Abstract

A method for preventing denial of service attacks against Hypertext Transfer Protocol (HTTP) servers includes receiving a HTTP request from a subscriber using a first communication network coupled to at least one other communication network, receiving a profile for the subscriber, filtering the request to determine whether the subscriber is authorized to make the request based upon the profile and forwarding the request to the other communication network when the subscriber is authorized to make the request. An apparatus capable of preventing denial of service attacks against HTTP servers includes a profile request generator capable of generating a profile request based upon a HTTP request received from a subscriber using a first communication network, a filter capable of determining whether the request is authorized based upon the requested profile and an authorizer capable of allowing the request to be forwarded on at least one other communication network coupled to the first communication network.
