Network Traffic Analysis

Network monitoring provides crucial visibility into communication patterns and data movement:

Network Detection Methods:

Signature-Based Detection: Identifies known attack patterns

  • Pros: High accuracy for known threats
  • Cons: Cannot detect zero-day attacks
  • Tools: Snort, Suricata

Anomaly-Based Detection: Identifies deviations from baseline behavior

  • Pros: Can detect unknown threats
  • Cons: Higher false positive rate
  • Tools: Darktrace, Vectra AI

NetFlow Analysis: Examines traffic metadata

  • Pros: Low storage requirements, broad visibility
  • Cons: Limited detail, no packet contents
  • Tools: SiLK, nfdump
