The abbreviation ISSM stands for which role?

• A. Information System Security Manager
• B. Information System Security Master
• C. Industrial System Security Manager
• D. Information Security System Manager

Answer: (A)

Information System Security Manager is the standard title for the role responsible for the security of an information system. The phrase “Information System” denotes the system being protected, while “Security Manager” indicates the person who leads the security controls, risk management, and compliance activities. This pairing is commonly used in security frameworks (like NIST RMF) for the individual who oversees security planning, assessment, authorization, and continuous monitoring. The other options use nonstandard wording or refer to a different domain: for example, swapping the order as in “Information Security System Manager” is not the typical convention, using “Master” instead of “Manager” isn’t standard, and “Industrial System Security Manager” targets industrial/control systems rather than general information systems.
