NONDESTRUCTIVE INTERCEPTION OF SECURE DATA IN TRANSIT

In a data level security environment, the data level security mechanism operates on plaintext data. Data level security operations identify a point in the information stream where plaintext data is available for interception. Typically this is a point in the processing stream just after the native DBMS decryption functionality has been invoked. A database monitor intercepts and scrutinizes data in transit between an application and a database by identifying a transition point between the encrypted and plaintext data where the cryptographic operations are invoked, and transfers control of the data in transit to a database monitor application subsequent to the availability of the data in plaintext form.
