Difference Between Black Box, White Box, and Grey Box Pen Testing

📚 Quick Study Guide

• 🕵️‍♀️ Black Box Testing: Testers have no prior knowledge of the system. They simulate an external attacker.
• 👨‍💻 White Box Testing: Testers have full knowledge of the system, including source code, architecture, and configurations.
• ⚙️ Grey Box Testing: Testers have partial knowledge of the system. This is a mix of black box and white box approaches.
• 🎯 Goal of Pen Testing: Identify vulnerabilities that could be exploited by attackers.
• 🛡️ Benefits: Improved security posture, compliance with regulations, and reduced risk of data breaches.
