Incident Response
The structured process for detecting, containing, eradicating, and recovering from a cybersecurity breach.
Definition
What is Incident Response?
Incident Response (IR) is the organized approach to addressing and managing the aftermath of a cybersecurity attack or data breach. The goal is to limit damage, reduce recovery time and cost, and prevent future incidents. A formal IR program follows the NIST Computer Security Incident Handling Guide (SP 800-61) lifecycle: Preparation, Detection and Analysis, Containment, Eradication, Recovery, and Post-Incident Activity. Effective IR requires pre-established playbooks, trained personnel, and often a retainer relationship with an external IR firm for surge capacity.
Why It Matters
When a breach occurs, every hour matters. IBM's Cost of a Data Breach Report consistently shows that organizations with incident response plans and teams contain breaches 54 days faster than those without — translating directly to millions of dollars in cost savings. Regulators including HIPAA, PCI DSS, SEC, and GDPR impose strict notification timelines (72 hours to weeks) that cannot be met without a pre-established IR process. Organizations that discover incidents without a response plan in place routinely make containment decisions that worsen outcomes — preserving evidence incorrectly, failing to isolate systems, or communicating prematurely.
How It Works
IR begins before a breach with preparation: documented playbooks, tabletop exercises, communication trees, legal and insurance contacts, and retainer agreements with external responders. During an active incident, the IR team executes triage (is this a real incident?), containment (stop the bleeding), eradication (remove the adversary), recovery (restore operations), and forensics (understand what happened and how to prevent recurrence). Post-incident, a lessons-learned review drives control improvements.
Our Approach
