The document discusses the NIST Cybersecurity Framework, which provides guidelines for critical infrastructure security and management of cybersecurity risks. It was created through a collaboration between government and industry to help organizations manage and reduce cybersecurity risks. The framework consists of five concurrent and continuous functions - Identify, Protect, Detect, Respond, Recover. It also outlines implementation tiers from Partial to Adaptive to help organizations determine their cybersecurity risk management practices. The framework is meant to be flexible and not prescriptive in order to accommodate different sectors and risks profiles.
