About:
Zeek is a powerful network analysis framework that differs from typical IDSes by focusing on network state and protocol analysis rather than just signature matching. It passively monitors network traffic and produces structured, high-fidelity logs that detail network activity. This enables deep forensic analysis and proactive security monitoring.
|
Key Features:
- Passive network traffic analysis
- Protocol analysis and logging
- Scripting language for custom analysis
- Scalable for high-speed networks
- Generates structured logs (conn, http, dns, etc.)
|
Use Cases:
- Network security monitoring and intrusion detection
- Incident response and digital forensics
- Network troubleshooting and operational visibility
- Traffic analysis and application monitoring
|
Alternatives:
-
Suricata
– Suricata is a signature-based IDS/IPS with real-time blocking, while Zeek excels at protocol analysis and stateful logging for deep forensic capabilities.
-
Wireshark
– Wireshark is a packet capture and analysis tool for interactive inspection, whereas Zeek is designed for continuous, automated monitoring and logging of network-wide activity.
