Certified Information Security Manager (CISM)Incident ManagementMedium
A CISO is developing a disaster recovery plan (DRP) for an organization that operates in a highly regulated industry. The organization relies heavily on several third-party cloud providers for critical services. The CISO is concerned that the DR capabilities of these providers may not align with the organization's specific RTO/RPO requirements and regulatory obligations. Which of the following is the MOST effective approach for the CISO to ensure alignment?
- ARequiring third-party providers to submit their internal DR plans for review.
- BConducting joint disaster recovery exercises with key third-party providers.
- CNegotiating stricter Service Level Agreements (SLAs) with penalty clauses.
- DImplementing a shadow IT recovery environment independent of the providers.
Show answer & explanationAnswer & explanation
Correct answer: B. Conducting joint disaster recovery exercises with key third-party providers.
Joint DR exercises directly validate whether the third-party providers' recovery capabilities actually meet the organization's RTO/RPO and regulatory needs in a real-world simulation, making it the most effective way to ensure alignment.
Why the other options are wrong
- A. Reviewing internal plans provides documentation but doesn't validate actual performance or alignment with *your* specific requirements.
- C. SLAs define contractual obligations and penalties but don't guarantee actual performance or alignment, especially for complex regulatory needs. Exercises prove performance.
- D. Implementing a shadow IT recovery environment is costly, complex, and goes against leveraging cloud providers, creating new management burdens.
Third-Party DR Alignment
Ensuring that the disaster recovery capabilities and plans of third-party vendors and cloud providers meet an organization's specific recovery objectives and regulatory compliance requirements.
- Critical for organizations relying on external services.
- Requires validation beyond contractual agreements.
- Joint exercises are a key validation method.
Memory trick: Don't just trust; test jointly for third-party DR readiness.
