In order to limit or provide access to make changes throughout the intranet, the Permissions module allows you to assign groups of users to different levels of permissions. Assign groups to ‘Admin global admin permissions’, ‘Module global admin permissions’, ‘Configuration admin permissions’, and ‘Documentation admin permissions’. 

If you want to assign administration rights to a specific module, you can locate the particular module and configure the settings from there. Please see this article to learn more.
