Snort3

Snort 3 is the next-generation open-source network intrusion detection and prevention system (IDS/IPS) developed by Cisco, representing a complete architectural rewrite of the original Snort engine. It features multi-threaded packet processing, a shared object rule system, improved protocol normalization, and a Lua-based configuration and plugin framework that provides significantly better performance and extensibility than its predecessor. Network security engineers, SOC analysts, and managed security providers deploy Snort 3 to monitor network traffic in real time, detecting and blocking threats including exploit attempts, malware command-and-control traffic, policy violations, and protocol anomalies. With its massive community-maintained ruleset and deep packet inspection capabilities, Snort 3 remains one of the most widely deployed network security monitoring solutions in both enterprise and government environments.
