Threat signatures requiring ssl decryption

L0 Member

Is there a way to determine if a threat signature requires ssl decrypt in order to provide protection. I undertsnad this could have at least three posibilities being fully required, partially required, and not required. Using signature 14616 in content version 608 as an example, I cannot determine if I will ever see hits on this threat ID if I don't leverage ssl decrypt on the session.

Non of the threat id's *require* that your traffic is decrypted, if it detects the signature then it will trigger. If it can't detect the signature because of the encryption then it will not trigger. 

Not a single signature will trigger on encrypted traffic. If you want to check encrypted traffic for threats, you MUST decrypt it. 


There is actually quite a few threat signatures that trigger based on packet header information

Yeah, signatures which check protocol compliance can still work.

But a short answer would be: if you want to check an encrypted session for possible threats, you have to decrypt it.
