What is Suricata?
Suricata is a free and open-source network-based intrusion detection and prevention system (IDS/IPS) that utilizes a combination of signature and anomaly-based detection methods to identify and prevent potential security threats. It is designed to be highly scalable and can be used in a variety of environments, from small networks to large enterprise deployments.
Main Features
Some of the key features of Suricata include:
- Signature-based detection: Suricata uses a comprehensive signature database to identify known threats and alert on potential security incidents.
- Anomaly-based detection: Suricata also uses machine learning algorithms to identify unusual patterns of network traffic that may indicate a potential security threat.
- SSL/TLS inspection: Suricata can inspect encrypted network traffic, allowing it to detect threats that may be hiding in encrypted communications.
