Penetration testing (also called PenTesting) is the practice of testing a computer system, network or Web application to find vulnerabilities that an attacker could exploit.

Pen tests can be automated with software applications or they can be performed manually. Either way, the process includes gathering information about the target before the test (reconnaissance), identifying possible entry points, attempting to break in (either virtually or for real) and reporting back the findings.

The main objective of penetration testing is to determine security weaknesses. A pen test can also be used to test an organization's security policy compliance, its employees' security awareness and the organization's ability to identify and respond to security incidents.

Linux Server is an ideal first, secured and powerful server for any corporation. Linux Server is secured from virus so this is secure to store, organize, and access business information from virtually anywhere.

But here is problem about Linux Server! Every day hackers found new vulnerability and exploition to hack, resulted in the theft of millions of credit cards, major financial and reputational damage for hundreds of enterprises and even the more valuable information and database.
