Abstract
An inline malicious traffic detector captures handshake messages in a session with a security protocol. The inline malicious traffic detector comprises a classifier that generates a verdict for the session indicating malicious or benign. The classifier is trained on labelled sessions using custom features generated from handshake messages. Based on determining that the session is malicious using features of the handshake messages, the inline malicious traffic detector blocks the session.
