Electronic message source reputation information system
First Claim
1. A network traffic filtering system for filtering a flow of electronic messages across a computer network from electronic message sources to intended recipients, the system comprising:
- an engine configured to generate source reputation profiles of electronic message sources; and
a source reputation profile of a message source created by the engine and comprising;
a first reputation score for a message source calculated by the engine based on reputation data associated with the message source, the reputation data indicating a likelihood that electronic messages from the message source are unwanted by intended recipients of the messages, and a second reputation score for the message source adjusted from the first reputation score by the engine based on updated reputation data associated with the message source, the updated reputation data indicating a decreased likelihood that electronic messages from the message source are unwanted by the intended recipients.

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-Tine 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.

22. A method of filtering a flow of electronic messages across a computer network from electronic message sources to intended recipients, the system comprising:
-
calculating a first reputation score for a message source based on reputation data associated with the message source, the reputation data indicating a likelihood that electronic messages from the message source are unwanted by intended recipients of the messages;
blocking messages sent from the message source from reaching the intended recipients when at a first time when the first reputation score is attributed to the message source;
adjusting the first reputation score to a second reputation score for the message source based on updated reputation data associated with the message source, the updated reputation data indicating a decreased likelihood that electronic messages from the message source are unwanted by the intended recipients; and
allowing messages sent from the message source to reach the intended recipients at a second time when the second reputation score is attributed to the message source. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
