Is BGP safe yet? · Cloudflare

On the Internet, network devices exchange routes via a protocol called BGP (Border Gateway Protocol). Unfortunately, issues with BGP have led to malicious actors being able to hijack and misconfigure devices leading to security problems which have the potential to cause widespread problems. BGP security can be greatly improved by using technologies such as RPKI to sign Internet routes. This page attempts to track the progress of major Internet players (ISPs, transit operators, and content providers) in their progress to adopt RPKI and other technologies.

RPKI doesn't make BGP safe, it makes it safer. BGP hijacks can still happen.

RPKI only secures the ownership information of a given prefix, not the path to that prefix. Under RPKI, an attacker can still claim to be on the path to a victim AS, and get the victim's traffic sent to it.

The solution to this was supposed to be BGPSec, but it's widely seen as un-deployable.

RPKI makes prefix ownership verifiable, but the path is still largely trust-based.

It feels like we’ve secured the part that’s easiest to validate, not necessarily the part that matters most.
