  1. Critique/Q&A on Jane's Intelligence Review Needs Your Help With Cyberterrorism · · Score: 1

    Overall, I agree with another respondant that the article as written is about
    as informative as an (overly long) abstract. With editting to bring focus to the piece, it
    would be of value as either an introduction to a longer, more technical piece,
    or as an executive overview.

    Introductory paragraphs:
    Author loses focus addressing CBRN and CT issues together. The technical,
    logistical, and organizational hurdles have little in common. At the present
    time, the result of attacks will be far different.

    Modivation:
    Modivational thresholds used for CBRN are crossed quickly if used when planning
    CT attack. An additional threshold may be the perceived lack of punch in a CT
    atttack. In addition, a CT attack leaves a greater likelihood for discovery of
    the source, if it doesn't successfully deal with the number of access logs and other tracing
    methods built into the telecommunications and I.T. systems an attacker must
    work through.

    Organization:
    Setting aside my previous cultural bias, I find that the crucial element
    for successful CT, expertise, seems to be widely available in the
    developing world. Organizations in almost any nation can come in contact with a
    number of trained local programmers and system engineers. By focussing on the
    use of I.T. for normal and secure comm by organizations when planning CBRN attacks, the author may cause
    decision makers to ineffectually concentrate on controlling public access to
    cryptology, rather than on the issues regarding CT attacks themselves.

    Funding:
    Unlike CBRN, little capital is required to obtain and situate a CT "lab" or "labs". Hardware
    is readily available and inexpensive worldwide. The setting can be innocuous. Office automation and software developmenttools and reference works can be had for little cost, even if purchased
    legitimately at retail. The largest potential costs come from connecting
    to a local telecommunications provider. This can be mitigated by a) isolating
    training and rehersal exercises within a closed lab network, and illegally
    tapping into off-site telecom trunk systems where the opportunity presents
    itself, and/or b) state telecom subsidies.

    State Sponsors:
    As with CBRN, a state sponsor can provide telecom advisors with detailed knowledge of typical
    trunking systems. The state can provide ready access to high bandwidth
    connections to the Internet, although this leads to traceability/deniability issues
    after
    executing an attack. The state may provide a more realistic
    training ground, if it allows rehersal attacks within the national I.T. network.

    External Hurdles:
    Given wide disemination of programming and telecom knowledge, and the
    dispersion of expatriot technical professionals, there are few technical
    hurdles to CT, even if the organization that desires CT capability is based in
    an area with few technical resources. The main hurdles would remain perception:
    "does CT do anything for us?"; and security, in that it is more difficult to
    cover one's tracks.

    Q: Using CT, how easy or otherwise is it to bring down or attack vital systems?
    A: This has been addressed elsewhere.
    Q: What sort of skills would be needed to do so, and are they common/teachable?
    A: This requires a more detailed response, which will be posted
    separately.
    Q: Commercial-off-the-shelf software: can it really do CT?
    A: The most common s/w used for attacking I.T. systems is a terminal
    emulator. Value is added by the operator typing into it. An attack
    using a terminal emulator can be automated using the built-in
    programmability of most widely-used operating systems.

    There are a number of s/w packages that are available for free
    download, which are starting to provide COTS ease-of-use with built-in
    CT capabilities. At the moment, the vast majority of these only search
    for or create a security breach in an I.T. system ('Back Orifice',
    'nmap'). An experienced operator is still required to exploit such a breach.
    Q: Which systems are actually attackable?
    A: Any system directly or indirectly connected to a public network can be
    attacked. Any such system is vulnerable to denial of service (can't get
    out or in) attacks or
    spoof (network traffic intercept) attacks. UNIX-based or Windows-based systems
    are most susceptable to penetration attacks because of the large number
    individuals familiar with methods of penetration, which are then widely
    published.
    Q: Can a recovery be made from such attacks?
    A: This has been addressed elsewhere.
    Q: Is it likely to improve/get worse?
    A: This has been addressed elsewhere.
    Q: What sort of preventitive work would you recommend them to carry out?
    A: This has been addressed elsewhere.

  2. Re:So what? on Details About New Trek Series? · · Score: 1

    My gullibility needed an outlet, and it turns out that zoning on Star Trek Rev X.X is a lot cheaper than Scientology.

  3. Re:Who's liable? on Salon.com on Open Source Medical Software · · Score: 1

    I believe that the tort system, as it applies to
    product liability today, has (like medical mal-practice) lost any corrective function it had. Any unfavorable result is assumed to be reasonably preventable, and the participants therefore liable. Yes, it's nice to have someone to kick in the butt, but what's the point?

    Speaking of "COW"s, "it's been done with Solaris, NT, ... " and MacOS, of all things, as shown by the UCLA Appleseed project (http://exodus.physics.ucla.edu/appleseed/applesee d.html).
    Sure, having a manditory GUI slows things down a bit, but if it's not EXERCISED on the majority of processing nodes, then not by much.
