About Snort

Snort inspects network traffic in real time against a rule set, detecting and optionally blocking known attack patterns, protocol anomalies and policy violations. Community rules are free and a subscriber rule set is published earlier.

Strengths

  • Mature rule language and a large body of community and vendor rules
  • Runs in detection or inline prevention mode

Limitations

  • Rule tuning is required or the alert volume is unusable
  • The subscriber rule set, with the newest rules, is paid
