| Description | ||||
| MSDP peering with customer network routers presents additional risks to the Defense Information Systems Network (DISN) core, whether from a rogue or misconfigured MSDP-enabled router. MSDP password authentication is used to validate each segment sent on the Transmission Control Protocol (TCP) connection between MSDP peers, protecting the MSDP session against the threat of spoofed packets being injected into the TCP connection stream. | ||||

Auth Status : Enabled
If the router does not require MSDP authentication, this is a finding.
