Basic Concept of Penetration Testing

The technique of simulating an assault on an organization’s IT infrastructure to find possible vulnerabilities is known as penetration testing, commonly referred to as pen testing. It entails a comprehensive assessment of the security of a network, system, or application to ascertain its resilience to an attack.

Penetration testing is used to find security flaws that might be used by hackers to access confidential data without authorization or to sabotage vital corporate activities. Organizations may better identify the risks they face and manage them by using the testing process to develop preventative measures.

Network penetration testing, online application penetration testing, and wireless network penetration testing are just a few of the several forms of penetration testing. Network penetration testing is assessing a network’s security to find openings that might be used to obtain unwanted access. Penetration testing for online apps is assessing their security to find openings that might be used to modify data or obtain unauthorized access. To find security flaws that may be used to obtain unauthorized access, wireless networks must first undergo penetration testing.

Planning and reconnaissance, scanning, obtaining access, keeping access, and concealing tracks are some of the processes of a penetration test. The penetration tester acquires data about the target network, system, or application during the planning and reconnaissance phase. The penetration tester searches for vulnerabilities using tools during the scanning phase. The penetration tester tries to use the discovered vulnerabilities to obtain unauthorized access during the gaining access phase. The penetration tester tries to keep access to the system or network open for as long as feasible during the maintaining access phase. The penetration tester tries to hide their tracks in the last step, concealing tracks, to prevent being discovered.
