This book provides senior leaders with a comprehensive guide to implementing the NIST Cybersecurity Framework (CSF) in their organisations. It introduces the framework and its five core functions: Identify, Protect, Detect, Respond, and Recover. Each of these functions is explored in detail, including its key components and best practices for implementation.

The book also includes a detailed discussion of the Implementation Tiers, which provide a way for organisations to assess their cybersecurity maturity and identify areas for improvement. The four tiers are described, along with the criteria for achieving each one and the benefits of doing so.

Overall, this book is a valuable resource for senior leaders who want to improve their organisations' cybersecurity posture and align their practices with industry standards and regulatory requirements. It provides a clear roadmap for implementing the NIST CSF and reducing cybersecurity risks while protecting critical assets and information.
