Immuta Discover provides identifiers out-of-the-box to recognize and tag data. Users can then utilize classification frameworks and build them to apply tags based off those identifier tags and their own catalog tags.
Tune identification frameworks and identifiers first to adjust where Discovered tags are applied. Because classification frameworks can apply classification tags from the Discovered tags, tuning SDD should come first and will have trickle-down effects on classification. Customizing SDD requires some initial work but will automate data tagging for all data sources in the future.
Follow the steps below to tune SDD for your data:
Add a few data sources to your new framework: This will remove the tags from any previous identification frameworks and re-run identification with your new framework. From here, either continue to edit identifiers to reconfigure the applied tags, or if you are happy with the results, proceed to the next step.
After SDD has applied entity tags, any active classification frameworks will automatically reapply their tags to account for any changes to Discovered tags. It may be necessary to adjust the classification tags based on your organization's data, security, and compliance needs.

Target some data sources to manually review tags:
Navigate to the data dictionary for the data source by opening the Data Sources page and selecting a data source. Click the Data Dictionary tab to open the data dictionary.
The data dictionary lists the data source columns, with details about the name, data type, and a list of the tags on each column. Assess whether the tags are accurate to your data.
Tags may be unexpected but still accurate to your data. Additionally, they may have been applied because they were found to be the best match from the identifiers in the framework.
If you want to improve SDD and personalize it to your data, assess why the tag was applied to your data:
Is the identifier incorrectly matching your data and irrelevant to your organization? Delete the identifier that applied the tag from the identification framework.
Is the identifier incorrectly matching this specific column, but correct in other places? It must have been the most correct match found by identification. Create a better match by completing the following steps:
Add the identifier to the identification framework so this column is correctly matched by identification.
If you want to remove the unexpected tags, use one of the following how-to guides:
Ensure the Discovered tags are applied properly by adjusting SDD.
Remove any excess tags. Note that classification tags build off of other tags, so removing a single classification or Discovered tag can have trickle-down effects on the data source.
If you were expecting some sensitive data to be tagged and it is not, enable additional tags using one of the following how-to guides:
Ensure the Discovered tags are applied properly by adjusting SDD.
Add additional tags. Note that classification tags build off of other tags, so adding a single classification or Discovered tag can have trickle-down effects on the data source.
Requirement: Immuta permissions GOVERNANCE and AUDIT
Tags can be edited on an individual basis for each data source. If broad changes to the classification framework are necessary to re-tag your data, use the frameworks API.
Navigate to the Data Sources page and select the data sources that you assessed and noted issues.
Click the Data Dictionary tab.
Delete unnecessary tags by clicking on the tag you want to remove from the column, and select Disable from the tag side sheet.
To add tags,
Click Add Tags in the Actions column.
Begin typing the name of the tag you want to add in the Search by Name field and select the tag from the dropdown list.
Click Add.
