What does the CIA triad consist of, and why is it relevant to private security?

• A. Compliance, risk, audit
• B. Confidentiality, integrity, and availability; it guides protection of information assets
• C. Classification, indexing, and archiving
• D. Access, authentication, and authorization

Answer: (B)

The CIA triad consists of Confidentiality, Integrity, and Availability—three fundamental goals of information security. Confidentiality means keeping information secret from unauthorized people or systems, achieved through access controls, authentication, and encryption. Integrity ensures data and systems remain accurate and unaltered, protected by measures like hashing, digital signatures, and strict change controls. Availability guarantees that information and critical services are accessible when needed, supported by reliable infrastructure, backups, redundancy, and disaster recovery planning. In private security, this framework guides how to protect information assets. It helps you prioritize controls, assess risks, and design policies that balance protection with operational needs. For example, a private company must keep customer data confidential, ensure transaction records are trustworthy, and maintain system uptime for customers to access services. The triad provides a common way to evaluate security measures and communicate requirements to stakeholders, which is why it’s the correct choice.
