The Dell OS10 Router must be configured to implement message authentication for all control plane protocols.
An XCCDF Rule
Description
A rogue router could send a fictitious routing update to convince a site's perimeter router to send traffic to an incorrect or even a rogue destination. This diverted traffic could be analyzed to learn confidential information about the site's network or used to disrupt the network's ability to communicate with other networks. This is known as a "traffic attraction attack" and is prevented by configuring neighbor router authentication for routing updates. This requirement applies to all IPv4 and IPv6 protocols that are used to exchange routing or packet forwarding information. This includes BGP, RIP, OSPF, EIGRP, IS-IS, and LDP.
