  1. Org structure / priority issues on 80% of .gov Web Sites Miss DNSSEC Deadline · · Score: 1

    IMHO, the reason this isn't done yet is because of the org structure. OMB is responsible for administrative oversight of this type of stuff, but each department don't actually work for them obviously.
    So it could be analagous to the corporate IT department sending an email to each department lead (sales, production) telling them to install certain patches to their desktop PC.

    Yeah sure, the IT department has the right to give direction because the common CEO delegated that responsibility to them, but when prioritizing what is important... they aren't writing the performance review, are they?

    Which is why IT department usually have actual control over such things and push the patches whether the user likes it or not. But OMB doesn't "control" .gov truly.

    Again, just MHO

  2. PKI authentication solves password hell on Analysis of 32 Million Breached Passwords · · Score: 1

    One of the best things the government IT folks have done is the use of the PKI infrastructure. Must have a physical token (smart card) and then an unchanging PIN to access the physical token. The private key never leaves the card itself. And all internal sites are mandated to use that authentication, so no more password hell.
    Yes, the cards expire every couple years, but it's about worn out by then anyways.

    Because Intellectual Property Hoggers International got a patent on a man-in-the-middle (TM) attack and the accountants at the university wouldn't pay the licensing fees, so they had to come up with a COMPLETELY NEW and different attack to avoid patent litigation, thus the incredibly novel "intercept-resend attack" (patent pending).

    All you have to do to do that is jam the control signal. Then it doesn't get any control inputs, and eventually will crash.

    You can do this regardless of whatever encryption may or may not be on the control signal. It's an RF problem, not an encryption problem. (but not as simple of one as it sounds)

    I think you misunderstand what I was getting at.

    What I'm getting at is that -after- some horrible thing occurs (either a mass murder or my hypothetical sex crime), people tend to second guess "funny on-topic vulgarities" and instead point to them and say "see see you should have known".

    I.E. the email made to an Imam asking for marital advice. Now the media is trying to hang government agencies out to dry for not taking action because a US citizen asked someone with a questionable background about marriage advice.

    So in one case, we do nothing, and get raked over the coals, in this case, we do something, and still get raked over the coals.

    So I have a hard time crucifying anyone because we as a society can't set a standard on this type of stuff other than "it doesn't matter what you do because if it doesn't turn out well you're wrong regardless". [By that I mean a public opinion / moral standard, not a legal standard]

  12. Re:Shiny things? on Laser Weapon Shoots Down Airplanes In Test · · Score: 4, Informative

    A couple comments here are focusing on stealth, that's not the big question.

    There is not a single US Gen 2+ stealth aircraft engaged in Iraq/Afghanistan. F-117s have been retired, B-2 are not needed. The aircraft over there are relying on a variety of other IR countermeasures (tactics/flares/directed IR) to defeat threats.

    TFA is talking about shooting down UAVs, which pose a unique problem because they are very small and can be made out of low-tech composite stealth materials like frickin balsa wood. That, combined with a naturally low IR signature because of their low performance envelope, make it hard to target then with traditional guided weapons (IR and Radar guided).

    The key question, which TFA avoided giving details about, is what range they are talking about. If the range is = a 25mm chain gun, this system has little value yet, as if you can find it and track it, a turreted chain gun is already very deadly, the ballistics models aren't that hard to compute. But those weapons are also very easy to fly above.

    If this laser has a range of, say, 8 miles (40,000-ish feet), then things could get interesting. Data that would also be important is how long the laser needs to stay on target, and how small the beam is. If the beam is 1" wide, and must stay on the same spot for 1/2 a second, it could be defeated by old-fashioned 'jinking' which would move the beam around and diffuse the heat. But if it's 1/100 second, then again, it's really deadly.

    Finally (and then I'm done), this laser is really cool, but must be guided by something... at 40,000 feet (or at night), you'll need something better than a Mk 1 eyeball to find and track the target accurately enough, just like you do today, and that's where countermeasures could be applied.

    But a really good EO/IR guidance system that can find/track targets up to 40,000 feet on a clear day at night and a laser that can kill in 1/100" second (or close), and you've got a game-changing technology, forcing aircraft to hope for cloudy days.

  14. Re:I'm dizzy. on VASIMR Ion Engine Could Cut Mars Trip To 39 Days · · Score: 2, Informative

    Another main reason for the length of time involved is the orbital dynamics of the positions of the two planets. There is a astro concept called a Hohmann Transfer (http://en.wikipedia.org/wiki/Hohmann_transfer_orbit), which is a specific impulse efficient way of moving from one orbit to another. But it takes time, and requires waiting until the bodies are in the right position before we do it.

    So you end up having to hang around on Mars for several months.

    Going just a -little- bit faster doesn't gain anything because then you just have to wait longer for the planets to align.

    Since this proposes something vastly quicker, the comment in the article about being able to do it in one planetary pass is what makes the 89 days possible. Requires tons more delta-V to do an orbital transfer this way, but the amount we'd save on human sustainment would more than make up for it.

    Of course, not sure yet about hauling the nuke reactor into space...

    Unfortunately neither of you are really correct.

    Radar is easy to both jam and triangulate, which means radar-guided systems have been quickly taken out. Mobile radar SAMs more difficult, but still not that hard.

    IR guided systems however are very difficult to detect and trace. But a shoulder-launched SAM still requires a visual acquisition to get the lock in the first place, something very hard to do at night. So there are still reasons for flying at night for survivability

    BUT, in Serbia in particular, often the reason for targetting at a certain time had more to do with collatoral damage than survivability. All targets bombed by NATO had to be approved by their legal staff.

    If they tried building another factory/house, you (you are a country, right??) could occupy their territory, imposing martial law, and send to jail any non-combatants that aided the enemy. But you can't just shoot then w/o trial for making ammo them unless they become unlawful combatants (pick up a gun and shoot at you).

    Um, no. That would be called genocide.

    See Law of Armed Conflict (http://en.wikipedia.org/wiki/Law_of_Armed_Conflict) This is actually an aggregate term used to describe legal obligations of many countries who have signed onto a number of treaties.

    Noncombatants cannot be 'indiscriminately' targeted. You can bomb a factory that produces ammunition, but can't just bomb the city to kill everyone in it.

    It's not simple, as technology has changed the application of 'indiscrimate'. WW II bombing targeted industrial areas, and because technology was what it was, killed lots more people. It was as good as could be done (this can be debated, but that's not my point).
    NOW, with GPS smart bombs, a bunch of B-52's carpet bombing Baghdad WWII style would be considered a LOAC violation because it can now be done much more discriminately.

    In fact, factories etc are now often targeted at night so fewer civilian casualties occur.

    From about.com's summary: "Noncombatants may not be made the object of direct attack. They may, however, suffer injury or death incident to a direct attack on a military objective without such an attack violating the LOAC, if such attack is on a lawful target by lawful means"

    So without knowing the business requirement, you can't really say whether a backup strategy is good or bad. Now, in this case, they've recovered all the data in the end, so the backup strategy 'worked' in that it recovered the data, but clearly failed in that it didn't meet the business requirement in a rather shocking fashion.
