Introduction Infrastructure protection best practices –List of what is being done today Expected beneficiaries are both operators and end customers Draft is mostly focused on traffic to the network rather than transit traffic Complements BCP 38/84

Edge Infrastructure ACLs Key for protecting the SP network from external attack traffic targeting the core infrastructure First line of defense – commonly deployed and very effective in practice Draft describes ACL composition and provides a guide to implementation

Edge Remarking Ensures QoS policy supports security posture Advise edge remarking for ingress traffic –Ex. Prec 6/7 should never be seen on transit traffic

Device Protection Allows for aggregate security policy implementation for control and management traffic sent to a device Used in addition to service specific security tools like VTY ACLs Draft describes policy composition and provides a guide to implementation

Infrastructure Hiding Advanced technique for protecting core resources by denying reachability –You can’t attack what you can’t target Draft covers multiple mechanisms –Use less IP –MPLS techniques –IGP configuration techniques –Route advertisement filtering and control

IP V6 This section discusses the applicability of the other sections to IPv6 Networks Network infrastructure is enabled with this today No new techniques

Multicast needs love too Often overlooked Multicast requires different techniques from unicast Covers techniques such as: –filtering protocol/data –Rate limiting
