[IP]; Interview the IAO and validate compliance with the following requirement: Ensure all protocols and services that cross the enclave boundary and/or any of the defined DoD boundaries (along with their associated IP ports) used by VTC systems for which he/she is responsible are registered in the DoD Ports and Protocols Database in accordance with DoDI 8550.1. Review network diagrams, device documentation, to identify what VTC/VTU/MCU Ports/Protocols/Services are used by the VTC system. Once these Ports/Protocols/Services have been determined and confirmed for use, verify that these same Ports/Protocols/Services are registered and approved for use in the DoD Ports and Protocols Database in accordance with DoDI 8550.1.
