The NIST Cybersecurity Framework (CSF) is a framework developed by the National Institute of Standards and Technology (NIST) to help organizations manage and reduce their cybersecurity risks. In addition to the core functions of the CSF, the framework also includes four levels or “tiers” that provide guidance on how organizations can implement the framework and improve their security posture. In this blog post, we’ll focus on the Partial tier, which is the first and lowest tier in the CSF.
The Partial tier indicates that an organization is just starting to implement the CSF and has basic controls in place. At this level, an organization may have some security controls in place, but they are not well-defined or consistently applied.
One of the key characteristics of the Partial tier is that an organization has a limited understanding of its risks and vulnerabilities. This may mean that the organization has not conducted a risk assessment, or that the risk assessment is not comprehensive or up-to-date. As a result, the organization may be unaware of its most pressing risks, and may not have implemented controls to mitigate those risks.
Another characteristic of the Partial tier is that an organization has a limited range of security controls in place. This may mean that the organization has implemented only a few of the controls from the CSF, or that the controls that are in place are not consistently applied. For example, an organization at the Partial tier may have implemented some access controls, but those controls may not be consistently applied across the organization.
Overall, the Partial tier is a starting point for organizations looking to implement the CSF and improve their security posture. By moving from the Partial tier to the higher tiers, organizations can improve their understanding of their risks, implement a broader range of security controls, and establish processes for implementing and maintaining those controls. This helps organizations reduce their risk of a successful cyber attack and protect their assets and sensitive data.
