Cyberlaw expert Jonathan Zittrain's latest book, The Future of the Internet—And How to Stop It (Yale University Press, 2008; licensed under CC-BY-NC-SA and freely available online), is a thought-provoking analysis of the temptations and dangers inherent in attempts at making the Internet safer by limiting its flexibility and openness. Zittrain holds degrees in both computer science and law, and is a professor of Internet law at Harvard University; he is thus well-versed on both the technical and legal aspects of the Internet. The book convincingly demonstrates that security threats from malware and botnets are increasing at an alarming rate and will soon reach a point where people will feel that "something must be done." But overreaching steps to contain these threats, Zittrain says, might damage the Internet as much as worms and spambots.
The book begins with a history of personal computers and computer networks, comparing them with other technological developments. An interesting analogy is drawn with AT&T, the company which, throughout most of the 20th century, controlled virtually every aspect of telephone services in the United States. AT&T attempted to prohibit any intervention or modification of its system by outside parties, and even waged a long legal battle against the sale of the Hush-A-Phone, a small cup-like device attached to the mouthpiece which purported to prevent bystanders from listening in on the conversation. A court of appeals ultimately allowed the sale of the Hush-A-Phone on the grounds that it did not "affect more than the conversation of the user," but devices which directly interacted with the telephone system were prohibited for many years. Only in 1968 did the FCC rule that proprietary devices could connect to the AT&T network, as long as they did not damage the system. The result was a diversification of the uses of the phone network, with answering machines, faxes and cordless phones entering the mainstream.
