Trusted Digital Identity Solutions From Trustswiftly NIST 800-63-4

NIST's Special Publication 800-63-4 brings IAL3 compliance into the 21st century with more adaptive assurance levels for IAL3, AAL and FAL in digital identity management that help reduce fraud while safeguarding data.

Implement IAL2-aligned checks for standard users, and increase verification when risk increases. Capture all verification decisions, approvals and artifacts so security and compliance teams can easily defend against them.

Trustswiftly’s IAL3 software enables FedRAMP high identity proofing.

The IAL, AAL and FAL assurance levels are designed to minimize risks from identity proofing and authentication processes. Their primary goal is limiting fraud's adverse impacts on individuals - such as money or property loss, physical harm to health (physical or psychological), or damage to reputation; similarly these goals also serve to protect information assets while decreasing insider threat exposure for organizations.

The NIST 800-63-4 standard revolutionizes identity management by creating an adaptive risk-based Digital Identity Risk Management framework. This shift away from checklist-based requirements and emphasizes methods like strong FIDO passkeys which are resistant to phishing attacks; additionally it promotes threat assessment, service impacts assessment, user population considerations when choosing between an AAL, LAL or FAL solution; Fischer Identity's IAL3 software provides multiple levels of assurance through automated joiner/mover/leaver workflows with PIV cards as authenticators; SAML 2.0 authentication service with OIDC encryption as FAL1 as well as formal user-controlled wallets which host verifiable credentials with formal user wallets which strengthen FALs.

Trustswiftly is a longtime partner of many federal agencies and can assist organizations with assessing the need for higher assurance levels by starting small. A risk map can help organizations identify critical applications that require IAL/AAL/3 certification and select an implementation process accordingly. Once installed, resulting system can protect against scaled attacks such as data loss or theft as well as evidence falsification or repudiation and can prevent unauthorised access to confidential information while supporting secure interactions among users.

IAL3 software enables NIST SP 800-63-4 compliance.

NIST Special Publication 800-63 provides vital frameworks for identity proofing (IAL), authentication assurance levels (AAL), and federation assurance levels (FAL), making FedRAMP high compliance achievable by understanding their nuances.

Effective enterprise risk management is multidisciplinary by design and requires taking into account a variety of factors and expectations; when applied to digital identity these include information security, fraud, privacy concerns and user experience.

As such, security and usability trade-offs can be significant. For instance, mandating IAL-3 for all users might not be practical for small businesses that don't have enough staff and time to validate each customer photo ID manually. Avatier's software offers progressive security that enables businesses to only require higher levels of verification when absolutely necessary.

Avatier provides an all-in-one platform for IAL/AAL/FAL that offers organizations a convenient point of entry and allows them to quickly switch between levels of authentication. The system supports any type of authenticator - mobile phone included! For additional security measures, this CSP subscriber account lists authorized authenticators along with their attributes (to learn more please refer to Section 5 of [SP800-63A] or to its companion volumes of subscriber accounts, authenticators and attribute management) which then are utilized by an RP in making access or authorization decisions.

NIST SP 800-63-3 is still essential to building trust between digital identities. The 2025 publication of updated guidelines marks an essential shift away from checklist-based requirements towards risk-based Digital Identity Risk Management (DIRM) framework, mandating organizations to carefully consider threats and service impact before selecting their Identity Assurance Level (IAL), Authenticator Assurance Level (AAL), or Federation Assurance Level (FAL). NIST also strengthens authentication protocols by using IAL1 as an assurance level, encouraging phishing-resistant multifactor authentication and passwordless strong cryptographic authenticators like FIDO passkeys to promote strong authentication; and including the concept of subscriber-controlled wallets with verifiable credentials or mobile driver's licenses into the federation model.

Companies employing remote workers must undertake a radical, comprehensive overhaul of legacy software-only proofing processes. Flying employees around, booking hotels and giving up days of productivity just for an in-person verification session would not be sustainable in today's remote-first organization.

The new fedramp high identity proofing provides an opportunity to introduce a more robust and user-friendly nist ial3 verification process that can be performed remotely. According to its guidance, CSPs are required to limit their collection of personally identifiable information in order to confirm a claimed identity; this allows RPs to utilize CSP-provided attributes for pseudonymity within federated environments while linking claimed identities with real world identities for robust risk analyses. Fischer Identity's comprehensive IAM platform supports all these new requirements.

IAL3 software enables NIST SP 800-63-4 federation.

Ial3 identity verification software provide a core framework for digital identity management that updates our understanding of federation. They define separate assurance levels for proving identity, authenticating, and federation with flexibility for more granular risk assessments. Furthermore, claimed identities must be linked back to real identities through an attestation process to further strengthen risk assessments when authorizing over federated assertions.

These standards supplement but do not replace the information and IT security controls established through FISMA and NIST's RMF, with particular attention paid to authentication, encryption and federation of users gaining access organizational services over networks. [SP800-63A], [SP800-63B], and [SP800-63C] form part of these normative guidelines for authentication encryption federation accessing organizational services over networks.

Authentication relies on proof that a claimant owns and controls multiple forms of authentication devices, whether software-based journeys like PINs or hardware authentications such as smart cards. To be authenticated successfully, these authenticators must possess strong phishing resistance as well as secure functionality; also important is user experience. A person seeking to enroll in government benefit programs for instance may not be able to gain access if their identity cannot be proven over smart cards.
