A Firewall for Routers: Protect Again Routing Misbehavior

Tags:
switching

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.

VoIP primer: How it works - and what the jargon means

An IP packet is formed when a router chops up a stream of digital information into manageable chunks. The router then places two addresses in the packet's header field - one for the destination, one for the originating device.
