Thank you Miroslav. But I still cannot understand the differences between reference policy, target policy or a policy module? furthermore, I installed SElinux on Fedora and the only policy that I can see is available is in directory /etc/selinux/targeted/. By using Fedora 23 Terminal (i.e, dnf install selinux-policy-*******) there are other different policies to install whose names are: (1) "selinux-policy-3.13.1.fc23.noarch" (2)"selinux-policy-devel-3.13.1-152.fc23.noarch" (3)"selinux-policy-doc-3.13.1-152.fc23.noarch" (4)"selinux-policy-minimum-3.13.1-152.fc23.noarch" (5)"selinux-policy-mls-3.13.1-158.11.fc23.noarch" (6)"selinux--policy-sandbox-3.13.1-152.fc23.noarch" (7)" selinux-policy-targeted-3.13.1-158.11.fc23.noarch" What is the difference between this policies(specially between(1) and (7))? using Apol I can load "policy.29" that is in directory /etc/selinux/targeted/. Where are the other policy's file that I can load to Apol and analyse them. -- selinux mailing list selinux@xxxxxxxxxxxxxxxxxxxxxxx http://lists.fedoraproject.org/admin/lists/selinux@xxxxxxxxxxxxxxxxxxxxxxx
