Thread: New SSL/TLS State Machine




New SSL/TLS State Machine

Have a working string of sigs to identify a good ssl or tls
session.
They're targeted now at high ports, over 8081. The impetus
to create
this was a new bot that's using standard ssl for a command
and control
session on a high port. This catches that. 

If you're running ssl apps on high ports a suppress
statement for the
first sigs in the chain, or the data sigs at the end will
quiet it down
for you.

See the sigs here:

leedingsnort.com/cgi-bin/viewcvs.cgi/sigs/POLICY/POLICY_SSL_
TLS_on_High_Port?view=markup

Please let me know if you can run sessions without these
tripping. It's
set to get sslv2, sslv3, and most tls implementations. I'm
sure there's
more than that to catch.
