Which tool provides a robust network threat detection engine with IDS, IPS, and NSM features and supports offline pcap processing?

• A. Suricata
• B. Snort
• C. AlienVault OSSIM
• D. Wifi Inspector

Answer: (A)

Suricata is a robust, open‑source network threat detection engine that natively provides IDS, IPS, and Network Security Monitoring (NSM) capabilities. It can operate in IDS mode to passively monitor traffic and raise alerts, or in inline IPS mode to actively block malicious traffic. Its NSM features deliver rich visibility through detailed logs and protocol parsing, including file extraction and TLS/HTTP data, which helps you analyze and investigate threats beyond simple alerts. Suricata also supports offline pcap processing, so you can analyze captured traffic from PCAP files for forensics, rule testing, or training without relying on live traffic. While Snort is a solid IDS/IPS option, Suricata’s multi-threaded performance and built‑in NSM features make it a more comprehensive choice for environments that need both real-time detection and offline analysis. AlienVault OSSIM is a SIEM platform that aggregates data and may leverage IDS/IPS sensors, but it isn’t primarily a standalone threat detection engine with NSM and offline pcap processing. Wifi Inspector focuses on wireless security assessment rather than network threat detection.
