# Require authentication by default for client-callable script includes

By default, client-callable script includes that do not explicitly set visibility, are public. If needed, add the **glide.script.ccsi.ispublic** property to enable privacy control over all client-callable script includes accessed by public pages.

The **glide.script.ccsi.ispublic** system property makes sure that client-callable script-includes, also known as Ajax script includes, are not automatically made available to non-authenticated users. If **glide.script.ccsi.ispublic** is not set to the recommended value of **false**, then it allows script includes to be run as public scripts and grant unauthenticated users access to instance data.

Ensure that the property **glide.script.ccsi.ispublic** is set to **false**.

**Warning:** This is a safe harbor property, meaning the value can't be altered once it's changed. It is non-revertible.

Functional impact

</td><td>

If the client-callable script includes are designated as public \(that is, this property is missing\), then unauthenticated users can execute client scripts. Add the property restricts the execution of scripts by a non-logged-in user.
