Control story & stream access for each group. This is great if you need certain groups to have access to specific content only.
Manage story/stream access via Groups or Authoring
You can manage group access to stories on the Groups page by selecting the options icon for a specific group and then choosing "Story Access".
Simply add/remove stories that the selected group should have access to.
You can also update story access via the Authoring page by selecting story options and then selecting “Manage Group Access”, i.e. you can add/remove groups who are able to see the story you have selected.
