What Is a Penetration Tester and How Do You Become One?
A penetration tester, also known as a “pentester” or “ethical hacker”, is a security professional who tests computer systems, networks, and applications to find and exploit security vulnerabilities.
In order to become a penetration tester, a strong understanding of computer networking, systems administration, programming, and security concepts is essential. You should also have experience with various operating systems, networking protocols, and security tools.
You should be familiar with the fundamentals of ethical hacking, such as understanding the differences between an attack and a vulnerability scan, and how to use Windows, Linux, and Mac OS X operating systems. In addition, knowledge of web application security, cryptography, and system hardening techniques is also beneficial.
Having certifications such as Certified Ethical Hacker (CEH) and Offensive Security Certified Professional (OSCP) are also beneficial for a prospective penetration tester. These certifications will provide additional knowledge and help demonstrate your ability to potential employers.
In addition to the technical skills, a successful penetration tester must also possess strong analytical and problem-solving skills, as well as a passion for security. They should also be able to communicate effectively with clients, and have an understanding of legal and ethical issues related to security testing.
Becoming a penetration tester can be a challenging and rewarding career path. With the right skills and qualifications, you can start your career in the field of information security by testing computer systems and networks for vulnerabilities.
