Question

While studying an organizations risk management process under the NIST Cybersecurity Framework, Rob determines that the organization adapts its cybersecurity practices based on lessons learned and predictive indicators derived from previous and current cybersecurity actitivies.

What tier should be assign based on this measure?
A.Tier 1
B.Tier 2
C.Tier 3
D.Tier 4

Answer 1

An organization that adapts its cybersecurity practices based on lessons learned and predictive indicators aligns with Tier 3 of the NIST Cybersecurity Framework, known as the 'Repeatable' level.

Step-by-step explanation:

Based on the description of the organization's risk management process under the NIST Cybersecurity Framework, where Rob determines that the organization adapts its cybersecurity practices based on lessons learned and predictive indicators derived from previous and current cybersecurity activities, the appropriate tier to assign would be Tier 3. This is because Tier 3, which is known as the 'Repeatable' level, is characterized by an organization's formal and consistent risk management practices that are informed by prior experiences and information gleaned from external sources. This allows the organization to manage risk in a repeatable and proactive manner. Therefore, when an organization actively adjusts its cybersecurity policies and actions as a result of analyzing and understanding past activities and outcomes, it aligns well with the definition of Tier 3 within the NIST Cybersecurity Framework.

Answer 2

The appropriate tier based on the organization's adaptation of cybersecurity practices through lessons learned and predictive indicators would be C. Tier 3.

Explanation:

Tier 3 in the NIST Cybersecurity Framework signifies an organization that demonstrates a proactive and adaptive approach to cybersecurity. This tier involves the utilization of lessons learned and predictive indicators derived from previous and current cybersecurity activities. It reflects a matured state where cybersecurity practices are regularly reviewed and improved based on a comprehensive understanding of potential risks. This level of adaptive response is indicative of a well-developed risk management process within the organization.

Tier assignment in the NIST Cybersecurity Framework is based on the organization's cybersecurity risk management practices. Tier 1 represents a basic level where practices are reactive, while Tier 2 indicates a more aware state where there's a formalized approach. However, Tier 4 signifies an organization with a fully integrated and dynamic approach that is more advanced than the description provided. Tier 3, therefore, best aligns with an organization that actively learns from previous incidents and uses predictive indicators to adapt its cybersecurity practices, creating a more resilient security posture.

To assess the tier placement accurately, considerations are made regarding the organization's risk management process, including its ability to foresee potential risks through predictive indicators and leverage past experiences to enhance cybersecurity measures. Tier 3 encapsulates these criteria, representing a stage where cybersecurity practices are adaptive and continuously evolving based on acquired knowledge and insights from previous and current cybersecurity activities. Therefore, the correct option is c.
