Security testing and auditing are the methods of assessing and improving the security of web testing data. Security testing and auditing can identify and fix any vulnerabilities, risks, or flaws in your web testing data or the systems that handle it. You can use security testing and auditing tools to perform various types of security tests, such as penetration testing, vulnerability scanning, code review, or compliance audit, on your web testing data or the web applications that use it. For example, you can use security testing software to simulate attacks on your web testing data or the web applications that use it, or you can use security auditing software to monitor and report any security incidents or violations.
