Comment pouvez-vous tester et valider régulièrement votre plan de réponse aux incidents de cybersécurité et de reprise d’activité ?

Watch out - some things are often misunderstood. 1. Be clear on the best practices/standards. NIST CSF doesn't provide IR guidance. Be clear on which NIST guidance you're relying on. 2. Plan = roadmap. The latest NIST guidance defines the IR plan as a roadmap. IR procedures are simply "procedures". 3. What is your objective / and who is/are your executive sponsor(s)? These will drive your analysis. See below for additional tips on specific frameworks.

To test and validate your cybersecurity incident response and recovery plan regularly, establish a comprehensive testing and simulation program. Conduct tabletop exercises and simulated cyber-attacks, involving cross-functional teams to evaluate their ability to execute the plan effectively. Use varying scenarios to test different aspects of the plan, such as data breaches, malware infections, or denial-of-service attacks. Review and update the plan based on lessons learned from each exercise.

Testing and validating your cybersecurity incident response and recovery plan regularly is crucial to ensure its effectiveness in real-world scenarios. Some key steps and methods you can use to test and validate your incident response plan: • Tabletop Exercises • Simulation Drills • Penetration Testing • Red Team Exercises • Automation Testing • Scenario-Based Testing • Documentation Review • Communication Drills • Post-Incident Review • Regulatory Compliance Checks • Collaboration with External Entities • Continuous Training and Awareness

Key: Don't reinvent the wheel. 1. There are many best practice templates and standards out there. 2. If someone gives you tabletop materials/templates, check that they are aligned with best practices (e.g. NIST), and verify yourself. 3. Don't accept templates that reinvented wheel, and ignored best practice examples.

Run drills on critical systems and ensure the Board or Board’s independent technical rep is on hand to oversee the before, during and after.
