Most of the development of online financial services has been reactive, doing the minimum amount of work to try and frustrate the attacks which are observed. It has also been quite piecemeal and uncoordinated. Almost all of the defences have a simple attacker model which only considers those attacks which their prospective target has experienced in the wild. Some of these systems manage to achieve their (fairly limited) goals, but many of them are only partially effective at best. In reaction to the defensive schemes developed by the targets of attacks, many criminals have started to become more sophisticated. This is still lost in the noise of the remarkably. | 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 Rethinking the design of the Internet The end to end arguments vs. the brave new world David D.

Blumenthal Computer Science Telecommunications Bd. mblument@ Version for TPRC submission August 10 2000 Abstract This paper looks at the Internet and the changing set of requirements for the Internet that are emerging as it becomes more commercial more oriented towards the consumer and used for a wider set of purposes. We discuss a set of principles that have guided the design of the Internet called the end to end arguments and we conclude that there is a risk that the range of new requirements now emerging could have the consequence of compromising the Internet s original design principles. Were this to happen the Internet might lose some of its key features in particular its ability to support new and unanticipated applications. We link this possible outcome to a number of trends the rise of new stakeholders in the Internet in particular Internet Service Providers new government interests the changing motivations of the growing user base and the tension between the demand for trustworthy overall operation and the inability to trust the behavior of individual users. Introduction The end to end arguments are a set of design principles that characterize among other things how the Internet has been designed. These principles were first articulated in the early 1980s 2 and they have served as an architectural model in countless design debates for almost 20 years. The end to end arguments concern how application requirements should be met in a system. When a general purpose system for example a network or an operating system is built and specific applications are then built using this system for example e-mail or the World Wide Web over the Internet there is a question of how these specific .
