Which control should an organization implement to ensure that the software is written securely and...

Control 8.28, Secure coding, is the correct control because the question focuses on software being written securely and reducing potential vulnerabilities in the code. Secure coding addresses the practices, rules, and techniques developers should use to avoid common software weaknesses. This can include input validation, output encoding, error handling, authentication handling, secure session management, memory safety, protection against injection, secure API use, cryptographic correctness, dependency management, and code review. Control 8.29, Security testing in development and acceptance, verifies whether security requirements and controls are effective, but testing occurs after or during development and does not itself define how code should be written. Control 8.26, Application security requirements, defines security requirements for applications, but secure coding is the specific implementation practice that reduces vulnerabilities during software construction. ISO/IEC 27002 treats secure development as a lifecycle discipline: requirements define what is needed, secure coding implements it safely, and testing validates it. The direct match to the exam wording is Control 8.28.
