The real-time session inspection method using heartbeat signal

摘要

In this paper, we present how to store the session information from the Heartbeat signal, which is generated at regular intervals during the network session, in real packet analysis tools. Since the existing session information retrieval method checks the session information at the end of the session, information cannot be confirmed in the case of an active session. To verify the information of the active session, this paper utilizes the heartbeat signal generated by the session every certain period. By analyzing active session information, it is possible to analyze information about flows and packets in a session in real time.
