What does ISSO stand for?

• A. Information System Security Officer
• B. Information Security Standards Office
• C. Information System Security Operations
• D. Information Systems Security Overseer

Answer: (A)

ISSO stands for Information System Security Officer. This role is the person responsible for leading the security of a specific information system, including implementing and maintaining security controls, developing and updating the System Security Plan, and coordinating risk management and continuous monitoring to ensure ongoing compliance. In many frameworks like RMF, the ISSO oversees day-to-day security activities for the system and acts as the main point of contact for security decisions and issues. The other terms don’t reflect the established title used in practice, so they aren’t correct representations of the acronym.
