The document discusses vulnerability assessment and penetration testing (VAPT). It defines vulnerability assessment as systematically finding security issues in a network or system through scanning, and penetration testing as exploiting vulnerabilities to prove they can cause damage. The document outlines the types of VAPT testing, steps in the process, common tools used like Nmap and ZAP, and top vulnerabilities like SQL injection and XSS. It provides examples of specific vulnerabilities found like outdated themes and XML-RPC access, and their potential impacts and solutions.
