Abstract

An exemplary system for providing a network resource address reputation service may comprise a server computer configured to determine whether an event associated with a network resource address matches event signature(s) in network security device(s). If the event matches a signature, a reputation score for the network resource address may be generated. If the network resource address is not present in a first malicious network resource address database, the network resource address in association with the reputation score may be stored in a second malicious network resource address database. If the network resource address is present in the first malicious network resource address database, the reputation score may be modified to indicate a more negative reputation for the network resource address. The network resource address may then be stored in association with the modified reputation score in a second malicious network resource address database.
