I have written seven IDS signatures that detect the default configuration
of stacheldraht, as presented in Dave's excellent writeup.  They are
available at Whitehats and below in this email.

This is probably a good opportunity to introduce my free IDS signature
database project, arachNIDS.  [ http://whitehats.com/ ]  arachNIDS is the
Advanced Reference Archive of Current Heuristics for Network Intrusion
Detection Systems - CVE and BugtraqID compatible/searchable.  The database
can be used as a tool for research, or IDS signatures can be exported for
use in free IDS such as Snort.

The intent of this open/free database is to raise the bar on modern
intrusion detection systems by bringing full-disclosure to IDS.  arachNIDS
is a work in progress, and contributions are very welcome.  I have also
created a Intrusion Event description form that, as you fill in packet
information, dynamically creates an appropriate signature.  Please visit
the site for details.
