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 NIST SP 800-53 Moderate baseline with a confidentiality focus. Revision 3 (May 2024) supersedes Revision 2, organizing requirements into 17 families including new additions like Planning (PL), System and Services Acquisition (SA), and Supply Chain Risk Management (SR).

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

**Nonfederal organizations handling CUI via federal contracts, grants, or agreements must implement 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; exclusions apply to COTS-only acquisitions or systems operated on behalf of the government.

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

**No, NIST SP 800-171 does not mandate external audits or third-party certification.** Organizations must develop a **System Security Plan (SSP)** documenting implementation and a **Plan of Action and Milestones (POA&M)** for gaps, using SP 800-171A procedures (examine/interview/test). DoD may require SPRS score submission or CMMC Level 2 assessments via C3PAO for prioritized contracts.

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 r3 supports self-assessments (Basic), DoD reviews (Medium), or independent high-confidence assessments. DoD requires annual SPRS reaffirmation; CMMC Level 2 mandates triennial C3PAO recertification with annual affirmations.

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

**Non-compliance with NIST SP 800-171 risks contract ineligibility, termination, and exclusion from DoD awards.** DFARS 252.204-7012 mandates 72-hour cyber incident reporting; failures trigger remediation demands, SPRS score penalties (down to -203), False Claims Act liability, and reputational damage barring future bids.

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

**Yes, NIST SP 800-171 Revision 2 Appendix D provides explicit mappings to NIST SP 800-53 and ISO 27001.** Revision 3 aligns closely with SP 800-53 r5; it also maps to NIST Cybersecurity Framework (CSF) categories. FedRAMP Moderate is often equivalent or more stringent for cloud, enabling control inheritance.

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

**The first step is to define the system boundary and inventory components processing, storing, or transmitting CUI.** Create data flow maps, isolate a CUI security domain using firewalls and controls, then conduct a gap analysis against the 97 r3 requirements (17 families) to build the SSP and POA&M.

What is the primary objective of **MAS TRM**?

**MAS TRM's primary objective is to promote sound and robust practices for technology risk governance and cyber resilience across financial institutions (FIs).** Per the January 2021 Guidelines Preface §1.4, it establishes sound governance and oversight while maintaining defence-in-depth controls to preserve confidentiality, integrity, and availability (CIA) of data and systems, proportionate to each FI's risk profile and service complexity (§2.2).

Who is legally or professionally required to comply with **MAS TRM**?

**MAS TRM applies to all financial institutions (FIs) supervised by MAS, including banks, insurers, capital market intermediaries, payment service providers, and fintech sandbox participants.** The Guidelines target FIs offering financial services reliant on technology (§2), with implementation commensurate to risk and complexity (§2.2); MAS considers observance during supervision, though not a legal standard of care (§2.2–2.3).

Oes **MAS TRM** require an external audit or third-party certification?

**MAS TRM mandates an independent internal audit function to assess TRM controls, governance, and risk management effectiveness, but does not require external audits or third-party certification.** Section 3.1.7 requires the board to ensure independent audit coverage; external penetration testing or assurance may support requirements like annual PT for internet-facing systems (§13.2.4), but is not formally mandated.

How often should an assessment for **MAS TRM** be performed?

**MAS TRM requires periodic reviews of policies, frameworks, and controls commensurate with risks, with specific cadences such as annual penetration testing for internet-facing systems.** Vulnerability assessments occur regularly based on criticality (§13.1.1); DR plans reviewed annually (§8.2.2); asset inventories and risk frameworks updated regularly (§3.3.2, §4.1.5); cyber exercises and PT after major changes (§13.2.4, §13.3).

What are the consequences of non-compliance with **MAS TRM**?

**Non-compliance with MAS TRM can result in supervisory actions including fines, license conditions, revocations, and executive prohibitions.** While not legally binding (§2.2), MAS considers "spirit of the Guidelines" in supervision; examples include S$27.45M AML/CFT fines across nine FIs and CMS license revocation for governance failures tied to technology lapses.

An **MAS TRM** be mapped to other international frameworks?

**Yes, MAS TRM aligns with frameworks like NIST CSF 2.0 and ISO 27001 through shared outcomes in governance, risk assessment, controls, and assurance.** Section 3.2.1 encourages incorporating industry standards/best practices; TRM's risk lifecycle (§4), defence-in-depth (§Preface), and CIA focus map to NIST's Identify-Protect-Detect-Respond-Recover-Govern and ISO's ISMS controls.

What is the first step to begin implementing **MAS TRM**?

**The first step is to establish board-approved technology risk governance, including a risk appetite statement and appointment of competent CIO/CISO roles.** Section 3.1 requires board oversight of the TRM framework, risk appetite approval (§3.1.7), and senior management to define roles (§3.1.3, §3.1.8), enabling proportional control design via asset inventories (§3.3).
