SOAR Playbooks: Automating Incident Response

Automation in incident response is not a luxury - it is a necessity. When a critical alert arrives at 2 AM, you cannot wait for an analyst to wake up, read the log, triage, search for correlated IOCs, and decide what to do. Every minute counts. This is where SOAR (Security Orchestration, Automation and Response) playbooks make the difference.

In Presidio I use Shuffle SOAR with 5 playbooks covering the most common scenarios: brute force detection, malware alert triage, automatic IOC enrichment, case creation, and threat intelligence correlation. Every playbook was built iteratively - first a basic version, then refined after each real incident.

The perfect playbook doesn't exist

I learned that the perfect playbook is not the one that does everything automatically. It is the one that automates the repetitive parts and leaves critical decisions to the human. The brute force playbook, for example, automatically collects all IOCs, correlates them with MISP, creates the case in DFIR-IRIS with all data pre-filled, and prepares the blocking action - but the analyst must approve the block. Automation prepares, the human decides.

The most common mistake in SOAR implementation is trying to automate too much, too soon. I have seen organizations wanting 50-step playbooks for every alert type. The result: fragile playbooks that break every time something changes. Better 5 robust playbooks than 50 fragile ones.

The technical detail that makes the difference: error handling. Every step of the playbook must have a fallback. If MISP is not responding? The playbook continues with the data it has. If the case manager is down? The alert gets sent via an alternative webhook. The resilience of the playbook is as important as its logic.
