Building an Incident Response Plan That Works

A solid incident response (IR) plan reduces chaos when something goes wrong—whether it's ransomware, a data breach, or a disruptive outage. The goal is clarity: who does what, when, and how. Too many IR plans sit on the shelf because they're outdated, too long, or not practiced. Here's how to build one that teams actually use and keep it current.

Define Roles and Contacts

Assign clear roles: incident lead (who runs the response), communications (internal and external, including legal and PR), technical containment (who isolates systems and preserves evidence), and legal/compliance (who advises on notification and regulatory obligations). Keep a contact list—internal and external, including legal, forensics, and cyber insurance—and update it at least quarterly. Test the list: can you reach everyone at 2 a.m.? If not, fix it before an incident.

Scenarios and Playbooks

Document steps for the scenarios you care about most: ransomware, business email compromise, data breach, DDoS, and insider threat. Short playbooks with decision points and escalation paths beat long manuals. Each playbook should answer: what are the first steps, who is notified, when do we escalate to leadership or external parties, and what evidence do we preserve? Keep playbooks in a place that's accessible during an incident (e.g., not only on a system that might be down).

Test and Update

Run tabletop exercises at least annually—and more often if you're in a high-risk or regulated industry. Tabletops don't require technical simulation; they're about walking through "what if" and validating that roles, contacts, and playbooks work. After any real incident, run a post-incident review and update the plan with lessons learned. If you need help designing or testing your IR plan, we can help.
