What is the NIST framework?

The National Institute of Standards and Technology (NIST) Cybersecurity Framework is a comprehensive guide for managing and reducing cybersecurity risks. Primarily, it's not a legal requirement but a voluntary framework developed to provide organizations, including K-12 educational institutions, with guidelines and best practices in cybersecurity.

Its voluntary nature is partly due to its broad applicability across various sectors, allowing flexibility for organizations to adapt it according to their specific needs and risk profiles. Mandating such a framework could potentially limit its adaptability and applicability, given the diverse cybersecurity needs and resource capabilities of different organizations.

The NIST Framework is structured around three main components:

Core Elements: These are the building blocks of the framework, providing a set of activities, desired outcomes, and informative references across various cybersecurity domains. The core is divided into five concurrent and continuous functions: Identify, Protect, Detect, Respond, and Recover.
Tiers: These provide a mechanism for organizations to view and understand the level of rigor and sophistication of their cybersecurity risk management practices. The tiers range from Tier 1 (Partial) to Tier 4 (Adaptive), reflecting a progression from informal, reactive responses to agile, risk-informed approaches.
Profiles: They enable organizations to establish a roadmap for reducing cybersecurity risk that is consistent with their mission, risk tolerance, and resources. Profiles can be used to identify opportunities for improving cybersecurity posture by comparing a “Current” profile (the “as is” state) with a “Target” profile (the “to be” state).

Why Use the NIST Framework for K-12 Environments
