The Internet of Things Will Be the World's Biggest Robot
The Internet of Things is the name given to the computerization of everything in our lives. Already you can buy Internet-enabled thermostats, light bulbs, refrigerators, and cars. Soon everything will be on the Internet: the things we own, the things we interact with in public, autonomous things that interact with each other.
These “things” will have two separate parts. One part will be sensors that collect data about us and our environment. Already our smartphones know our location and, with their onboard accelerometers, track our movements. Things like our thermostats and light bulbs will know who is in the room. Internet-enabled street and highway sensors will know how many people are out and about—and eventually who they are. Sensors will collect environmental data from all over the world…
The Era Of Automatic Facial Recognition And Surveillance Is Here
ID checks were a common response to the terrorist attacks of 9/11, but they’ll soon be obsolete. You won’t have to show your ID, because you’ll be identified automatically. A security camera will capture your face, and it’ll be matched with your name and a whole lot of other information besides. Welcome to the world of automatic facial recognition. Those who have access to databases of identified photos will have the power to identify us. Yes, it’ll enable some amazing personalized services; but it’ll also enable whole new levels of surveillance. The underlying technologies are being developed today, and there are currently no rules limiting their use…
Everyone Wants You To Have Security, But Not From Them
In December Google’s Executive Chairman Eric Schmidt was interviewed at the CATO Institute Surveillance Conference. One of the things he said, after talking about some of the security measures his company has put in place post-Snowden, was: “If you have important information, the safest place to keep it is in Google. And I can assure you that the safest place to not keep it is anywhere else.”
The surprised me, because Google collects all of your information to show you more targeted advertising. Surveillance is the business model of the Internet, and Google is one of the most successful companies at that. To claim that Google protects your privacy better than anyone else is to profoundly misunderstand why Google stores your data for free in the first place…
Our Decreasing Tolerance To Risk
We’re afraid of risk. It’s a normal part of life, but we’re increasingly unwilling to accept it at any level. So we turn to technology to protect us. The problem is that technological security measures aren’t free. They cost money, of course, but they cost other things as well. They often don’t provide the security they advertise, and—paradoxically—they often increase risk somewhere else. This problem is particularly stark when the risk involves another person: crime, terrorism, and so on. While technology has made us much safer against natural risks like accidents and disease, it works less well against man-made risks…
The Vulnerabilities Market and the Future of Security
Brazilian Portuguese translation
Recently, there have been several articles about the new market in zero-day exploits: new and unpatched computer vulnerabilities. It’s not just software companies, who sometimes pay bounties to researchers who alert them of security vulnerabilities so they can fix them. And it’s not only criminal organizations, who pay for vulnerabilities they can exploit. Now there are governments, and companies who sell to governments, who buy vulnerabilities with the intent of keeping them secret so they can exploit them.
The Trouble with Airport Profiling
Why do otherwise rational people think it’s a good idea to profile people at airports? Recently, neuroscientist and best-selling author Sam Harris related a story of an elderly couple being given the twice-over by the TSA, pointed out how these two were obviously not a threat, and recommended that the TSA focus on the actual threat: “Muslims, or anyone who looks like he or she could conceivably be Muslim.”
This is a bad idea. It doesn’t make us any safer—and it actually puts us all at risk.
The right way to look at security is in terms of cost-benefit trade-offs. If adding profiling to airport checkpoints allowed us to detect more threats at a lower cost, than we should implement it. If it didn’t, we’d be foolish to do so. Sometimes profiling works. Consider a sheep in a meadow, happily munching on grass. When he spies a wolf, he’s going to judge that individual wolf based on a bunch of assumptions related to the past behavior of its species. In short, that sheep is going to profile…and then run away. This makes perfect sense, and is why evolution produced sheep—and other animals—that …
The Plan to Quarantine Infected Computers
Keeping infected computers at bay is great in theory, but there are all sorts of complicating factors to consider.
Last month Scott Charney of Microsoft proposed that infected computers be quarantined from the Internet. Using a public health model for Internet security, the idea is that infected computers spreading worms and viruses are a risk to the greater community and thus need to be isolated. Internet service providers would administer the quarantine, and would also clean up and update users’ computers so they could rejoin the greater Internet.
This isn’t a new idea. Already there are products that test computers trying to join private networks, and only allow them access if their security patches are up-to-date and their antivirus software certifies them as clean. Computers denied access are sometimes shunned to a limited-capability sub-network where all they can do is download and install the updates they need to regain access. This sort of system has been used with great success at universities and end-user-device-friendly corporate networks. They’re happy to let you log in with any device you want—this is the consumerization trend in action—as long as your security is up to snuff…
The Story Behind The Stuxnet Virus
Computer security experts are often surprised at which stories get picked up by the mainstream media. Sometimes it makes no sense. Why this particular data breach, vulnerability, or worm and not others? Sometimes it’s obvious. In the case of Stuxnet, there’s a great story.
As the story goes, the Stuxnet worm was designed and released by a government—the U.S. and Israel are the most common suspects—specifically to attack the Bushehr nuclear power plant in Iran. How could anyone not report that? It combines computer attacks, nuclear power, spy agencies and a country that’s a pariah to much of the world. The only problem with the story is that it’s almost entirely speculation…
The Internet: Anonymous Forever
This essay previously appeared in Information Security as the first half of a point-counterpoint with Marcus Ranum. Marcus’s half is here.
Universal identification is portrayed by some as the holy grail of Internet security. Anonymity is bad, the argument goes; and if we abolish it, we can ensure only the proper people have access to their own information. We’ll know who is sending us spam and who is trying to hack into corporate networks. And when there are massive denial-of-service attacks, such as those against Estonia or Georgia or South Korea, we’ll know who was responsible and take action accordingly…
Google And Facebook's Privacy Illusion
These companies and others say privacy erosion is inevitable--but they're making it so.
In January Facebook Chief Executive, Mark Zuckerberg, declared the age of privacy to be over. A month earlier, Google Chief Eric Schmidt expressed a similar sentiment. Add Scott McNealy’s and Larry Ellison’s comments from a few years earlier, and you’ve got a whole lot of tech CEOs proclaiming the death of privacy—especially when it comes to young people.
It’s just not true. People, including the younger generation, still care about privacy. Yes, they’re far more public on the Internet than their parents: writing personal details on Facebook, posting embarrassing photos on Flickr and having intimate conversations on Twitter. But they take steps to protect their privacy and vociferously complain when they feel it violated. They’re not technically sophisticated about privacy and make mistakes all the time, but that’s mostly the fault of companies and Web sites that try to manipulate them for financial gain…
