Abstract

An automated network access protection system providing an efficient method for creating a list of disallowed network connection points. This is done by collecting network addresses connected to by users who have accessed the network in an unauthorized manner. This list of addresses is filtered to eliminate addresses which have been connected to by users not known to be unauthorized. Once this filtering has been completed, the list contains network addresses or phone numbers connected to only by unauthorized users. This list may further be filtered by removing any network addresses which appear in a separate list of globally valid addresses. This list may also be filtered to eliminate network addresses which are owned by commercial entities. Finally, custom filters may be applied to this list. After this filtering, this list is transferred to a mechanism for preventing connection to or from any of the network addresses or phone numbers contained in the disallowed list. The disallowed list may also be used to identify unauthorized network access attempts. By recognizing that a user is attempting to connect to or from a network address or phone number contained in the disallowed list, the network operator can reasonably presume that the attempt was unauthorized.
