Chapter 1. Python with Penetration Testing and Networking
Penetration (pen) tester and hacker are similar terms. The difference is that penetration testers work for an organization to prevent hacking attempts, while hackers hack for any purpose such as fame, selling vulnerability for money, or to exploit vulnerability for personal enmity.
Lots of well-trained hackers have got jobs in the information security field by hacking into a system and then informing the victim of the security bug(s) so that they might be fixed.
A hacker is called a penetration tester when they work for an organization or company to secure its system. A pentester performs hacking attempts to break the network after getting legal approval from the client and then presents a report of their findings. To become an expert in pentesting, a person should have deep knowledge of the concepts of their technology. In this chapter, we will cover the following topics:
