What is the primary objective of **WCAG**?

**The primary objective of WCAG is to provide internationally recognized, technology-agnostic guidelines for making web content accessible to people with disabilities.** WCAG, developed by the W3C Web Accessibility Initiative, organizes requirements under four principles—**Perceivable, Operable, Understandable, Robust (POUR)**—with 13 guidelines and testable success criteria at Levels A, AA, and AAA. It addresses visual, auditory, motor, cognitive, and other needs while improving usability for all users.

Who is legally or professionally required to comply with **WCAG**?

**WCAG compliance is required for U.S. public-sector entities under DOJ Title II rules mandating WCAG 2.1 Level AA by 2026/2027, and increasingly for private organizations via ADA litigation and procurement.** Federal agencies follow Section 508 (aligned to WCAG), EU entities adhere via EN 301 549 and the European Accessibility Act (effective June 28, 2025), and vendors face contractual obligations through VPATs. Enterprises in healthcare, finance, and e-commerce comply to mitigate lawsuits.

Does **WCAG** require an external audit or third-party certification?

**WCAG does not require external audits or third-party certification for conformance.** Conformance depends solely on meeting all success criteria up to the chosen level (e.g., AA), full pages, complete processes, accessibility-supported technologies, and non-interference. Organizations self-assess using W3C techniques, automated tools like axe-core, and manual testing; optional VPATs or independent audits support procurement and legal defense.

How often should an assessment for **WCAG** be performed?

**WCAG assessments should be performed continuously via CI/CD integration, with quarterly manual audits and annual full reviews.** Integrate automated scans (e.g., axe-core) into development pipelines to prevent regressions, conduct expert manual/AT testing per release for critical paths, and schedule comprehensive evaluations yearly or post-major updates to ensure ongoing conformance across full pages and processes.

What are the consequences of non-compliance with **WCAG**?

**Non-compliance with WCAG exposes organizations to ADA lawsuits (e.g., 4,605 U.S. cases in 2023), settlements with remediation mandates, and procurement disqualification.** Courts reference WCAG as the accessibility benchmark; penalties include fines, injunctive relief, and costs exceeding $100k per case, plus reputational damage and lost contracts under Section 508 or EN 301 549.

An **WCAG** be mapped to other international frameworks?

**No, WCAG mappings to other frameworks are outside its standalone scope.** WCAG provides its own normative success criteria and conformance model, used independently as the global benchmark by regulators worldwide.

What is the first step to begin implementing **WCAG**?

**The first step to implement WCAG is to conduct a baseline assessment using the W3C Preliminary Review method across high-impact pages and processes.** Inventory digital assets, run automated scans (axe, WAVE), perform manual keyboard/screen reader tests, and prioritize remediation by WCAG 2.1 AA success criteria for full pages and complete user flows like checkout.

What is the primary objective of **NIST 800-171**?

**NIST SP 800-171 provides recommended security requirements for protecting the confidentiality of Controlled Unclassified Information (CUI) in nonfederal systems and organizations.** It applies to components that process, store, transmit CUI, or provide protection for such components, tailored from SP 800-53 Moderate baseline. Revision 3 (May 2024) supersedes Revision 2, organizing requirements into 17 families including new areas like Supply Chain Risk Management.

Who is legally or professionally required to comply with **NIST 800-171**?

**Nonfederal organizations handling CUI via federal contracts, grants, or agreements must comply with NIST SP 800-171.** This includes DoD contractors and subcontractors under DFARS 252.204-7012 for covered contractor information systems processing Covered Defense Information (CDI). Applicability is contractually enforced, excluding COTS-only acquisitions.

Oes **NIST 800-171** require an external audit or third-party certification?

**No, NIST SP 800-171 does not require external audits or third-party certification.** Organizations perform self-assessments using SP 800-171A procedures (examine/interview/test). DoD may mandate higher assurance via CMMC Level 2 (C3PAO) or SPRS scoring, but the standard itself relies on SSP and POA&M documentation.

How often should an assessment for **NIST 800-171** be performed?

**Assessments for NIST SP 800-171 should be performed annually at minimum, with continuous monitoring for changes.** SP 800-171A Rev 3 supports ongoing validation; DoD requires annual SPRS reaffirmation for self-assessments, plus event-driven reviews for system changes or incidents.

What are the consequences of non-compliance with **NIST 800-171**?

**Non-compliance with NIST SP 800-171 results in contract ineligibility, termination, and potential False Claims Act liability.** DoD contractors face SPRS score penalties (down to -203), disqualification from bids, 72-hour incident reporting failures, and remedial demands under DFARS 252.204-7012.

An **NIST 800-171** be mapped to other international frameworks?

**Yes, NIST SP 800-171 includes explicit mappings to other frameworks in its appendices.** Revision 2 Appendix D maps to SP 800-53 and ISO 27001; it aligns with NIST CSF categories, enabling integration into existing ISMS without duplication.

What is the first step to begin implementing **NIST 800-171**?

**The first step to implement NIST SP 800-171 is defining the system boundary and scoping CUI components.** Identify assets that process/store/transmit CUI or provide protection, using enclave isolation (e.g., subnetworks, firewalls) to limit scope, then develop the System Security Plan (SSP).
