STIGQter STIGQter: STIG Summary: Voice Video Services Policy Security Technical Implementation Guide Version: 3 Release: 17 Benchmark Date: 25 Oct 2019: The VVoIP system management network must provide bidirectional enclave boundary protection between the local management network and the DISN voice services management network.

Fix Recommendation

Implement and document the VVoIP system management network to provide bidirectional enclave boundary protection between the local management network and the DISN voice services management network.

Check Contents

Review site documentation to confirm the VVoIP system management network provides bidirectional enclave boundary protection between the local management network and the DISN voice services management network. This requirement is applicable to VVoIP core system devices and TDM based telecom switches managed via multiple networks and those managed via a single physical Ethernet IP interface. For example, when the ADIMSS and local SAs both manage a VVoIP system or device via a common pathway such as the local management VLAN or OOB management network, a firewall is required between the local network and the ADIMSS network.

Determine who owns and is responsible for the enclave boundary protection device configuration and management. This device may be owned and operated by the DISN management network or the local network. Two such devices may be owned and operated by each entity.

If the VVoIP system management network does not provide bidirectional enclave boundary protection between the local management network and the DISN voice services management network, this is a finding.
