NIST 800-63-4 outlines higher identity verification and authentication standards for federal systems accessed by employees, and introduces an organized Digital Identity Risk Management (DIRM) framework, moving away from checklist-oriented approaches toward considering threats, service impacts and users' capabilities.

The final version of AAL2 and AAL3 replaces email OTP with SMS-based authentication, dramatically downgrades SMS authentication, and officially incorporates phishing-resistant protocols like FIDO Passkeys into AAL2 and AAL3. Furthermore, both IALs and FALs have been modified for modern attacks risks, requiring stronger proofing processes as well as cryptographic binding in federated transactions.

Verification

Digital identity verification is the process of checking a person's real-life identity against what they claim they are online to ensure their claims are valid, especially for high-risk transactions such as government services and financial transactions. It involves verifying an individual through various forms of interactions such as phone, video and in person conversations to ascertain that they are who they say they are. Nist ial3 verification process includes more stringent proofing steps, including in-person interactions between applicant and trained CSP representative to compare their evidence against what has been provided. Furthermore, this system supports using additional authenticators beyond digital versions of passport or driver's license documents.

As with the IAL3 Biometric Pathway, the ial3 identity verification software allows for delivery of a mailed confirmation code as an authentication method that supports it. CSPs offering this as an option must keep a record in subscriber records detailing which pathways were taken to meet IAL2 outcomes and requirements.

Compliance

Many digital services require authentication due to legal, regulatory, or policy requirements. These requirements could pertain to access to personal information, protected data or subscriber accounts; online services must document whether they require authentication as well as their initial choice of assurance level (IAL).

NIST has established three identification assurance layers (IALs). Each requires increasing levels of proof. IAL1 should only be used in less sensitive applications and does not correspond with real people; while IAL3 should only be utilized for transactions that could pose significant harm to individuals or nations if compromised.

Fischer Identity's Zero Trust architecture makes it possible to meet the higher standards of NIST 800-63-4 with confidence, supporting continuous verification for future-proof security posture and providing continuous verification capabilities. A modern identity platform should provide full capabilities of IAL3 while offering seamless user experiences - this is what Fischer Identity delivers!

Fedramp

An effective digital identity standards framework is key to combatting fraud and protecting user data. Organizations granting access can gain greater peace of mind that the correct person has been granted entry. That is why governments require companies who offer digital services from offering these standards.

NIST 800-63-4 IAL3 is an updated security standard which modernizes traditional level-of-assurance models by creating a modular identity management framework, offering proofing and authentication under one unified definition, using phishing-resistant methods like FIDO passkeys for AAL2+ levels, formalizing subscriber controlled wallets (like mobile driver's licenses or verifiable credentials) as part of its federation model, among many other benefits.

The new framework emphasizes risk-based approaches and better aligns usability with security in an increasingly digital-centric world. For instance, it relaxes hardware requirements for higher assurance levels such as IAL2+. Furthermore, this document fosters a structured DIRM process and fosters more focus on mission delivery, public trust and individual users (such as equity and privacy issues) for improved decisions regarding ID&V processes that support this level of assurance - thus offering greater flexibility when selecting ID&V processes that support such assurance levels.

High Identity Proofing

Under NIST guidelines, identity proofing at level IAL3 provides organizations with the ability to assure with high confidence that an individual's claimed digital identity matches up with their real world identity. It requires an intensive verification process - document authentication, biometric comparisons and direct oversight are used - that ensures fraud risk mitigation while protecting relying parties against identity theft.

Trustswiftly Verified Identity Platform allows businesses to quickly implement a NIST compliant fedramp high identity proofing solution within weeks, using customized kiosks or turnkey kits. Our integrated system supports nist 800-63-4 ial3 compliance by verifying an individual's identity using chat, video, face verification with liveness detection and document authentication all from within a single system.

NIST 800-63-4 introduces not only a new assurance level but also enhances federation protocols by formally integrating phishing-resistant authenticators such as FIDO passkeys and user wallets into its federation model - these features will strengthen digital ID security for businesses meeting NIST requirements as well as protecting against ever-evolving threats.
