What is the primary purpose of a security control?

• A. To mitigate vulnerabilities and protect CIA
• B. To log all user activity
• C. To enforce password changes
• D. To encrypt all data automatically

Answer: (A)

Security controls exist to reduce risk by addressing vulnerabilities and protecting information assets, especially the Confidentiality, Integrity, and Availability (CIA) of data. That broad purpose—mitigating vulnerabilities and safeguarding CIA—is what a security control is designed to achieve. Logging user activity, for example, is a monitoring and auditing measure that helps detect and investigate incidents, not the overarching reason controls exist. Enforcing password changes targets authentication policy, which is important but narrower in scope. Encrypting data is a powerful protection mechanism, but applying encryption to all data automatically isn’t the universal, foundational reason controls are implemented; it’s one technique among many. So, the strongest concept here is that the primary function of a security control is to reduce risk by mitigating vulnerabilities and protecting the CIA triad.
