- Controlled Unclassified Information (CUI)
- Information that the government creates or possesses, or that an entity creates or possesses for or on behalf of the government, that a law, regulation, or government-wide policy requires or permits an agency to handle using safeguarding or dissemination controls.
- Removable Media
- Portable data storage devices, such as USB flash drives, external hard drives, CDs, DVDs, and SD cards, that can be easily connected to and removed from a computer system. These are common vectors for data transfer and potential security risks.
- NIST SP 800-171
- A publication by the National Institute of Standards and Technology that provides recommended security requirements for protecting the confidentiality of CUI when it resides in nonfederal systems and organizations. It serves as the foundation for CMMC Level 2.
Who Benefits from Robust Removable Media Controls?
- Defense Contractors & DoD Subcontractors — Organizations directly engaged in defense projects, whether prime contractors or subcontractors, relying on CUI for their operations and needing to meet CMMC Level 2 and NIST 800-171 requirements to secure new contracts and retain existing ones globally.
- Aerospace & Engineering Firms — Companies that design, develop, and manufacture components for defense systems, often handling sensitive blueprints, technical specifications, and proprietary data that constitutes CUI across their international development teams.
- Research & Development Institutions — Entities conducting classified or unclassified research for defense agencies, requiring strict controls over intellectual property and research data that may be stored on or transferred via removable media.
- Managed Service Providers (MSPs) to the DIB — Technology service providers supporting defense contractors who may inadvertently handle CUI or require CMMC compliance themselves to maintain their client base within the defense industrial base across different continents.
Frequently Asked Questions
What is CMMC MP.L2-3.8.7 Removable Media control?
CMMC Level 2 control MP.L2-3.8.7, derived directly from NIST SP 800-171 control 3.8.7, mandates that organizations restrict system access for removable media and prohibit the use of unauthorized removable media on organizational systems. This control aims to prevent data exfiltration, CUI exposure, and the introduction of malware through portable storage devices. It covers policies, procedures, and technical configurations to manage, control, and protect CUI when it interacts with or resides on removable media within the organizational environment, ensuring a consistent security posture whether operations are local or international.
Why is removable media a significant risk for CUI?
Removable media, such as USB drives, external hard drives, and SD cards, pose a significant risk to CUI due to their portability and ease of use. They can be easily lost, stolen, or intentionally misused, leading to unauthorized disclosure or exfiltration of sensitive information. Furthermore, they can be vectors for malware introduction if used on untrusted systems and then connected to organizational networks. For organizations globally handling CUI, a single unprotected removable device can compromise an entire system or expose vast amounts of sensitive defense data, impacting national security and leading to severe compliance penalties.
How does Jun Cyber help with MP.L2-3.8.7 compliance?
Jun Cyber provides a holistic approach to MP.L2-3.8.7 compliance. We assist organizations worldwide in developing robust policies and procedures for the secure use, storage, and disposal of removable media. Our services include implementing technical controls like mandatory encryption for CUI on removable devices, configuring access restrictions, deploying data loss prevention (DLP) solutions, and establishing a centralized inventory and tracking system for all media. We also conduct comprehensive staff training to embed secure practices and ensure ongoing vigilance, ensuring compliance across all operational jurisdictions.
What are the key technical requirements for this control?
The key technical requirements for MP.L2-3.8.7 include: 1) **Encryption:** Mandating encryption for all CUI stored on removable media. 2) **Access Control:** Restricting the types of removable media that can be used on organizational systems and defining authorized users and purposes. 3) **Scanning:** Implementing solutions to scan removable media for malicious content before allowing connection to systems. 4) **Sanitization:** Ensuring proper sanitization or destruction of removable media containing CUI before disposal or reuse, adhering to standards like NIST SP 800-88. 5) **Centralized Management:** Utilizing tools to manage, audit, and enforce removable media policies across the enterprise, regardless of geographic spread.
Does this control apply to personal devices used for work?
Yes, if personal devices are used to store, process, or transmit CUI, or if they connect to organizational systems that handle CUI, they fall under the scope of CMMC Level 2 and NIST SP 800-171, including MP.L2-3.8.7. Organizations must have clear policies prohibiting unauthorized personal removable media, or implement strict controls (e.g., encryption, virtual desktop infrastructure, secure containers) to ensure CUI remains protected and segregated. The control's intent is to secure CUI regardless of the specific device or its ownership, emphasizing the need for robust organizational policies and technical enforcement across all user contexts, including remote or international workers.
What is the difference between NIST SP 800-171 3.8.7 and CMMC MP.L2-3.8.7?
NIST SP 800-171 3.8.7 is the foundational control that mandates restricting system access for removable media and prohibiting unauthorized removable media. CMMC MP.L2-3.8.7 is essentially the CMMC Level 2 implementation of this NIST control. While the core requirement is the same, CMMC adds an 'assessment' component, meaning organizations must demonstrate not just that they have policies and procedures, but that they are actively implemented, managed, and reviewed to ensure effectiveness. Jun Cyber focuses on helping organizations achieve this demonstrated implementation and continuous adherence required for CMMC certification.
