Which tool is a robust network threat detection engine capable of real-time intrusion detection, inline intrusion prevention, network security monitoring, and offline pcap processing?

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

Answer: (A)

Suricata is a high-performance network threat detection engine that can function as an IDS, an inline IPS, provide network security monitoring, and process offline PCAPs. It detects threats in real time by applying signature-based and protocol-anomaly rules to traffic, generating alerts as packets flow. When run in inline mode, it can actually drop or modify packets on the fly, providing intrusion prevention. For network security monitoring, Suricata outputs rich event data (such as EVE JSON) and flow information that can be collected, analyzed, and correlated to give deep visibility into network activity. It also handles offline PCAP processing by reading capture files (-r) and applying the same detection capabilities to historical traffic, which is invaluable for investigations and testing. While Snort can cover similar ground, Suricata’s multi-threaded design and built-in NSM outputs make it particularly well-suited to all four roles in a single tool. AlienVault OSSIM is a broader SIEM platform that integrates multiple sources, and Wifi Inspector focuses on wireless assessment rather than a comprehensive network threat engine.
