NIST 800-171 implementation requires small businesses to address 110 security controls across 14 control families to protect Controlled Unclassified Information (CUI). For North Carolina defense contractors and manufacturers, this framework is the foundation of CMMC Level 2 certification and continued eligibility for Department of Defense contracts.
Key takeaway: According to NIST SP 800-171 Rev 2, organizations must implement all 110 security requirements to achieve full compliance. However, the DoD Assessment Methodology assigns weighted values of 1, 3, or 5 points to each control, meaning North Carolina small businesses can prioritize high-impact controls first while building toward complete implementation.
With 11,496 manufacturing firms in North Carolina and 90% employing fewer than 100 workers, the challenge of implementing enterprise-grade security controls on small business budgets is real. This guide breaks down each control family into actionable steps that High Point, Greensboro, Charlotte, and Piedmont Triad small businesses can execute without dedicated security teams.

Understanding the NIST 800-171 Framework
NIST Special Publication 800-171 establishes security requirements for protecting CUI in nonfederal systems. Published by the National Institute of Standards and Technology, it serves as the baseline for CMMC Level 2 certification that most defense contractors require.
How the 14 Control Families Work Together
The 14 control families form a layered defense strategy. Each family addresses a specific security domain, and together they create comprehensive protection for sensitive defense information. According to the DoD Assessment Methodology, the 110 controls include 42 controls weighted at 5 points, making those the highest priority for your initial implementation efforts.
Rev 3 Changes on the Horizon
NIST released SP 800-171 Revision 3 in May 2024, consolidating 110 controls into 97 requirements across 17 families (adding Planning, System and Services Acquisition, and Supply Chain Risk Management). However, the DoD has not yet mandated Rev 3 compliance through Class Deviation 2024-O0013, meaning contractors should focus on Rev 2 compliance now while monitoring the transition timeline.
Control Family 1: Access Control (22 Requirements)
Access Control represents the largest control family with 22 requirements, many weighted at 5 points. This family governs who can access your systems and what they can do once authenticated.
Priority Actions for NC Small Businesses
- Implement role-based access control (RBAC) for all systems handling CUI
- Enforce least-privilege principles across user accounts
- Configure session timeouts and login attempt limits
- Document and review access permissions quarterly
- Separate duties for critical operations to prevent single-user risk
Resource Estimate
Small businesses in the Greensboro and Winston-Salem area can typically implement basic access controls within 4-6 weeks using existing directory services like Microsoft Active Directory or Azure AD.
Control Family 2: Awareness and Training (3 Requirements)
All personnel handling CUI must understand their security responsibilities. This family requires documented training programs with regular refresher courses.
Priority Actions
- Develop role-based security training for all employees
- Conduct annual security awareness training with attendance tracking
- Provide specialized training for system administrators and IT personnel
- Document training completion and maintain records for assessment
Control Family 3: Audit and Accountability (9 Requirements)
Audit controls ensure that system activities are tracked, reviewed, and protected from tampering. Several controls in this family carry 5-point weights.
Priority Actions
- Enable system-level logging on all CUI-handling systems
- Implement centralized log collection (SIEM or log management tool)
- Configure alerts for security-relevant events
- Protect audit logs from unauthorized modification or deletion
- Review audit records regularly for anomalies
Cost Consideration
North Carolina small businesses can leverage cloud-based SIEM solutions starting at $500-1,500 per month, significantly less than deploying on-premises alternatives that many Charlotte and Raleigh enterprises use.
Control Family 4: Configuration Management (9 Requirements)
Configuration management ensures systems are securely configured and changes are controlled throughout their lifecycle.
Priority Actions
- Establish secure baseline configurations for all system types
- Implement change control processes with documentation
- Restrict and monitor software installation privileges
- Maintain hardware and software inventories
- Apply the principle of least functionality (disable unnecessary services)
Control Family 5: Identification and Authentication (11 Requirements)
This family requires strong authentication for all users accessing CUI systems. Multiple controls carry 5-point weights.
Priority Actions
- Implement multi-factor authentication (MFA) for all network access
- Enforce strong password policies (complexity, length, expiration)
- Use unique identifiers for all users (no shared accounts)
- Authenticate devices connecting to organizational networks
- Disable inactive accounts after defined periods
Preferred Data Insight: MFA implementation alone addresses multiple high-weight controls and provides immediate security improvement. For Piedmont Triad manufacturers, we typically deploy MFA across all systems within 2-3 weeks.
Control Family 6: Incident Response (3 Requirements)
Organizations must prepare for, detect, and respond to security incidents affecting CUI.
Priority Actions
- Develop and document an incident response plan
- Test the plan annually through tabletop exercises
- Designate incident response team roles and responsibilities
- Establish reporting procedures for security incidents
- Track and document all incidents and lessons learned
Control Family 7: Maintenance (6 Requirements)
System maintenance must be performed securely, with proper oversight of maintenance personnel and tools.
Priority Actions
- Schedule and document routine maintenance activities
- Supervise maintenance personnel without proper clearance
- Sanitize equipment before off-site maintenance
- Approve and monitor remote maintenance sessions
- Verify maintenance tools are free from malicious code
Control Family 8: Media Protection (9 Requirements)
This family addresses the protection of CUI stored on physical and digital media throughout its lifecycle.
Priority Actions
- Mark media containing CUI with appropriate designations
- Control access to media containing CUI
- Sanitize or destroy media before disposal or reuse
- Implement encryption for CUI stored on portable media
- Control media transport outside controlled areas
Control Family 9: Personnel Security (2 Requirements)
Personnel security ensures that individuals accessing CUI are vetted and that access is promptly removed when no longer needed.
Priority Actions
- Screen individuals before granting access to CUI systems
- Revoke access immediately upon personnel termination or transfer
- Document personnel security procedures
Control Family 10: Physical Protection (6 Requirements)
Physical security controls protect the facilities and equipment housing CUI from unauthorized access.
Priority Actions
- Limit physical access to CUI processing areas
- Maintain visitor logs and escort visitors in controlled areas
- Monitor physical access with cameras or access logs
- Protect power equipment, cabling, and infrastructure
- Control access to output devices (printers, monitors)
NC-Specific Consideration
Many North Carolina manufacturing facilities near High Point, Burlington, and Thomasville have combined office and production environments. Physical separation of CUI-processing areas from general manufacturing floors requires careful planning.
Control Family 11: Risk Assessment (3 Requirements)
Regular risk assessments identify vulnerabilities and guide security investment priorities.
Priority Actions
- Conduct annual risk assessments covering all CUI systems
- Perform vulnerability scanning at least quarterly
- Remediate vulnerabilities based on risk prioritization
- Document risk assessment findings and track remediation
Control Family 12: Security Assessment (4 Requirements)
Organizations must periodically evaluate whether their security controls are effective and properly implemented.
Priority Actions
- Develop a system security plan (SSP) documenting all controls
- Conduct periodic security assessments against the SSP
- Develop and implement plans of action and milestones (POA&Ms) for gaps
- Monitor control effectiveness on an ongoing basis
Control Family 13: System and Communications Protection (16 Requirements)
This family protects data in transit and establishes network security boundaries. Several high-weight controls fall here.
Priority Actions
- Implement network segmentation to separate CUI environments
- Encrypt CUI in transit using FIPS-validated cryptography
- Deny network traffic by default (allowlist approach)
- Monitor and control communications at system boundaries
- Implement DNS filtering and email security controls
Cost Consideration for Durham and Research Triangle Businesses
Firewall upgrades and network segmentation typically cost $5,000-$25,000 for small businesses, depending on network complexity. Cloud-based solutions can reduce upfront costs significantly.
Control Family 14: System and Information Integrity (7 Requirements)
This family addresses malicious code protection, security monitoring, and system patching.
Priority Actions
- Deploy endpoint protection on all CUI systems
- Implement automated patch management
- Monitor system security alerts from vendors and CISA
- Scan for unauthorized system changes regularly
- Report security flaws through proper channels
Building Your Implementation Roadmap

