Organize data classification for data policies
Data classification enables you to set up a secure environment for your organization. Data can be classified, for example, according to its level of sensitivity, value, and importance for your organization as required by your own data policies. This helps you establish reliable security controls for data protection.
To organize data classification you must be assigned the Admin role for the Watson Knowledge Catalog app. Classification applies to the whole account. It only shows the asset classifiers of the catalog that belongs to the currently logged in account.
Classification offers automatic profiling of assets in catalogs. You can use algorithms in the rule builder to automatically detect assets that contain, for example, sensitive personal information (SPI). To automatically classify the columns of a data asset in a catalog with data policies enforced, open this asset and click the catalog Profile tab.
You can assign the following classifiers to data assets in catalogs using policy rules:
- Asset classifiers are selected manually for data assets in catalogs on the Overview page of a data asset. You can create a policy rule that automatically classifies data in the catalog accordingly.
- Attribute classifiers use job libraries or executable files. They can be applied by the rule builder to automatically classify data according to the rule you define. The attribute classifiers and classifier groups are provided by IBM.
To manually classify an existing asset in a catalog with data policies enforced, preview this asset in the catalog Overview tab and edit the Classification property. You can also choose this classification (such as sensitive personal information) and user restrictions when:
- Adding a data asset to a catalog or when publishing a data asset from a project to your catalog.
- Editing asset properties.
