Abstract: Heuristic classification is integrated with statistical classification to classify an input data set. Heuristic conditions or rule are assigned heuristic rule identifiers, which are inserted into the feature list of a statistical classifier. In this manner, the heuristic rule identifiers are treated as statistical features, the counts for which are incremented or flagged when an input data set satisfies the associated heuristic rule. Thereafter, the statistical classification score therefore includes the contribution of the heuristic rule in its result.

Abstract: An integrated electronic data communications system enforces a data integrity policy to validate the electronic data (e.g., determine whether the electronic data is a corporate asset or an unwanted threat). Upon validation, data is archived in real time in a searchable repository, encrypted/decrypted automatically, and forwarded to a mobile device, if appropriate. Example electronic data that may be communicated through such a system may include without limitation email, VOIP data, FTP data, Web traffic, data communicated through a corporation's Virtual Private Network (VPN), etc.
