What process is characterized by ongoing evaluation of web application security?

The process characterized by ongoing evaluation of web application security is dynamic analysis. This method involves testing a web application while it is running to identify security vulnerabilities that may be exploited in real time. Unlike static application security testing, which analyzes code without execution, dynamic analysis focuses on the application's behavior in its operational environment, allowing for the detection of issues that can only be seen when the application is active.

Dynamic analysis is essential for continuous security assessments because web applications often change over time, whether due to new features being added, updates, or the evolving nature of threats. This approach helps ensure that vulnerabilities are assessed continually throughout the development and deployment lifecycle, allowing organizations to respond to security challenges promptly and effectively.

In contrast, static application security testing and application vetting typically involve examination phases that do not occur continually during the application’s runtime, and secure design patterns focus more on the architectural frameworks rather than the ongoing evaluation of security. Thus, dynamic analysis stands out as the correct answer for ongoing security evaluation.
