What are the three main elements of the NIST Cybersecurity Framework CSF )?

Core: The Core is the foundation of the NIST Cybersecurity Framework (CSF). It is a set of desired cybersecurity activities and outcomes that organizations can use to assess and improve their cybersecurity posture. The Core consists of five functions: Identify, Protect, Detect, Respond, and Recover. These functions provide a high-level, strategic view of the lifecycle of an organization’s management of cybersecurity risk.

Implementation Tiers: Implementation Tiers are used to describe an organization’s current cybersecurity posture and the desired target state. The four tiers – Partial, Risk-Informed, Repeatable, and Adaptive – provide a consistent means of assessing an organization’s cybersecurity preparedness. Each tier describes the level of rigor, resources, and processes needed for an organization to effectively manage its cybersecurity risks.

Profiles: Profiles are used to compare an organization’s current cybersecurity posture to its desired target state. Profiles are based on the organization’s business requirements, risk tolerance, and resources. They provide a roadmap for an organization to prioritize and focus its efforts on the most important cybersecurity activities. Profiles can be used to measure progress and track the organization’s performance over time.
