in real world scenarios.

Hey Mark, LTNS ! I was under the impression that anti-sniff was (thinking of a polite word) prone to false positives. Furthermore, I'd be tempted to deploy a passive OS fingerprinting tool on a Data In Nothing Out (DINO) tap, this would make the detection of the pf tool even more difficult through such measures. I think most IDS vendors are developing such technology (with one almost definite exception) But as usual Ron and Marty are ahead of the drag curve. I think it's really s3xy but as my wife will testify I'm sad and I need a life ;o) So s3xy that I have included a page detailing them all at http://www.securitywizardry.com/osfp.htm P0f Ettercap ARCHAEOPTERYX RNA NEVO Prelude pfprintd Disco There was one that was a predecessor I think to P0f but it is no longer supported so I left it out cheers Mark Are you anywhere near DC 11/12 Dec for a beer? -andy cuff Talisker Security Tools Directory http://www.securitywizardry.com----- Original Message ----- From: "Teicher, Mark (Mark)" <teicher () avaya com>To: "Ron Gula" <rgula () tenablesecurity com>; <focus-ids () securityfocus com> Sent: Thursday, November 20, 2003 7:49 PM Subject: RE: NeVO Scan Application was RE: Cisco CTRRon, Didn't @Stake produce AntiSniff to detect passive type monitoring applications ?? /mark -----Original Message----- From: Ron Gula [mailto:rgula () tenablesecurity com] Sent: Thursday, November 20, 2003 12:45 PM To: Teicher, Mark (Mark); focus-ids () securityfocus com Subject: 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.

Wondering if the Enterprise/Desktop firewall products can detect NeVO scans as they can nmap scans. It will be very interesting to see how Desktop firewalls in the corporate environment stand up to NeVO scans.. Something to try in the lab against all those Enterprise/Desktop Firewall products.. :) /mark -----Original Message----- From: Ron Gula [mailto:rgula () tenablesecurity com] Sent: Thursday, November 20, 2003 7:38 AM To: focus-ids () securityfocus com Subject: Re: Cisco CTR At 04:54 AM 11/20/2003 -0700, Mark Teicher wrote:Just curious on how NeVO compares to Intrusec Expose ??I have not seen Expose recently, but my thought was that it was a continuous low-volume active scan that could launch other vulnerabilityscanners when change was detected. NeVO does the same sort of thing, but passively through network packet/session monitoring. Besides looking for change in the network, it also looks for the vulnerability.NeVO needs to wait for a packet to be sent before it sees a host, port,client, server or vulnerability. If folks deploy NeVO with a Lightning Console, they can launch distributed Nessus scans if they see a system or a vulnerability data that they would like to follow up with an active scan.
