Steps involved in Penetration Testing

Penetration testing, commonly known as pen testing, is a simulated attack on a network system or application to identify vulnerabilities that hackers could exploit. As a penetration tester, understanding the steps involved in a pen test is essential in ensuring a successful test.

Planning and reconnaissance – The first step in penetration testing involves gathering information about the system to be tested. This involves identifying the targets, the scope of the test, and the available attack surfaces.
Scanning – In this step, a pen tester uses various tools to identify open ports, services, and vulnerabilities present in the system.
Gaining Access – Once the vulnerabilities have been identified, the tester attempts to exploit them to gain access to the system.
Maintaining Access – After getting access, the tester tries to maintain access by installing backdoors to gain persistent access to the system.
Analysis and reporting – The final step involves analyzing the results and producing a report that outlines the vulnerabilities found, the potential impact of these vulnerabilities, and recommendations for securing the system.

What happens during a Penetration Testing

During penetration testing, a simulated attack is conducted on a system to identify vulnerabilities that could be exploited by hackers. The testing can either be done internally, where the tester has access to the system, or externally, where the tester does not have any prior knowledge of the system.

The pen tester tries to exploit the identified vulnerabilities to gain access to the system, compromising data or causing disruption that could impact the organization negatively. The testing can be performed using various methods, including black-box, gray-box, and white-box testing.

Different testing methods

Black-box testing

Black-box testing is done externally, where the pen tester has no prior knowledge of the system. The tester tries to discover and exploit the vulnerabilities by observing how the system responds to different attacks.

Gray-box testing

Gray-box testing involves the pen tester having some knowledge of the system, such as being an authenticated user. The tester then attempts to discover vulnerabilities and exploit them, simulating an insider threat.

White-box testing
