Re:Just wondering..TedCheshireAcad asked
If Win2k gets a higher rating than Linux, then why do we have stuff like this happening?
No, it is not odd. It is expected, in fact. Microsoft's rating was for common criteria "CAPP/EAL4". The CAPP part means that the OS provides "a level of protection which is appropriate for an assumed non-hostile and well-managed user community requiring protection against threats of inadvertent or casual attempts to breach the system security". I don't consider the internet to be a non-hostile and well-managed user community, so I'm not the least bit surprised that hostile remote attacks are possible. The evaluations didn't say that it was safe to hang the microsoft box - or the linux one - on the internet.
Isn't it odd that a "comprehensive security rating" can overlook something as serious as a complete remote compromise?
These lower level security evaluations don't mean much in terms of real security out on the big scarey internet; i.e. the situation most of us find our machines in all the time. (This has been discussed on slashdot before.) Basically, all that is necessary to get one is that you document *everything* and then throw a pile of money into having a government-approved independent organization evaluate your product and make sure that it does what the documentation says it does. If your product behaves as your documentation says it does, you get the certification. It is worth noting that OpenBSD, who have only had one remote hole in the default installation in seven years, have avoided these types of certifications for a long time. Look at Theo's comments on the C2 rating in the Orange Book (the predicessor of the common criteria.) This is the formal description of EAL4 in the official list of evaluation levelsEAL4 - methodically designed, tested and reviewed
Notice that the goal is to "retrofit" a product line with security, and only to the degree that doing so is "economically feasible". Compare that with Bruce Schneier's comment that "Security isn't easy, nor is it something that you can bolt onto a product after the fact." No one should be surprised that feature-rich, general purpose operating systems designed for quick and easy use (i.e. everything turned on by default) are vulnerable.
EAL4 permits a developer to maximize assurance gained from positive security engineering based on good commercial development practices. Although rigorous, these practices do not require substantial specialist knowledge, skills, and other resources. EAL4 is the highest level at which it is likely to be economically feasible to retrofit to an existing product line. It is applicable in those circumstances where developers or users require a moderate to high level of independently assured security in conventional commodity TOEs, and are prepared to incur additional security-specific engineering costs.
An EAL4 evaluation provides an analysis supported by the low-level design of the modules of the TOE, and a subset of the implementation. Testing is supported by an independent search for vulnerabilities. Development controls are supported by a life-cycle model, identification of tools, and automated configuration management. -
Re:What about BSD?
I agree. I wish the government would take a serious look at, say, OpenBSD for example, and maybe even donate a couple of bucks to them. I've had my rounds with OpenBSD, and it's straight out damn secure.
I don't see why most /. people hate *BSD. It's a great and rock solid system, I'm using FreeBSD myself, in addition to Redhat Linux and Windows XP. -
Funding? Needed at All?OK, so you are going to hire highly experienced and expensive talent to do security audits for open source projects that don't have a revenue model? Where's your revenue model?
And of course, the benefit of open source is that all sorts of motivated, talented people from all over the world pitch in to do a similar analysis for free, and without a formal "red team." This breaks down quite a bit with the volume of Free Software being produced nowadays, however. But the important pieces of infrastructure (Apache, e.g.) DO get the scrutiny their importance demands. Not to mention pounding by black hats.
Someone mentioned OpenBSD. But even they don't audit everything. They confine their attention to the core of the OS. That's quite a lot of software, but the ports tree is quite a bit more. The ports get somewhat more attention than they would simply because you've got a large set of security conscious users. -

Re:Unnecessary - encrypt your file systems instead
Encrypted file systems are a pain to configure and they suck up CPU time. If this can be done in hardware, that's a good thing.
If this can be done in the hardware correctly, that's a good thing. One can't go about blindly cheering such unproven technology. I'll sound like an ass and say I'll wait for more reviews before trusting the ABIT encryption scheme. Trusting a faulty encryption (or security) model is not a good thing.
For now, one can depend on older devices such as these cryptography accelerators. Soon, Linux will also include support for such devices. -
SMP in the *BSDsQuote from the article:
GNU/Linux has an amazing amount of native software packages and supports a modest number of CPU architectures. It can easily do symmetrical multiprocessing (SMP) with up to 16 CPUs (the 2.6 kernel can do up to 32) unlike Free/Open/NetBSD which is still struggling with proper SMP implementation
Oh, really? I know OpenBSD isn't quite there yet. but what's not proper about the SMP implementations in FreeBSD (5.x) and NetBSD? Inquiring minds want to know, can anyone here shed some light?

