Who is primarily responsible for the development of the system-specific procedures (ISO, ISSO, IS Architect, Sys Admin)? Response:

The Information Systems Security Officer (ISSO) is typically responsible for overseeing the information system's security posture, which includes the development and implementation of system-specific security procedures to ensure compliance with policies and regulatory requirements.

A System Owner has overall responsibility for the system, including its security, but delegates the detailed development of security procedures to security specialists like the ISSO.

A System Architect designs the system's structure and components, including security architecture, but usually does not develop detailed operational security procedures.

A System Administrator implements and operates the system according to established procedures but is not primarily responsible for developing those procedures.
