Penetration Testing

Security Testing 🔍 Difficulty: premium

Definition

Penetration testing is the practice of simulating real-world attacks on systems or networks to identify and fix security vulnerabilities before malicious actors exploit them.

Examples

  • A company hires a security firm to test whether its web application is vulnerable to SQL injection.
  • An internal red team conducts a simulated phishing attack to evaluate employee awareness and response.

Overview

Penetration testing, often referred to as a pen test, is a controlled security assessment that mimics the behavior of real attackers. Its purpose is to evaluate the effectiveness of security controls by identifying vulnerabilities in systems, applications, and human behavior before they can be exploited by malicious actors.

Pen tests are typically conducted by ethical hackers who use the same tools and techniques as actual attackers but in a safe, authorized, and structured manner. These tests help organizations understand their risk exposure and improve their overall security posture by fixing discovered issues.
