NIST Special Publication 800-63-4 digital identity guidelines outline how organizations should verify identities and authenticate users, securely exchange authentication data across systems, and federate across systems. The latest edition includes additional granularity in assurance levels IAL, AAL and FAL as well as requirements for modern identity proofing techniques like FIDO passkeys and subscriber-controlled wallets.

NIST IAL3 Verification

NIST 800-63-4 is an essential framework for modern digital identity management. It facilitates risk mitigation with anti-phishing authentication, device-bound and syncable passkeys, subscriber-controlled wallets and robust cryptographic authenticators; in addition to encouraging secure federation practices.

The fourth version maintains the tripartite model of IAL, AAL, and FAL while updating requirements to match modern technology. These updates include increasing focus on phishing-resistant authentication as well as formalizing inclusion of FIDO passkeys and user controlled wallets as well as new cryptographic binding in federated transactions.

At its core, business risk mitigation begins by identifying which assurance levels are needed to address them. They don't need to match exactly; organizations often opt for lightweight identity proofing (IAL1) paired with strong authentication (AAL3) as this balances cost, usability and risk reduction. Furthermore, an ideal solution will offer step-up reproofing as user risks change for continuous security while simultaneously decreasing attack surfaces and cyber liability insurance costs.

NIST IAL3 Compliance

The NIST IAL3 Digital Identity Guidelines offer an excellent starting point for increasing cybersecurity and improving user experience. The framework offers different assurance levels for identity proofing, authentication and federation to ward off advanced attacks such as fraud, data theft and repudiation.

IAL1 requires linking an applicant's claimed identity with that of a specific real-life individual; IAL2 verifies whether an authenticator relates to an entity claiming ownership over evidence; and IAL3 checks integrity of federated assertions - these varying requirements aim to restrict attacks requiring large quantities of information.

Trustswiftly makes meeting nist 800-63-4 ial3 compliance easy and convenient with our remote solution, which enables employees to independently verify their identity through a kiosk that accepts photos, video and audio recordings of themselves. This saves both money and time while sparing users the disruption caused by in-person proofing sessions that disrupt workflow. Furthermore, this system generates comprehensive reports that can be shared with your 3PAO auditor.

NIST IAL3 FedRAMP High Identity Proofing

NIST SP 800-63-4 provides an effective framework for measuring confidence in digital identities. By breaking assurance down into three dimensions -- Identity Assurance Level (IAL), Authentication Assurance Level (AAL), and Federation Assurance Level (FAL), organizations can analyze threats, service impacts, user populations and dynamically choose appropriate assurance levels.

NIST 800-63-3 is signaling a significant shift away from email OTPs and SMS-based authentication protocols, towards prioritizing stronger, phishing-resistant protocols that ensure agencies use resilient authentication mechanisms that truly safeguard against modern threats.

Trust Swiftly can help you meet IAL3 requirements cost effectively using an inexpensive browser page that opens to begin the fedramp high identity proofing process. Once an enrollee begins their proofing, an agent can instantly connect live to their device and record face images and evidence documents for verification using real world documents - this process can either take place in-person or remotely for IAL2 and IAL3. An agent may step up their verification if additional biometric checks or documents need to be verified with additional documents are necessary.

NIST IAL3 Security

NIST IAL3 Security is the highest assurance level defined by the National Institute of Standards and Technology (NIST), offering stringent requirements to verify someone as being who they claim they are - in-person nist ial3 verification with video, facial recognition with liveness detection, document authentication, as well as rigorous evidence validation are just some of these measures required to meet it.

At IAL3, Identity Proofing involves direct comparison of enrollee biometrics against images captured from strong identification evidence to verify whether or not the person presenting information about themselves is indeed the person they claim they are. The combination of document validation, biometric comparison and direct oversight reduces risks of impersonation and fraud while simultaneously increasing user adoption rates while decreasing application rejection rates.

NIST 800-63-3 lays the framework for an identity management strategy that ensures phishing resistance, promotes strong federated identity practices and utilizes FIDO passkeys to protect organizations against man-in-the-middle attacks. Furthermore, this document recommends continuous evaluation programs as part of ongoing monitoring programs to stay abreast of new threats in an ever-evolving threat landscape.
