This study overviews the WebSocket protocol and the API, and describes the advantages they provide. The main contribution of this paper is to review and analyze the security concerns related to WebSockets, discuss the possible solutions and provide the best practices for deployment of a WebSocket service. Also, this paper proposes that certain security features should be implemented in web browsers to ensure the security and the privacy of the users. Web browser vendors are in important role when implementing the security features. The WebSocket technology is not yet standardized but it is expected that usage of WebSockets will increase signiﬁcantly in the near future. Overall, WebSockets solve connectivity problems, not the security problems. Several open issues exist, but with a good design and proper implementation of web browsers and web services, the risk level can be mitigated.  \nKEYWORDS: websocket, html5, security, browser security, javascript, web  \n1 Introduction  \nWebSocket is a technology that provides a bi-directional real-time communications channel over a Transmission Control Protocol (TCP) connection [3] . The WebSocket technology covers JavaScript API (Application Programming Interface) that is speciﬁed by World Wide Web Consortium (W3C), and a protocol that is speciﬁed by Internet Engineering Task Force (IETF) [5] . The status of the latest speciﬁcation is a “proposed standard”1. WebSocket API is often denoted as HTML5 WebSocket API, although it is actually separated from the HTML5 speciﬁcation and is currently being developed and speciﬁed independently [17] . The Candidate Recommendation of the WebSocket API was released on September 2012, hence the API is not yet standardized. However, the functionality speciﬁed in the latest drafts is already implemented in various web browsers.  \nThe WebSocket protocol is a network protocol running on TCP. It is designed to be implemented in web browsers and web servers but it can be used for other purposes as well. The WebSocket protocol is independent of HyperText Transfer Protocol ([HTTP](HTTP)), although the protocols have similarities such as using TCP port 80 and the handshake process when  \n1[http://www.rfc-editor.org/info/rfc6455](http://www.rfc-editor.org/info/rfc6455)  \ninitializing a connection [2] . Because the WebSocket technology is expected to inﬂuence the communications in the web during the next few years, WebSockets may in turn inﬂuence the security of the web. WebSocket is still a relatively new concept and not much public research has been done in the ﬁeld of WebSocket security. This paper focuses on the possible security concerns in the WebSocket protocol and the API, and also on the security features the technology provides.  \nThis paper is structured as follows. The second chapter reviews the background of WebSocket technology and the usage of the JavaScript API. The third chapter focuses on the technical security issues of WebSockets. The fourth chapter discusses and analyzes the security concerns and potential solutions. The ﬁfth chapter proposes a few solutions on how the security of WebSockets could be improved. The ﬁnal chapter concludes the whole paper and outlines the future work.  \n2 Background  \nThis chapter reviews the WebSocket technology in more detail. Section 2.1 discusses the new features and advantages of the technology compared to traditional web communications. Section 2.2 illustrates the usage of the WebSocket JavaScript API on client side.  \n2.1 Features and advantages of WebSockets  \nThe main difference in WebSockets – compared to the usual network trafﬁc over [HTTP](HTTP) – is that the WebSocket protocol does not follow the traditional request-response convention [16] .
