LanguageProject Introduction
Summary
Suricata is a leading open-source network security engine designed for speed and scalability. Developed by the OISF and community, it offers robust capabilities for detecting network intrusions, preventing threats, and providing deep network visibility.
Problem Solved
Organizations face persistent network threats including malware, intrusions, and data exfiltration. Suricata provides essential visibility and control over network traffic to detect, prevent, and investigate these security incidents effectively.
Core Features
Signature Matching (IDS)
Inspect network traffic for malicious patterns using a powerful rule engine.
Inline Intrusion Prevention (IPS)
Block or drop malicious traffic based on configured rules, preventing network compromise.
Network Security Monitoring (NSM)
Log network events, flow information, and extracted files for detailed security analysis.
Protocol Identification
Automatically identify and parse a wide range of network protocols.

使用场景
Suricata can be deployed in various network environments and architectures to fulfill different security requirements:
Use Case 1: Passive Network Monitoring and Alerting
Details
Deploy Suricata in IDS mode to monitor traffic passively, generating alerts for suspicious activity without impacting network flow.
User Value
Gain visibility into potential threats and policy violations for proactive security response.
Use Case 2: Active Intrusion Prevention
Details
Implement Suricata in IPS mode inline to actively block or drop malicious packets before they reach internal systems.
User Value
Automatically stop known attacks and malware propagation, reducing the attack surface.
Use Case 3: Network Security Forensics and Analysis
Details
Leverage Suricata's NSM capabilities to capture detailed logs (flows, files, protocol data) for incident investigation and compliance.
User Value
Provide rich data sources for retrospective analysis of security incidents and understanding network behavior.
