rqlite supports a few levels security, which you can use separately or together.

You can enable BasicAuth on the HTTP endpoints. You can also require that any client presenting BasicAuth credentials has the right permission for the operation the client is trying to perform. Finally you can also enable Mutual TLS, requiring that any client that connects must first present a cert that is signed by an acceptable CA.
