Re:Which are more successful?
[If something does't seem completely logical or contradictory somewhere, like MS being on the same level with RedHat in one place and with Sun in another, that's probably because I'm merging things I found in two different articles that were written almost half a year apart]
You could look at it this way: for the past couple of years, the number of vulnerabilities discovered in WinNT and 2000 combined has been at approximately the same level as that for RedHat linux alone, and at about 50% of all linux distros combined. The absolute leader in the vulnerability top 100 is Mandrake, with M$ sharing the 4th position with Sun.
It's not because headlines don't cry out that the world is about to end everytime a hole is found in linux/solaris/unix, that none are found.
Only this year, and that's because MS expressly started searching for them, the number of vulnerabilities found in Win2000 is rising - above RedHat, but (at the time of the article I can't find anymore - see below) it still looked like it wouldn't surpass all of linux combined.
So where do you think attacks would me more successful?
Source: "here or here, "Windows more secure than Linux?"
I thought I saw another article last Friday with more recent figures (including the first months of 2002) and saying that this ratio, except for the peak in 2002, has been constant for a couple of years, but I can't find the blasted thing anymore.
Also interesting is this page where a number of people explain their ideas about win/lin security. I suppose most /. nerds are going to call it biased because linux doesn't exactly come out good.
Some people reacted to the first article that comparing a single OS to all flavors of linux combined isn't honest, but (1) NT and 2000 aren't a single OS any more than linux is and they represent a larger installed system base, (2) even in the case of a few individual linux distro's MS still wins, and (3) neither is combining all the good sides of different linux flavors, or comparing the holes in an OS plus those in all its apps to just an OS alone, and all of these are daily habits in linux advocacy if it fits the linux side. -
My Security HOWTOLinuxsecurity.com has a mailing list you can subscribe to in order to get frequent updates on things. Another poster stated a few obvious things (which are always good advices) including: CERT, SANS, BUGTRAQ, linux networking, etc.
A few bible-books in my library include:- "TCP/IP Illustrated Vol.1" by Richard Stevens published by Addison-Wesley
- "Intrustion Detection: An Analysts Handbook" by Stephen Northcutt published by New Riders
- "Unix System Administration" aka The Red Book by Nemeth, et. al. I believe the Purple Book is the 3rd edition (I am open to corrections)
- 2600 The Hacker Quartlery. A quarerly zine that most slashdotters have read, subscribe to, (or in this new-age, have either never heard of it and/or will flame or mod this into oblivion)
- the "Hacking Exposed" series by Stuart McClure, et. al.
Install more than 1 linux box (and RedHat, SuSE, Debian [and anything else that's popular] DOES NOT count. Use Slackware so you can have some semblance of control and learn how things work).
Don't install X; tough it out with the shell. <elitism>We all did.</elitism>
Grab your hands on a Solaris machine, x86 will suffice but try to get a Sparc. That way you'll understand how to do things across multiple platforms.
Setup a network and a routing firewall inside (ie: no masquerading). Then learn that and setup a masquerading firewall for all that to get to the Internet through your gateway.
Oh, Get nmap! And learn how to use it SAFELY and WISELY on your own stuff.
Read Read Read Read Read! Drop your girlfriend. Sex is good but if you wanna learn it hard, she'll have to go. If she's a geeky girl, have her help you out. She can learn too.
After that, let us know how you did. Take a security test somewhere. Online or Real World, it don't matter. It's fun shit! We love it. But it's hard work to learn it. Once you do, you'll never be the same again and you'll be very very l33t. -

Re:Complacence will get us nowhereThis document outlines the kernel security improvements that have been made in the 2.4 kernel. A number of significant improvements including cryptography and access control...One of the most obvious and significant improvements in the 2.4 kernel is the packet filtering capabilities.
A program such as xntpd might go through the following process to relinquish the rights that are not necessary for normal operation:* Start with full root privileges as it normally does
* Bind to the privileged ntp port
* Drop all capabilities other than CAP_SYS_TIME
* Drop root privileges (preventing it from even writing to root-owned files)
* Continue normal operation as a regular administrative accountCurrently, programs need to be modified to take advantage of capabilities. With filesystem capabilities, this sometimes won't be necessary. It might go something like this:
[root@magneto
/root]# chattr +CAP_BIND xntpdThis would enable the xntpd process to bind to a socket without requiring root privileges prior to being run. Quite powerful. At the same time, it's also contains a certain potential danger due to making an unprivileged binary slightly privileged.

