Cyber Requirements for DoD Suppliers: What Small and Mid-Sized Manufacturers Need to Know
If your manufacturing company supplies parts or services to the Department of Defense (DoD), chances are you’re hearing about cybersecurity requirements more often. These rules aren’t just bureaucratic hurdles—they’re essential protections that keep sensitive information safe and ensure your organization can continue working with the government.
This post breaks down what you need to understand about cybersecurity requirements as a small or mid-sized manufacturer working with the DoD. We’ll cover what’s expected, why it matters, and practical steps to get compliant—even if you're not a tech expert.
Why Cybersecurity Matters for DoD Suppliers
The DoD handles sensitive national security information, like defense plans, technology data, and supply chain details. If this information falls into the wrong hands, it can threaten security and compromise military operations.
Because of this, the Department of Defense enforces cybersecurity standards to protect their data—and your business must meet these standards to continue working as a supplier. Failure to comply can lead to losing contracts or being removed from the approved supplier list.
Key Cybersecurity Standards: NIST SP 800-171
What is NIST SP 800-171?
Most DoD suppliers are required to implement cybersecurity controls based on the NIST Special Publication 800-171. This set of guidelines outlines how to protect Controlled Unclassified Information (CUI) in non-federal systems.
Core Requirements
The standards cover 14 control areas, including:
Access Control: Limiting who can see or change info.
Awareness and Training: Ensuring employees know security basics.
Audit and Accountability: Keeping track of who accesses data.
Configuration Management: Maintaining secure system setups.
Incident Response: Having a plan if something goes wrong.
How to approach these controls
For small and mid-sized companies, implementing NIST 800-171 might seem daunting, but it’s manageable if broken into steps. Focus on the basics: secure your network, control physical and digital access, and train your staff on cybersecurity best practices.
Assessing Your Current Security Posture
Conduct a Gap Analysis
Start by understanding where your company stands. Ask yourself:
Do we have antivirus and firewall protections in place?
Are access controls in use to limit system access?
Do employees follow secure password practices?
Have we trained staff on recognizing phishing emails?
If you're unsure, consider hiring a cybersecurity consultant or using self-assessment tools provided by trusted sources like CMMC Accreditation Body or the Department of Defense’s own resources.
Identify Risks and Prioritize
Find vulnerabilities—like outdated software or weak passwords—and address those first. Remember: you don’t need to fix everything at once. Small, consistent improvements add up over time.
Implementing Cybersecurity Measures
Basic Steps for Small Manufacturers
Update Software Regularly: Keep all systems and programs current to patch security flaws.
Control Access: Limit system login to necessary personnel. Use unique passwords and change them periodically.
Back Up Data: Regularly save copies of critical files in secure, off-site locations.
Train Employees: Conduct simple cybersecurity training sessions to recognize phishing and avoid risky behaviors.
Secure Network Connections: Use strong Wi-Fi encryption, and consider VPNs for remote access.
Advanced Steps (as needed)
If your contract or risk assessment indicates, you may need to implement multi-factor authentication (MFA), intrusion detection systems, or detailed audit logs. These are more complex but essential for higher cybersecurity maturity.
Preparing for Certification and Audits
Once your measures are in place, document everything. Maintain records of policies, trainings, software updates, and incident responses. This documentation will be crucial during audits or if you’re asked to verify compliance.
Many companies find it helpful to develop a formal cybersecurity plan aligned with NIST standards. This plan should detail your controls, procedures, and responsibilities.
Resources and Support
Getting started doesn’t mean you have to do everything alone. The Cybersecurity and Infrastructure Security Agency (CISA) offers resources tailored for small businesses. Additionally, industry associations often provide guidance on DoD cybersecurity requirements.
Final Thoughts
Meeting DoD cybersecurity requirements is about protecting your company’s reputation and securing your place as a trusted supplier. While the standards can seem complex, approaching them step-by-step makes the task manageable. Focus on basic controls, train your staff, and keep up with updates. In doing so, you'll help safeguard national security and ensure your business can continue thriving in the defense supply chain.
If you need help navigating these requirements or developing a cybersecurity plan, consider consulting with professionals who understand both manufacturing and cybersecurity. Remember: cybersecurity isn't just an IT issue—it's a core part of your business resilience.
