2.3 Federation Assurance Level 2 (FAL2)

FAL2 provides a high level of protection for federation transactions by requiring additional protections against a variety of attacks on federated systems, including attempts to inject assertions into a federated transaction. All of the requirements for FAL1 apply at FAL2, except where overridden by more specific or stringent requirements here.

At FAL2, the assertion SHALL be strongly protected from assertion injection attacks, as discussed in Sec. 3.11.1. The federation transaction SHALL be initiated by the RP.

At FAL2, the assertion SHALL be audience restricted to a single RP. The RP SHALL enforce replay protection mechanisms in the assertion.

At FAL2, federated identifiers SHALL NOT contain plaintext personal information, such as usernames, email addresses, employee numbers, etc.

At FAL2, a trust agreement SHALL be established prior to the federation transaction taking place (i.e., a “pre-established” trust agreement), as discussed in Sec. 4.3.1.

IdPs operated by or on behalf of federal agencies that present assertions at FAL2 or higher SHALL protect signing keys that are used in the generation of assertions with mechanisms validated at [FIPS140] Level 1 or higher.
