When the Internet Is My Hard Drive, Should I Trust Third Parties?
Wine Therapy is a web bulletin board for serious wine geeks. It’s been active since 2000, and its database of back posts and comments is a wealth of information: tasting notes, restaurant recommendations, stories and so on. Late last year someone hacked the board software, got administrative privileges and deleted the database. There was no backup.
Of course the board’s owner should have been making backups all along, but he has been very sick for the past year and wasn’t able to. And the Internet Archive has been only somewhat helpful.
More and more, information we rely on—either created by us or by others—is out of our control. It’s out there on the internet, on someone else’s website and being cared for by someone else. We use those websites, sometimes daily, and don’t even think about their reliability…
With iPhone, 'Security' Is Code for 'Control'
Buying an iPhone isn’t the same as buying a car or a toaster. Your iPhone comes with a complicated list of rules about what you can and can’t do with it. You can’t install unapproved third-party applications on it. You can’t unlock it and use it with the cellphone carrier of your choice. And Apple is serious about these rules: A software update released in September 2007 erased unauthorized software and—in some cases—rendered unlocked phones unusable.
“Bricked” is the term, and Apple isn’t the least bit apologetic about it.
Computer companies want more control over the products they sell you, and they’re resorting to increasingly draconian security measures to get that control. The reasons are economic…
What Our Top Spy Doesn't Get: Security and Privacy Aren't Opposites
If there’s a debate that sums up post-9/11 politics, it’s security versus privacy. Which is more important? How much privacy are you willing to give up for security? Can we even afford privacy in this age of insecurity? Security versus privacy: It’s the battle of the century, or at least its first decade.
In a Jan. 21 New Yorker article, Director of National Intelligence Michael McConnell discusses a proposed plan to monitor all—that’s right, all—internet communications for security purposes, an idea so extreme that the word “Orwellian” feels too mild…
Steal This Wi-Fi
Whenever I talk or write about my own security setup, the one thing that surprises people—and attracts the most criticism—is the fact that I run an open wireless network at home. There’s no password. There’s no encryption. Anyone with wireless capability who can see my network can use it to access the internet.
To me, it’s basic politeness. Providing internet access to guests is kind of like providing heat and electricity, or a hot cup of tea. But to some observers, it’s both wrong and dangerous.
I’m told that uninvited strangers may sit in their cars in front of my house, and use my network to send spam, eavesdrop on my passwords, and upload and download everything from pirated movies to child pornography. As a result, I risk all sorts of bad things happening to me, from seeing my IP address blacklisted to having the police crash through my door…
Why "Anonymous" Data Sometimes Isn't
Last year, Netflix published 10 million movie rankings by 500,000 customers, as part of a challenge for people to come up with better recommendation systems than the one the company was using. The data was anonymized by removing personal details and replacing names with random numbers, to protect the privacy of the recommenders.
Arvind Narayanan and Vitaly Shmatikov, researchers at the University of Texas at Austin, de-anonymized some of the Netflix data by comparing rankings and timestamps with public information in the Internet Movie Database…
How Does Bruce Schneier Protect His Laptop Data? With His Fists—and PGP
Computer security is hard. Software, computer and network security are all ongoing battles between attacker and defender. And in many cases the attacker has an inherent advantage: He only has to find one network flaw, while the defender has to find and fix every flaw.
Cryptography is an exception. As long as you don’t write your own algorithm, secure encryption is easy. And the defender has an inherent mathematical advantage: Longer keys increase the amount of work the defender has to do linearly, while geometrically increasing the amount of work the attacker has to do…
Did NSA Put a Secret Backdoor in New Encryption Standard?
Random numbers are critical for cryptography: for encryption keys, random authentication challenges, initialization vectors, nonces, key-agreement schemes, generating prime numbers and so on. Break the random-number generator, and most of the time you break the entire security system. Which is why you should worry about a new random-number standard that includes an algorithm that is slow, badly designed and just might contain a backdoor for the National Security Agency.
Generating random numbers isn’t easy, and researchers have discovered lots of …
How We Won the War on Thai Chili Sauce
We’ve opened up a new front on the war on terror. It’s an attack on the unique, the unorthodox, the unexpected. It’s a war on different. If you act different, you might find yourself investigated, questioned and even arrested—even if you did nothing wrong, and had no intention of doing anything wrong.
The problem is a combination of citizen informants and a CYA attitude among police that results in a knee-jerk escalation of reported threats.
This isn’t the way counterterrorism is supposed to work, but it’s happening everywhere. It’s a result of our relentless campaign to convince ordinary citizens that they’re the front line of terrorism defense. “If you see something, say something,” is how the …
Economics, Not Apathy, Exposes Chemical Plants To Danger
It’s not true that no one worries about terrorists attacking chemical plants, it’s just that our politics seem to leave us unable to deal with the threat.
Toxins such as ammonia, chlorine, propane and flammable mixtures are constantly being produced or stored in the United States as a result of legitimate industrial processes. Chlorine gas is particularly toxic; in addition to bombing a plant, someone could hijack a chlorine truck or blow up a railcar. Phosgene is even more dangerous. According to the Environmental Protection Agency, there are…
Gathering "Storm" Superworm Poses Grave Threat to PC Nets
The Storm worm first appeared at the beginning of the year, hiding in e-mail attachments with the subject line: “230 dead as storm batters Europe.” Those who opened the attachment became infected, their computers joining an ever-growing botnet.
Although it’s most commonly called a worm, Storm is really more: a worm, a Trojan horse and a bot all rolled into one. It’s also the most successful example we have of a new breed of worm, and I’ve seen estimates that between 1 million and 50 million computers have been infected worldwide…
