  1. Re:Almost completely useless as a result. on 22 Million SSL Certificates In Use Are Invalid · · Score: 5, Insightful

    How can we ever expect to get any use out of this stuff if we're constantly training the users to ignore everything the security software is trying to tell them?

    We can't, and we shouldn't. When users regularly see warning messages that are abacadabra to many of those users, the effect is predictable (and well understood): user won't read warnings anymore, and just do whatever is most likely to make the warning disappear.

    At that point, you're just wasting user's time, making sure that genuine serious events dive below the radar, and waste system resources / application code (warning dialog boxes, etc) that doesn't get you any real-world gain. Which means that overall, you're doing worse than if you had just silently ignored those warnings.

    If you want secure: make it work, solid, and easy to use. If that's too much to ask, better forget about it - a half-baked feeling of security is worse than being aware of its absence.

    So an obvious better solution would be to handle invalid/broken security tokens for what they are (non-secure), and don't bother users with it other than small (visible) clues that could be checked by users who care and/or know what they're doing. Eg. expired SSL cert in a browser session -> no warning dialog, show URL like regular URLs in address bar (vs. special markup used for secure connections), and open/no lock icon in status bar.

  2. Re:Yet another TLD on ICANN Approves .xxx Suffix For Porn Websites · · Score: 1

    There are too many now, adding even more just dilutes things further and makes it harder for the consumer.

    On the contrary: essentially the domain part of URL's is just a namespace, a 'random' string of Unicode characters. With the TLD part of that namespace having just a 'few' fixed values, that is: using just a small part of all possible codes.

    More TLD's means that on average, that namespace is better utilized. So that on average, shorter domain names can be used to select a specific domain (the extreme being to do away with the concept of TLD's, and allow registration of any domain name). And .xxx would (in general) make it easier to predict the nature of a site's contents, before actually hitting it. Technical limitations aside, that's a win-win from user's point of view.

  6. Doesn't that hold for *all* software? on Struggling To Bridge the Casual-Hardcore Game Gap · · Score: 1

    (..) when I try to play some "advanced" game I find that just learning the rules and controls takes more time than I meant to spend playing the game, so I give up and go back to a simpler game I already know.

    Replace "game" with "application", "operating system", "user interface" or any (non-software) "tool", and IMHO that claim still holds. I hope that software developers realize this; if casual users are to use/enjoy your product, then it:

    • Should preferably not need a manual. Optimal is when everything works so intuitively that there's no point in providing one.
    • Should require zero configuration to perform its basic function. But most importantly:
    • Should have well chosen default settings, set optimal for exactly those casual users. They don't have time to fiddle with settings to get something to work (so will just go off & use something else). 'Hard-core' users will have time to change those defaults into what they want. The other way round doesn't work.

    This is exactly what makes eg. Ubuntu into such a popular Linux distro: throw it on a machine, and most of the time everything works out of the box, and default settings & looks are useable / bearable / easy to understand (or a few important settings are easy to find using the GUI). Linux distro's where this isn't the case can still be good, but because of this not for casual or newbie users. Which cuts potential user group right there.

  7. Re:The nuclear resistance myth on Thailand Shuts Down 43,000 More Websites · · Score: 3, Interesting

    It's a rather weird suggestion as the internet was designed by a government agency.

    Well then perhaps a re-design would be in order since role of the internet has changed dramatically since then.

    Of course that would be impossible in practice - but some new protocols should be possible. Personally I'd wish to see something that integrates (anonymous) P2P-style file sharing with www-style browsing, secure connections between peers, strong authentication, and ease of use. Why? Because that would do away with a lot of ad-hoc solutions like BT, Tor, Freenet, anonymizing proxies, etc, etc, that we have today. None of which are 'perfect' or as easy to use as http protocol.

