Abstract
A method and apparatus for scanning protected files for violations of a Data Loss Prevention (DLP) policy is described. In one method, an inventory of protected files in the computing system is created. The inventory stores hashes and policy violation statuses of the protected files. The method obtains a running instance of a data object corresponding one of the protected files when the one protected is created, opened, or saved. The method extracts decrypted data from the running instance of the data object and scans the decrypted data to detect a violation of a DLP policy. The method creates a hash of the one protected file and stores the hash and a policy violation status of the one protected file. The method monitors the protected files of the inventory. When the method detects a transfer of one of the protected files being monitored, the method performs an action when the policy violation status indicates that the one protected file violates the DLP policy.
