ABSTRACT:
A network traffic manager detects an attempt by a computer to communicate with a remote site over a computer network. The network traffic manager queries a database containing descriptions of known legitimate sites for an entry describing the remote site, and determines whether the remote site is to be treated as suspicious or legitimate. If there is no entry describing the site in the database, the network traffic manager treats the site as suspicious. If there is an entry describing the remote site, the network traffic manager compares the entry to the site itself, to determine whether the site conforms to the database description. If it does not so conform, the site is treated as suspicious. If the site does conform to its description, it is considered legitimate. In some embodiments, additional tests are performed.
