What is the goal of using regression testing in security?

The goal of using regression testing in security is primarily to ensure that new changes do not compromise existing security. Regression testing involves re-running previously completed tests on new code to verify that the changes have not introduced any new vulnerabilities or affected the security posture of the application.

When development teams implement updates, bug fixes, or new features, there is a risk that these modifications might inadvertently disrupt existing functionalities, including security mechanisms. By conducting regression tests focused on security aspects, organizations can identify and mitigate potential weaknesses introduced during the development process. This testing is crucial in maintaining the integrity and protective measures of the software application, thus safeguarding it against new threats while ensuring that previously resolved security issues remain addressed.

Other options such as improving user experience, speeding up software deployment, or enhancing system performance, while important in their own contexts, do not specifically address the primary aim of regression testing related to security. The focus on security testing highlights the ongoing need to protect sensitive data and ensure compliance with security standards as the software evolves.
