Github user hayssams commented on the pull request: https://github.com/apache/incubator-zeppelin/pull/53#issuecomment-155153646 Hello Jeff Yes websockets are secured. To get added to the user/websocket map, the client must provide the valid ticket. See code below: LOG.info("RECEIVE OP << " + messagereceived.op); LOG.info("RECEIVE PRINCIPAL << " + messagereceived.principal); LOG.info("RECEIVE TICKET << " + messagereceived.ticket); String ticket = TicketContainer.instance.getTicket(messagereceived.principal); if (ticket != null && !ticket.equals(messagereceived.ticket)) throw new Exception("Invalid ticket " + messagereceived.ticket + " != " + ticket); addConnectionToUserSocketMap(conn, messagereceived); Regarding Shiro / SSO, you'll find many integrations around. And yes it may be extended without code change to the Zeppelin code base.
