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

The action that enhances cloud security application deployment through standards such as ISO/IEC 27034 is applying the steps of a cloud software development life cycle. This standard emphasizes the importance of systematically managing the security aspects of software throughout its development, acquisition, and configuration phases. By following a structured development life cycle, organizations can ensure that security considerations are integrated into every phase of the software's life, from planning and design through to implementation and maintenance.

This approach not only helps in identifying and mitigating security risks early in the process but also aligns the development practices with recognized international standards, ensuring comprehensive coverage of security requirements. This systematic application fosters a culture of security awareness among developers, leading to better outcomes in the deployment of secure applications in the cloud.

In contrast, providing developer access to supporting components and services focuses on operational aspects rather than security throughout the development cycle. Outsourcing infrastructure and integration platform management may shift some responsibilities away from the organization, but it does not inherently enhance the security of the application development process itself. Verifying the application's confidentiality and integrity is crucial but occurs later and is not a proactive measure throughout the development life cycle.
