Is there a way to disable SSL renegotiation at firewall level ?
Disabling it server side ( Microsoft Security Advisory: Vulnerability in TLS/SSL could allow spoofing ) breaks activeSync. I'd like to test a different scenario to get rid of the many false positives we get for the SSL Renegotiation Denial of Service Vulnerability.
According to the admin guide (page 178) you can setup custom IPS signatures based on SSL so I hope its possible to setup a vuln signature regarding ssl negotiation which you then block if this comes client -> server.
Unfortunately I currently dont have any example on how to setup such signature.
