Hello list

Does anyone have any experience with writing
signatures for McAfee IPS systems?  It's a bit
frustrating compared to a system like Snort, because
the vendor-supplied sigs are "secret sauce".  I
can't just look in there for examples similar to
what I'm trying to achieve.

What I'm after in this case should in principle be
relatively simple - I want to catch certain function
calls in an HTTP response, but only in the context
of a javascript block.  I'd like to avoid tripping
the signatures if the same strings come up in the
regular text of a page, e.g. a in a mailing list
posting describing an IDS signature or a browser
vulnerability...

Mark

PS - kindly cc me on replies, as I'm not subscribed
