4.1.1 FAL1

NIST PIV and digital identity SP 800-217 (Draft)
All changes in this version
first version loaded 4 Federation Assurance Level (FAL) 788 part of 4.1

Title

FAL1

Control

FAL1 allows federation in a wide variety of situations, particularly when the results of a risk assessment show that the risk is low, and the value of making the federated connection outweighs the complexities of implementing higher FALs. The establishment of the trust agreement and the determination of the PIV IdP MAY be established at the behest of the subscriber. The PIV IdP SHOULD be the home agency IdP for the agency if the home agency IdP is known for the target agency by the RP. The RP SHOULD audit and review all accepted PIV IdPs.

As defined in [SP800-63C] , at FAL1, the IdP MAY use front-channel presentation of the assertion. However, if the assertion contains private or sensitive information and is presented over the front-channel, an encrypted assertion SHALL be used.