Phase 2: Structure (Months 4-6)
Build the documentation and processes required for assessment:
- [ ] Create System Security Plan (SSP)
- [ ] Document all policies and procedures
- [ ] Implement configuration baselines
- [ ] Deploy network segmentation
- [ ] Conduct initial risk assessment
Phase 3: Maturation (Months 7-12)
Address remaining controls and prepare for third-party assessment:
- [ ] Complete security awareness training program
- [ ] Implement media protection controls
- [ ] Conduct vulnerability assessments
- [ ] Perform internal security assessment
- [ ] Address all POA&M items
Key takeaway: North Carolina small businesses should budget 12-18 months for full implementation. According to industry analysis, Rev 3 will require 32% more verification procedures, making early Rev 2 compliance the best preparation strategy.
Common Implementation Gaps for NC Small Businesses
Based on assessments of defense contractors throughout the Piedmont Triad, Charlotte metro, and Research Triangle regions, the most common gaps include:
Gap 1: Incomplete System Security Plans
Many small businesses lack comprehensive SSPs documenting their security environment. This single document is foundational to every other control family.
Gap 2: Missing Audit Log Reviews
While businesses often enable logging, they rarely conduct regular log reviews. Automated alerting helps bridge this gap without adding staff.
Gap 3: Insufficient Network Segmentation
Flat networks where CUI systems share infrastructure with general business systems violate multiple high-weight controls. Even basic VLAN segmentation provides significant improvement.
Gap 4: No Incident Response Testing
Having a written plan without testing it through tabletop exercises leaves organizations unprepared for actual incidents.

Frequently Asked Questions
How long does NIST 800-171 implementation take for a small business?
Most North Carolina small businesses require 12-18 months for full implementation across all 14 control families. Businesses that start with high-weight controls can achieve significant security improvement within the first 3-4 months while building toward complete compliance.
What is the difference between NIST 800-171 Rev 2 and Rev 3?
NIST 800-171 Rev 3 consolidates 110 controls into 97 requirements and adds three new control families (Planning, Supply Chain Risk Management, and System and Services Acquisition). However, the DoD has not mandated Rev 3 compliance yet. Contractors should implement Rev 2 now and prepare for the eventual transition.
Can a small business implement NIST 800-171 without a dedicated IT security team?
Yes. Many North Carolina small businesses successfully implement NIST 800-171 by partnering with a managed security provider like Preferred Data Corporation. This approach provides access to security expertise and tools without the cost of full-time security staff, which is particularly valuable for Piedmont Triad manufacturers with fewer than 50 employees.
What happens if my business is not fully compliant with NIST 800-171?
Non-compliance can result in loss of DoD contract eligibility, False Claims Act liability, and SPRS score penalties that make your business uncompetitive for defense work. According to the DoD Assessment Methodology, contractors must submit accurate SPRS scores, and misrepresentation carries serious legal consequences.
How does NIST 800-171 relate to CMMC 2.0?
CMMC Level 2 requires implementation of all 110 NIST 800-171 Rev 2 controls, verified by a third-party assessment organization (C3PAO). Achieving NIST 800-171 compliance is the direct pathway to CMMC Level 2 certification, which most defense contractors handling CUI will need by November 2026.
