To properly monitor the changes to the web server and the hosted applications, logging must be enabled. Additionally, each record must properly contain the changes made and the names of those who made the changes.
Allowing anonymous users the capability to change the web server or the hosted application will not generate proper log information that can then be used for forensic reporting in the case of a security issue. Allowing anonymous users to make changes will also grant change capabilities to anybody without forcing a user to authenticate before the changes can be made.
This requirement also applies to Zero Trust initiatives.
Check
Review the web server documentation and configuration to determine if anonymous users can make changes to the web server or any applications hosted by the web server.
If anonymous users can make changes, this is a finding.
Fix
Configure the web server to not allow anonymous users to change the web server or any hosted applications.
