2.2 Federation Assurance Level 1 (FAL1)

FAL1 provides a basic level of protection for federation transactions and allows for a wide range of use cases and deployment decisions.

At FAL1, the federation protocol SHOULD apply assertion injection protection, as discussed in Sec. 3.11.1. The federation transaction SHOULD be initiated by the RP.

At FAL1, the IdP SHALL sign the assertion using approved cryptography. The RP SHALL validate the signature using the verification key associated with the expected IdP. The signature protects the integrity of the assertion contents and allows for the IdP to be verified as the source of the assertion.

At FAL1, the assertion SHALL be audience-restricted to a specific RP or set of RPs, and the RP SHALL validate that it is one of the targeted RPs for the given assertion. Each RP in the audience SHALL enforce replay protection mechanisms in the assertion to ensure that the same assertion is not accepted by a given RP multiple times. An assertion with multiple audiences could be accepted by multiple RPs but only once by each RP.

At FAL1, federated identifiers SHOULD NOT contain plaintext personal information, such as usernames, email addresses, employee numbers, etc.

At FAL1, the trust agreement MAY be established by the subscriber during the federation transaction, as discussed in Sec. 4.3.2. Alternatively, the trust agreement MAY be established prior to the federation transaction (i.e., a “pre-established” trust agreement), as discussed in Sec. 4.3.1.
