Which one of the following control steps is usually NOT performed in data warehousing
applications?

A.
Monitor summary tables for regular use.

B.
Control meta data from being used interactively.

C.
Monitor the data purging plan.

D.
Reconcile data moved between the operations environment and data warehouse.

Explanation:
Not B: It is important to control meta data from being used interactively by
unauthorized users. “Data warehouses and data mining are significant to security professionals for
two reasons. First, as previously mentioned, data warehouses contain large amounts of potentially
sensitive information vulnerable to aggregation and inference attacks, and security practitioners
must ensure that adequate access controls and other security measures are in place to safeguard
this data.” Pg 192 Tittel: CISSP Study Guide
Not C: “The data in the data warehouse must be maintained to ensure that it is timely and valid.
The term data scrubbing refers to maintenance of the data warehouse by deleting information that
is unreliable or no longer relevant.” Pg 358-359 Krutz: The CISSP Prep Guide: Gold Edition

Not D: “To create a data warehouse, data is taken from an operational database, redundancies
are removed, and the data is “cleaned up” in general.” Pg 358 Krutz: The CISSP Prep Guide: Gold
