  1. Re:Privilege level on New Windows Vulnerability in Help System · · Score: 4, Insightful

    "could allow an attacker to execute arbitrary code with the privileges of the user running IE" This is why you run as a restricted user rather than administrator or power user. Restricted users don't have write or modify permissions to the WINNT or Program Files directories or subdirectories. And they certainly don't have permission to screw with the registry.

    Even a user without admin privileges can turn the box into a spam relay (or a DDoS agent), so reducing privileges is only a very partial solution.

    There was even a worm which exploited the vulnerability behind the last item on that list.

    The problem with Apache vs. IIS comparisons is that they are hardly fair. IIS comes with tons of dangerous examples and extensions. Bugs in widespread Apache modules are usually not attributed to Apache itself. There's nothing wrong with that, but it doesn't give you much information which web server, when configured properly, is more secure.

  3. Capture flow data on What Network Sniffing Tools Do You Use? · · Score: 1

    We mainly use Cisco Netflow Data Export to detect and analyze network anomalities. If your router doesn't support netflow export, you might be able to hook a PC to switch at a monitor port and use some tool like fprobe or nProbe to generate flow data.

    A short-term archive of flow data is extremely useful for handling all kinds of abuse complaints (did you know that a significant portion is forged?) and detecting worms, outgoing DoS attacks etc. on your own network.

  4. Re:Researchers are Paying Their Own Way on AT&T Labs' Brain Drain · · Score: 1

    Honestly, researcher communities (especially the academic ones) are disdainful to the "achievements" of "industrial research". The reject rates on industrial papers have been pretty high (usually more than 50%). This is because that the "innovations" of industrial "research" are more or less either one or some of the following: rehashing old ideas, implementing old ideas with new looks / new aspects / into new problems which often not worth mentioning, combining several old ideas in some obvious ways.

    Don't forget that often, there is no need (or time) to write a paper. For example, in the area of transaction processing, a lot of research went directly into commercial products, and quite a few of the underlying principles were only rediscovered in academia.

  5. Re:I'm TRULY not attempting to Troll on PhatBot Trojan Spreading Rapidly On Windows PCs · · Score: 1

    But I'm getting so tired of these virus 'alerts' constantly bombarding me day in and day out!

    I tend to agree. Most of these alerts turn out to be unfounded, and important developments are not announced at all. What about the first Beagle/Bagle wave, for example?

    If you are responsible for insecurity on some organization's network, you should gather as much statistics as you can, and get involved in some of the trust-based communities that deal with security. Try to share your observations and knowledge with like-minded people. FIRST or your regional FIRST look-alike could be a good start (if they still actively engage in such discussions).

    Statistics and discussions with peers enable you to predict the impact of new developments to some degree. A threat meter at 9.6 doesn't help at all, and press reports written after seeing such alerts don't do it, either.

    (Yeah, the 9.6 is purely fictional, I haven't seen the DHS report that leaked to the Washington Post and don't even know if the DHS is now involved in the botnet rating business.)

    I haven't got the exact figures, but I reckon 99% of all code written out there must be written in Imperative (sometimes pseudo OO) languages.

    There are lots of applications implemented in Excel spreadsheets. The stuff some people (who consider themselves non-programmers) do with Excel (or any other spreadsheet) is just amazing.

    Excel is a bit limited (especially if you don't use VBA), but it's certainly some form of functional, purely applicative programming.

    I disagree -- there's lots of demand for Failover, especially at small/medium sites that don't want to deal with the clustering business.

    Some users have SQL databases which just support their business. You seem to have users in mind whose businesses are their SQL databases (or at least they think it is, usually it's your brand or your customer, depending on your perspective).

    I'm not saying that nobody needs failover, I'm only reporting my observation that quite a few proprietary database users only use a tiny subset of the functionality. Adding more functionality won't change this. 8-)

  8. Re:Yukon's promised features on New SQL Server Release Slips to 2005 · · Score: 3, Insightful

    Yukon is finally going to deliver online restoration, database mirroring with automatic failover, and support for mirrored backup sets.

    Let's face it, these features isn't something most users need. If Microsoft sees real trouble, they will simply slash the per-processor license cost by a factor of 50 or 100, and switching suddenly becomes a non-issue for most users.

    Per-client licenses and awfully high per-processor licensing costs are the most important factor which motivates most users to attempt other solutions. Of course, the proprietary databases have important features which look very good on paper, but I've seen quite a few installations which use a multi-thousand dollar database as if it were MySQL (not even using online backup). You can get away with that if you only need a workgroup server license, but if you need 20,000 client access licenses (or multiple per-processor licenses), licensing becomes a problem and you'll certainly consider other options.

    Why not start helping ISP's to block this crap at the source? They are, essentially, what allowed these machines to be zombified in the first place. Aggregators and headends should already have the intelligence to block IP spoofs, which eliminates SYN floods.

    It's not that simple. Network security at ISPs is usually severely understaffed (factor of 10 is not uncommon). Simple filters are easily evaded.

    I've seen what happens if you install SYN flood protection on a target (well, not exactly SYN flood protection, but something which also stopped most SYN floods): some day, the attackers discover another, more obscure tool that works against the target, word spreads about it, and you are mostly back to zero. But this time, it's not a SYN flood (which is annoying as hell, but still a known quantity, so to speak), but something really obscure nobody has gathered experience with.

    To some degree, the situation resembles germs in a hospital. Only few survive the constant disinfection, but these are the most troublesome ones.

    Where is this stated? All I see is that /usr/bin/passwd has a local root vulnerability; to me, that says that if I can exploit a buffer overflow in any arbitrary program, even an unprivileged one, I can get root on the box.

    You've conveniently removed what I wrote: This is true on any *NIX system, there are tons of vulnerabilities which allow attackers who can execute code under a non-root UID to obtain root access.

    It doesn't matter if you fix passwd(1). There are too many other issues, most of which still have to be discovered. You can't rely on local *NIX security, you have to use other means to stop attackers. For example, one widely-used approach is "one machine per service" or "one machine per trust domain".

    BelWue, the regional research network over here, is doing rather fine, for example.

    Linux or no, it seems like pretty much every IT investment made by any government (maybe it's just the UK?) ends up becoming a steaming pile of failure that gets reported ten-times overbudget, 8 years late, and eventually gets either scrapped or audited (those being essentially the same)
