Discussion:

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.

Upon assessment, assessors must determine if-

3.1.14[a] managed access control points are identified and implemented.
3.1.14[b] remote access is routed through managed network access control points.
