Zeek SSL

Zeek's SSL (Secure Sockets Layer) log captures details about SSL/TLS sessions on a network, providing visibility into encrypted communications. This log is particularly useful for security analysis, as it reveals information about certificate usage, cipher suites, and connection properties, even if the actual data is encrypted. Zeek’s ssl.log helps monitor SSL/TLS traffic for unusual or potentially risky behavior, such as expired certificates, weak encryption, or unusual patterns in the frequency or duration of SSL sessions.
