Blown to Bits coverI’ve just finished reading Blown to Bits: Your Life, Liberty, and Happiness After the Digital Explosion, by Hal Abelson, Ken Ledeen, and Harry Lewis, and it’s another title worth adding to your tech policy reading list. The authors survey a broad swath of tech policy territory — privacy, search, encryption, free speech, copyright, spectrum policy — and provide the reader with a wonderful history and technology primer on each topic.

I like the approach and tone they use throughout the book. It is certainly something more than “Internet Policy for Dummies.” It’s more like “Internet Policy for the Educated Layman”: a nice mix of background, policy, and advice. I think Ray Lodato’s Slashdot review gets it generally right in noting that, “Each chapter will alternatively interest you and leave you appalled (and perhaps a little frightened). You will be given the insight to protect yourself a little better, and it provides background for intelligent discussions about the legalities that impact our use of technology.”

Abelson, Ledeen, and Lewis aren’t really seeking to be polemical in this book by advancing a single thesis or worldview. To the extent the book’s chapters are guided by any central theme, it comes in the form of the “two basic morals about technology” they outline in Chapter 1:

The first is that information technology is inherently neither good nor bad — it can be used for good or ill, to free us or to shackle us. Second, new technology brings social change, and change comes with both risks and opportunities. All of us, and all of our public agencies and private institutions, have a say in whether technology will be used for good or ill and whether we will fall prey to its risks or prosper from the opportunities it creates. (p. 14)

Mostly, what they aim to show is that digital technology is reshaping society and, whether we like or it not, we better get used to it — and quick!  “The digital explosion is changing the world as much as printing once did — and some of the changes are catching us unaware, blowing to bits our assumptions about the way the world works… The explosion, and the social disruption that it will create, have barely begun.” (p 3)

In that sense, most chapters discuss how technology and technological change can be both a blessing and a curse, but the authors are generally more optimistic than pessimistic about the impact of the Net and digital technology on our society. What follows is a quick summary of some of the major issues covered in Blown to Bits.

Stuck with limited ISP choices, broadband users are increasingly angry with the growing number of providers that poke around in their customers’ traffic. From resetting Bittorrent sessions to sniffing packets for URLs, more and more providers are wielding their power as the “man in the middle” to monitor and manipulate traffic in unpopular and possibly illegal ways. While these practices can be beneficial, tech-savvy consumers are understandably agitated. Congress is now considering legislation that would outlaw these ISP practices.

Instead of urging lawmakers to enact sweeping new laws that would often do more harm than good, broadband users should look to the recent emergence of commercial secure tunneling services. These services remind us that the marketplace is perfectly capable of resolving skirmishes without government getting involved.

Numerous companies have begun to offer encrypted tunnels using Virtual Private Networks (VPNs). These networks have long been used for a variety of reasons, and are popular with network security experts because of how well they protect data from outside snooping. By tunneling traffic through secure links, broadband users can break free from the constraints imposed by ISPs on certain types of traffic. Routing peer to peer applications through these tunnels makes them almost entirely indistinguishable from other types of traffic—even to stateful packet inspection tools like Sandvine that are undeterred by header encryption.

Tunneling traffic via encrypted, remote servers is also one of the toughest targets for ISPs. Many corporate users and university students connect to VPNs for necessary reasons, and there’s no easy way for an ISP to distinguish “legitimate” VPN traffic from the other kind. And with new secure tunneling firms popping up all the time, simply blocking the IP-address ranges of known tunnels is no solution. Absent a VPN Whitelist—highly infeasible given the growing number of VPNs in the wild—ISPs will soon realize that, no matter how much they invest in packet inspection tools like Sandvine and Phorm, informed users will always find a way to stay a step ahead.
