Incident Response: Building and Testing a Plan
Introduction
No organization is immune to cyber incidents. A robust Incident Response (IR) plan ensures quick action to minimize damage and recover effectively.
Key Components of an Incident Response Plan
- Preparation:
- Establish a team with defined roles.
- Conduct training and scenario-based exercises.
- Detection and Analysis:
- Use monitoring tools to detect anomalies.
- Categorize incidents by severity.
- Containment and Eradication:
- Isolate affected systems.
- Remove malicious files or unauthorized access.
- Recovery:
- Restore systems from backups.
- Validate that vulnerabilities have been resolved.
- Lessons Learned:
- Conduct post-incident reviews.
- Update the plan based on findings.
Why Testing is Critical
Regular testing, such as tabletop exercises, identifies weaknesses and ensures the team is prepared for real-world scenarios.
