The NIST Cybersecurity Framework, developed by the National Institute of Standards and Technology (NIST), is a widely adopted framework that provides guidelines, best practices, and standards to help organizations manage and improve their cybersecurity posture. The framework offers a risk-based approach to cybersecurity and consists of core functions, categories, and subcategories that organizations can use to assess their current security posture, identify gaps, and establish a robust cybersecurity program. It emphasizes the importance of identifying, protecting, detecting, responding to, and recovering from cyber threats.
