Discussion [NIST SP 800-171 R2]
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 contractor 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 practice, AC.L2-3.1.14, limits remote access to specific access control points and complements five other practices 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.
