Data leakage prevention for cloud and enterprise networks

摘要

Apparatuses, methods and articles of manufacture for performing data leakage prevention are provided. Data leakage prevention may be performed by determining a signature of a transmitted document, the transmitted document being in transit to a location beyond a network boundary. The signature of the transmitted document is compared with one or more signatures of documents authorized to be transmitted beyond the network boundary. The transmitted document is prevented from being transmitted beyond the network boundary if the signature of the document does not correspond to a signature of a document authorized to be transmitted beyond the network boundary.

主权项

1. An apparatus comprising:
a data storage device; and a processor communicatively coupled to the data storage device, the processor in cooperation with the data storage device configured to:
determine a signature of a transmitted document based on a logical function, a byte value, a position value and a byte of a random number, the transmitted document being in transit to a location beyond a network boundary;determine a subset of one or more signatures of documents authorized to be transmitted beyond the network boundary, the subset corresponding to the position value of the transmitted document;compare the signature of the document with the subset of one or more signatures; andprevent the transmitted document from being transmitted beyond the network boundary if the signature of the transmitted document does not correspond to a signature of a document authorized to be transmitted beyond the network boundary.
