What is a White-Box-Pentest?

A White Box Penetration Test is a security test where the tester knows absolutely everything about the system they are supposed to check. They know the servers, operating systems, applications, and services. They even know which ports are open or should be open. With this knowledge, they can start right away and thoroughly examine the systems. This allows them to conduct a detailed target-actual comparison and specifically search for vulnerabilities.

How does a White Box Penetration Test work?

In this test, the penetration tester works closely with the company. You provide them with all the information they need: documentation, architecture plans, source codes – simply everything. The tester uses this insider knowledge to check the system for security vulnerabilities that an attacker with similar knowledge could exploit. While this makes the test time-consuming, it's also very effective.

What are the advantages of a White Box Penetration Test?

The White Box Test offers several clear advantages. Through the comprehensive insight, the tester can find vulnerabilities that might otherwise be overlooked. The advantages include:

1. Higher detection rate of security vulnerabilities
2. Faster approach in tests and simulations
3. Thorough network risk analyses
4. Consideration of new attack vectors from the developers' perspective

What are the disadvantages of a White Box Penetration Test?

Despite the advantages, there are also some challenges:

1. The amount of information can be overwhelming and time-consuming
2. It requires a systematic approach to avoid missing any vulnerabilities
3. Trust is important as sensitive information is shared
4. The White Box approach is significantly more expensive than a Black Box approach

When is a White Box Penetration Test useful?

A White Box Test makes particular sense when you want to conduct an in-depth security analysis that goes far beyond a Black Box Pentest. It is ideal for checking the security of critical systems or applications that contain particularly sensitive data. With a well-executed White Box Pentest, companies can effectively secure their IT infrastructure and proactively address vulnerabilities.

Conclusion

While the White Box Penetration Test is extensive, it's worth it. Through comprehensive knowledge of the system, vulnerabilities can be effectively found and fixed. Anyone who wants to thoroughly secure their IT infrastructure should consider this testing method.
