Abstract
A mechanism is provided for blocking IP connection addresses and prefixes. Header information is extracted from an incoming connection request. A determination is made as to whether a portion of an Internet Protocol address comprised in the header information is blacklisted. Responsive to a portion of the Internet Protocol address being blacklisted, a fingerprint is generated, and a determination is made as to whether the fingerprint is blacklisted. Responsive to the fingerprint being blacklisted, the underlying physical connection is dropped; data associated with the incoming connection request is stored in a buffer, the fingerprint is associated to the incoming connection request; the incoming connection request is merged with stored blacklisted requests of a related originating system; and shared prefixes of the Internet Protocol address of the stored blacklisted requests are filtered out.
