Suricata: Open Source Intrusion Detection & Prevention System

Suricata is an open source intrusion detection and prevention system. It uses rules and signatures to monitor network traffic for anomalies and threats, and can generate alerts and block attacks in real-time.

What is Suricata?

Suricata is an open source intrusion detection and prevention system developed by the Open Information Security Foundation. It works by sniffing network traffic in real-time and running it against a set of predefined rules and signatures to identify potential threats and anomalies.

Some key features of Suricata include:

  • Real-time threat detection using signatures and rules
  • Protocol analysis for traffic on networks, TCP, UDP, ICMP, and IPSec
  • Anomaly detection capabilities
  • High performance and scalability using multi-threading
  • Capability to extract files and detect malware from network traffic
  • Integration with common tools like Snort rulesets, Emerging Threats, and VRT
  • Alerting, logging, reporting capabilities
  • Ability to act as an IPS and block attacks

Suricata can monitor individual hosts or entire networks for suspicious activity. Its detection capabilities coupled with active blocking make it well-suited as an IPS for protecting infrastructure and assets. Common use cases include network perimeter security, server protection, endpoint detection and response (EDR), Industrial Control System (ICS) protection, and more.
