Which action enhances cloud security application deployment through standards such as ISO/IEC 27034 for the development, acquisition, and configuration of software systems?

Applying the steps of a cloud software development life cycle is crucial for enhancing cloud security in application deployment when adhering to standards like ISO/IEC 27034. This standard emphasizes a systematic approach to integrating security measures throughout the lifecycle of software development, which includes planning, development, testing, deployment, and maintenance.

By following a structured software development life cycle, organizations can ensure that security considerations are incorporated at each phase. This means conducting thorough risk assessments during the planning stage, embedding security controls in the design and coding practices, performing regular security testing, and establishing protocols for secure deployment and maintenance. This thorough process helps identify and mitigate potential vulnerabilities before they can be exploited, ensuring that security is not an afterthought but a fundamental component of the application environment from the outset.

Other options, while having merit, do not directly address the comprehensive integration of security throughout the entire software development lifecycle as effectively as applying a structured development life cycle does. They may support security in specific areas but lack the holistic approach needed to comply with robust standards like ISO/IEC 27034.
