What does Runtime Application Security Protection (RASP) primarily do?

Runtime Application Security Protection (RASP) primarily focuses on detecting and responding to security violations within an application while it is running in its actual environment. This technology is integrated into the application and can analyze the application's behavior in real-time, understanding its context and the nature of its runtime environment.

By operating in this manner, RASP enhances the application's security posture by being able to identify threats and vulnerabilities as they occur, rather than relying solely on static analysis methods or pre-deployment testing. It can automatically react to security incidents, potentially stopping attacks in progress or blocking malicious inputs, thus providing a dynamic layer of defense.

In the context of the other options, examining application logs for vulnerabilities is a more passive approach and does not involve real-time detection or active response. Managing application performance and updates pertains to the operational efficiency of an application, which is outside the purview of security. Monitoring user interactions with applications may involve assurance measures but does not primarily focus on detecting or mitigating security threats in real-time.
