Evaluation of Operating System :
1. Obtain or prepare logical and physical diagrams of the operating system and attached local and wide area networks.
2. Document the operating system domain(s), identifying the Primary Domain Controller (PDC), Backup Domain Controller, and any other operating
system servers or significant operating system workstations participating in the domain.
3. Using the information obtained in the prior steps, document the server and directory location of the significant application programs and data within the network; document the flow of transactions between systems and nodes in the network.
4. Using the Server Manager Utility, review all trusted domains assigned to the audit domain and include these trusted domains within the audit scope.
5. Assess whether the trusted domains are under the same physical and administrative control and are logically located within the same subnetwork.
6. Determine that router filtering is being used to prevent external network nodes from spoofing the IP address of a trusted domain.
