🤖 Automated SOAR Playbooks

Trigger: Phishing Alert
PB-001 — Phishing Response
  1. 1Extract IOCs from email headers & body
  2. 2Query TIP for malicious indicators
  3. 3Determine campaign scope via email gateway
  4. 4Quarantine confirmed mailboxes
  5. 5Block sender domains on NGFW & SWG
  6. 6Create incident ticket → notify client
Trigger: Ransomware Behavior
PB-002 — Ransomware Containment
  1. 1Correlate EDR telemetry for blast radius
  2. 2Network-isolate affected endpoints via EDR API
  3. 3Block C2 IPs on NGFW
  4. 4Initiate forensic memory capture
  5. 5Page on-call IR team (P1)
  6. 6Initiate client crisis communication
Trigger: Privilege Escalation
PB-003 — Privilege Escalation Response
  1. 1Query PAM for full session context
  2. 2Suspend account in Active Directory
  3. 3Collect correlated audit trail from SIEM
  4. 4Escalate to Tier 2 analyst for review
