CMMC Requirement AC.L2-3.1.14 – Remote Access Routing: Route remote access via managed access control points.
This document provides assessment guidance for conducting Cybersecurity Maturity Model Certification (CMMC) assessments for Level 2. Offers actionable guidance on how to map Access Control CMMC Requirements to specific configurations in Microsoft Entra ID (Formerly Azure AD). This NIST special publication provides information on security considerations for several types of remote access solutions. NIST resource that defines the requirements for boundary protection. Video explaining CMMC 2 0 Control AC.L2-3.1.14: Control Remote Access Through Managed Points
Routing remote access through managed access control points enhances explicit, organizational control over such connections, reducing the susceptibility to unauthorized access to organizational systems resulting in the unauthorized disclosure of CUI.
Further Discussion
The OSA can route all remote access through a limited number of remote access control points to reduce the attack surface and simplify network management. This allows for better monitoring and control of the remote connections.
This requirement, AC.L2-3.1.14, limits remote access to specific access control points and complements five other requirements dealing with remote access (AC.L2-3.1.12, AC.L2-3.1.13, AC.L2-3.1.15, IA.L2-3.5.3, and MA.L2-3.7.5):
- AC.L2-3.1.12 requires the control of remote access sessions.
- AC.L2-3.1.13 requires the use of cryptographic mechanisms when enabling remote sessions.
- AC.L2-3.1.15 requires authorization for privileged commands executed during a remote session.
- IA.L2-3.5.3 requires multifactor authentication for network access to non-privileged accounts.
- Finally, MA.L2-3.7.5 requires the addition of multifactor authentication for remote maintenance sessions.
