ATT&CK v10 Data Sources Support

[isaisabel]

As a user of the ATT&CK Navigator, I want to be able to select techniques by their associated data sources in the search & multiselect interface the same way I do mitigations, groups, and software.

See the data sources STIX beta here for test data and data model documentation.

Note: Techniques map to data components and from data components to data sources. In the search & multiselect interface users should be able to select at the data component level, with the data source name prepended; e.g:

• Command: Command Execution
• File: File Metadata
• File: File Modification

This is similar to the sub-techniques and techniques listed in search & multiselect, however unlike in that case the data source itself cannot be selected since it has no mappings to techniques itself.
