Datasets on Socrata-powered datasites can be set to either public or private. Public datasets are accessible to all visitors of your datasite, and can be discovered through the site-wide data catalog. Private datasets can only be accessed by the dataset owner, users on their datasite with "Publisher" rights or higher, or users with whom they've created a share with using the Sharing tool.

To change the permissions on your dataset, click on the "Manage" button to open the Edit sidebar, then click on "Permissions". Where it says "This dataset is currently public" or "This dataset is currently private", check the box next to your desired permission option in the box below. Click "Update" to save your changes and close the sidebar.

To share a dataset, click manage --> sharing --> enter an email address --> share.

It may take up to 15 minutes for your dataset to be re-indexed and for the site-wide data catalog to be updated. The actual permissions change, however, occurs immediately.
