Administrators often criticize Security Enhanced Linux (SELinux) policies for being too complex, and they have a point. Mandatory access control-based administration is tedious and easy to misconfigure.
It can be tough to handle the extended security attributes across a range of users, processes and files or directories that encompass more than one server. Novell addresses this problem in its enterprise-class server offerings with the AppArmor suite of policy management applications, but nothing comparable exists yet for systems management in Red Hat enterprise servers (or CentOS derivatives).

Seedit offers a suite of native front-end administration utilities.

Seedit provides a control panel with icons that correspond to status, management, policy generation, policy editing and policy application or re-labeling actions.Read Full Story
