NSA Surveillance: a Guide to Staying Secure

The NSA has huge capabilities – and if it wants in to your computer, it's in. With that in mind, here are five ways to stay safe

Now that we have enough details about how the NSA eavesdrops on the internet, including today’s disclosures of the NSA’s deliberate weakening of cryptographic systems, we can finally start to figure out how to protect ourselves.

For the past two weeks, I have been working with the Guardian on NSA stories, and have read hundreds of top-secret NSA documents provided by whistleblower Edward Snowden. I wasn’t part of today’s story—it was in process well before I showed up—but everything I read confirms what the Guardian is reporting.

At this point, I feel I can provide some advice for keeping secure against such an adversary…

The US Government Has Betrayed the Internet. We Need to Take It Back

The NSA has undermined a fundamental social contract. We engineers built the internet – and now we have to fix it

German translation

Government and industry have betrayed the internet, and us.

By subverting the internet at every level to make it a vast, multi-layered and robust surveillance platform, the NSA has undermined a fundamental social contract. The companies that build and manage our internet infrastructure, the companies that create and sell us our hardware and software, or the companies that host our data: we can no longer trust them to be ethical internet stewards.

This is not the internet the world needs, or the internet its creators envisioned. We need to take it back…

Italian translation

Imagine the government passed a law requiring all citizens to carry a tracking device. Such a law would immediately be found unconstitutional. Yet we all carry mobile phones.

If the National Security Agency required us to notify it whenever we made a new friend, the nation would rebel. Yet we notify Facebook Inc. (FB) If the Federal Bureau of Investigation demanded copies of all our conversations and correspondence, it would be laughed at. Yet we provide copies of our e-mail to …

Will Giving the Internet Eyes and Ears Mean the End of Privacy?

  • Bruce Schneier

  • May 16, 2013

The internet has turned into a massive surveillance tool. We’re constantly monitored on the internet by hundreds of companies—both familiar and unfamiliar. Everything we do there is recorded, collected, and collated—sometimes by corporations wanting to sell us stuff and sometimes by governments wanting to keep an eye on us.

Ephemeral conversation is over. Wholesale surveillance is the norm. Maintaining privacy from these powerful entities is basically impossible, and any illusion of privacy we maintain is based either on ignorance or on our unwillingness to accept what’s really going on…

The Meaning of Trust

Security technologist and author Bruce Schneier looks at the age-old problem of insider threat

Rajendrasinh Makwana was a UNIX contractor for Fannie Mae. On October 24, he was fired. Before he left, he slipped a logic bomb into the organisation’s network. The bomb would have “detonated” on January 31. It was programmed to disable access to the server on which it was running, block any network monitoring software, systematically and irretrievably erase everything, and then replicate itself on all 4,000 Fannie Mae servers. Court papers claim the damage would have been in the millions of dollars.

Luckily, another programmer discovered the script a week later, and disabled it…

Virus and Protocol Scares Happen Every Day — But Don't Let Them Worry You

An SSL security flaw got bloggers hot and bothered, but it's the vendors who need to take action

  • December 9, 2009

Last month, researchers found a security flaw in the SSL protocol, which is used to protect sensitive web data. The protocol is used for online commerce, webmail, and social networking sites. Basically, hackers could hijack an SSL session and execute commands without the knowledge of either the client or the server. The list of affected products is enormous.

If this sounds serious to you, you’re right. It is serious. Given that, what should you do now? Should you not use SSL until it’s fixed, and only pay for internet purchases over the phone? Should you download some kind of protection? Should you take some other remedial action? What?…

Reputation is Everything in IT Security

  • November 11, 2009

In the past, our relationship with our computers was technical. We cared what CPU they had and what software they ran. We understood our networks and how they worked. We were experts, or we depended on someone else for expertise. And security was part of that expertise.

This is changing. We access our email via the web, from any computer or from our phones. We use Facebook, Google Docs, even our corporate networks, regardless of hardware or network. We, especially the younger of us, no longer care about the technical details. Computing is infrastructure; it’s a commodity. It’s less about products and more about services; we simply expect it to work, like telephone service or electricity or a transportation network…

Why Framing Your Enemies Is Now Virtually Child's Play

In the eternal arms race between bad guys and those who police them, automated systems can have perverse effects

A few years ago, a company began to sell a liquid with identification codes suspended in it. The idea was that you would paint it on your stuff as proof of ownership. I commented that I would paint it on someone else’s stuff, then call the police.

I was reminded of this recently when a group of Israeli scientists demonstrated that it’s possible to fabricate DNA evidence. So now, instead of leaving your own DNA at a crime scene, you can leave fabricated DNA. And it isn’t even necessary to fabricate. In Charlie Stross’s novel Halting State, the bad guys foul a crime scene by blowing around the contents of a vacuum cleaner bag, containing the DNA of dozens, if not hundreds, of people…

The Battle Is On Against Facebook and Co to Regain Control of Our Files

Our use of social networking, as well as iPhones and Kindles, relinquishes control of how we delete files -- we need that back

  • September 9, 2009

File deletion is all about control. This used to not be an issue. Your data was on your computer, and you decided when and how to delete a file. You could use the delete function if you didn’t care about whether the file could be recovered or not, and a file erase program — I use BCWipe for Windows — if you wanted to ensure no one could ever recover the file.

As we move more of our data onto cloud computing platforms such as Gmail and Facebook, and closed proprietary platforms such as the Kindle and the iPhone deleting data is much harder.

You have to trust that these companies will delete your data when you ask them to, but they’re …

People Understand Risks — But Do Security Staff Understand People?

Natural human risk intuition deserves respect -- even when it doesn't help the security team

This essay also appeared in The Sydney Morning Herald, and The Age.

People have a natural intuition about risk, and in many ways it’s very good. It fails at times due to a variety of cognitive biases, but for normal risks that people regularly encounter, it works surprisingly well: often better than we give it credit for.

This struck me as I listened to yet another conference presenter complaining about security awareness training. He was talking about the difficulty of getting employees at his company to actually follow his security policies: encrypting data on memory sticks, not sharing passwords, not logging in from untrusted wireless networks. “We have to make people understand the risks,” he said…
