[IP]; Interview the IAO and validate compliance with the following requirement: If the VTU is connected to an IP based LAN, ensure remote management access (administrator and management system/server/application) and SNMP access and reporting is restricted by IP address and/or subnet. Determine what IP addresses or subnets are authorized to send VTC system/device “Remote Control/Management/Configuration” messages and what IP addresses or subnets are authorized to receive monitoring or status messages from the VTC system/device. Have the SA demonstrate how the VTC system/device is configured to restrict “Remote Control/Management/Configuration” messages to and from these authorized IP addresses or subnets. This is a finding if there is no limitation on either sending or receiving these messages. Note: During APL testing, this is a finding in the event the VTC system/devoice does not support the limiting of all management traffic to authorized IP addresses or subnets.
