    "Recently, Lee Brian wrote a great article about her own Linux story in My Dad, Linux and Me. In some of the comments to that article, a discussion of viruses and Linux emerged. While most of the Linux community would agree that viruses are less of an issue in Linux than some other operating systems, there are some people we share files with who are affected by viruses and other malware."

Tools To Password Protect Folder In Linux - LinuxAndUbuntu - 0 views

  •  
    "Most of the time, having a password protected user is all you need to keep your files private and protected from prying eyes. There are those few times when you need to allow access to your account to another person, sometimes there are folders or files you would like to keep away from being accessed. Now we can password protect folder with several handy tools. In the Windows world, these tools are quite easily available for Windows but today we will look at a few options available for the Linux user."

Edward Snowden Explains How To Reclaim Your Privacy - 0 views

  • Micah Lee: What are some operational security practices you think everyone should adopt? Just useful stuff for average people. Edward Snowden: [Opsec] is important even if you’re not worried about the NSA. Because when you think about who the victims of surveillance are, on a day-to-day basis, you’re thinking about people who are in abusive spousal relationships, you’re thinking about people who are concerned about stalkers, you’re thinking about children who are concerned about their parents overhearing things. It’s to reclaim a level of privacy. The first step that anyone could take is to encrypt their phone calls and their text messages. You can do that through the smartphone app Signal, by Open Whisper Systems. It’s free, and you can just download it immediately. And anybody you’re talking to now, their communications, if it’s intercepted, can’t be read by adversaries. [Signal is available for iOS and Android, and, unlike a lot of security tools, is very easy to use.] You should encrypt your hard disk, so that if your computer is stolen the information isn’t obtainable to an adversary — pictures, where you live, where you work, where your kids are, where you go to school. [I’ve written a guide to encrypting your disk on Windows, Mac, and Linux.] Use a password manager. One of the main things that gets people’s private information exposed, not necessarily to the most powerful adversaries, but to the most common ones, are data dumps. Your credentials may be revealed because some service you stopped using in 2007 gets hacked, and your password that you were using for that one site also works for your Gmail account. A password manager allows you to create unique passwords for every site that are unbreakable, but you don’t have the burden of memorizing them. [The password manager KeePassX is free, open source, cross-platform, and never stores anything in the cloud.]
  • The other thing there is two-factor authentication. The value of this is if someone does steal your password, or it’s left or exposed somewhere … [two-factor authentication] allows the provider to send you a secondary means of authentication — a text message or something like that. [If you enable two-factor authentication, an attacker needs both your password as the first factor and a physical device, like your phone, as your second factor, to login to your account. Gmail, Facebook, Twitter, Dropbox, GitHub, Battle.net, and tons of other services all support two-factor authentication.]
  • We should armor ourselves using systems we can rely on every day. This doesn’t need to be an extraordinary lifestyle change. It doesn’t have to be something that is disruptive. It should be invisible, it should be atmospheric, it should be something that happens painlessly, effortlessly. This is why I like apps like Signal, because they’re low friction. It doesn’t require you to re-order your life. It doesn’t require you to change your method of communications. You can use it right now to talk to your friends.

  • Lee: What do you think about Tor? Do you think that everyone should be familiar with it, or do you think that it’s only a use-it-if-you-need-it thing? Snowden: I think Tor is the most important privacy-enhancing technology project being used today. I use Tor personally all the time. We know it works from at least one anecdotal case that’s fairly familiar to most people at this point. That’s not to say that Tor is bulletproof. What Tor does is it provides a measure of security and allows you to disassociate your physical location. … But the basic idea, the concept of Tor that is so valuable, is that it’s run by volunteers. Anyone can create a new node on the network, whether it’s an entry node, a middle router, or an exit point, on the basis of their willingness to accept some risk. The voluntary nature of this network means that it is survivable, it’s resistant, it’s flexible. [Tor Browser is a great way to selectively use Tor to look something up and not leave a trace that you did it. It can also help bypass censorship when you’re on a network where certain sites are blocked. If you want to get more involved, you can volunteer to run your own Tor node, as I do, and support the diversity of the Tor network.]
  • Lee: So that is all stuff that everybody should be doing. What about people who have exceptional threat models, like future intelligence-community whistleblowers, and other people who have nation-state adversaries? Maybe journalists, in some cases, or activists, or people like that? Snowden: So the first answer is that you can’t learn this from a single article. The needs of every individual in a high-risk environment are different. And the capabilities of the adversary are constantly improving. The tooling changes as well. What really matters is to be conscious of the principles of compromise. How can the adversary, in general, gain access to information that is sensitive to you? What kinds of things do you need to protect? Because of course you don’t need to hide everything from the adversary. You don’t need to live a paranoid life, off the grid, in hiding, in the woods in Montana. What we do need to protect are the facts of our activities, our beliefs, and our lives that could be used against us in manners that are contrary to our interests. So when we think about this for whistleblowers, for example, if you witnessed some kind of wrongdoing and you need to reveal this information, and you believe there are people that want to interfere with that, you need to think about how to compartmentalize that.
  • Tell no one who doesn’t need to know. [Lindsay Mills, Snowden’s girlfriend of several years, didn’t know that he had been collecting documents to leak to journalists until she heard about it on the news, like everyone else.] When we talk about whistleblowers and what to do, you want to think about tools for protecting your identity, protecting the existence of the relationship from any type of conventional communication system. You want to use something like SecureDrop, over the Tor network, so there is no connection between the computer that you are using at the time — preferably with a non-persistent operating system like Tails, so you’ve left no forensic trace on the machine you’re using, which hopefully is a disposable machine that you can get rid of afterward, that can’t be found in a raid, that can’t be analyzed or anything like that — so that the only outcome of your operational activities are the stories reported by the journalists. [SecureDrop is a whistleblower submission system. Here is a guide to using The Intercept’s SecureDrop server as safely as possible.]
  • And this is to be sure that whoever has been engaging in this wrongdoing cannot distract from the controversy by pointing to your physical identity. Instead they have to deal with the facts of the controversy rather than the actors that are involved in it. Lee: What about for people who are, like, in a repressive regime and are trying to … Snowden: Use Tor. Lee: Use Tor? Snowden: If you’re not using Tor you’re doing it wrong. Now, there is a counterpoint here where the use of privacy-enhancing technologies in certain areas can actually single you out for additional surveillance through the exercise of repressive measures. This is why it’s so critical for developers who are working on security-enhancing tools to not make their protocols stand out.

