The main differences between black box, white box, and gray box penetration testing are:
- Knowledge of the target system: Black box testing involves no knowledge or information about the target system, white box testing involves full knowledge and access to the internal details and workings of the target system, and gray box testing involves limited knowledge and access to the target system.
- Perspective of the tester: Black box testing simulates the perspective of an external attacker, white box testing simulates the perspective of an insider or developer, and gray box testing simulates the perspective of a user or customer with limited access to the system.
- Tools and techniques used: Black box testing typically involves using tools and techniques that are commonly used by external attackers, white box testing typically involves using tools and techniques that are commonly used by insiders or developers, and gray box testing typically involves using tools and techniques that are commonly used by users or customers.
Overall, the main differences between black box, white box, and gray box penetration testing are the knowledge of the target system, the perspective of the tester, and the tools and techniques used. These differences can affect the scope, objectives, and results of the penetration test, and can help organizations choose the most appropriate type of testing for their needs and requirements.
