Suricata is an open-source network intrusion detection and prevention system (IDS/IPS) developed by the Open Information Security Foundation (OISF). It uses rules and signatures to detect potential threats and malicious activity on networks in real-time. Suricata can analyze network traffic, packet payloads, and metadata to identify attacks such as malware infections, data exfiltration attempts, denial-of-service attacks, and more. It supports various protocol analysis features including HTTP, DNS, SMTP, TLS/SSL, SSH, and others. Suricata is widely used in enterprise environments for threat detection and response.
