What are the 5 nist csf categories

The NIST Cybersecurity Framework (NIST CSF) consists of five core cybersecurity functions, not categories. These functions are the foundational building blocks for managing and improving cybersecurity within an organization. Each function serves a specific purpose in addressing cybersecurity risks and enhancing an organization's security posture. Here are the five NIST CSF functions:

  1. Identify:

    • This function involves understanding the organization's assets, data, and capabilities, as well as the associated cybersecurity risks. It includes activities such as asset management, business environment analysis, and risk assessment. The goal is to gain a clear understanding of what needs to be protected and the potential threats.
  2. Protect:

    • The Protect function focuses on implementing safeguards to ensure the security of the identified assets. It includes activities related to access control, data security, training and awareness, and protective measures. Protecting against cybersecurity threats is vital to maintaining the confidentiality, integrity, and availability of data and systems.
  3. Detect:

    • Detection involves identifying cybersecurity events or incidents in a timely manner. This function includes activities like continuous monitoring, anomaly detection, and incident detection and response capabilities. Detecting threats early allows organizations to respond quickly and minimize potential damage.
  4. Respond:

    • In the event of a cybersecurity incident, the Respond function outlines the necessary steps to take. It includes activities such as incident response planning, communication, analysis, mitigation, and recovery. The goal is to respond effectively to incidents to limit their impact and restore normal operations.
  5. Recover:

    • The Recover function focuses on restoring the organization's capabilities and services following a cybersecurity incident. Activities include recovery planning, improvements, and communication. The objective is to return to normal operations and ensure that lessons learned are applied to prevent future incidents.

These five functions together provide a comprehensive framework for organizations to manage and improve their cybersecurity posture. Organizations can tailor their efforts in each function to suit their unique needs, and the NIST CSF emphasizes the importance of continuous assessment and improvement to stay resilient against evolving cybersecurity threats.
