# Prevent unauthenticated roleless ACL in scripted ACLs

The **glide.security.allow\_unauth\_roleless\_acl** property controls whether scripted Access Control Lists \(ACLs\) can grant access to unauthenticated users when the ACL is otherwise roleless.

When set to `true`, ACLs containing script may grant access to unauthenticated users. Setting this property to `false` prevents unauthenticated users from accessing resources protected by roleless scripted ACLs.

Confirm that the property **glide.security.allow\_unauth\_roleless\_acl** is set to `false`.
