  1. Re:No on What Would It Take To Have Open CA Authorities? · · Score: 1

    I don't see why you couldn't provide a similar service where you could make the site's self-signed CA cert available before signing into the SSL-encrypted part of the site.

    Well, the problem here is that to securely distribute the CA's public key requires either a trusted network, which could be a company intranet (but for large networks or medium to high security applications isn't secure enough) or sneakernet (delivered by hand). You've apparently chosen one of the above, and it works well for your use.

    However, distributing a CA's public key across the internet so that the recipient knows it's really your key is difficult. The way to do that is use PKI, aka a Trusted Third Party, like Verisign, that has signed your cert or CA.

  2. Re:Not Sure I'm Getting It on Intel Says to Prepare For "Thousands of Cores" · · Score: 4, Interesting

    While prefetching data can be done using a single core, your post in this context gives me a cool idea.

    Who needs branch prediction when you could just have 2 cores running a thread? Send each one executing instructions without a break in the pipeline and sync the wrong core to the correct one once you know the result. You'd still have to wait for results before any store operations, but you should probably know the branch result by then anyway.

  3. Re:Requirement for a signed certificate SSL flaw on When Is a Self-Signed SSL Certificate Acceptable? · · Score: 1

    They should have allowed secure communication without certificates . . .. The problem is that a prerequisite to secure communication the way our current encryption works in an Internet setting is authentication of who you are talking to. Otherwise you don't have end-to-end encryption, which is effectively clear-text communication.

    The authentication comes from the PKI certificates. An encrypted channel is then built upon that trust.

    the danger of an RFID tag in your wallet being randomly sniffed is almost nothing. . . . [they] have an extremely limited range - a couple inches Actually, the range depends almost entirely on the antenna and power of the reader, not the card. You can do a lot more than a couple inches (though the reader will be directional and may need to be aimed).

    It's not until you start working with battery-powered active transmitters (highway EZ-Pass boxes for the fast toll lanes, etc) where there would be a realistic security risk Another example of what I just said, in Atlanta the toll passes are now just the inductive-powered cards, thin paper you stick on your windshield. No card-side power and it's read >70mph. Quite like how someone could read your credit card while you pass by on the interstate.

    Was there any adjustments to the graphics in DooM? I seem to remember settings "High" and "Low". And maybe the ability to have the nose-mounted gun either move around with walking or keep it still. I wouldn't be surprised if I just made that up, though, it was a while ago.

    The other option is why bother? Quite right. Let's do some security analysis.

    Attack vector: Someone sitting in your shop, who has already paid for coffee. Not remote.
    Target compromised: Allows net access, you don't get to charge the guy. No data loss, no availability loss.
    Required knowledge: HTTP and an iPhone number. Barrier could go down with further public exploits.
    Public exploit: Yes, though limited to the geek crowd. And they had to assume this would be true, or they are pretty bad at this.

    For what you're looking at, I think a user-agent string is the kind of security you're looking for when deploying this. There are some scenarios where you would need to escalate security, but IMO not required yet.

  11. Re:Limited impact. on Unicode Encoding Flaw Widespread · · Score: 1

    Relying on content scanning to prevent an exploit to reach an exploitable system is a pretty bad idea, much better to fix the system than the extra layer of defense on the outside. And while this seems good in theory, it is quite possibly the case that the content scanning system has additional logging and reporting functionality that could prove useful either during the attack if preventative actions can be performed by other security products, or it could be extremely useful in a forensic analysis of what has happened and what systems are suspected to be infected by something. Basically, running good code on a machine is helpful in keeping that machine running, but the security industry has had to take a different approach for obvious reasons (there's lots of bad code). So the security they provide is quite different than just stopping an attack at a vulnerability every time. And this exploit avoids that detection and everything that comes along with "security".

    Same thing for me. And bookmarks were broken. I thought I'd lost them, but when I couldn't make any new ones I realized that it just wasn't doing the bookmark thing at all. Running the install a second time cleared up some things for me.

    Also got an error about not having a function in js3250.dll at one point. Reminds me very much of the pre-RC1 releases. Remember those that didn't really handle upgrades without an uninstall and install (and even that was buggy).

    Not only is this cheaper than the book for the class, but it's not required. And probably has more useful information.

    In data structures we used the department head's book. And *gasp* people make money on books! And the way I understand it, it's not that shady since they've been trying to get more of the department to Java and it's one of the few good data structures with Java examples books.

    I've spent money on far worse. Accounts on systems that grade your homework and we only used it twice. Physics departments seem to love those IR remotes that allow for live graded quiz questions, and I've seen "upgrades" that make the old ones not work so that they sell new ones instead of allowing students to buy/sell used. Really, it's funny that someone that seems to be trying to do something good is getting picked on here, when far crazier things are going on.

  19. Events and Pictures, not just relationship status on Facebook Changes Provoke Uproar Among Users · · Score: 1

    Facebook has a feature where you can schedule an event and invite your friends. The college student's version of Outlook meeting requests. People that are going can see who else is going, though it now announces all that data to those people's entire 'social network' whether they requested it or not. This was done retroactively, as well, suddenly making very public knowledge of past occurances. This feed thing is showing me lists of friends that went to recent events. Here's a quote from that page:

    "6 of your friends are attending Queer Television Awards 2006: LGBTQ Welcome Assembly."

    I can click that link and it quickly tells me who those people are. Needless to say, I'm disturbed! All I do is log in, and it's showing me pictures that people have recently uploaded from the crazy parties they were at over the weekend. Sure they put them online so they didn't assume any privacy, but why the hell am I shown this? A lot of these people are just people I've met around campus and they can be my 'facebook friend', and I would otherwise be respecting a certain level of privacy if these things weren't put on my main page by facebook.

    Maybe I'm disturbed because it makes me feel like a stalker?

    Do you realize that files have a concept of "owner", as well as a creation date, and that when you authenticate against the domain, a DC logs that?

    I believe the idea would be to use someone else's workstation. Have the autorun drop the files without making any visible signs of doing anything. Hell, you could probably do this while talking to the person, just ask if you can charge the ipod while you talk (try it, people are agreeable most of the time). Alternatively you could find an unlocked workstation, but what's the fun in that?

    See how easy that was? And note how the large role ipods now play in our lives contributed to the success of this trick.

  25. Re:VOIP calls aren't encrypted? on U.S. Government Issues Report on VoIP Security Holes · · Score: 5, Informative

    CALEA says:

    "ENCRYPTION- A telecommunications carrier shall not be responsible for decrypting, or ensuring the government's ability to decrypt, any communication encrypted by a subscriber or customer, unless the encryption was provided by the carrier and the carrier possesses the information necessary to decrypt the communication."

    Which in my first glance at this means that VoIP can be encrypted, though if the carrier handles too much of the private key generation, which would be necessary for any non-technical user, the carrier must keep the key for law enforcement use. (I'm thinking that a standalone VoIP phone would need a factory generated key on EEPROM, though software VoIP could use your average PC to generate a key itself.) But then again I'm not even sure if this applies to VoIP since this isn't exactly a service I'm currently familiar with. I'll note though that this is the only place "encryption" came up in a search of the law itself, so there's not much more to look at than the above quote. However, what the FBI and FCC have done in regulations may be a totally different matter. Can anyone clear this up more or is it just a regulatory mess?
