Test sets, metrics, and details about the tools used during test, evaluation, validation, and verification (TEVV) are documented.
NIST AI RMF (in the playbook companion) has not defined MRE 2.1; however, Seclea Platform defines the relevant checks to this control requiring:
A detailed description of the TECC tools adopted by the organisations. The Seclea Platform or other sources can provide these tools, which the organisation must list in a comprehensive document and ensure they are regularly used. If the Seclea Platform provides the tools, they can be integrated directly as additional checks.
