The information security architecture at the individual information system level must be consistent with and complement the more global, organization-wide information security architecture that is integral to and developed as part of the enterprise architecture. The information security architecture includes an architectural description, the placement/allocation of security functionality (including security controls), security-related information for external interfaces, information being exchanged across the interfaces, and the protection mechanisms associated with each interface.
Review the Voice Video SSP for the system. Confirm the Voice Video system has approval for all commercial Voice Video connections by the DoDIN Waiver Panel, signed by DOD CIO for a permanent alternate connection to the ITSP. Voice Video system use cases applicable to this requirement: - Use Case 1: ITSP connections providing direct connection to the enclave's DoD LAN - Use Case 2: ITSP connections providing a SIP trunk terminating on a media gateway that provides TDM trunks or POTS lines to traditional non-VoIP PBX, key system, or individual end instrument - Use Case 3: ITSP connections terminating on a separate LAN from the enclave's DoD LAN supporting a separate VoIP system - Use Case 4: ITSP connections providing service over any approved ISP gateway If any enclave connects with a commercial VoIP provider (ITSP) and is not approved by the DoDIN Waiver Panel, this is a finding. If the DOD CIO has not signed for a permanent alternate connection to the ITSP, this is a finding. NOTE: This connection will be a permanent connection and should be designated or recognized as such in the approval documentation since most approvals of this type are for temporary connections.
Obtain and document in the Voice Video SSP the approval by the DoDIN Waiver Panel and signature by the DOD CIO for a permanent alternate connection to the ITSP for any connection with a commercial VoIP provider (ITSP).
