Online banking security is a critical issue over request-response model. But the traditional protection mechanisms are not sufficient to secure the online banking systems that hold information about clients, and banks. The infrastructure of networks, routers, domain name servers, and switches that glue these online banking systems together could be fail, and as a result, online banking systems will no longer be able to communicate accurately or reliably. A number of critical questions arise, such as what exactly the infrastructure is, what threats it must be secured against, and how protection can be provided on a cost-effective basis. But underlying all these questions is how to define secure online banking systems. In this chapter, emerging challenges, security issues and technologies in Online Banking Systems will be analyzed and discussed systematically.
TopWeb History
In the late 1960s, the Advanced Research Projects Agency (ARPA) of U.S. Defense Ministry sponsored a project for implementing the ARPANET, the legacy of Internet. The main purpose of the ARPANET project was to allow multiple users to make request and response messages simultaneously over the same communication channel via phone lines. The information was divided into a number of packets and then routed to their destinations. Each packet consisted of sender address, destination address, additional information for checking the integrity of communication, and part of the data. The communication protocol, which was used in ARPANET project, is called Transmission Control Protocol (TCP). The aim of this protocol is to ensure that the messages are correctly routed from sender to receiver over the communication channel of the ARPANET system (Aljawarneh et. al, 2007; Aljawarneh et. al, 2008).
However, some challenges arose such as how to communicate across a network of networks. ARPANET improved the TCP protocol to be Internet Protocol/Transmission Control Protocol (IP/TCP) protocols. Currently, they are the basic architecture of the Internet (Kumar Bhajantri, Sujatha, Yaligar et al., 2016).
After that, Berners Lee developed World Wide Web (WWW) at the European organization for Nuclear Research in 1990, as well as the concept of hypertext. The WWW is a distributed environment that allows users to communicate and view multimedia-based documents over the Internet. In 1993, web-based services were explored by the Mosaic browser, which had a graphic Interface. Currently, most major web browsers (such as Microsoft Internet Explorer and Netscape Navigator) are used to explore the web-based services (Spinellis, 2016).
