# Layer Access Control

All Overlay Layers support *Access Control* settings to limit visibility of data to the appropriate group. Open the layer editor to change these settings. Layers may be entirely Public, limited to particular User Groups, or restricted to only Admins. See the [Users and Groups](/seasketch-documentation/administrators-guide/users-and-groups.md) page for details on how to assign users to these different groups and roles.

In addition to assigning *Access Control* rules on individual layers, you can set these permissions on Folders. Visibility of a folder will control access to all contained sub-folders and layers.
