Who Benefits from Robust Remote Access Confidentiality (AC.L2-3.1.13) Compliance?
- Defense Prime Contractors — Organizations directly contracting with government agencies requiring CMMC Level 2 certification, especially those with distributed teams or global partners accessing CUI, benefit from ensuring their remote access solutions meet stringent confidentiality requirements to maintain contracts and avoid penalties.
- DoD Subcontractors & Supply Chain Partners — Any company within the Defense Industrial Base (DIB) supply chain, regardless of size or location, that processes, stores, or transmits CUI, must adhere to AC.L2-3.1.13. Secure remote access is critical for collaboration and contractual obligations across international borders.
- Research & Development (R&D) Firms — Companies engaged in sensitive R&D projects involving CUI or intellectual property that require secure remote collaboration among scientists and engineers across various locations globally, need robust confidentiality controls to protect innovation and national security interests.

Frequently Asked Questions
What is CMMC AC.L2-3.1.13 and why is it important?
CMMC AC.L2-3.1.13, derived from NIST SP 800-171 control AC.3.1.13, mandates that organizations employ cryptographic mechanisms to protect the confidentiality of remote access sessions. This is critically important because remote access, whether by employees, contractors, or partners, creates a potential pathway for unauthorized access and data breaches. If CUI is transmitted over unencrypted or weakly encrypted remote connections, it becomes vulnerable to interception by malicious actors, leading to severe consequences for national security, intellectual property, and contractual obligations. Ensuring confidentiality prevents unauthorized disclosure of sensitive government information during transit.
What specific 'cryptographic mechanisms' are required for AC.L2-3.1.13?
For CMMC AC.L2-3.1.13, 'cryptographic mechanisms' generally refer to technologies and protocols that encrypt data to protect its confidentiality. This primarily includes the use of FIPS-validated Virtual Private Networks (VPNs) for establishing secure tunnels between remote users/devices and organizational networks. Other mechanisms may include Transport Layer Security (TLS) for securing web-based remote access, Secure Shell (SSH) for command-line access, and other strong encryption protocols. The key is that these mechanisms must be configured and implemented using strong, current cryptographic algorithms that meet government standards, particularly FIPS 140-2 (or newer) validation for modules used to protect CUI.
Does AC.L2-3.1.13 apply to organizations operating outside the United States?
Absolutely. CMMC and NIST SP 800-171 requirements, including AC.L2-3.1.13, apply globally to any organization within the Defense Industrial Base (DIB) that processes, stores, or transmits Controlled Unclassified Information (CUI) on behalf of the U.S. Department of Defense. This includes prime contractors, subcontractors, and their supply chain partners, regardless of their physical location. If your organization handles CUI and utilizes remote access, you must comply with this control, whether your operations are based in North America, Europe, Australia, Asia, or any other international region.
How does Jun Cyber help my organization achieve compliance with AC.L2-3.1.13?
Jun Cyber provides end-to-end support for AC.L2-3.1.13 compliance. We begin with a thorough assessment of your current remote access controls and identify gaps against CMMC Level 2 requirements. Our experts then develop a tailored strategy, assist with the selection and implementation of appropriate cryptographic solutions (e.g., FIPS-validated VPNs, secure TLS configurations), and help establish robust remote access policies and procedures. We also guide you on multi-factor authentication integration, secure configuration baselines, and provide the necessary documentation and evidence to ensure you are fully prepared for your CMMC assessment and maintain ongoing compliance.
What's the difference between confidentiality and integrity in the context of remote access, and which does AC.L2-3.1.13 focus on?
Confidentiality, in the context of remote access, ensures that CUI remains private and is not disclosed to unauthorized individuals during transit. This is typically achieved through encryption, which scrambles the data so only authorized recipients can decrypt and read it. Integrity, on the other hand, ensures that CUI has not been altered or tampered with during transit. This is often achieved through hashing and digital signatures. CMMC AC.L2-3.1.13 specifically focuses on *confidentiality*, mandating the use of cryptographic mechanisms to protect the secrecy of remote access sessions. While integrity is also vital and addressed by other CMMC controls, this particular control zeroes in on preventing unauthorized disclosure.
Are commercial VPNs sufficient for AC.L2-3.1.13 compliance?
In most cases, standard commercial VPNs designed for general consumer use are not sufficient for AC.L2-3.1.13 compliance. The requirement specifies 'cryptographic mechanisms,' and for government data like CUI, this implies FIPS-validated cryptography. Many commercial VPNs may not use FIPS 140-2 validated modules, may lack the necessary security configurations, or may not provide the level of auditability and control required by CMMC. Organizations must use enterprise-grade VPN solutions that incorporate FIPS-validated cryptographic modules and are configured securely according to NIST guidelines to meet this control.
