Missing Page Technique

In the case where a database maintains Separate Files, this Technique requires the removal of an entire file or files from the database to a Secure Storage Device that can be Removed From or Switched out of the System.

In the case of a database that Encapsulates the Files within itself, it is required that a full Copy of the Database be Removed to the Secured Storage Device, and the designated Table Logic Data be Defaulted to a Non Informational Value, or Removed from the freely available database.

Non Informational Values  i.e. Text fields = "Not Available".  Numeric fields = 0 and Date fields = Today's Date

The Secured File, or Database (now called Page One, in keeping with the book analogy) is then Accessed from this device by those Authorized to do so.  This affords a high level of Accountability to be placed on those with access rights and those charged with removing the file from the system.  This is Level One Security and is the highest level available with Database Security Paging, but only while Page One is maintained Separate from the Database Proper, or after it has been Removed from the System.

All applications of Database Security Paging should begin by attempting to achieve the Missing Page Technique.  If that can not be achieved, then an Alternative Technique that provides the Highest Security Level Possible should be chosen.  It is Vital that a Rigorous Attempt be made to analyze the files for Table Logic Data and to establish the Actual Daily Need for that data to remain present within the system, if this is an unavoidable requirement.
