A Firewall for Routers: Protect Again Routing Misbehavior
Overview This paper presents the novel idea of route normalization by correcting on the fly routing traffic on behalf of a local router to protect the local network from malicious and misconfigured routing updates. Analogous to traffic normalization for network instruction detection systems, the proposed RouteNormalizer patches ambiguities and eliminates semantically incorrect routing updates to protect against routing protocol attacks. Further more, it serves the purpose of a router firewall by identifying resource based attacks against routers. Upon detecting anomalous routing changes, it suggests local routing policy modifications to improve route selection decisions. Deploying RouteNormalizer requires modifications to routers if desired using a transparent TCP proxy setup.
