If you want to check for vulnerabilities in an inherited App Engine application, which service should you use?

To check for vulnerabilities in an inherited App Engine application, the appropriate service to use is Cloud Security Scanner. This tool is specifically designed to identify security vulnerabilities in applications hosted on Google Cloud, including those running on App Engine. It performs an automated scan to detect common vulnerabilities such as cross-site scripting (XSS), insecure JavaScript libraries, and other potential security flaws that could be exploited by attackers.

Cloud Security Scanner not only helps in maintaining the security posture of your application by identifying vulnerabilities but also supports compliance with security best practices. This is particularly crucial for inherited applications, where the original development context may not align with current security standards or practices.

In contrast, while the other services mentioned—like Cloud Armor, Stackdriver Debugger, and Stackdriver Error Reporting—offer valuable functionalities, they have different focuses. Cloud Armor is primarily a security service that provides defense against distributed denial-of-service (DDoS) attacks and does not directly scan for application-level vulnerabilities. Stackdriver Debugger is used for examining the state of a running application and troubleshooting issues, while Stackdriver Error Reporting focuses on collecting and analyzing application errors to help developers fix them. None of these tools specifically target the identification of security vulnerabilities within the application codebase, which is why Cloud Security
