“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
