The application server must adhere to the principles of least functionality by providing only essential capabilities.

Application servers provide a myriad of differing processes, features and functionalities. Some of these processes may be deemed to be unnecessary or too unsecure to run on a production DoW system. Application servers must provide the capability to disable or deactivate functionality and services that are deemed to be non-essential to the server mission or can adversely impact server performance, for example, disabling dynamic JSP reloading on production application servers as a best practice.

Review the application server documentation and configuration to determine if the application server can disable non-essential features and capabilities.

If the application server is not configured to meet this requirement, this is a finding.

Configure the application server to use only essential features and capabilities.
