CGRC · Question #549
Which term (Sensitivity or Criticality) normally places emphasis on availability and most often relates to the amount of time an organization can tolerate the non-availability of the system? Response:
The correct answer is A. Criticality. Criticality places emphasis on availability and directly relates to the amount of time an organization can tolerate a system's non-availability. Sensitivity, in contrast, primarily focuses on data confidentiality.

Why each option
Criticality places emphasis on availability and directly relates to the amount of time an organization can tolerate a system's non-availability. Sensitivity, in contrast, primarily focuses on data confidentiality.
Criticality refers to the importance of an information system or its functions to an organization's mission and business operations, with a strong focus on uninterrupted availability. Systems categorized as critical are those whose non-availability would cause severe impact, and their criticality is often defined by the maximum tolerable downtime or recovery time objectives (RTOs). This term directly quantifies how indispensable a system is to continuous operations and how long an organization can endure its unavailability.
Sensitivity relates to the confidentiality of information, indicating the potential harm from unauthorized disclosure, not the impact of system non-availability.
Availability is a security objective (part of the CIA triad), but 'criticality' is the term used to describe the degree of importance tied to the tolerance for non-availability.
Sensitivity, as noted previously, pertains to confidentiality.
