Column Classification Rules

Column Classification is a capability that is available to DSPM customers using the DLP detection engine.

Column Classification enables an organization as part of their DSPM data discovery and classification phase to understand structured data i.e. in databases and help classify these database columns based on a content inspection rule definition.

To get to Column Classification Rules, navigate to DLP > Rules and click the Column Classification Rules tab.

There are a number of predefined Column Classification Rules available and you can create additional rules.

Create a new Column Classification Rule

To create a new Column Classification rule:

1. Click New Column Classification Rule.
2. Enter a Rule Name.
3. Select your rules:
   • Header: Specify terms that are likely identifying what you would expect to see as the column header. For example, if you have a table with a column that specifies bank account numbers, you could use the terms, entities or custom entities that best describe what you are looking for.
   • Content: Specify the pattern to search for in the actual cells of the table. For example, if you expect bank account numbers, you could use a predefined entity or select a custom entity that best describes the data you are looking for.
4. Click Save.

You can edit or delete custom rules by clicking the … at the right of the rule.

To create entities that can be used in the Header or Content rule definition, see Select DLP Entity.

Using Column Classification Rules in DLP Profiles

You will notice in the DLP Profile configuration a new step called Column Classification Rules where you can select the rules to search for. To learn more, see DLP Profiles.
