I installed jenkins on a CentOS system. Now I am able to open the jenkins web page on localhost:8080. I want to add a login required for accessing this url. I enabled security on 'Configure Global Security' page then set 'Unix user/group database' under 'Security Realm'. In Authorization part, I set 'Logged-in users can do anything'. By doing this configuration, only logged in user can do build and modification on jobs. But there is a problem that users can still read all the jobs information without log in. How can I prevent anonymous users to access my jenkins web page?
