If an organization provides network architecture and/or services information to a third-party for testing on specific operations, what type of test would this be?

The correct answer is white box testing. In white box testing, testers have complete knowledge of the system architecture and its internal workings. This type of testing allows for a comprehensive evaluation of security vulnerabilities, as it involves access to source code and architecture information. By providing network architecture and services information to the third-party testers, the organization is essentially allowing them to understand the system thoroughly, which is a hallmark of white box testing.

This approach enables the testers to design tests that take advantage of their understanding of how the system operates, thereby potentially uncovering issues that could be missed in more opaque testing methods. White box testing is valuable for ensuring that security measures are effective and for assessing the application’s coding practices.