    Imagine having some source named "XYZ" on the internet, nobody knowing where "XYZ" is located or who it is. You start your browser, and go to 'home page' of XYZ. Then that file is fetched, but not from server somewhere, but from nearest peer (=ordinary user) that also has copy of said file(s). There's some big download on that home page, and when you save it, it gets fetched in BT-style swarming download. All the while using strong authentication that assures you the files you're getting are really from "XYZ" (whomever that may be), and not modified in transit somewhere. With secure connections between peers so that 3rd parties can't see who's getting what, from where.

    With http protocol, someone who produces popular contents is 'punished' for that deed when their hosting server gets pounded. Funding popular sites with advertising has kept the internet mostly free (as in beer). Web hosting companies & mirroring services distribute the load across many websites, P2P programs help with distribution of huge files. But each of those is centralised to some degree, vulnerable to attack, and the fundamental issues remain.

    Sure there would be some problems with such a protocol like database-generated pages, how to determine what's latest version, or how to send data back to original source. But it would be nice to have an integrated fix for above problems that's as easy & transparent to users as ordinary web surfing. Sites like WikiLeaks wouldn't have to worry about funding, torrent sites wouldn't have to move countries to avoid legal attacks, and government blocking wouldn't work. Sure it would make some illegal activities easier, but I think it would still be a net (no pun intended) positive, in the greater scheme of things. And ordinary website owners wouldn't have to worry about costs / diskspace / bandwidth requirements anymore (apart from uploading 1st copy of files).

  11. Software patents will be irrelevant... somehow on Venture Capitalists Lobby Against Software Patents · · Score: 5, Insightful

    My hope is that software patents will be made irrelevant one way or the other... by those countries that don't implement them.

    In effect, it's trying to force a (IMHO: ridiculous) concept onto the rest of the world. Some countries may go along with that, and patent holders (& lawyers!) will profit. But other countries may not, and will be able to do things that would require lots of red tape elsewhere. And thus: be more competitive by ignoring software patents.

    Any type of 'intellectual property' is only a profitable starter if you can get others to go along. But the more you push things into the realm of ridiculous, the fewer people/countries actually will. And when that happens, you have the red tape slowing you down, they don't.

    It means brand new, not yesterday, just found today.

    I think you may be confusing 'found' with 'published'. Until a vulnerability (or an exploit using that vulnerability) is published, there's no way to know for sure it isn't being exploited. The only way to be sure, is if you are doing the exploiting, or you see yourself being exploited. Lacking that, you won't know if a vulnerability exists, and maybe it's being exploited somewhere below the radar. "Zero day" just means that 'being exploited' and 'published' have an overlap in the same 24-hour timeframe.

  14. Re:Current software is fundamentally broken on Adobe Warns of Flash, PDF Zero-Day Attacks · · Score: 1

    Using HTML5 to replace plugins like Flash will in itself do nothing to improve security: right now, those plugins are optional, and if you don't have them installed you have a 'simpler', mature, HTML4-capable browser left. When HTML5 becomes mainstream, that core part of browsers will be even more complex (HTML5 >> HTML4), with fewer optional parts. Or do you think browsers will have a 'disable HTML5 support' somewhere buried in their preferences? (for the sake of simplicity, I'm ignoring whatever HTML5 support may have been built into browsers already).

    Which means (other variables unchanged) that the common, core part of popular browsers will be an even larger attack surface. How this would improve security, is beyond me. Of course the fact that 99% have plugins like Flash installed, and that HTML5 core part of browsers will likely be much better maintained & secured than some of those plugins, will help. But again: in itself it means nothing. And don't forget that adding HTML5 support to browsers, means a lot of new code in the first place. Which all needs to be debugged, tested & fixed over time.

    So the only thing that really helps, is improving the quality of code that goes out the door in the 1st place. And reduce the amount of code that's needed for an average set of functionality. If HTML5 support in browsers helps us do that, I'm all for it. But don't mistake HTML5 for some kind of silver bullet.

    Buzzword or not, "zero day" means a vulnerability that is already being exploited by the time it's published. If vulnerability is published but no exploit exists -> no zero day.

For non-lifethreatening cases, anyone fingered should be able to defend themselves, and a court deciding, before the other party gets private details.
