I am trying to edit source files of GeoServer to meet my project requirements. I want to make newly added OWS services (like "org.geoserver.hello" example) and some of the sub-pages (like "helloweb" example) accessible only for logged-in users.
Is there an example, source file or documentation page (apart from http://docs.geoserver.org/2.7.x/en/user/security/index.html and http://docs.geoserver.org/latest/en/developer/programming-guide/security/index.html) I could rely on?
