What is the position Senior Information Security Officer, or Chief Information Security Officer, known as at the the agency level? Response:

The Chief Information Officer (CIO) is responsible for the overall IT strategy and management within an agency, which includes security but is broader than just information security leadership.

An Information System Security Officer (ISSO) is typically responsible for the security of specific information systems, not the entire agency-wide security program.

According to federal information security mandates and NIST guidelines, the Senior Agency Information Security Officer (SAISO) is the designated agency-level position responsible for the overall information security program and its implementation throughout the agency. This role typically carries the responsibilities of a CISO or Senior Information Security Officer at an enterprise level.

Senior Information System Security Officer is not the standardized federal designation for the agency-level chief security role; SAISO is the correct term.
