NSA Robots are "Collecting" Your Data, Too, and They're Getting Away With It
Increasingly, we are watched not by people but by algorithms. Amazon and Netflix track the books we buy and the movies we stream, and suggest other books and movies based on our habits. Google and Facebook watch what we do and what we say, and show us advertisements based on our behavior. Google even modifies our web search results based on our previous behavior. Smartphone navigation apps watch us as we drive, and update suggested route information based on traffic congestion. And the National Security Agency, of course, monitors our phone calls, emails and locations, then uses that information to try to identify terrorists…
Choosing a Secure Password
As insecure as passwords generally are, they’re not going away anytime soon. Every year you have more and more passwords to deal with, and every year they get easier and easier to break. You need a strategy.
The best way to explain how to choose a good password is to explain how they’re broken. The general attack model is what’s known as an offline password-guessing attack. In this scenario, the attacker gets a file of encrypted passwords from somewhere people want to authenticate to. His goal is to turn that encrypted file into unencrypted passwords he can use to authenticate himself. He does this by guessing passwords, and then seeing if they’re correct. He can try guesses as fast as his computer will process them—and he can parallelize the attack—and gets immediate confirmation if he guesses correctly. Yes, there are ways to foil this attack, and that’s why we can still have four-digit PINs on ATM cards, but it’s the correct model for breaking passwords…
It's Time to Break Up the NSA
The NSA has become too big and too powerful. What was supposed to be a single agency with a dual mission—protecting the security of U.S. communications and eavesdropping on the communications of our enemies—has become unbalanced in the post-Cold War, all-terrorism-all-the-time era.
Putting the U.S. Cyber Command, the military’s cyberwar wing, in the same location and under the same commander, expanded the NSA’s power. The result is an agency that prioritizes intelligence gathering over security, and that’s increasingly putting us all at risk…
Let the NSA Keep Hold of the Data
Giving it to private companies will only make privacy intrusion worse.
One of the recommendations by the president’s Review Group on Intelligence and Communications Technologies on reforming the National Security Agency—No. 5, if you’re counting—is that the government should not collect and store telephone metadata. Instead, a private company—either the phone companies themselves or some other third party—should store the metadata and provide it to the government only upon a court order.
This isn’t a new idea. Over the past decade, several countries have enacted mandatory data retention laws, in which companies are required to save Internet or telephony data about customers for a specified period of time, in case the government needs it for an investigation. But does it make sense? In December, Harvard Law professor Jack Goldsmith …
Everything We Know About How the NSA Tracks People's Physical Location
Glenn Greenwald is back reporting about the NSA, now with Pierre Omidyar’s news organization FirstLook and its introductory publication, The Intercept. Writing with national security reporter Jeremy Scahill, his first article covers how the NSA helps target individuals for assassination by drone.
Leaving aside the extensive political implications of the story, the article and the NSA source documents reveal additional information about how the agency’s programs work. From this and other articles, we can now piece together how the NSA tracks individuals in the real world through their actions in cyberspace…
How the NSA Threatens National Security
Secret NSA eavesdropping is still in the news. Details about once secret programs continue to leak. The Director of National Intelligence has recently declassified additional information, and the President’s Review Group has just released its report and recommendations.
With all this going on, it’s easy to become inured to the breadth and depth of the NSA’s activities. But through the disclosures, we’ve learned an enormous amount about the agency’s capabilities, how it is failing to protect us, and what we need to do to regain security in the Information Age…
The Internet of Things Is Wildly Insecure—And Often Unpatchable
We’re at a crisis point now with regard to the security of embedded systems, where computing is embedded into the hardware itself—as with the Internet of Things. These embedded computers are riddled with vulnerabilities, and there’s no good way to patch them.
It’s not unlike what happened in the mid-1990s, when the insecurity of personal computers was reaching crisis levels. Software and operating systems were riddled with security vulnerabilities, and there was no good way to patch them. Companies were trying to keep vulnerabilities secret, and not releasing security updates quickly. And when updates were released, it was hard—if not impossible—to get users to install them. This has changed over the past twenty years, due to a combination of full disclosure—publishing vulnerabilities to force companies to issue patches quicker—and automatic updates: automating the process of installing updates on users’ computers. The results aren’t perfect, but they’re much better than ever before…
"Stalker Economy" Here to Stay
Google recently announced that it would start including individual users’ names and photos in some ads. This means that if you rate some product positively, your friends may see ads for that product with your name and photo attached—without your knowledge or consent. Meanwhile, Facebook is eliminating a feature that allowed people to retain some portions of their anonymity on its website.
These changes come on the heels of Google’s move to explore replacing tracking cookies with something that users have even less control over. Microsoft is …
A Fraying of the Public/Private Surveillance Partnership
The public/private surveillance partnership between the NSA and corporate data collectors is starting to fray. The reason is sunlight. The publicity resulting from the Snowden documents has made companies think twice before allowing the NSA access to their users’ and customers’ data.
Pre-Snowden, there was no downside to cooperating with the NSA. If the NSA asked you for copies of all your Internet traffic, or to put backdoors into your security software, you could assume that your cooperation would forever remain secret. To be fair, not every corporation cooperated willingly. Some fought in court. But it seems that a lot of them, telcos and backbone providers especially, were happy to give the NSA unfettered access to everything. Post-Snowden, this is changing. Now that many companies’ cooperation has become public, they’re facing a PR backlash from customers and users who are upset that their data is flowing to the NSA. And this is costing those companies business…
Leakers and Governments Should Work Together
In the Information Age, it’s easier than ever to steal and publish data. Corporations and governments have to adjust to their secrets being exposed, regularly.
When massive amounts of government documents are leaked, journalists sift through them to determine which pieces of information are newsworthy, and confer with government agencies over what needs to be redacted.
Managing this reality is going to require that governments actively engage with members of the press who receive leaked secrets, helping them secure those secrets—even while being unable to prevent them from publishing. It might seem abhorrent to help those who are seeking to bring your secrets to light, but it’s the best way to ensure that the things that truly need to be secret remain secret, even as everything else becomes public…
