What are countermeasures?

• A. Actions taken to ensure application security.
• B. A type of data backup policy.
• C. Methods for resource scheduling.
• D. The design of user interfaces.

Answer: (A)

Countermeasures are safeguards and actions taken to reduce risks to information systems and protect applications from threats. In application security, they are the concrete steps you put in place to prevent breaches, detect issues, and recover quickly when problems occur. Examples include secure coding practices, input validation, strong authentication and access controls, encryption, patch management, secure configuration, logging and monitoring, and well-defined incident response plans. This makes the option describing actions taken to ensure application security the best fit, because it directly captures the purpose of countermeasures: the proactive measures you implement to protect the application. The other choices point to different domains. A data backup policy focuses on recovery after data loss, not the ongoing protective controls themselves. Methods for resource scheduling relate to how systems allocate compute resources, not security protections. The design of user interfaces concerns usability and user experience, not the safeguards that defend against threats.
