This structured progression helps organizations allocate resources more effectively and ensures that each step builds on previous efforts, creating a cohesive and comprehensive security strategy.
NIST Cybersecurity Framework: A Comprehensive Approach
The NIST Cybersecurity Framework (CSF) was first released in 2014, defining five core functions: Identify, Protect, Detect, Respond, and Recover. This framework provides a comprehensive approach to managing cybersecurity risks, integrating technical, operational, and strategic aspects of security. The release of the NIST CSF marked a significant milestone in cybersecurity, promoting a holistic view of cybersecurity that extends beyond technical defenses to encompass broader organizational strategies.
In its 2024 update, NIST CSF 2.0 introduced a sixth core function: Govern. This addition underscores the importance of integrating cybersecurity into an organization’s overall governance and strategic priorities. The Govern function focuses on establishing clear risk management expectations, strategies, and policies, ensuring that cybersecurity efforts align with broader business objectives. By emphasizing governance, NIST CSF 2.0 highlights the critical role of executive leadership in driving and sustaining effective cybersecurity practices.
The comprehensiveness of the NIST Cybersecurity Framework lies in its ability to guide organizations through each stage of threat management.