Re:A testament to open source...
It's not accurate to say the vulnerability was discovered "just a few hours" ago. I got an e-mail from a Mozilla security list on Feb. 19 with the subject "serious zlib vulnerability". The first line of the message was "It's very important that this doesn't leak out until after March 11th, when vendors should have fixes available." If you look at the references from Red Hat's page about the vulnerability, you'll see documents with dates like 2/5 and 2/7.
Asa informs me that the zlib bug and its announcement on Slashdot today didn't influence the decision to release Mozilla 0.9.9 today. He was already planning to release today, and since the zlib vulnerability was made public this morning, it made sense for the release notes to mention that it is fixed in this build. -
Where can I get the PNG of death?
According to one of the provided links, the problem was originally discovered when an invalid PNG file caused libPNG to crash. I'd like to get this PNG file and throw it at a development server here at work before a script kiddie posing as a customer does. Any idea where I can get the PNG of death?

Re:Athlon/Duron ProblemsYes, that's right, yet another Linux bug was discovered the other day. So, right about now, if you're a clear headed Capitalist, you're probably thinking "Who cares? They find a new bug in Linux daily." Well, you're right. But there's more to the story. Apparently Alan Cocks (a Red Menace Commie who censors documents under the cloak of the DMCA) is trying to pass the blame on another co-conspirator of Communism.
Apparently, if you'd believe the Linux community, you'd be hard-pressed upon where to place the blame. You see, the Linuxist Manifesto's number one rule is to lie to protect the best interests of Linux. No self-respectable Linux zealot would insult or place blame upon AMD, because AMD's philosophy centers around tackling American Corporations with their Asian sweatshops, selling their chips at bargain-basement prices like the Red Menace Commies do with their Wal-Mart shit.
So, right about now, you're probably thinking that the zealots are clearly in a dilemma. Who are they going to blame? If you have a prediction before I tell you, the poll is on the right. Or maybe the left. Either way, take your pick.
You'd think that the parasitic community would place blame upon Microsoft, right? Alas, Microsoft has had the bug patched since September 2000. Not only that, Windows XP , the latest in the suite of high-powered, stable operating systems from Microsoft Corp., has this patch built in. That's right, built in. Keep in mind that Windows XP was released in October 2001, over three months ago. Meanwhile, no one knows what the hell Alan Cocks has been doing since then, since he hides under the cloak of secrecy. nVidia has been informing users via tech support, even to the Linux community, how to fix the problem for months now. Clearly the blame is upon Alan Cocks's shoulder, but to place the blame where it is rightfully justified is inexcusable in the Linux community. The drones are in disarray.
The actual bug occurs when Linux users contract the Tux Racer virus via KEmail. When first run, Tux Racer enables a feature in your third-world sweatshop AMD processor called "extended paging." Now, I know you're probably thinking that this sounds like some sort of Nokia feature. Well, you're wrong. It's yet another feature that AMD illegally hacked from Intel. It allows your browser to seamlessly view pages up to 4Mb in size. Before its introduction in the early days of the Intel Pentium processor, web pages were broken up into 4K segments, because any pages larger would freeze the computer. That's why Microsoft didn't invent Javascript until after the Pentium, every time they went to use it, their pages exceeded 4K, and henceforth froze the computer. Intel came to the rescue with the Pentium line of chips, and, as usual, AMD got out their super high tech Asian hacking tools and "reverse-engineered" (code-name for 'illegally hacked') Intel's technology. Thus, users of the inferior AMD Cyrix Kx86-2 Now! processor could also view large web pages without crashing. So why did no one notice that pages larger than 4K would crash AMD processors? Well, Microsoft has had a fix for 16 months, like we mentioned earlier. But why did no one from the Linux community notice? Well, apparently, there does not exist a page devoted to Linux that is more than 4K in size. Since most of the Linux installations out there denounce color as 'feature bloat,' all Linux pages follow an unwritten oath to suck. Believe me, they all do.
So, for the good of Linux, you may now disperse. Head off to various tech sites and continue blaming Microsoft for not telling you sooner. Your community will thank you.

