Description
The web server must be configured to listen on a specified IP address and port. Without specifying an IP address and port for the web server to use, the web server will listen on all IP addresses available to the hosting server. If the web server has multiple IP addresses, i.e., a management IP address, the web server will also accept connections on the management IP address. Accessing the hosted application through an IP address normally used for non-application functions opens the possibility of user access to resources, utilities, files, ports, and protocols that are protected on the desired application IP address.

Who does this work

5 NICE work roles and 5 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-218748r1043177_chk)

Note: If the server being reviewed is hosting SharePoint, this is Not Applicable. Follow the procedures below for each site hosted on the IIS 10.0 web server: Open the IIS 10.0 Manager. Right-click on the site name under review. Select "Edit Bindings". Verify there are hostname entries and unique IP addresses assigned to port 80 for HTTP and port 443 for HTTPS. Other approved and documented ports may be used. If both hostname entries and unique IP addresses are not configured to port 80 for HTTP and port 443 for HTTPS (or other approved and documented port), this is a finding. Note: If certificate handling is performed at the Proxy/Load Balancer, this is not a finding. Note: If HTTP/Port 80 is not being used, and is not configured as above, this is not a finding. Note: If this IIS 10.0 installation is supporting Microsoft Exchange, and not otherwise hosting any content, this requirement is Not Applicable.
