Besides the System Owner (SO), what role has the PRIMARY responsibility for implementing the security controls in the security and privacy plans for an Information Systems (IS)? Response:

A Common Control Provider (CPP) is specifically tasked with developing, implementing, assessing, and monitoring security controls that are provided to and inherited by other information systems, thereby fulfilling a primary implementation role for those shared controls.

A System Administrator typically focuses on the operational implementation and maintenance of controls for specific systems, rather than having primary responsibility for common controls across an enterprise.

An Information Owner (IO) is responsible for the data's classification and protection requirements but does not primarily implement system-level security controls.

An Information System Security Officer (ISSO) advises on and monitors the security posture of an IS, but their role is not primarily the implementation of security controls.
