What acronym represents the discipline protecting confidentiality, integrity, and availability of information systems, commonly abbreviated as INFOSEC?

• A. Emsec
• B. OPSEC
• C. Information Security (INFOsec)
• D. Computer Security (Compusec)

Answer: (C)

The key idea here is the field that guards information assets by protecting confidentiality, integrity, and availability—the CIA triad. The broad discipline that covers policies, controls, and technologies to safeguard information and information systems is Information Security. Its standard shorthand is INFOSEC, which matches the familiar acronym used in military and security contexts. So, the best choice is Information Security (INFOsec) because it directly names the discipline and aligns with the common abbreviation INFOSEC. Other terms focus on narrower or different areas: Emsec (emission security) concentrates on preventing information leakage through emanations; OPSEC (operations security) targets safeguarding operational details; Computer Security is related but broader and not the canonical label for the information-protection discipline.
