Ultimate Guide to Becoming A Penetration Tester

Information security has become an increasing priority for businesses, governments and individuals in today’s digital environment. Faced with growing cybersecurity threats, organizations have invested significantly in security testing efforts to ensure their networks remain protected – prompting an upsurge in demand for experienced penetration testers, commonly known as pen testers.

Penetration testing involves simulating a cyber attack to discover vulnerabilities in an organization’s networks, systems, and applications. Penetration testers – sometimes referred to as ethical hackers – use various tools and techniques to detect weaknesses within its security infrastructure and take measures to address them.

If you are seeking to pursue a career in penetration testing, this guide provides all of the essential information.

What Is Penetration Testing (PT)?

Penetration testing is a method used to assess the security of an organization’s network, systems and applications. It involves simulating an attack against their infrastructure to identify vulnerabilities which could be exploited by malicious actors and exploited for exploit. Penetration testing forms an integral part of any comprehensive security testing strategy and organizations frequently conduct these tests in order to detect security weaknesses before they become exploitable.

What Is Metasploit? 

Metasploit is an open-source penetration testing framework used by security professionals to exploit vulnerabilities in networks, systems and applications. As one of the most widely-used penetration testing tools available today, Metasploit allows security professionals to more easily test for and exploit vulnerabilities within controlled environments.
