Bro

What is Bro?

Zeek (formerly Bro) is a powerful network analysis framework that is much more than a typical intrusion detection system (IDS). Zeek analyzes network traffic in depth, providing a comprehensive record of network activity. It's commonly used for network security monitoring, intrusion detection, and incident response. Zeek uses a policy-driven scripting language to define custom analysis and detection logic. It differs from traditional IDS by providing a deep understanding of network behavior, rather than just relying on signature-based detection.
