I uninstalled OpenBSD the other day after using it since OpenBSD 2.7 came out eleven years ago. I had grown used to it and contributed too, following the OpenBSD mailing lists and even submitting code a couple of times. But when I began thinking seriously about security, things began to change.
After the debacle that arose about US government-funded backdoors in OpenBSD's IPSEC back in December ’10, I've had a suspicion lurking in the back of my mind that I just can't shake. If having backdoors was such a serious potential security liability, how could anyone be satisfied after just a week of auditing on such an important part of the OpenBSD codebase?
When looking into the audit I found some disturbing news. First, a proper audit is done transparently, with the methodology and results should published for end-users to read. Since the OpenBSD Foundation has no means to track who's actually using OpenBSD, that means that the results should be available publicly. But they're not.
Go ahead, try googling something like “openbsd ipsec code audit results” and see what comes back. Plenty of discussion, but nothing published by the people who performed the audit. Without that, we have no idea who did the audit, how the it was performed, or whether they found a backdoor.
So the question remains: are we sure that there is not a backdoor in OpenBSD's IPSEC?
Without knowing, there are some wide-ranging repercussions. Bits of IPSEC code may have made their way into other, more-widely used, products like Mac OS X, and for day-to-day OpenBSD users, who use OpenBSD for more than just routing and have their lives and livelihood on their OpenBSD boxes, the problem is very immediate and important.
I approached Theo de Raadt, OpenBSD's founder and leader, about this and asked if there would ever be a formal, published report on the audit. My asking led to my third reason for uninstalling OpenBSD: in typical Theo fashion, his reply was not only terse but also betrayed a lackadaisical attitude to his own operating system's security:
FROM: THEO DE RAADT <DERAADT@OPENBSD.ORG>
SUBJECT: RE: QUESTION ABOUT OPENBSD SECURITY
DATE: SEP 29, 2011 21:09:50 CST
OpenBSD is the most secure operating system in the world. We don't have to publish anything, and if you don't like it then don't use it. The end.
P.S. Don't contact me again.
With the leader of OpenBSD saying that OpenBSD's reputation will be enough to keep the hackers away, I just can't agree that OpenBSD is “the most secure operating system in the world.” Theo's cavalier attitude toward due process and security isn't just unprofessional; it's profound idiocy. To see my point, just check out the title of OpenBSD 5.0's theme song.
And with OpenBSD 5.0 on the horizon and nary a peep on this serious security issue in sight, it's time to move on. Theo can release as many updates and funny logos and silly songs as he wants, but the fact is that the only way to gain serious security credibility for OpenBSD is to pursue due process. Until then, OpenBSD is a minefield of holes and cracks. OpenBSD is about as secure as swiss cheese.
So today I urge you to find an operating system whose development team takes security seriously and uninstall OpenBSD posthaste. There are many out there, so take your pick: Mac OS X, FreeBSD, NetBSD, or even Linux.
Just know that running OpenBSD is taking a huge, unnecessary risk. Don't play games with your security. Uninstall OpenBSD today.
You must be trollingReplyDelete
Please don't contact me again.ReplyDelete
trollaxor would never troll. I suggest you check your facts.ReplyDelete
How many issues with OpenBSD do you not know about? Knowing about issues and having them fixed makes me feel better about those 3 OS's.
So just 'I think' 'It may' and you throw it away.ReplyDelete
It's really short story.
awe did theo hurt your feelings ? .. maybe he's busy doing real work rather then explaining things to you ?ReplyDelete
LOL !, keep your zero days for OpenBSD and go away right now!ReplyDelete
You are right. Theo's "if you don't like it don't use it" reply is, in fact, not a reply.ReplyDelete
The issue of secure configuration was a concern I had back when I was using OBSD: however, since it shipped with everything "off" the blame-the-victim-you-fucked-it-up position absolved OBSD of any blame. But what use if OpenBSD if everything is off? The first thing anyone does with their box is turn on services.
The nice folks at el8 complained gently that OpenBSD had some possible issues with wholesale importation of device drivers.
