Penetration Testing Basics
Penetration testing, also known as pentesting, is a security testing method used to evaluate the security of a computer system, network, or web application by simulating an attack on the system to identify vulnerabilities that can be exploited by an attacker.
The primary objective of a pentest is to identify vulnerabilities and weaknesses in a system before an attacker does, so that they can be fixed before they are exploited. Pentesters use a variety of tools and techniques to identify vulnerabilities, including manual testing, automated scanning, and social engineering.
Pentesting can be divided into two main types:
External Pentesting: Involves testing from outside the organization's network, usually over the internet.
Internal Pentesting: Involves testing from within the organization's network, typically behind the firewall.
Pentesting is an important component of an overall security strategy, and it can help organizations identify and address weaknesses in their security posture. However, it's important to note that pentesting should only be conducted by trained and experienced professionals, as it involves potentially risky activities that can cause damage or disruption to systems if not done properly.
