BGP routing isn’t secure. It’s main hope, RPKI, uses a certificate system that’s akin to secure web browsing (or at-least it’s early days). While secure web browsing has moved on and is far more secure and is somewhat the default these days, the state of BGP route validation has not moved forward. To secure BGP routing, all networks would need to be embrace RPKI (and more). Cloudflare proposes to plot a course to improve BGP routing-security globally by setting an example and implementing best practices, installing operationally excellent software and promoting its RPKI effort worldwide. RPKI is one of our focuses in 2018 and beyond!
