NIST 800-171 might feel overwhelming at first—with its 110 control requirements across 14 families—but not all of them require a massive overhaul of your IT infrastructure. In fact, there are several practical controls you can implement today to start your journey toward full compliance.
Here are 10 actions you can take now:
1. Restrict System Access (3.1.1)
Limit access to systems and CUI based on user roles. Ensure only authorized personnel have access.
2. Use Multi-Factor Authentication (3.5.3)
Strengthen user authentication by adding a second layer (e.g., OTP, biometrics).
3. Enforce Password Complexity (3.5.7)
Establish strong password policies: length, complexity, and periodic updates.
4. Implement Audit Logging (3.3.1)
Enable logging to monitor who accesses what and when—critical for breach investigations.
5. Limit Data Transfers (3.1.20)
Restrict the use of portable media or cloud sharing for CUI unless it’s fully secured.
6. Provide Security Awareness Training (3.2.1)
Educate your team on phishing, social engineering, and basic cyber hygiene.
7. Patch Systems Regularly (3.14.1)
Have a process to identify and apply software patches promptly.
8. Backup Critical Data (3.8.6)
Ensure you have encrypted, offline backups of CUI to restore from in case of a breach.
9. Encrypt CUI in Transit and At Rest (3.13.8 & 3.13.16)
Use industry-standard encryption to protect sensitive data wherever it lives or moves.
10. Develop an Incident Response Plan (3.6.1)
Prepare for cyber incidents with documented steps and escalation protocols.
Final Thought
You don’t need to solve all 110 requirements overnight. Start with these ten, build momentum, and consider conducting a formal gap analysis to map out your next steps. NIST 800-171 is not just about compliance—it’s about securing the future of your business.
