Abstract
A method may include receiving a session control protocol request message and fingerprinting the received session control protocol message. The method may further include comparing the fingerprint of the received request message to a list of fingerprints associated with known malicious user agents and rejecting the request message when the fingerprint of the received message matches any fingerprint in the list of fingerprints associated with known malicious user agents. The method may include comparing the fingerprint of the received request message to the list of fingerprints associated with known non-malicious user agents and accepting the request message when the fingerprint of the received message matches any fingerprint in the list of fingerprints associated with known non-malicious user agents.
