Linux Most Attacked Server?

Anonymous guy who can't remember his login sent in a story from the Globe And Mail that says "During August, 67 per cent of all successful and verifiable digital attacks against on-line servers targeted Linux, followed by Microsoft Windows at 23.2 per cent. A total of 12,892 Linux on-line servers running e-business and information sites were successfully breached in that month, followed by 4,626 Windows servers."

    Does this count the number of Windows machines that were 'compromised' by BLASTER and its children? If someone gets a binary on my server and controls what my server does ( in this case, replicating the worm ), then I'd call that hacked. Just because a worm did it vs. a human doesn't mean anything. More direct hacks on Linux machines might just mean that there was much more human effort expended.

    Yes, my Linux server is certainly being attacked constantly. I know this because I keep finding entries like these in the apache log files:

    First, In the Windows case, shit might happen because it takes longer for a proper fix to appear (though, on the last DCOM-related vulnerabilities, we should give credit to MS for the quick response to the problem). If a patch does not exist, the admin can not do as much (unless he has a proper firewall).

    I call bullshit. Most Windows problems are patched long before they're exploited. See Code Red, Nimda, Blaster, etc. All of these were fixed long before they were exploited, and yet long after the worms first appeared people were still being hit. While I will agree that there is a possibility of patches taking a while to appear from closed-source software (and that it has happened, usually regarding Internet Explorer), that has been the case only in a very minority of important patches. As well, though you call out Debian's apt-get for making it fairly easy to update systems, Microsoft has Windows Update (and they freely-available provide software to run your own Windows Update site, so that you can verify patches before pushing them out to your site). Therefore, your argument is a red herring.


    But it all depends on the administrators.

    Bingo! 99.999% of all of the problems with both Linux and Windows being insecure have stemmed not from late patches, but from administrators not keeping on top of security for their machines.


    Oh, and yes, there are more viruses for Windows, but that includes the 'dumb end-user' type such as SoBig, which are purely unrelated to server attacks. And those, I'm more than sure, will _not_ appear an Linux systems since I do not know of an email client that makes it so easy for a user to execute incoming garbage straight away.

    It's false to say that Linux will not ever be affected by such viruses, because it's quite possible. Even with proper separation of user rights and administrator rights, a user can still royally screw himself and his data. More, all it takes is one unpatched local root exploit ("I'm not too worried about local exploits, because they're local" is an attitude that will get you in trouble if you have users ...), a malicious binary that exploits it, and a dumb user. As well, with more users wanting to use Linux, the need will come for user-friendly desktop apps (what do users want to do? easily open e-mail attachments. Better code that properly, our you're going to be as bad as Outlook Express ...). Users will also want to be able to easily install software (see Lindows, and how at least initially it suggested you not only run as root, but without a password!). There's work to do on Linux before it will be acceptable to Joe Sixpack or Bettie Secretary, and unless developers keep their wits about them they can (and will!) fall into the same problems seen in Windows.

    A friend went to clean up a server that finally crashed under the load of Blaster. When he went to that site, he found that the server also still was infected Nimda.

    Needless to say, the regular server administrator for that site is in an uncomfortable spot now.

    Then I guess they just went down in quality.

    A trivial demonstration of the problem is to take the number of reported virus infections with Sobig and friends. Compare with the mi2g figures about proven break ins. Note weird difference in size of windows numbers.

    As to web sites they *appear* to count each web site affected. So a single linux breakin on a big hosting site scores 10,000 while nobody hosts 10,000 sites on a windows box.

    One of the problems with a lot of these metrics is the lack of a fair, formal and neutral third party methodology for analysis of such data that can handle the way proprietary vendors forget to reveal most bugs but just roll them quietly into updates, the difference between vendors in quantity of material and remove overlaps.

    Unfortnately that isn't likely to change. There is a marketing game being played by many vendors and security is simply another buzzword and another set of statistics to "optimise". Customers are expendable.

    I guess the final thing we all should notice. The number isnt zero. That only emphasizes the need to get more stuff like SELinux out and equivalent other OS products. Preferably before the bad guys mix something like Sobig or slammer with something that does actual damage, potentially hardware damage.
