Organizations are not protecting their BGP session. Take the time to ask the question …. Do we have our BGP ports protected? Are you: If not, work with your peers to deploy an Infrastructure ACL (iACL) to cover all your network devices, deploy specific data plane ACLs on your routers/switches to protect them, work with

BGP Security Workshop – Safeguarding the Internet’s Glue
BGP and DNS are the two critical protocols that glue the entire global network (the Internet). Without them, the Internet falls apart. The security, resiliency, and integrity Border Gateway Protocol (BGP) holds up the routing of packets end-to-end across the Internet. Threats to BGP systems are life-threatening, disrupting critical infrastructure people depend on for their
Recommendation: BGP Ingress & Egress Filtering BCPs
The core BGP Security recommendation is for all BGP Ingress & Egress Filtering to follow BCPs. These BGP Best Common Practices (BCPs) are not confidential. Your peers would be open to share what they do and help you deploy better policies. It is recommended that you inspect your network’s practices and procedures. Review the BCP
Principle: BGP Hijacking Risk Reduction is a Layered Solution
Reducing the BGP Hijacking risk reduction is a layered solution. Organizations cannot jump into RPKI BGP Security if they have not established the basics for BGP Security. It must be remembered that projecting against BGP Hijacks is not a “one tool” approach. All the BGP Security techniques work together. Organizations should view this as
Recommendation: Use Internet Route Registries (IRR)
Use Internet Route Registries (IRR) to register all BGP sessions to your ASN, require all your peers to use the same IRRs, and then script the configurations to update the ingress/egress prefix filtering. It does not make any sense to have all the BGP sessions undocumented. Internet Route Registries (IRRs) and tools like PeeringDB document how
Recommendation: Deploy Peerlock
Operators deploying Peerlock mitigate many route leak and BGP Hijacking risks. Peer-Lock is an optimized AS-Path Filtering technique. The foundation is not new. We have been using AS Path Filtering for decades. The new approach uses the AS-Path filter and a written peering agreement. Job Snijders pioneered and championed Peerlock while @ NTT (see NTT Peer
Recommendation: Grasp the risk from BGP Hijacking
It is really important that ever organization grasp the risk from BGP Hijacking. The CIO, CISO, Security Professional, Network Engineers, and all others in the organization must understand that the BGP Hijacking Threat to their organization is Real. Miscreants have BGP hijacked critical resources away from the owning organization and caused damage. These BGP Hijacks
Recommendation: All prefixes will have one BGP Community
We have learned in the community that it is safer to have all prefixes with one BGP Community. That means a BGP community will be required for the route to get advertised to a peer. Granted, each prefix might have multiple BGP Communities, but the requirement that each must have at least one BGP community
Recommendation: Use Maximum Prefix Filters on all BGP Sessions
Maximum Prefix Filters are often overlooked in BGP configurations. Don’t overlook BGP Maximum Prefix Filters. They can save your network in a route table explosion crisis. Why? Exploding BGP tables is one of the huge risks to Internet stability. We have had and will have routers which de-aggregate, rapidly increasing the size of the BGP RIB
Tools for BGP Peering, Analysis, Troubleshooting & Monitoring
Tools to troubleshoot routing issues, monitor for BGP Hijacking, and alert when there are major routing issues are critical for any organization who connects to the Internet. This is a guide to help organizations pick tools that are useful. BGP Stream by BGPMON BGP Stream is a free resource for receiving alerts about hijacks,
