Which assumption about a CSP should be avoided when considering risks in a disaster recovery (DR) plan?

When developing a disaster recovery (DR) plan, it is essential to approach the risks associated with a cloud service provider (CSP) with a clear understanding of their capabilities and history. Assuming the level of resiliency offered by a CSP can lead to significant vulnerabilities in your disaster recovery strategies.

CSPs may promote high levels of resiliency, but such claims can vary widely in reality. Factors like the architectural decisions made by the provider, the specific infrastructure used, and the geographical location of data centers can all influence how resilient a CSP's services truly are in the face of a disaster. As such, relying solely on the advertised level of resiliency without conducting a thorough evaluation can result in an overestimation of a CSP's abilities to recover from failures, which could leave your organization's critical data and operations at risk.

By not taking the provider's specific capabilities into account and solely making assumptions based on general statements of resiliency, an organization could find itself inadequately prepared in a disaster scenario. It is far more prudent to assess the historical performance of the CSP in disaster recovery scenarios, the continuity planning framework they employ, and how costs might fluctuate based on varying levels of service resilience.
