name: implementing-soar-playbook-with-palo-alto-xsoar description: Build automated incident response playbooks in Cortex XSOAR (Demisto) using its YAML playbook structure, integration commands, and task types to orchestrate phishing, malware, account-compromise, and DDoS response workflows across SOC tools. Use when authoring or wiring up an XSOAR playbook, adding custom XSOAR integration commands or Python automation scripts, or reducing manual SOC response time via orchestration. domain: cybersecurity subdomain: soc-operations tags:
Cortex XSOAR (formerly Demisto) is Palo Alto Networks' Security Orchestration, Automation, and Response platform. Playbooks are the core automation engine in XSOAR, enabling SOC teams to automate repetitive incident response tasks. XSOAR provides 900+ prebuilt integration packs, 87 common playbooks, and a visual drag-and-drop editor for building custom workflows. Organizations using SOAR automation reduce mean time to respond (MTTR) by 80% on average.

Trigger: Malware alert from EDR
Steps:
1. Extract file hash, process details, host info
2. Enrich hash via VirusTotal, Hybrid Analysis
3. Check if file is on allowlist
4. If malicious:
a. Isolate endpoint via EDR
b. Block hash on all endpoints
c. Search for hash across environment
d. Create incident ticket
5. If clean: Close as false positive
Trigger: Impossible travel or suspicious login alert
Steps:
1. Get user details from Active Directory
2. Get login history for past 30 days
3. Check for impossible travel (geo-distance vs time)
4. Check for known VPN/proxy IP
5. If compromised:
a. Disable AD account
b. Revoke all OAuth tokens
c. Reset MFA
d. Notify user's manager
e. Search for lateral movement
6. If false positive: Document and close
Trigger: Network anomaly alert
Steps:
1. Verify traffic spike from network monitoring
2. Identify source IPs and geolocation
3. Check if source IPs are known botnets
4. Implement rate limiting on WAF
5. If sustained attack:
a. Enable upstream DDoS protection
b. Activate CDN scrubbing
c. Notify ISP if needed
6. Monitor and document
