    I was just having a discussion with a good friend 2 nights ago when she said "When I registered to vote I registered as an independent because I wasn't sure if I agreed with the democrats or republicans more, but after seeing some of the stuff Gore has said I've decided to become a republican."

    This came from someone who I know doesn't side with alot of the republican beliefs either. I tried telling her to check out other parties and she said she would, but it seemed more like she was just humoring me.

    HOWEVER, Linux is missing (or semi-missing) several pieces to make it an excellent gaming platform: easy to install/configure high-end graphics and, of course, DVD.

My grandmother just bought a TiVo (which also runs linux) and had it set up and working in half an hour! This coming from someone who doesn't understand a thing about her computer. I would hope a gaming console would abstract 99.9% of what's underneath the hood from the user in the same way.

    As for high-end graphics, from what I've seen it does high end graphics just as well as Windows, but I'm no expert, so I'll just avoid this one... :-)

    And last, DVD. Linux can read from DVD's and can even play the video from them, the only problem right now is getting around CSS (their encryption/scrambling system) Other than that DVD's are just a huge CD, and manufacturers have been putting games on CD's for years.

    Tom Van Vleck

    About 1976, I was explaining Multics security to a colleague at Honeywell. (This was before it got the B2 rating, but the mandatory access control mechanism was present.) I explained the difference between storage channels and timing channels, and said that timing channels weren't weren't important because they were so slow, noisy, and easily clogged, that you couldn't send a signal effectively.

    My friend, Bob Mullen, astounded me a few days later by showing me two processes in the terminal room. You could type into one and the other would type out the same phrase a few seconds later. The processes were communicating at teletype speed by causing page faults and observing how long they took. The sender process read or didn't read certain pages of a public library file. The receiver process read the pages and determined whether they were already in core by seeing if the read took a long or short real time. The processes were running on a large Multics utility installation at MIT under average load; occasionally the primitive coding scheme used would lose sync and the receiver would type an X instead of the letter sent. If you typed in "trojan horse," the other process would type "trojan horse" a little later, with occasional X's sprinkled in the output.

    Bob pointed out that noise in the channel was irrelevant to the bandwidth (Shannon's Law). Suitable coding schemes could get comparable signalling rates over many different resource types, despite countermeasures by the OS: besides page faulting, one could signal via CPU demand, segment activation, disk cache loading, or other means.

    When I thought about this I realized that any dynamically shared resource is a channel. If a process sees any different result due to another process's operation, there is a channel between them. If a resource is shared between two processes, such that one process might wait or not depending on the other's action, then the wait can be observed and there is a timing channel.

    Closing the channel Bob demonstrated would be difficult. The virtual memory machinery would have to do extra bookkeeping and extra page reads. To close the CPU demand channel, the scheduler would have to preallocate time slots to higher levels, and idle instead of making unneeded CPU time available to lower levels.

    Bob and I did not compute the bandwidth of the page fault channel. It was about as fast as electronic mail for short messages. A spy could create a Trojan Horse program that communicated with his receiver process, and if executed by a user of another classification, the program could send messages via timing channels despite the star-property controls on data.

    The rules against writing down were designed to keep Trojan Horse programs from sending data to lower levels, by ensuring that illegal actions would fault. In this case, the sender is doing something legal, looking at data he's allowed to, consuming resources or not, and so on. The receiver is doing something legal too, for example looking at pages and reading the clock. Forbidding repeated clock reading or returning fake clock values would restrict program semantics and introduce complexity.

    I believe we need a mechanism complementary to the PERMISSION mechanism, called a CERTIFICATION mechanism. This controls the right to Execute software, while permission controls the Read and Write flags. A user classified Secret is not allowed to execute, at Secret level, a program certified only to Unclassified. Programs would only be certified to a given level after examination to ensure they contained no Trojan Horses. This kind of permission bit handling is easy to implement, and if the site only certifies benign programs, all works perfectly.

    How do we examine programs to make sure they have no Trojan Horses? The same way we examine kernels to make sure they don't. Examining application code to ensure it doesn't signal information illegally should be easier than the work we have to do on a kernel.

    Do we need to forbid write down for storage, if we allow write down via timing channels? It's inconsistent to forbid some write down paths and allow others. The main reason for preventing write down is not to stop deliberate declassification (a spy can always memorize a secret and type it into an unclassified file), it's to protect users from Trojan Horse programs leaking information. The certification approach solves this problem adifferent way, by providing a way to prevent execution of Trojan Horse programs.

    Who should be allowed to certify a program to a given level? I think anyone who can create a program to execute at level X should be able to take a lower level program and certify it to level X. We can't stop a malicious user from creating a transmitter program, unless we forbid all program creation at level X. Other policies are possible; a site could centralize all program certification as a security officer responsibility. In any case, the OS should audit every certification and store the identity of the certifier as a file attribute.

    Part III Investigation of Protected Electronic Data

    The spooks' charter. Here any policeman could show up with some encrypted data and an order to provide the decryption key. If you refuse you go to jail for 2 years. Usually they won't need a judicial warrant; sometimes they won't need any sort of warrant at all, just their say-so.

    The problem is that if you don't actually have they key it is up to you to prove that. If you deleted it, or if you never actually had it, you're in trouble. If the authorities reckon you've got it stashed on a floppy buried in the flowerbeds at Hyde Park Corner, go directly to jail, do not pass Go, do not collect £200.

    How can you prove you don't have something? Try slapping your forehead in a manner likely to convince the judge.

    The other new power here is that the authorities can order you to keep the disclosure of your key a secret. If you tell anyone at all you'll be going down for up to 5 years for "tipping off". Not only is this disasterous for information security, but it even stops you complaining about unfair treatment. Toddle off to court to demand judicial review of the order to disclose and all you'll get from the Judge is an extended stay in Her Majesty's finest accomodation because telling the judge is illegal!. There is a tame Tribunal to hear complaints and cover them up; you aren't even entitled to legal representation at it.

    STAND says, poetically: How does Part III breach the Human Rights Act, let me count the ways... Unfair offences, reversal of burden of proof, defences that are logically impossible to prove, a wholly inadequate complaints procedure with no appeals, unneccesarily broad powers, potential to force you to incriminate yourself, the list goes on.

    The police need something to help them to decrypt data in certain circumstances (and not in others). Part III is not it. Parliament should delete this Part and try to come up with something better when it replays the Interception of Communications Act next year. If it doesn't throw this Part out, the European Court of Human Rights will.

    I will probably be flamed for this, but I have found NT to be _very_ stable for me as long as the hardware is stable. The key is to use quality hardware that isn't running on beta quality drivers. Most of my problems have come from either using no-brand hardware (you get what you pay for) or using the latest greatest thing with driver version 1.0.1. NT drivers don't seem to come out of the Beta phase until they've hit 2.0 or so.I am not of course speaking for the security of NT in any way, and I have seen problems like you mentioned about memory being maxed out after a while. What I am trying to say is that in 2 years of administrating a network I have seen that 99% of the instability of NT comes from beta quality drivers. In fact after tracking down all the crappy hardware and drivers on the problematic machines we've averaged less than 1 BSOD a month total for 25 computers. (I know, I know... Linux may crash less than that, but that's not to shabby for what I was given to work with ;-))
