Fingerprint specific field combinations in a database table?

To fingerprint specific field combinations, first create a fingerprint classifier for the database table:

  1. In the Data Security module of the Security Manager, go to the Main > Policy Management > Content Classifiers page.
  2. Select Database Fingerprinting.
  3. Click New in the toolbar at the top of the content pane, then select Database Table Fingerprinting.
  4. Work through the wizard as described in Creating a database fingerprint classifier section. On the Field Selection page, select Select up to 32 fields from a table, then select the table name and the field combination to fingerprint.
  5. Continue through the wizard, and click Finish when done.
  6. Run the fingerprint scan.

Next, add the new fingerprint classifier to a rule. The same classifier can be added more than once, selecting a different combination of fields and different thresholds to match against.

  1. Go to the Main > Policy Management > DLP Policies > Manage Policies page.
  2. Select a rule, then click Edit.
  3. Select Condition from the rule properties.
  4. Click Add, then select Fingerprint from the drop-down list.
  5. Select the content classifier to add, then define the field combination and threshold to use.
  6. Click OK.
  7. To add the same classifier again with a different field combination and threshold, repeat steps 4 - 6.
  8. Set up condition relations for the classifiers using the And, Or, and Customized options. For more information on setting up conditions, see Custom Policy Wizard Condition section.