Re:Honest Portability QuestionI don't see anything in the GPL that would prevent including ReiserFS with a BSD kernel.
OpenBSD has issues with including GPL'ed code. Theo de Raadt gave a very short initial answer.
OpenBSD are very keen on keeping their code untainted.
-
Re:The next widespread compressionThe replacement for pkzip should be gzip.
OpenBSD is working on removing GNU software from their OS. By porting BSD userland to Linux, perhaps we can talk about BSD/Linux

Speaking of security risks
There are multiple vulnerabilities in the Linux 2.4 kernel.
Get your patch here, here, or here.
BTW, there are no security patches required for OpenBSD 3.3 yet. -

Re:Windows ...
Try an OS [openbsd.org] that has been worked from the ground up with security in mind.

Re:Windows ...
OpenBSD did only have a single exploit in the last seven years. (In default install profile).
But i'm not sure it was in the last year, if it's earlier then OpenBSD is your answer! :) -

Re:BSD - Remote Holes
Isn't that true of *any* solid server OS?
There's always those virus/worm/exploit things. It's my observation that Windows has quite a few.
It looks like the latest FreeBSD (4.8) has a one and the previous release (4.7) had a few.
The last OpenBSD (3.2) had 14. The new version of OpenBSD (3.3) has been out for over 2 months and doesn't have any yet. That's pretty impressive.
Interesting that several of the flaws in FreeBSD and OpenBSD are the same bug.

OpenBSD?Written with Freebsd in mind many of the techniques in this edition adapt well to other sources such as Linux, Os/X, Unix, NetBsd, and Solaris.
No love for OpenBSD? It's arguably the best OS for security and firewalls.

Re:Okay ...
If I really want to do some web browsing secure from local sniffers I could fire up netscape from my basement but with the display on my notebook. (X has some bebefits.) It would be slow, but it would work.
True, but I'd think it snappier to use the included SOCKS4 proxy that comes with newer OpenSSH software. (It's the -D option.)

Been there, done that
The process is really easy. Get a TV tuner card that is supported under your favourite unix-like flavour, for instance a Hauppage BT 878. Open a remote X session and start the TV application. Voila. (maybe some reencoding should be done to get it all the way to france- 100 mbit works if you don't mind

In other news, I wonder what a beowulf cluster of these would take for bandwidth.. -
openssh and kerberos
seems like the story submitter jumped the gun a bit. from http://www.openbsd.org/plus.html
Add kerberos-over-ssh2 support to ssh(1).
though, reading some openbsd mailing lists, i get the following:
the openssh maintainers would like to have full kerberos support in openssh. however, the mit kerberos code is full of bugs and poorly maintained. the openbsd and openssh developers are sick of dealing with it, and are trying to minimize use of kerberos in the system.
kerberos 4 has been pulled out of openssh and openbsd for the above reasons. -
Re:Why bother?
There's lot more in debian than stability and apt-get.
...such as..?
Social-contract,
Nice if you're religiously inclined; which I don't believe that most slashdotters are...
extensive multiplatform support and compatibility,
Which NetBSD does better, hence the Debian Port to it.
serious full-disclosure security policy ...
Which does better [hence the 'no remote holes in the default install" bit]
However, using debian DOES allow you to feel 31337 on slashdot (whoops, I spoke too soon) and feel superior by bullying [RTFM n00b] helpless newbies on IRC.
While I use debian (out of habit), I question that it's time has not come and gone... -

