Cyber Resilience
Cyber Resilience (CR) is an evolving information security concept that focuses on an entity's ability to withstand and maintain operations during and after a cyber incident. Resilience, as defined by Presidential Policy Directive PPD-21, is the ability to prepare for and adapt to changing conditions and withstand and recover rapidly from disruptions. Cyber Resilience focuses on the preventative, detective, and reactive controls in an information technology environment to assess gaps and drive enhancements to the overall security posture of the entity.

The Cyber Resilience Review (CRR) is one framework for the assessment of an entity's resiliency created by the Department of Homeland Security. Another framework created by Symantec is based on 5 pillars: Prepare/Identify, Protect, Detect, Respond, and Recover.
