National Institute of Standards and Techonoglies, or NIST is a cybersecurity framework consisting of five functions: Identify, Protect, Detect, Respond and Recover.
The Identify Function assists in developing an organizational understanding to managing cybersecurity risk to systems, people, assets, data, and capabilities.
The Protect Function outlines appropriate safeguards to ensure delivery of critical infrastructure services.
The Protect Function supports the ability to limit or contain the impact of a potential cybersecurity event.
The Detect Function defines the appropriate activities to identify the occurrence of a cybersecurity event.
The Detect Function enables timely discovery of cybersecurity events.
The Respond Function includes appropriate activities to take action regarding a detected cybersecurity incident. The Respond Function supports the ability to contain the impact of a potential cybersecurity incident.
The Recover Function identifies appropriate activities to maintain plans for resilience and to restore any capabilities or services that were impaired due to a cybersecurity incident. The Recover Function supports timely recovery to normal operations to reduce the impact from a cybersecurity incident.
