In this case, the sysadmin is provided with a set of questions about the application to be confined, and makes selections based upon patterns which are commonly encountered in similar applications. Some further questions are asked, such as which ports the application might use, and then a loadable policy module is generated.
If you want to try the tool for yourself, you’ll find it in current RHEL 5 and Fedora 7, runnable via system-config-selinux .
