Abstract
An edge device is dynamically reconfigured to block undesired traffic using control information that originates in a core network. The control information is delivered to the device indirectly and, in particular, by a core appliance (e.g., an intrusion prevention system) setting and returning an HTTP cookie to a requesting client. The edge device is pre-configured to respond to HTTP cookies that have (or that are) control information. When the receiving client later returns that cookie to the edge device to obtain subsequent service, the control information that originated at the core is used by the device to deny that service. This indirect method of communicating the control information (from the core to the requesting client and then back to the device) enables the device to be reconfigured dynamically as needed to address network exploits or other threats.
