Finding ID Version Rule ID IA Controls Severity
V-218803 IIST-SV-000132 SV-218803r561041_rule Medium
Description
The separation of user functionality from web server management can be accomplished by moving management functions to a separate IP address or port. To further separate the management functions, separate authentication methods and certificates should be used. By moving the management functionality, the possibility of accidental discovery of the management functions by non-privileged users during hosted application use is minimized.
