Auto-classify data assets

No more manual updates: use our auto-classification via policy rules to classify data assets and protect your more sensitive data.

PreviousClassification PoliciesNextWhat are Change Requests?

Last updated 11 months ago

Adding classifications manually might be a time-consuming task, especially if it's your first time on decube. Instead, you can opt to add it via our auto-classification workflow via the Policy rules, where you can set up keywords or via regex to detect matching asset names across multiple data sources.

Set up your policy rules

From any classification policies page, you can click on Set up new rule to access the new rule setup workflow.

  1. Select the data sources to apply the rules.

  2. Select the rule type. You can choose either to input a keyword or a regex to match strictly or approximately.

    • Optionally, if we detect new assets that have been added to your data sources, we can also add the classification automatically if you check the checkbox for Auto-add new assets to this rule.

  3. Click on Fetch assets. All assets that match according to your rule type will be shown.

Masking type - Hierarchy for masking

When multiple classification policies are applied to the column, the masking type selected if they are different, will follow a certain hierarchy to be shown to the user, with the highest priority masking type applied. You can view the below masking type sorted from highest to lowest priority:

  • SHA-256

  • First four characters

  • Last four characters

  • Email masking (eg. ********@domain.com)

  • Hash* (eg. *****)

  • Nullify

Select one of the several masking types to be applied. This will take effect in the section where dynamic masking is applied.

The creation, modification, and deletion of a rule will require an approval workflow before it is reflected in your organization. You can read more on the here.
