Penetration testing is the process of simulating a cyber attack. During this process, the testers deliberately send hard-to-detect inputs to the system under test. This may cause it to crash or slow down. By following the steps, penetration testers can detect vulnerabilities that other security professionals might overlook. But how does a penetration tester do it? How can an example help? Let’s discuss some of the most common ways that attackers exploit the system under test.

When it comes to obtaining higher access levels, there are many ways in which hackers can compromise a network. One of the most common is tailgating. This attack involves having an authorized user open a door for an unauthorized person. This attack rarely fails because the attacker is generally more sophisticated than asking for the door to be opened. This method is also known as “soft” attack. This method can be applied to many different types of networks, such as those of a company.

The purpose of penetration testing is to try to gain access to systems, as if you were an outsider. The attacker has limited knowledge about the target and works off assumptions. In an external attack, the attackers exploit the network perimeter from outside the organization, often from the Internet or Extranet. Insider attacks mimic the actions of a malicious insider, such as an employee with access to sensitive information. When the attackers gain access to the network, they attempt to use those credentials to exploit the system.

A penetration test is a stress test of the IT infrastructure, which is conducted by a trained pen tester. A penetration test uses various penetration techniques to try to break into a network and extract sensitive information. Pentesting can be used for new information systems before authorization, or for operational systems as part of regular security testing. Pentests are especially useful if there are major changes to the operating environment of the system or the set of possible threats.

Penetration tests are timed and usually require a fixed amount of time. Although a software may pass all tests, the absence of a vulnerability does not mean it is secure. A penetration tester can’t guarantee that they’ve covered all possible tests, and therefore must prioritize the tests that are most important first. They should be able to perform the necessary tests in a given amount of time. And a penetration test must also be performed in a timely fashion, because the attacker may exploit a system with a single exploit.

Pentesting can be divided into two types, known as black box or white box. Black box penetration refers to testing that uses a black-box approach. Black box penetration tests are similar to white-box tests in that they mimic the attacker’s experience, but the tester is given very little information about the system. A white-box penetration is a white-box test and is the most expensive. It takes a lot of time and effort to perform a black-box penetration test.
