The Dell OS10 BGP router must be configured to use a unique key for each autonomous system (AS) that it peers with.
If the same keys are used between eBGP neighbors, the chance of a hacker compromising any of the BGP sessions increases. It is possible that a malicious user exists in one autonomous system who wou...Rule Medium Severity -

The Dell OS10 Router must be configured to protect against or limit the effects of denial-of-service (DoS) attacks by employing control plane protection.
The Route Processor (RP) is critical to all network operations because it is the component used to build all forwarding paths for the data plane via control plane processes. It is also instrumental...Rule Medium Severity -

The Dell OS10 Router must be configured to have Internet Control Message Protocol (ICMP) unreachable notifications disabled on all external interfaces.
The ICMP supports IP traffic by relaying information about paths, routes, and network conditions. Routers automatically send ICMP messages under a wide variety of conditions. Host unreachable ICMP ...Rule Medium Severity -

The Dell OS10 BGP router must be configured to use the maximum prefixes feature to protect against route table flooding and prefix deaggregation attacks.
The effects of prefix deaggregation can degrade router performance due to the size of routing tables and also result in black-holing legitimate traffic. Initiated by an attacker or a misconfigured ...Rule Medium Severity -

The Dell OS10 BGP router must be configured to limit the prefix size on any inbound route advertisement to /24 or the least significant prefixes issued to the customer.
The effects of prefix deaggregation can degrade router performance due to the size of routing tables and also result in black-holing legitimate traffic. Initiated by an attacker or a misconfigured ...Rule Low Severity -

The Dell OS10 BGP router must be configured to use its loopback address as the source address for iBGP peering sessions.
Using a loopback address as the source address offers a multitude of uses for security, access, management, and scalability of the BGP routers. It is easier to construct appropriate ingress filters...Rule Low Severity -
