(https://www.icompaas.com) **NIST SP 800-171 Rev. 3**·Requirement `3.4.12`·high·Component: **Configuration Management** ## What this control requires > This control requires issuing systems or system components with specific configurations for individuals traveling to high-risk locations, based on organization-defined security requirements. Upon return, the systems or components must undergo additional security measures, such as device inspection, purging, or reimaging, to mitigate the increased threat exposure during travel. This control supports the Travel Security Configuration Management capability within the Configuration Management (3.4) family. > > — NIST SP 800-171 Rev. 3, Requirement 3.4.12 ### In plain English This control requires issuing systems or system components with specific configurations for individuals traveling to high-risk locations, based on organization-defined security requirements. In practice, this means you can prove you device management-level controls on a defined cadence. ## Why it matters DoD contractors and their subcontractors must implement all 100 SP 800-171 requirements to keep CUI handling contracts. Gaps are scored against the SPRS scoring methodology; below a 110-point starting score, each unmet requirement deducts points and a below-threshold score can disqualify a bid. This control is rated **high**. Auditors expect a named owner, a remediation SLA, and a tooling artefact that evidences continuous operation. ## What an auditor looks for A C3PAO conducting a CMMC Level 2 assessment uses NIST SP 800-171A objectives. They expect a System Security Plan (SSP), Plan of Action & Milestones (POA&M) for any gaps, and objective evidence (configurations, ticket records, training records) for every requirement. Within **Configuration Management**, the assessor will trace your implementation back to the catalogue reference (Requirement 3.4.12) and look for objective evidence on the latest two assessment cycles. ## How to implement #### Cloud Posture **CSPM.** Run Wiz / Prisma / Defender for Cloud / Security Command Center over every account; auto-ticket findings above your accepted-risk threshold. #### Configuration Management **Policy-as-code.** Codify the control as Service Control Policies (AWS), Azure Policy initiatives, or Organisation Policy (GCP) so the platform enforces what the document promises. **IaC.** Gate Terraform / Pulumi / CloudFormation changes with Checkov / tfsec / OPA so misconfigurations never reach production. **Drift.** Run a CSPM (Wiz / Prisma / Defender for Cloud / Security Command Center) over every account and route findings to a single risk register. #### Network Security **AWS.** VPC Flow Logs to S3, default-deny security groups, AWS Network Firewall for north-south, and Transit Gateway for hub-and-spoke segmentation. **Azure.** NSGs with deny-by-default, Azure Firewall Premium with TLS inspection, Private Endpoints for PaaS, and Microsoft Defender for Cloud's secure score for drift. **GCP.** VPC Service Controls perimeters around sensitive APIs, Cloud NGFW Enterprise for L7 inspection, Private Service Connect for managed services. ### Operational checklist - **Device.** Document the trigger, the owner and the cadence. - **Protection.** Document the trigger, the owner and the cadence. - **Configuration.** Document the trigger, the owner and the cadence. - **System.** Document the trigger, the owner and the cadence. - **Risk.** Document the trigger, the owner and the cadence. - **Scope:** management, configuration, device inspection, security, individuals, protection, system components. ## Evidence to collect - **Infra Scan.** Continuous infrastructure-posture telemetry — AWS Config, Azure Policy compliance, GCP Organisation Policy, Wiz / Prisma findings. Infrastructure posture tooling (AWS Config, Azure Policy, Nessus) verifies platform hardening. Focus: System and Component Configuration for High-Risk Areas. ## Common pitfalls - Treating CSPM findings as a backlog instead of a hot queue: findings older than the policy SLA accumulate until the auditor asks why. - Manual cloud-console changes that never make it back to Terraform — drift accumulates until the next outage forces a reconciliation. - Default-allow egress rules; East-West traffic with no segmentation; jump hosts on the public internet with password auth. - Pilot MDM rollouts that quietly exclude executives or engineers; carving out the highest-risk users is the most common audit failure. ## How it maps to other frameworks Computed from shared tags, control component and key-operation subjects — handy when you are reconciling controls across an audit. - [**NIST SP 800-53 Rev. 5 CM-2** — Baseline Configuration](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/cm-2-baseline-configuration) - [**BSI C5:2020 HR-06** — Confidentiality agreements](https://support.icompaas.com/compliance/bsi-c5-2020/hr-06-confidentiality-agreements) - [**CIS Controls v8 18.4** — Validate Security Measures](https://support.icompaas.com/compliance/cis-controls-v8/18-4-validate-security-measures) - [**ISO/IEC 27001:2022 A.5.34** — Privacy and protection of personal identifiable information (PII)](https://support.icompaas.com/compliance/iso-27001-2022/a-5-34-privacy-and-protection-of-personal-identifiable-information-pii) ## Related controls in NIST SP 800-171 Rev. 3 - [**Requirement 3.4.1** — Baseline Configuration](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-4-1-baseline-configuration) - [**Requirement 3.4.6** — Least Functionality](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-4-6-least-functionality) - [**Requirement 3.4.11** — Information Location](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-4-11-information-location) - [**Requirement 3.14.8** — Information Management and Retention](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-14-8-information-management-and-retention) - [**Requirement 3.13.6** — Network Communications - Deny by Default - Allow by Exception](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-13-6-network-communications-deny-by-default-allow-by-exception) - [**Requirement 3.4.3** — Configuration Change Control](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-4-3-configuration-change-control) ## References - [NIST Computer Security Resource Center — NIST SP 800-171 Rev. 3](https://csrc.nist.gov/pubs/sp/800/171/r3/final) - Catalogue identifier: `Requirement 3.4.12` Topics: governance riskcloud postureconfiguration managementnetwork securityendpoint protection ## Related compliance guidance - [NIST SP 800-171 and CMMC: a practical guide to protecting CUI in the cloud](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3): Start with the full NIST SP 800-171 implementation guide — scope, roadmap, evidence and how the assessment runs. - [NIST SP 800-53 Rev. 5: a practical implementation guide for cloud teams](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5): The catalogue 800-171 is tailored from, and the basis of the FedRAMP Moderate baseline your cloud providers must meet for CUI. - [ISO/IEC 27001:2022 compliance: a practical implementation guide](https://support.icompaas.com/compliance/iso-27001-2022): If commercial customers ask for a certificate as well, most 800-171 controls can be evidenced once and mapped to Annex A.
