Description |
---|
Advertisement of routes by an autonomous system for networks that do not belong to any of its trusted peers pulls traffic away from the authorized network. This causes DoS on the network that allocated the block of addresses and may cause DoS on the network that is inadvertently advertising it as the originator. It is also possible that a misconfigured or compromised router within the network could re-distribute IGP routes into BGP thereby leaking internal routes. |

Review the router configuration and compare it against the network documentation (topology diagrams and peering agreements). Verify that each BGP peering session is configured with the correct IP address and remote Autonomous System Number (ASN). If any BGP peering session is not configured with the correct IP address and remote ASN, this is a finding. |

Configure each BGP peering session to the specific IP address of the peer router and remote ASN assigned to the organization controlling that peer. |
