- Identification of the data storage objects holding information at risk of mining, such as warehouses or aggregated stores · Policy repository / GRC workspace
- Documented data mining prevention and detection techniques in use, including query rate and volume thresholds · Policy repository / GRC workspace
- Definition of which mining techniques are authorised, so the detection distinguishes analysts from adversaries · Policy repository / GRC workspace
First move
Mostly documents and reviews. Pull the 1 system-held artefact from your Identity provider / directory on a schedule; put the documents under version control with an owner and review date, and log each review as a dated record with a named reviewer.
Common gaps auditors find
- Protection applied to the production database while the analytics replica holding the same data is uncontrolled
- No threshold defined, so bulk extraction looks identical to normal query load
- Authorised analytics never baselined, producing enough noise that detections are routinely dismissed
