Data classification describes the sensitivity level of the data and the type of content of the data. Data classification helps catalog members understand the data and identifies the type of data to restrict in data protection policies.
Data assets are classified by these methods:
Asset classifications: Describe the type of sensitive information in the asset, for example, sensitive personal information, personally identifiable information, confidential, or none. You choose the classification of an asset when you add the asset to a governed catalog. You cannot add a classification to assets in ungoverned catalogs. The classification is visible to all catalog members on the Overview page of the asset. The owner of the asset and other asset or catalog members with the Editor or Admin role can change the classification by editing the asset.
Attribute classifiers: Describe the type of content of each column in a relational data asset, for example, city, account number, or credit card number. Attribute classifiers are logically grouped into classifier groups. The attribute classifiers and classifier groups are provided by IBM. In governed catalogs, relational data assets are automatically profiled and assigned attribute classifiers. In ungoverned catalogs, you can choose to profile a relational data asset and choose which attribute classifiers to assign. All catalog users can see the attribute classifiers in the asset preview on the Overview and Profile pages of the asset.
You can include asset classifications and attribute classifiers in data protection policy rules to identify the type of data to control.
You can rename asset classifications and attribute classifiers by associating them with business glossary terms that make sense for your organization.