Re:This doesn't really surprise me...
I think I'd prefer Debian over an OpenBSD system, here's why:
OpenBSD requires that you rebuild stuff when a security update is released. This requires gcc to be installed, and enough disk space to actually build on, as well as enough memory, etc.
Here is some info about how you patch OpenBSD: http://www.openbsd.org/faq/faq10.html#Patches
Debian is a binary distribution. All that needs to happen is you download updated packages built by someone else, and drop them in place. No need for a compiler, and all of the build dependencies to rebuild whatever when a security problem is found. -
This doesn't really surprise me...
With the price of PC components dropping so rapidly, and how much Linux's iptables absolutely blows as a firewall compared to, say, OpenBSD's pf, this was a sure thing destined to fail.
Just think about this for a moment -- "single floppy distro." You take one of the most unreliable forms of disk media, the floppy disc, and expect it to run something continuously and reliably, such as a firewall/router. You can easily build a PC for $50, put BSD on it (which by the way is easier to install than Debian and easier to configure than iptables), and spend your time doing something more useful, like partying with girls instead of configing your firewall. -
Re:The GPL: Intellectual Theft
"Furthermore, after reviewing this GPL our lawyers advised us that any products compiled with GPL'ed tools - such as gcc - would also have to its source code released. This was simply unacceptable."
This is simply untrue. Many non-free systems are compiled using GCC. Many propreitary systems are built using the Gnu Compiler Collection, and I have never heard of the Free Software Foundation claiming that they must release their code. I think this is either a misinterpretation by your lawyers or general just fear, uncertainty, and doubt on behalf of your company.
"I think the biggest thing keeping Linux from being truly competitive with Microsoft is this GPL. Its draconian requirements virtually guarentee that no business will ever be able to use it."
The GPL is hardly more draconian than the Microsoft EULA. Furthermore, the GPL is clearly not about companies. The GPL is about giving freedom to the user.
"Everyone was very pleased with Linux, and we were considering using it for a great deal of future internal projects."
Your comment significes the overwhelming sensibility of sharing code. All the public resources that have gone into creating the myriad of propreitary products is generallyh wasteful. Their is no point in trying to re-invent the wheel. Their is no point in not sharing generally useful technical information.
I personally admire what your company did in contracting to modify Free software for specialized purposes. This is exactly how Free Software would benefit to our economy, especially for developers such as yourself. The only reason that things like Microsoft EULA's exist is so that someone can take away the freedom of their users and exhibit a system of power over them as people. The arguement that companies must protect their intellectual property is flawed because the money that they make generally doesn't go into paying for the costs of distrobution. It goes into things like making Bill Gates a very rich man. That's a system not at all concerned with compensating the developers, once you make an analysis and really think about it. -
OpenBSD firewall
This makes me want to step up my plans to put an OpenBSD firewall in place...
The BSDWall project already done most of the work for you. Assuming that you have an old pc with a couple of NICs in it and a broadband connection, you should be able to build your firewall in an hour or less.
"bsdwall" is a Perl script that turns an OpenBSD box into a working firewall. The site includes
- Instructions for finding and configuring compatible network cards
- OpenBSD install directions
- How to install the bsdwall package after your first boot of an OpenBSD machine
- How to configure and control your firewall
One minor quibble: bsdwall works properly with the latest OpenBSD (3.3), but the install instructions on on the BSDWall site are still for 3.2. Just substitute the 3.3 install floppy for the one mentioned on the website (or buy a CD) and remember that the prompts on the the screen won't exactly match the website's directions keystoke-for-keystroke.

Re:Corporations pay taxes too...But your rights end where mine begin.
Actually it is not that simple but that is beyond the scope of this debate.
I also paid taxes on that code and also get a say in how it is used.
Which is exactly why the code should be released under a license which puts as few restrictions on its use as possible: to allow as many people as possible to use it. Take a look at the latest version of the BSD license used by OpenBSD. Simplicity itself. It says who the copyright holder is, that you can do anything with the code except change the copyright and that there is no warranty. It doesn't get much more free and straightforward than that.

About time, I sayThis is only second book in history on OpenBSD.
That doesn't mean that OpenBSD is bad or has a small group of supporters.. It's only one of the most secure ("out of the box" is one of the items of high importance to me) firewall operating systems in the world. It's completely Open Source and available for free download.
The original book on OpenBSD from the year 2000 is sorely outdated since the OpenBSD project tries to release a new version every six months. This book covered lots of security/firewalling concepts and how to implement them in OpenBSD 2.5 (as well as Linux) while we are now at OpenBSD 3.3. The above-mentioned books should be able to help fill in the background details as to the "whys" more than the "hows."
The "hows" are provided on the OpenBSD website for free:
FAQ (installation)
Packet Filter User's Guide (does most of the amazing firewalling that OpenBSD is famous for)
Manual PagesOpenBSD is freely available for download, but if you like the project, I strongly encourage you... Buy something from them (they have a few shirts and posters): Or donate money or hardware.
Also, I wonder if this book is in any way related to the Deadly.org plea from the community for topics that an OpenBSD book should cover.
