Our New Regimes of Trust

  • Winter/Spring 2013

Society runs on trust. Over the millennia, we’ve developed a variety of mechanisms to induce trustworthy behavior in society. These range from a sense of guilt when we cheat, to societal disapproval when we lie, to laws that arrest fraudsters, to door locks and burglar alarms that keep thieves out of our homes. They’re complicated and interrelated, but they tend to keep society humming along.

The information age is transforming our sociey. We’re shifting from evolved social systems to deliberately created socio-technical systems. Instead of having conversations in offices, we use Facebook. Instead of meeting friends, we IM. We shop online. We let various companies and governments collect comprehensive dossiers on our movements, our friendships, and our interests. We let others censor what we see and read. I could go on for pages…

Unsafe Security: A Sociologist Aptly Analyzes our Failures in Top-Down Protection

Against Security: How We Go Wrong at Airports, Subways, and Other Sites of Ambiguous Danger, by Harvey Molotch, Princeton University Press, 278 pages, $35.

Security is both a feeling and a reality, and the two are different things. People can feel secure when they’re actually not, and they can be secure even when they believe otherwise.

This discord explains much of what passes for our national discourse on security policy. Security measures often are nothing more than security theater, making people feel safer without actually increasing their protection…

Militarizing Cyberspace Will Do More Harm Than Good

We’re in the early years of a cyberwar arms race. It’s expensive, it’s destabilising and it threatens the very fabric of the internet we use every day. Cyberwar treaties, as imperfect as they might be, are the only way to contain the threat.

If you read the press and listen to government leaders, we’re already in the middle of a cyberwar. By any normal definition of the word ‘war’, this is ridiculous. But the definition of cyberwar has been expanded to include government-sponsored espionage, potential terrorist attacks in cyberspace, large-scale criminal fraud and even hacker kids attacking government networks and critical infrastructure. This definition is being pushed by the military and government contractors, both of which are gaining power and making money from cyberwar fears…

When It Comes to Security, We're Back to Feudalism

Some of us have pledged our allegiance to Google: We have Gmail accounts, we use Google Calendar and Google Docs, and we have Android phones. Others have pledged allegiance to Apple: We have Macintosh laptops, iPhones, and iPads; and we let iCloud automatically synchronize and back up everything. Still others of us let Microsoft do it all. Or we buy our music and e-books from Amazon, which keeps records of what we own and allows downloading to a Kindle, computer, or phone. Some of us have pretty much abandoned e-mail altogether … for Facebook…

Lance Armstrong and the Prisoners' Dilemma of Doping in Professional Sports

  • Bruce Schneier

  • October 26, 2012

Doping in professional sports is back in the news, as the overwhelming evidence against Lance Armstrong led to his being stripped of his seven Tour de France titles and more. But instead of focusing on the issues of performance-enhancing drugs and whether professional athletes be allowed to take them, I’d like to talk about the security and economic aspects of the issue.

Because drug testing is a security issue. Various sports federations around the world do their best to detect illegal doping, and players do their best to evade the tests. It’s a classic security arms race: Improvements in detection technologies lead to improvements in drug detection evasion, which in turn spur the development of better detection capabilities. Right now, it seems drugs are winning; in some places, these drug tests are described as “intelligence tests”—if you can’t get around them, you don’t deserve to play…

Fear Pays the Bills, but Accounts Must Be Settled

A lot of the debate around President Obama’s cybersecurity initiative center on how much of a burden it would be on industry, and how that should be financed. As important as that debate is, it obscures some of the larger issues surrounding cyberwar, cyberterrorism, and cybersecurity in general.

It’s difficult to have any serious policy discussion amongst the fear mongering. Secretary Panetta’s recent comments are just the latest; search the Internet for “cyber 9/11,” “cyber Peal-Harbor,” “cyber Katrina,” or—my favorite—”cyber Armageddon.”

There’s an enormous amount of money and power that results from pushing cyberwar and cyberterrorism: power within the military, the Department of Homeland Security, and the Justice Department; and lucrative government contracts supporting those organizations. As long as cyber remains a prefix that scares, it’ll continue to be used as a bugaboo…

The Importance of Security Engineering

In May, neuroscientist and popular author Sam Harris and I debated the issue of profiling Muslims at airport security. We each wrote essays, then went back and forth on the issue. I don’t recommend reading the entire discussion; we spent 14,000 words talking past each other. But what’s interesting is how our debate illustrates the differences between a security engineer and an intelligent layman. Harris was uninterested in the detailed analysis required to understand a security system and unwilling to accept that security engineering is a specialized discipline with a body of knowledge and relevant expertise. He trusted his intuition…

Drawing the Wrong Lessons from Horrific Events

  • July 31, 2012

Horrific events, such as the massacre in Aurora, can be catalysts for social and political change. Sometimes it seems that they’re the only catalyst; recall how drastically our policies toward terrorism changed after 9/11 despite how moribund they were before.

The problem is that fear can cloud our reasoning, causing us to overreact and to overly focus on the specifics. And the key is to steer our desire for change in that time of fear.

Our brains aren’t very good at probability and risk analysis. We tend to exaggerate spectacular, strange and rare events, and downplay ordinary, familiar and common ones. We think rare risks are more common than they are. We fear them more than probability indicates we should…

So You Want to Be a Security Expert

  • July 12, 2012

This essay orginally appeared as part of a series of advice columns on how to break into the field of security.

I regularly receive e-mail from people who want advice on how to learn more about computer security, either as a course of study in college or as an IT person considering it as a career choice.

First, know that there are many subspecialties in computer security. You can be an expert in keeping systems from being hacked, or in creating unhackable software. You can be an expert in finding security problems in software, or in networks. You can be an expert in viruses, or policies, or cryptography. There are many, many opportunities for many different skill sets. You don’t have to be a coder to be a security expert…

Securing Medical Research: A Cybersecurity Point of View

  • June 22, 2012

ABSTRACT: The problem of securing biological research data is a difficult and complicated one. Our ability to secure data on computers is not robust enough to ensure the security of existing data sets. Lessons from cryptography illustrate that neither secrecy measures, such as deleting technical details, nor national solutions, such as export controls, will work.


Science and Nature have each published papers on the H5N1 virus in humans after considerable debate about whether the research results in those papers could help terrorists create a bioweapon (…
