What is one method included in corrective controls for improving security?

The choice of upgrades and patches as a method included in corrective controls for improving security is particularly significant. Corrective controls are designed to address and rectify security incidents or vulnerabilities after they have been detected. When software is subject to vulnerabilities or bugs, applying upgrades and patches is one of the most effective ways to strengthen the security posture. These updates often contain critical fixes that mitigate risks, improve functionality, and enhance overall system integrity.

Upgrades and patches can resolve known vulnerabilities that cyber attackers might exploit, thereby preventing potential breaches or data loss. This proactive measure not only addresses immediate concerns but also ensures that the system remains resilient against evolving threats over time.

The other methods, while beneficial in various security contexts, do not directly fit within the traditional scope of corrective controls. Revised software architecture, for instance, may pertain more to preventive measures by improving the overall design and framework of the software to avoid future vulnerabilities rather than directly addressing existing ones. Secure facility enhancements relate more to the physical security environment, and enhanced data storage generally pertains to data management rather than directly mitigating specific security vulnerabilities.
