NIST 800-171

Is your PCB Supplier’s Cybersecurity Up-to-Par?
NIST 800-171 Compliance for PCB Manufacturers

In today’s interconnected digital landscape, safeguarding sensitive information is not just a priority—it’s a necessity. For businesses engaged with U.S. government contracts, compliance with cybersecurity standards is essential to protect Controlled Unclassified Information (CUI). One critical framework for ensuring this is the National Institute of Standards and Technology (NIST) Special Publication 800-171, which outlines security requirements for protecting CUI within non-federal systems and organizations.

For PCB manufacturers, compliance with NIST 800-171 is increasingly significant, as the electronics industry often intersects with sensitive defense, aerospace, and other government-related sectors. Understanding the framework and its implications is vital for PCB manufacturers, as it ensures they can protect their customers' sensitive data, meet federal standards, and maintain their reputation as trusted suppliers in critical industries.

Likewise, for PCB buyers, ensuring your manufacturing and assembly partners are compliant with these cybersecurity guidelines is critical - whether it’s a government contract or not.

What is NIST 800-171 Compliance?

NIST 800-171 establishes guidelines to protect CUI—a classification for information that requires safeguarding (but is not classified) under national security. The directive provides a structured approach to ensure that non-federal organizations handling CUI can maintain its confidentiality.

First issued in 2015 and made mandatory for Department of Defense (DoD) contractors in 2017, NIST 800-171 is rooted in the Federal Information Security Management Act (FISMA) and aims to mitigate risks associated with cyberattacks, data breaches, and unauthorized access. The framework specifies 110 controls divided across 14 families of requirements, ranging from access control to system integrity.

The Department of Defense increasingly requires its suppliers to adhere to NIST 800-171 through its Defense Federal Acquisition Regulation Supplement (DFARS).

These standards apply to various organizations, including contractors, manufacturers, and suppliers working with federal agencies or handling CUI in any capacity.

Why PCB Manufacturers Need NIST Compliance

PCB manufacturers often serve industries that rely on secure and precise technology, such as defense, aerospace, and healthcare / medical / instrumentation. As such, they frequently encounter contracts or projects involving CUI including:

• Schematics, manufacturing, and assembly data
• Sensitive emails
• Sensitive contact information details
• Other application notes and details

Key Requirements of NIST 800-171

To comply with NIST 800-171, organizations must implement robust security measures, grouped into 14 categories:

1. Access Control: Restrict system access to authorized users and processes, including employees and subcontractors.
2. Awareness and Training: Ensure personnel and subcontractors understand cybersecurity risks and policies.
3. Audit and Accountability: Maintain logs and ensure accountability for system activities.
4. Configuration Management: Enforce secure configurations for systems and software.
5. Identification and Authentication: Use strong authentication methods for system access.
6. Incident Response: Establish procedures for detecting, reporting, and responding to security incidents.
7. Maintenance: Perform system maintenance while safeguarding sensitive data.
8. Media Protection: Securely handle and dispose of physical and digital media.
9. Personnel Security: Screen individuals accessing CUI, including all entities involved in the supply chain such as employees, suppliers, and subcontractors.
10. Physical Protection: Restrict physical access to systems containing CUI.
11. Risk Assessment: Regularly evaluate risks to organizational systems.
12. Security Assessment: Periodically review security measures for compliance.
13. System and Communications Protection: Securely transmit data.
14. System and Information Integrity: Detect and respond to security vulnerabilities promptly.

An additional non-technical requirement is to develop, implement, and maintain a security program, including policies and a System Security Plan.

For suppliers of bareboard PCBs and PCB assembly, implementing these requirements means safeguarding customer designs, intellectual property, and sensitive specifications against cyber threats.

Beyond Compliance: Positioning for the Future - CMMC 2.0

NIST 800-171 compliance is not just a regulatory obligation but a foundation for advanced cybersecurity initiatives. The Cybersecurity Maturity Model Certification (CMMC), for instance, builds upon NIST requirements, creating a tiered certification system for DoD contractors.

The Cybersecurity Maturity Model Certification (CMMC) 2.0 program, recently finalized, refines and streamlines the original framework, introducing three distinct levels of certification to match the sensitivity of the government data involved in contracts:

• Level 1 (Foundational): This tier addresses basic safeguarding requirements and applies to contractors handling Federal Contract Information (FCI). It is based on 17 controls and requires an annual self-assessment.
• Level 2 (Advanced): For contractors handling Controlled Unclassified Information (CUI), this level incorporates the 110 controls from NIST SP 800-171. A subset of these contractors will undergo third-party assessments every three years, while others may only need self-assessments.
• Level 3 (Expert): Designed for the highest level of CUI sensitivity, Level 3 combines the controls from NIST SP 800-171 with an additional 24 controls from NIST SP 800-172. Third-party assessments are mandatory every three years.

The CMMC program underscores a risk-based approach to cybersecurity, ensuring contractors align with tailored requirements based on their risk exposure and the type of information they handle. For PCB manufacturers and suppliers, understanding and adopting the appropriate CMMC level is essential to meet DoD requirements and maintain trust as a secure partner.

Evaluating PCB Partners: A Buyer’s Checklist

By searching for PCB partners that have achieved NIST compliance, PCB buyers ensure they have a partner that has cybersecurity and data protection at the forefront of their processes; and will continue to do so for future compliance requirements and challenges.

Here are actionable steps you can take as a PCB buyer to vet potential suppliers - whether you’re buying for a federal contract or not:

1. Request Certification or Compliance Documentation
   • Ask potential PCB manufacturing partners for evidence of NIST 800-171 compliance or equivalent certifications such as Cybersecurity Maturity Model Certification (CMMC). Documentation should outline their implementation of the required security controls, as defined by NIST SP 800-171.
2. Evaluate Cybersecurity Policies
   • Request an overview of the manufacturer’s cybersecurity policies. Ensure they have protocols for:
     • Access control (restricting unauthorized access to sensitive data).
     • Incident response (plans for identifying, reporting, and mitigating breaches).
     • System integrity and data monitoring mechanisms.
3. Understand Their Supply Chain Security
   • Confirm whether your PCB partner ensures cybersecurity compliance across their supply chain, including brokers and component suppliers. A compliant partner must flow down and enforce similar standards among subcontractors.
4. Understand Their Role in Protecting CUI
   • Ask for clarity on how they handle Controlled Unclassified Information (CUI), such as Gerber files, application notes, and sensitive communications. Ensure they encrypt data, limit access, and follow physical security protocols for servers and storage.

Why This Matters for PCB Buyers

By ensuring that your PCB manufacturing partner complies with NIST 800-171, you protect your intellectual property from cyber threats, avoid potential breaches of contract, and meet any regulatory obligations tied to your industry. Cybersecurity is no longer optional; it’s a necessity for buyers and their partners.
