    Yeah, I use OpenBSD. My firewall's named linksys and the SSID is default, both for sheer entertainment value. OpenBSD like anything else has its flaws: namely a insular and hostile user community and theocratic leader with a vision. On the other hand it's people like that who get things done.

    It would be nice to do more with OpenBSD than I can now, but last I checked ports didn't have the latest asterisk, getting the latest Java running is a pita, the latest Apache has an incompatible license or something, ZFS will never be supported, etc, etc, etc. But staying up with the latest software isn't really a design goal for Theo & crew. It's sort of the PVP UNIX - no care bears welcome. Their targeted approach to security over features makes it the best OS out there for targeted uses, but who knows if they'll make it to 5.7 - decreasing relevance and due to narrowing mainstream software support definitely also narrows interest.

    Regardless, congrats on another great release.

      I'm not sure that it has decreasing relevance. For something like a firewall or other networked appliance (where you don't actually have users logging on and interactively using it), OpenBSD is way ahead of the game. Auditing the kernel and securing that is actually a good strategy for such devices, whereas mandatory access controls would be more of a cycle-hog. For reasons I don't entirely understand - or agree with - the world is slowly moving away from desktops and towards appliance-based computing. Look at the rate Droid is accumulating apps, compared to the rate new stuff is being written for Linux.

      I do not know what the ideal security strategy is - I feel that it must involve components that are transparent to any part of the kernel the user or superuser can substantially interact with, because although you can prove a Security Kernel correct mathematically (it is one of the few OS components simple enough), this is useless if there is any means of either accessing the functions protected or re-implementing them, yet nobody likes re-designing implementations and call points are bound to be missed if code changes are required. This means that the security kernel has to act in a manner akin to dynamic probes and inject itself into modules without needing static insertion points. Security then just becomes a form of debug in step mode (continue until next probe, then pause the kernel thread) in which the debug data is analyzed automatically rather than by an engineer.

      OBSD has support for the 20 pin gpio header on a Soekris net4801 board out-of-the-box. With that you can easily make either digital or transistor switches to control things. The shell command is gpioctl which you may want to grab the source and mod it so its not reading command line arguments and can be put in your code without an os system call depending how frequently you are reading/writing the pin states.

      OpenBSD doesn't want to take over the world, see the project goals. This doesn't stop their work becoming used on a large scale, but this happens because of the software's features and technical superiority.

    The fact that the OS code is audited is nice, but can't protect against other insecure software. If you run postfix which isn't audited, and it has a hole and the attacker gets root, then there is nothing to stop them.

    Maybe I'm wrong, but if the mail server isn't crap it should give up root privileges as soon as possible. So, to get root you need to do two things.

    1) Exploit a bug in the mail server
    2) Exploit a bug in the operating system to gain root privileges

    If MAC is part of the operating system, and can therefore contain operating system bugs, how does it mitigate step 2? How does it mitigate it any more than an operating system without MAC?

    An example from a commenter on the blog is that he needed to prevent root from reading users files. OpenBSD is almost the only OS left that can't meet this requirement.

    Are you serious? The root user has ultimate power by definition. That's been the case with *NIX for decades.

    Having read the article mentioned by you (I saw 43 comments,?), I can only agree - and I knew that for long - that OpenBSD has no access control systems on top of the Unix-permissions. If they should be there, and how their lack renders OpenBSD less secure than Linux, is quite another topic. Actually, I was kind of disappointed when reading the article, because it focuses solely on access control to crack OpenBSD. So even the title was badly chosen: the article talks about a perceived 'lack of a security feature' or something to that behalf; not about an 'insecure' OS. And yes, there is a difference, and the article is clear about it: If, and only if, the system is broken into (already), can additional access controls eventually contain damage.
