Who amongst the following makes the final accreditation decision?

An Information System Security Engineer (ISSE) designs, develops, and implements security solutions for information systems, but does not make accreditation decisions.

A Chief Risk Officer (CRO) is typically responsible for overseeing an organization's overall risk management strategy, but the DAA holds the specific authority for system accreditation decisions.

The Designated Approving Authority (DAA) is the senior management official who formally accepts the risk of operating an information system and makes the final decision on whether to accredit it for production use. The DAA weighs the security posture against mission requirements and organizational risk tolerance.

An Information System Security Officer (ISSO) is responsible for the day-to-day security posture and operations of an information system, working under the DAA's guidance but not making the final accreditation decision.