Out in the Open: Inside the Operating System Edward Snowden Used to Evade the NSA | Ent... - 0 views

  •  
    TAILS anonymous Operating System- excerpt: "When NSA whistle-blower Edward Snowden first emailed Glenn Greenwald, he insisted on using email encryption software called PGP for all communications. But this month, we learned that Snowden used another technology to keep his communications out of the NSA's prying eyes. It's called Tails. And naturally, nobody knows exactly who created it. Tails is a kind of computer-in-a-box. You install it on a DVD or USB drive, boot up the computer from the drive and, voila, you're pretty close to anonymous on the internet. At its heart, Tails is a version of the Linux operating system optimized for anonymity. It comes with several privacy and encryption tools, most notably Tor, an application that anonymizes a user's internet traffic by routing it through a network of computers run by volunteers around the world. Snowden, Greenwald and their collaborator, documentary film maker Laura Poitras, used it because, by design, Tails doesn't store any data locally. This makes it virtually immune to malicious software, and prevents someone from performing effective forensics on the computer after the fact. That protects both the journalists, and often more importantly, their sources. "The installation and verification has a learning curve to make sure it is installed correctly," Poitras told WIRED by e-mail. "But once the set up is done, I think it is very easy to use." An Operating System for Anonymity Originally developed as a research project by the U.S. Naval Research Laboratory, Tor has been used by a wide range of people who care about online anonymity: everyone from Silk Road drug dealers, to activists, whistleblowers, stalking victims and people who simply like their online privacy. Tails makes it much easier to use Tor and other privacy tools. Once you boot into Tails - which requires no special setup - Tor runs automatically. When you're done using it, you can boot back into your PC's normal operating

Google Redefines Disruption: The "Less Than Free" Business Model - 0 views

  • In the summer of 2007, excitement regarding the criticality of map data (specifically turn-by-turn navigation data) reached a fever pitch.  On July 23, 2007, TomTom, the leading portable GPS device maker, agreed to buy Tele Atlas for US$2.7 billion. Shortly thereafter, on October 1, Nokia agreed to buy NavTeq for a cool US$8.1 billion. Meanwhile Google was still evolving its strategy and no longer wanted to be limited by the terms of its two contracts. As such, they informed Tele Atlas and NavTeq that they wanted to modify their license terms to allow more liberty with respect to syndication and proliferation. NavTeq balked, and in September of 2008 Google quietly dropped NavTeq, moving to just one partner for its core mapping data. Tele Atlas eventually agreed to the term modifications, but perhaps they should have sensed something bigger at play.
  • Rumors abound about just how many cars Google has on the roads building it own turn-by-turn mapping data as well as its unique “Google Streetview” database. Whatever it is, it must be huge. This October 13th, just over one year after dropping NavTeq, the other shoe dropped as well. Google disconnected from Tele Atlas and began to offer maps that were free and clear of either license. These maps are based on a combination of their own data as well as freely available data. Two weeks after this, Google announces free turn-by-turn directions for all Android phones. This couldn’t have been a great day for the deal teams that worked on the respective Tele Atlas and NavTeq acquisitions.
  • Google’s free navigation feature announcement dealt a crushing blow to the GPS stocks. Garmin fell 16%. TomTom fell 21%. Imagine trying to maintain high royalty rates against this strategic move by Google. Android is not only a phone OS, it’s a CE OS. If Ford or BMW want to build an in-dash Android GPS, guess what? Google will give it to them for free.

  • I then asked my friend, “so why would they ever use the Google (non open source) license version.”  (EDIT: One of the commenters below pointed out that all Android is open source, and the Google apps pack, including the GPS, is licensed on top.  Doesn’t change the argument, but wanted the correct data included here.)  Here was the big punch line – because Google will give you ad splits on search if you use that version!  That’s right; Google will pay you to use their mobile OS. I like to call this the “less than free” business model.
  • “Less than free” may not stop with the mobile phone. Google’s CEO Eric Schmidt has been quite outspoken about his support for the Google Chrome OS. And there is no reason to believe that the “less than free” business model will not be used here as well. If Sony or HP or Dell builds a netbook based on Chrome OS, they will make money on every search each user initiates. Google, eager to protect its search share and market volume, will gladly pay the ad splits. Microsoft, who was already forced to lower Windows netbook pricing to fend off Linux, will be dancing with a business model inversion of epic proportion – from “you pay me” to “I pay you.”  It’s really hard to build a compensation package for your sales team on those economics.
