Understanding Incident Response
Incident response (IR) is the systematic process organizations follow when a cybersecurity event occurs. Based on the NIST framework, IR follows six phases: preparation, detection and analysis, containment, eradication, recovery, and post-incident review. The goal is to minimize damage, reduce dwell time (how long an attacker remains in the environment), preserve evidence for investigation, and restore normal operations as quickly as possible.
An incident response plan documents the procedures, roles, communication protocols, and escalation paths the organization will follow during an incident. Without a tested plan, organizations waste critical time during incidents figuring out who does what, how to communicate, and what steps to take -- time that allows attackers to cause significantly more damage.
Building IR Capability
Effective incident response requires three elements: a documented plan, a trained team, and regular testing. Tabletop exercises (simulated scenarios discussed around a table) test decision-making and communication. Technical exercises test the team’s ability to perform forensics, contain threats, and restore systems. Organizations without dedicated IR staff should maintain a retainer with an external IR provider who can respond within hours when an incident occurs.
Incident Response in San Diego
San Diego businesses benefit from a strong local cybersecurity ecosystem for incident response. Local IR providers can be on-site within 2-4 hours, critical when containing an active breach. HIPAA-covered entities must report breaches within 60 days. Defense contractors must report cyber incidents to the DoD within 72 hours. Having a local IR provider on retainer ensures compliance with these notification timelines while providing faster containment and recovery.
