penetration testing

In a simple definition, penetration testing, penetration testing or pen testing is a simulated cyber attack against your computer system. This is a simulated attack to check exploitable vulnerabilities. Penetration testing is actually an attempt to assess the security level of IT infrastructure by testing and implementing existing vulnerabilities in a secure manner.
These vulnerabilities may occur at the level of operating systems, services, applications, end-user behaviors, settings, and configurations. Such evaluations, in addition to fulfilling their main goals, are able to confirm or reject defense mechanisms and also determine the end user's adherence to your security policies.
