Built-in Identifier Reference
Immuta comes with a set of built-in identifiers that look for common data types. These identifiers were written by Immuta's research and development team and cannot be deleted or edited by users. However, users can add these built-in identifiers to their own frameworks and edit the tags applied by them.
When using SDD with classification frameworks, it is recommended to use the default resulting tags listed in the table below for these built-in identifiers. This ensures that the framework rules apply sensitivity tags as intended.
Identifiers must match at least 90% of the sampled data to be tagged, with two exceptions noted below. See the How competitive pattern analysis works guide for more information about sampling and thresholds.
Deprecation notice
The following Discovered tags have been deprecated:
Discovered.Identifier DirectDiscovered.Identifier IndirectDiscovered.Identifier UndeterminedDiscovered.PCIDiscovered.PHIDiscovered.PII
New SaaS tenants will not see these tags applied by SDD. Current tenants relying on these tags for policies should contact their Immuta representative for support before these tags are removed from the product.
