Best Practices for Handling, Storing, and Marking Controlled Unclassified Information (CUI)

Introduction

Handling Controlled Unclassified Information (CUI) is a critical responsibility for any organization involved in government contracts, particularly within the defense sector. The proper management of CUI is not only vital for maintaining compliance with regulations like the Cybersecurity Maturity Model Certification (CMMC) but also crucial for national security. Recent breaches, such as the F-35 data theft by Chinese actors, underscore the importance of safeguarding sensitive information. This blog delves into the best practices for handling, storing, and marking CUI, with insights drawn from a recent expert webinar.

Understanding CUI and Its Importance

Controlled Unclassified Information (CUI) refers to information that requires safeguarding or dissemination controls pursuant to law, regulation, or government-wide policy. The CMMC framework emphasizes the need for organizations to understand and protect CUI. As Robert Ashcraft, a CMMC expert, highlighted during the webinar, improper handling of CUI can lead to severe consequences, including significant penalties for both prime contractors and their subcontractors.

Key Takeaway: The significance of CUI lies not only in compliance but also in national security. As Kelly Kendall, CEO of KC Strategic Services, pointed out, breaches can lead to adversaries like China gaining critical technological insights, such as in the F-35 case.

Best Practices for Handling CUI
  • Implementing Effective Access Controls
    One of the primary strategies for protecting CUI is implementing robust access controls. This involves ensuring that only authorized personnel have access to CUI. As Robert mentioned, some prime contractors have adopted a color-coded system for restricted areas within their facilities. For example:
    • Red Zones: Restricted to personnel with full clearance.
    • Blue Zones: Accessible to personnel with lower levels of clearance.

This simple yet effective method reduces the risk of unauthorized access during facility tours or visits.

  • Regular Training and Awareness Programs
    Ongoing training is crucial for ensuring that all employees understand how to handle CUI appropriately. Robert Ashcraft emphasized the need for minimal yet effective training sessions to instill the importance of CUI protection. Organizations should utilize resources like the NIST standards for marking and handling CUI, available online.

Best Practices for Storing CUI
  • Physical Security Measures
    For CUI stored in physical form, organizations must implement stringent physical security measures. This includes secure storage rooms with controlled access, surveillance, and regular audits to ensure compliance.
  • Data Encryption and Secure Storage
    For digital CUI, encryption is non-negotiable. Steve Poar from Lifeline Data Centers highlighted the importance of secure Virtual Desktop Infrastructure (VDI) Enclave Solutions, particularly for small to medium-sized defense contractors. These solutions provide an alternative to GCC High, offering secure environments that ensure CUI is stored and transmitted safely.

Best Practices for Marking CUI
  • Using Standardized Markings
    Marking CUI correctly is essential for ensuring that it is handled properly throughout its lifecycle. The National Archives and Records Administration (NARA) provides standardized banners and markings that organizations can adopt. These markings indicate the level of sensitivity and any restrictions on dissemination.

  • Practical Examples of Marking CUI
    During the webinar, Kelly Kendall stressed that while contracts often specify how CUI should be marked, organizations must be proactive in ensuring compliance. For example, documents that contain sensitive information but were created before CUI regulations were established should be reviewed and marked appropriately if referenced or used in the future.

Conclusion

Handling, storing, and marking CUI is a critical responsibility for organizations involved in government contracts, particularly in the defense sector. By implementing effective access controls, providing regular training, securing both physical and digital CUI, and using standardized markings, organizations can ensure compliance with CMMC and other regulations. More importantly, they can protect national security interests, preventing adversaries from exploiting sensitive information.
