About:
Snort is an open-source network intrusion detection and prevention system that analyzes network traffic in real-time. It uses a rules-based language to detect various types of attacks, including port scans, buffer overflows, and SMB probes. It provides detailed packet logging and alerting capabilities for deep network analysis.
Key Features:
  • Real-time traffic analysis and packet logging
  • Extensible rule-based detection language
  • Protocol analysis and content searching
  • Community and commercial rule support
Use Cases:
  • Monitoring network perimeter for malicious activity
  • Forensic analysis of network traffic captures
  • Detecting specific application-layer attacks
Alternatives:
  • Suricata – Multi-threaded engine often cited as a high-performance alternative to Snort
  • Zeek (formerly Bro) – Focuses more on network traffic analysis framework than signature-based detection
