Abstract:
1. A method of scanning data comprising: receiving a request for network content at a scanning facility, the request received from a content requesting computing facility remote from the scanning facility, and the request including a source from which to retrieve the network content; performing a source lookup for the request at the scanning facility, wherein the source lookup requests data concerning the source of the request from a networked source lookup database, and wherein the networked source lookup database responds with a characterization of the source; retrieving the network content to the scanning facility; calculating a checksum of the network content; performing a checksum lookup on the checksum, wherein the checksum lookup is from a networked checksum lookup database that stores checksums for known malware content; and when the network content is not identified as malware based upon the checksum lookup, taking an action to protect the content requesting computing facility from malware based on the characterization of the source from the networked source lookup database.
