The network device must not be configured to have any feature enabled that calls home to the vendor.

Call-home services will routinely send data such as configuration and diagnostic information to the vendor for routine or emergency analysis and troubleshooting. There is a risk that transmission of sensitive data sent to unauthorized persons could result in data loss or downtime due to an attack. (See SRG-NET-000131-RTR-000083.)

Review the device configuration to determine if the call home service or feature is disabled on the device.

If the call home service is enabled on the device, this is a finding.

Note: This feature can be enabled if the communication is only to a server residing in the local area network or enclave.
