The NIST CSF is a framework for organizations to manage and mitigate cybersecurity risk based on existing standards, guidelines, and practices. With this pocket guide you can: - Adapt the CSF for organizations of any size to implement - Establish an entirely new cybersecurity program, improve an existing one, or simply provide an opportunity to review your cybersecurity practices - Break down the CSF and understand how other frameworks, such as ISO 27001 and ISO 22301, can integrate into your cybersecurity frameworkBy implementing the CSF in accordance with their needs, organizations can manage cybersecurity risks in the most cost-effective way possible, maximizing the return on investment in the organization's security. This pocket guide also aims to help you take a structured, sensible, risk-based approach to cybersecurity.
