Browser Privacy Test

lazyforker writes "A NYTimes blog post reports the results of security researcher Kate McKinley's tests of various browsers' (FireFox, Chrome, IE, Safari) privacy protection mechanisms. Specifically she tested their cookie handling. She also examined their handling of Flash's cookies. In summary: Safari on Mac OS X (in the 'private browsing' mode) is not so private ('quirky'). Safari on XP is not private at all. Flash behaves awfully everywhere."

      I agree. If the website doesn't bother to serve proper web pages to javascript disabled browsers, then it is not really worth it.

      I'm not sure if that's true when you are using noscript. Certainly for flashblock it isn't true, because the site identifies your browser as being able to run flash.

      In other words, they might have a flash and a non flash version, but they serve you the full flash version cause you *are* flash enabled, just blocked. With noscript you might get a javascript page, even though you block it. Of course that depends on how they implement the degradation of service, some websites will do it right.

      That's apart from the fact that your assume that bad web programming means bad content. That's not the case. If I want to go to a site cause using it is beneficial to me, then I want to use it, whether they have smart or dumb people coding it.

      Here's a couple of easy tips to help maintain a minor level of privacy while browsing:

      - Disable Third-Party cookies (Option under "privacy" tab under Firefox versions >3.0).
      - Add entries to your local hosts file fudging the DNS of known "WebSpy", sorry, I mean "WebAnalytics" domains.

      My current hosts file contains entries similar to the following (but a few more than I list here):

      --- Hosts File Example ---
      127.0.0.1 localhost
      127.0.0.1 www.google-analytics.com
      127.0.0.1 google-analytics.com
      127.0.0.1 ths.news.com.au
      127.0.0.1 adsfac.net
      --- End Hosts File Example ---

      Host File Locations:
      Windows - %SystemRoot%\system32\drivers\etc\hosts
      Most Unixes - /etc/hosts
      Mac OS X - /etc/hosts

      The reason for utilizing the hosts file is to prevent such things as uniquely-generated transparent images (GIFs for instance) being used as inserts in pages to track your browsing in the advent you disable cookies, just add new domains/hosts to the file as you find them.

      In any case, the point is more or less moot, you can minimize your privacy issues, but as any good security professional knows, where there's a will there's a way... and you can be tracked in a number of ways, understanding of how HTTP, DNS and other transfer protocols (also lower-level protocol layers) work will help you minimize your exposure though... if you're concerned, read up on the OSI/ISO network model and how IP and TCP work.

      No, rather, as AC already posted, konqueror will with default associations as shipped by upstream (KDE), using the "view source" function, open pages using kwrite or kate or kedit. Assuming it's not a PEBCAK issue of the local sysadmin or user, OOo at least as shipped by Ubuntu appears to change that default by associating HTML (or possibly XML) files with itself, at a higher priority than kwrite/whatever-else. That's either Ubuntu's fault or OOo's (or the sysadmin/user for overriding the distribution defaults, if that's why the associations are set the way they are), but it certainly isn't KDE/Konqueror's, as KDE isn't what setup those associations, it's just doing what it's supposed to and following the file associations config as setup on the system it's installed on, as overruled by the config of the user running it, if they have chosen to do so.

      Looked at a different way, it would be either OOo's bug, for having a recent documents history that can't be disabled (if that's indeed the case), or a user PEBCAK, for not disabling said history or wiping it out after opening a document they don't wish to appear in said history.

    I like your logic: Aside from a single tile, Columbia's last mission went flawlessly.

    Seriously, though: you've underlined the single greatest problem in computer security today - what we don't see can hurt us. I've written about this at greater length elsewhere, but to put it simply, privacy is the battleground of our decade.

    The struggle to come to terms with privacy will manifest itself in the legal, moral and ethical arenas, but it arises now because of technology and the cavalier approach that the vast majority of people take to it.

    The ramifications of our ability to transmit, access and synthesise vast amounts of data using technology are consistently underestimated by people because of the simple fact that, as far as they're concerned, they are sitting in the relative privacy of their own room with nothing but the computer screen as an intermediary.

    On the consumer side of things, this creates what Schneier calls a Market for Lemons in which the substance of the product becomes less valuable than its appearance. As long as we have the illusion of security, we don't worry about the lack of real protection.

    On the institutional side, we see countless petty abuses of people's privacy. There is nothing stopping a low-level employee from watching this data simply out of prurient interest. In fact, this kind of abuse happens almost every time comprehensive surveillance is conducted. In a famous example, low-level staffers in the US National Security Agency would regularly listen in on romantic conversations between soldiers serving in Iraq and their wives at home. The practice became so common that some even created 'Greatest Hits' compilations of their favourites and shared them with other staffers.

    They would never have done so had the people in question been in the room, but because the experience is intermediated by an impersonal computer screen, which can inflict no retribution on them, their worst instincts get the better of them.

    When discussing software in the 21st Century, we cannot ever treat privacy as just one incidental aspect of a greater system. Privacy defines the system. Starting an argument by throwing it aside in the first subordinate clause gives little weight to any argument that follows.
