Detailed explanation-1: -Application security testing (AST) is the process of making applications more resistant to security threats, by identifying security weaknesses and vulnerabilities in source code.

Detailed explanation-2: -A penetration test, also known as a pen test, is a simulated cyber attack against your computer system to check for exploitable vulnerabilities. In the context of web application security, penetration testing is commonly used to augment a web application firewall (WAF).

Detailed explanation-3: -A penetration test, or pen test, is an attempt to evaluate the security of an IT infrastructure by safely trying to exploit vulnerabilities. These vulnerabilities may exist in operating systems, services and application flaws, improper configurations or risky end-user behavior.

Detailed explanation-4: -Penetration Testing (Ethical Hacking) It can help evaluate how existing security measures will measure up in a real attack. Most importantly, penetration testing can find unknown vulnerabilities, including zero-day threats and business logic vulnerabilities.
