A white-box vulnerability assessment is a test conducted with complete knowledge and understanding of the infrastructure, defense mechanisms, and communication channels of the target on which the test is being conducted. This test is specifically intended to simulate insider attacks which are usually performed with full privileges and complete access to the target system. In order to initiate a white-box vulnerability assessment, the target organization shares all details, such as asset inventory, network topology diagrams, and so on, with the VA tester.