Security through reputation is nice, but their claim of N holes in Y years doesn't mean much because you can't compare it to anything (or you could but they don't).
An excellent "troll". Troll HARDER.
Unistall OpenBSD to install Mac OSX or Linux. As a security related step.... Seriously ?ReplyDelete
Yes, Linux. A hardened Linux is SECURE, proved by tests and comparison, not by "because I say so".Delete
Irony. Security through obscurity is the OBSD solution. OBSD should be called CBSD.ReplyDelete
If you think that OpenBSD is backdoor'ed, why would you ask the person that would potentially be involved with installing the backdoor?ReplyDelete
If your blog post said "I audited the OpenBSD IPSec code and I found a backdoor", then your blog post would make sense and your opinion would be worth reading.
What's the point in using OpenBSD and complaining about it if you don't even read the source code? If you can't read the source code, then you really can't and shouldn't trust ANY OS, given your logic.
Read the source code and if you find a backdoor, you win a prize.
Let's face it. Theo is a prick who is convinced he is always right, everyone else is a fool, and if you don't like it, get out.ReplyDelete
That's why you shouldn't actually depend on OpenBSD for anything. The question isn't whether it's secure - it mostly is, and I doubt it's any worse than any other OS - but the "owner" just isn't worthy of your trust.
you stupid morronReplyDelete
There are some good points here; the name is OPEN BSD, so why was the audit not open? Even Theo would have to admit that the apparent secrecy is contrary to the spirit of what he espouses for security.ReplyDelete
One almost HAS TO ask, why the audit was done that way.
I still see OpenBSD as a secure OS given the track record.
I'd get the same reaction from users in one of the XCHAT rooms devoted to OBSD. They (the users) seem to avoid the question, and if you continue, they shut you out. IMO, OBSD users (many, not all), have a serious attitude problem. I found two Linux releases that can meet, even surpass OBSD -LIBERTE Linux, and EnGarde Linux (security so tight, makes OBSD look like it was written by a clown (maybe Theo IS a clown - lol)).ReplyDelete
Yeah, remember 2008 when it was discovered Debian was generating useless SSH/SSL keys because of a developer who commented out some random number generation that were throwing errors? For 2 years you could decrypt any SSH login http://research.swtch.com/opensslReplyDelete
This is the difference between OpenBSD and almost every other distro: quality software auditing for security and stability. You can actually audit the OpenBSD base code (and they do). Linux Kernel development is now 15 million lines of code nobody can audit that. You're freaking out about something you yourself could look at and decide if it's secure or not, because it's transparently open to the world to see, and kept small to avoid the ballooning propagation of errors which is 15 million + kernel lines of code.
EnGarde Linux and LOl liberte (enjoy using their cable communications which is a complete joke. not anonymous whatsoever) may be using 'hardened Gentoo' and have all sorts of fancy knobs you can fiddle with claiming to be MAC and stack overflow prevention but is completely useless because you're still running it on 15 million + lines of insecure kernel development. The entire core is broken, who cares about the icing being impressive.
Linus Torvalds does not follow any sort of sane development cycle, he just pushes out features as fast as possible. There is no security focus, because Linux was never about security, and much of the old school guy's who sorted this stuff out and gave a flying f about quality control and bug squashing like Alan Cox all quit.
Look up Histar, a tiny O/S purposely designed by PHD researchers to be ultra secure. You can audit all the code in a few days. But it has no knobs to fiddle with or fancy MAC fluff pretending to be security, so I guess you wouldn't like it.

There were patched a few yeurs later by the audit process of OpenBSD, and were only weakening openbsd a noticable small amount.
Credits to the OpenBSD audit process: that backdoor was difficult to use.
A secret audit is absolutely valueless.ReplyDelete
Imagine if drug companies were allowed just to claim that there drugs were safe without publishing any evidence that they had been tested or explaining the methodology or stating who had carried out the tests and what their experience was. Would you take the drugs?
Theo is completely deranged and anyone who trusts someone who clearly has mental health issues to "do the right thing" is a fool.
What was the second reason? You only mention first and third.ReplyDelete
