Cybersecurity testing
Also written: Penetration testing, Pen testing, Ethical hacking
Testing computer systems by simulating attacks to find and fix security weaknesses before they can be exploited.
Cybersecurity testing is like hiring a security guard to try and break into your own building. The goal is to find weak spots, like unlocked doors or windows, before a real burglar does.
This process involves using the same tools and methods that hackers might use, but in a controlled way. The testers then report the weaknesses so they can be fixed, making the system more secure.
Cybersecurity testing, often referred to as penetration testing or ethical hacking, involves simulating cyberattacks against computer systems, networks, or applications to identify exploitable vulnerabilities. It aims to uncover security flaws that could be leveraged by malicious actors.
Methods include vulnerability scanning, social engineering, and exploiting known weaknesses. The output is a report detailing discovered vulnerabilities, their severity, and recommended remediation steps. Tradeoffs involve the cost and time of testing versus the potential cost of a breach.
AI models are increasingly capable of sophisticated actions, including simulating attacks. Recent reports highlight that AI can now be used to penetrate company systems, underscoring the growing importance of cybersecurity testing in the AI development lifecycle.

The concept of testing security by simulating attacks has roots in military strategy and early computer security research. Formalized penetration testing emerged as computing became more widespread and networked.
You can explore basic security concepts by trying to guess weak passwords on a test account. Many online platforms offer 'capture the flag' (CTF) challenges that simulate cybersecurity scenarios in a safe, educational environment.

Questions people ask
- What is the difference between cybersecurity testing and a security audit?
- A security audit checks if security policies and procedures are being followed, while cybersecurity testing actively tries to break into systems to find exploitable flaws.
- Is cybersecurity testing the same as hacking?
- Cybersecurity testing is ethical hacking performed with permission to improve security. Malicious hacking is illegal and intended to cause harm or steal information.
