Abstract
Disclosed herein are filtering systems and methods that employ an electronic message source reputation system. The source reputation system maintains a pool of source Internet Protocol (IP) address information, in the form of a Real-Time Threat Identification Network (“RTIN”) database, which can provide the reputation of source IP addresses, which can be used by customers for filtering network traffic. The source reputation system provides for multiple avenues of access to the source reputation information. Examples of such avenues can include Domain Name Server (DNS)-type queries, servicing routers with router-table data, or other avenues.

18. An engine for providing source information for real-time filtering of incoming electronic messages, the engine comprising:
-
a server configured to receive a query from a subscriber for reputation data associated with a source requesting a TCP connection with the subscriber'"'"'s computer network; a controller configured to retrieve reputation data associated with the source; and wherein the server is further configured to provide the reputation data associated with the source to the subscriber substantially as the source is requesting the TCP connection, wherein the provided reputation data determines whether the subscriber'"'"'s computer network allows the TCP connection. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
