NIST CSF Overview and Guides

The NIST CSF Overview and Guides talk about the Cybersecurity Framework (CSF), which is voluntary guidance released by the National Institute of Standards and Technology (NIST) in 2014 for private sector organizations in the US and has been embraced by organizations around the world. CSF provides a uniform set of rules, guidelines, and standards for organizations across industries to better manage and reduce cybersecurity risks. If you worry about unseen risks and vulnerabilities, don’t have an accurate inventory of assets that need to be protected, and need a strategic cybersecurity plan, the NIST CSF can be a valuable resource. CSF represents the collective experience of information security professionals and is widely recognized as an industry best practice.

The framework was created as a voluntary measure to help private sector organizations secure their IT infrastructure. By providing a common language to address cybersecurity risk management, CSF aims to enhance cybersecurity communication inside and outside the organization.

The CSF categorizes all cybersecurity capabilities, projects, processes, and daily activities into three main components:

1. Framework Core: It is a set of cybersecurity activities. The functions are applicable not only to cybersecurity, but to an overall risk management program. The categories are broad cybersecurity objectives that are further detailed within the subcategories.
2. Implementation Tiers: The tiers refer to the degree to which an organization meets the characteristics described in the framework. The tiers do not represent maturity levels but rather the degree of rigor and how well cybersecurity is integrated into risk decisions.

1. Profiles: They enable each organization to create a roadmap for reducing cybersecurity risks.

The Core represents the cybersecurity activities of the organization, the Profiles provide an opportunity to identify areas where existing processes are strengthened or implemented; and the Tiers provide context on how an organization views cybersecurity risk management.

Aligning with the framework provides a common language and systematic methodology for managing cybersecurity risk.
