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. Derived from SP 800-53 Moderate baseline, Revision 3 (superseding r2 on May 14, 2024) organizes requirements into 17 families, emphasizing scoping via CUI security domains with boundary protections like firewalls.

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 targets systems not operated on behalf of agencies under FISMA.

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.** Compliance is demonstrated via self-assessment using SP 800-171A procedures (examine/interview/test), producing a System Security Plan (SSP) and Plan of Action and Milestones (POA&M). Contractual regimes like CMMC Level 2 may require C3PAO assessments.

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 ongoing validation via SSP updates and POA&M reviews. DoD requires annual SPRS score submissions for Basic assessments.

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

**Non-compliance with NIST SP 800-171 risks contract ineligibility, termination, and remediation demands under DFARS 252.204-7012.** It includes 72-hour cyber incident reporting failures, SPRS score penalties (down to -203), False Claims Act liability, and exclusion from DoD procurement.

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

**Yes, NIST SP 800-171 Appendix D provides explicit mappings to other frameworks.** r2 maps to SP 800-53 and ISO 27001; it aligns with NIST CSF categories. r3 enhances traceability to SP 800-53 r5, supporting integration into established programs.

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

**The first step is defining the system boundary and scoping CUI components per SP 800-171 guidance.** Identify assets processing/storing/transmitting CUI or providing protection, using enclaves with firewalls and flow controls to limit scope, followed by SSP development.

What is the primary objective of **ISO 14064**?

**ISO 14064 provides requirements and guidance for quantifying, reporting, and verifying greenhouse gas (GHG) emissions and removals.** The standard family comprises three parts: **ISO 14064-1:2018** for organizational-level inventories, **ISO 14064-2:2019** for project-level reductions/removals, and **ISO 14064-3:2019** for validation/verification. It enforces five principles—**relevance, completeness, consistency, transparency, accuracy**—to ensure credible, comparable GHG assertions for organizations, projects, and stakeholders.

Who is legally or professionally required to comply with **ISO 14064**?

**No organizations are legally required to comply with ISO 14064, as it is a voluntary international standard.** Professionally, it applies to organizations (companies, governments, NGOs), project developers (e.g., renewable energy, CCS), and verification bodies needing credible GHG inventories for regulatory readiness (e.g., EU CSRD, California SB-253), investor disclosures, emissions trading, supply-chain demands, and climate finance.

Does **ISO 14064** require an external audit or third-party certification?

**ISO 14064 does not require external audit or third-party certification.** Parts 1 and 2 encourage but do not mandate independent validation/verification under **ISO 14064-3** or by bodies compliant with **ISO 14065:2020**. In practice, third-party assurance is often necessary for credibility in markets, regulations, and green finance, providing reasonable or limited assurance via risk-based evidence gathering.

How often should an assessment for **ISO 14064** be performed?

**ISO 14064 assessments should be performed annually to maintain consistency and enable trend analysis.** Organizational inventories under **ISO 14064-1** require a defined reporting period (typically calendar year), with base-year recalculations for significant structural changes (e.g., acquisitions). Project monitoring under **ISO 14064-2** follows specified plans, and verification under **ISO 14064-3** aligns with reporting cycles or stakeholder needs.

What are the consequences of non-compliance with **ISO 14064**?

**Non-compliance with ISO 14064 carries no direct penalties, as it is voluntary.** Indirect consequences include rejected GHG claims in emissions trading/carbon markets, regulatory scrutiny (e.g., under CSRD/SB-253 where ISO alignment is expected), investor distrust, supply-chain exclusion, greenwashing litigation risks, and lost access to climate finance due to unverifiable inventories lacking **ISO 14064-3** assurance.

An **ISO 14064** be mapped to other international frameworks?

**Yes, ISO 14064 can be mapped to other international frameworks, notably the GHG Protocol Corporate Standard.** Its five principles and Scopes 1-3 directly align with GHG Protocol requirements for inventories, enabling dual reporting. **ISO 14064-1** supports organizational boundaries (equity share/control), while **Part 2** aids project baselines/additionality compatible with crediting schemes.

What is the first step to begin implementing **ISO 14064**?

**The first step to implement ISO 14064 is defining organizational and operational boundaries.** Per **ISO 14064-1**, select consolidation approach (e.g., equity share or operational control), identify emission sources/sinks across Scopes 1-3, and document relevance to ensure inventories reflect economic reality while adhering to the five principles.
