Analyzing Network Traffic for Incidents

When to Use

• SIEM alerts on anomalous network traffic patterns requiring deeper investigation
• C2 beaconing is suspected and needs confirmation through packet-level analysis
• Data exfiltration volume or destination must be quantified from network evidence
• Lateral movement between systems needs to be traced through network connections
• An IDS/IPS alert requires packet-level validation to confirm or dismiss

Do not use for host-based forensic analysis (process execution, file system artifacts); use endpoint forensics tools instead.
