RE: VERY simple 'virtual' honeypot

["Ofir Arkin" <ofir () sys-security com>]

Lance, 

In my opinion it will be missing the main point of a Honeynet.

We all know that we can cut the foreplay pretty fast (scanning, probing)
and hit the site with an exploit even without the scanning attempt (read
this in the context :P). But than what? Exploit fails, not much
information gained, and we miss the funny part.

Just my thoughts.

Subject: [Snort-users] VERY simple 'virtual' honeypot

Most honeypots work on the same concept, a system that has no
production activity.  You deploy a box that has no production
value, any packets going to that box indicate a probe, scan, or
attack.  This helps reduce both false positives and false
negatives.  Exampls of such honeypots include BackOfficer Friendly,
DTK, ManTrap, Specter, and Honeynets.

However, I was just thinking, why bother deploying the box?
Why not create a list of Snort rules that generate an alert
whenever a TCP/SYN packet or UDP packet is sent to an IP
address that has no system?  This could incidate a probe,
scan or attack, the same principles of a honeypot, but
without deploying an actual system.

Of course this does not give you the Data Capture capabilites
of a honeypot, as there is no system for the attacker to
interact with.  However, this could be used to help detect
scanning or probing activity.

Thoughts?
