Fingerprint specific field combinations in a database table?
To fingerprint specific field combinations, first create a fingerprint classifier for the database table:
- In the Data Security module of the Security Manager, go to the page.
- Select Database Fingerprinting.
- Click New in the toolbar at the top of the content pane, then select Database Table Fingerprinting.
- 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.
- Continue through the wizard, and click Finish when done.
- 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.
- Go to the page.
- Select a rule, then click Edit.
- Select Condition from the rule properties.
- Click Add, then select Fingerprint from the drop-down list.
- Select the content classifier to add, then define the field combination and threshold to use.
- Click OK.
- To add the same classifier again with a different field combination and threshold, repeat steps 4 - 6.
- 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.
