Review the deployment configuration to determine if the web server is sitting behind a proxy server. If the web server is not sitting behind a proxy server, this finding is NA.

If the web server is behind a proxy server, review the documentation and deployment configuration to determine if the web server is configured to generate sufficient information to resolve the source, e.g. source IP, of the logged event and not the proxy server.

Request a user access the hosted application through the proxy server and generate logable events, and then review the logs to determine if the source of the event can be established.

If the source of the event cannot be determined, this is a finding.
