Sharepoint 2013 : Security and Policy - SharePoint Security Groups (part 3) - Creating a New Group, Deleting a Group

Site collection administrators may create new custom security groups, and then apply permission levels to these groups within the context of a secured object (site, list, or page). For example, your organization may decide that the default Members, Visitors, and Owners roles are not sufficient and want to create a specialized group of users, called Steering Committee Members. This group might have contributor access to a site in the collection but not delete rights. Look back at the section “Permissions and Permission Levels” for creating a custom permission level that allows contribute without delete. Apply this custom permission level to this custom committee group at the site level (see the next section on granting permissions) to grant this unique set of users the custom permission level. The following steps detail creating the new group as described:

1. Click the gear icon (from the top right of the home page of the site collection).
2. Click Site Settings from the menu.
3. Under the Users and Permissions heading , click the People and Groups link.
4. By default, SharePoint will open a page of the Members group.
5. Click the Groups heading in the left navigation.
6. Click New from the sub-menu.
7. SharePoint displays a page like Figure 4.

8. Give the group a new name and description.
9. Configure the group settings and assign the default permission levels.
10. You do not have to assign default permission levels at this stage; you can do so later when applying permissions to a secured object for users contained in this group.
11. Click the Create button to create the group.
