By default, a new portlet inherits the security of the parent folder, but you can change the security of each individual portlet.
If this portlet can be added to My Pages and is not a header, footer, or content canvas portlet, you can force users or groups to include this portlet on their default My Pages. To do so, in the Mandatory drop-down list, click Mandatory.
To specify the type of access a user or group has, in the drop-down list under the Privilege column, select the access type.
For a description of the available privileges, see About Access Privileges.
To delete a user or group, select the user or group and click .
To select or clear all of the user and group check boxes, select or clear the check box to the left of Users/Groups.
To change the column used for sorting or to toggle the sort order between ascending and descending, click the column name.
You see an icon ( or ) to the right of the column name by which the objects are sorted.
If you chose Mandatory for any user or group, in the Mandatory Portlet Priority drop-down list, set this portlet's priority.
The priority determines the portlet's placement on the My Page; portlets with higher priority display closer to the upper-left of the My Page then portlets with lower priority.
