Routing Attacks

Geoff Huston one of the foremost authorities on Internet routing and scaling issues talks about 'Routing attack' and more.

 

However, for those of us unclear about the implication of a 'routing attack', here are a few pointers:

 

  • Routing attacks can "hijack" addresses, redirecting users' traffic to other than the intended destination, allowing an attacker to "spoof" the identity of the intended victim.
  • Routing attacks also can redirect traffic flows, allowing an attacker to inspect transit traffic without the knowledge of either end party.
  • In addition, routing attacks can disrupt the network, causing chaos and disruption, directed either at a single victim, or more generally at a collection of addresses or at infrastructure elements such as DNS servers.
