Penetration testing - GCSE Computer Science Definition

Penetration testing, often called "pen testing," is a way to check the security of a computer system, network, or software by pretending to be a hacker. It involves trying to find and fix weaknesses before real hackers can find them. Think of it like testing the doors and windows of a house to make sure they are locked and secure. By simulating cyber attacks in a safe and controlled way, pen testing helps keep personal data and information safe from cyber criminals. This is an important part of cybersecurity, which is about protecting computers and data from being accessed without permission.
