During an annual assessment, numerous high-risk findings are discovered on a critical organizational system. The system's Federal Information Processing Standard (FIPS) 199 rating is "high" integrity,

The authorizing official (AO) is ultimately responsible for making a risk-based decision to authorize the operation of an information system. With numerous high-risk findings, a "high" FIPS 199 rating for confidentiality and integrity, and a very low risk tolerance, the AO must prioritize reducing the risk to an acceptable level before granting authorization, even if it means denying continued operation.

While the information system owner is responsible for resolving issues, simply resolving them "as quickly as possible" without an explicit decision from the AO, especially given high risk and low tolerance, is insufficient and doesn't address the immediate authorization status.

The security control assessor's role is to assess and report, not to implement controls; implementation is the responsibility of system developers or administrators.

The CISO's role involves overseeing security, but scoping and tailoring controls are typically done during the initial control selection and implementation phases, not as a primary response to numerous high-risk findings after an assessment, especially when the organization has low risk tolerance.
