The penetration model that would likely provide a network diagram showing all the company's routers, switches, firewalls, and intrusion detection systems, or give the tester a floor plan detailing the location of computer systems and the operating systems running on these systems, is the white box model.
In a white box penetration test, the tester is given extensive information about the system and network architecture, including network diagrams, source code, and other documentation. This access allows for a more comprehensive assessment of security vulnerabilities compared to the other models, where less information is provided.