It's the PRINCIPLE, Stupid
IANAlan Cox, but what 99% of the people in this discussion fail to realize is that this probably has nothing to do with the future of Redhat/Linux, but with the principles involved.
Fact: Alan Cox has serious issues with the DMCA, both practical and philosophical.
Fact: AOL/Time-Warner, being an industry leader in the area of movies and such, is a proponent of the DMCA and other similar laws.
Alan, being a man of principle, probably feels that the merger would be a bad thing becuase of this, and his working in the resulting company would comprimise things that he believes in. Unlike many people in this world (and, it seems, on slashdot), he feels the finding a new job is the proper course of action in this case.
As an aside, the non-Alan consequences of this are interesting - AOL/TW owns RH, in order for RH to play DVDs (which is an important feature of a modern desktop OS) it needs to violate the DMCA, AOL/TW supports the DMCA. So with AOL/TW owns a product that endorses breaking the DMCA, or they give RH (and by that, perhaps all of Linux/x86) a "legal" (if not open) method to play DVDs. -
Re:Complete security
The SecurID tokens work pretty well; they represent a nice balance of security and ease of use for the inexperienced user. The server software is a hulking piece of difficult-to-manage bloatware (it was when I last used it two years ago, in any case), but it's generally being installed and used by experienced folks.
The cards themselves have some tamperproofing that protects them from casual disassembly, but it doesn't look like something that's designed to withstand a determined attack. I think it'd be much harder, though, to access the internals of the card in a way that wouldn't leave obvious visible evidence of tampering--I'm guessing this was the design goal, not total tamperproofing.
The algorithm used by the cards isn't something that RSA publishes, but it's been out in the open for a while now.
The cards are each preloaded with a secret key, which is also loaded onto the SecurID server that does the authentication. Without the secret key, the algorithm doesn't do you that much good so long as it isn't easily possible to derive the secret key from a sequence of the displayed number. The jury is still out as to whether this is possible. But assuming there aren't obvious holes in the algorithm, one has to obtain the keying material from the server (where it's presumably closely guarded) or from the physical token itself. Doing the latter would require theft of the token or tampering in a way that would be obvious to the user. -

Re:This is bad why?
AFAIK, banks have a own seperated network.
The DARPA-NET was created to provide a mean to communicate after a nuclear-strike or any other physical attack.
It should be redundant (and by this mean fault tolerant).
Therefor all partners were more or less equal.
It didn't matter which way the packets go and it shouldn't matter.
Security was never a main issue as you can see from the amount of security flaws, which exist(ed) in TCP/IP.
Granted, IPv6 seems to tackle these problems, but it is still not in use. And sometimes it's easier to build something new than to change the existing (I would suggest doing the same with tax law).

The Cheese Worm did this for Lion-infected hosts
The Cheese Worm seems to constitute exactly what you want. Cheese actually sought out Linux hosts infected by the Lion worm and removes any backdoor root shells from
/etc/inetd.conf . Some say the Cheese Worm constitutes the first hack-of-a-hack known.Another first for Linux and Open Source software!

Re:No .Net for Linux? Cry me a river.
what does the future bring with the
.Net strategy? Lost privacy? Stupid security bugs everywhere? Pay-to-play software?
Typical anti-MSFT FUD.
I haven't lost any privacy using .NET (no, you do NOT have to use passport).
Security bugs? Yes, IIS has had and still has a HUGE problem with these rediculous buffer overflows, but it doesn't look like MSFT is the only one with recent major security problems.
Pay-to-play is a business decision, and is not an inherint attribute of .NET.
what are the chances that .Net vulnerabilities will have reprocussions across all Internet services and platforms?
What are the chances that the same goes for J2EE with Sun ONE? It's the nature of the interconnected beast. -
BSD rants and ravesBSD isn't going anywhere any time soon contrary to what a troll thinks. In fact BSD should have an easier time in the upcoming months via way of (evil drum roll) Microsoft.
This week, Microsoft announced that it will work with Corel to port the
[source] My only pseudo concern with FreeBSD is, I wish they would scrutinize what is released via the ports more, this way they wouldn't have to release patches as much as they do, but again in comparison to Linux, as with OpenBSD many services aren't run off the back, and as with OpenBSD, unless you're going to pkg_add .NET Common Language Infrastructure and the C# programming language to open-source OS FreeBSD, a Linux competitor ... Contrary to reports, this porting effort doesn't constitute an implementation of .NET on FreeBSD, but involves only some of the low-level technologies that are part of .NET. Microsoft's decision to use FreeBSD rather than the far more widely used Linux is reportedly because of the company's disdain for Linux's GNU Public License (GPL), which Microsoft has described as "Pac-Man like" and "a cancer." The FreeBSD license is reportedly far more amenable to Microsoft because the license doesn't require the author of commercial works to provide the source code to others, as does the GPL. /cdrom/packagaes/ALL || make install /usr/ports , you're not going to have as many issues as you would with other OS'. For the Linux zealots yes you have your `secure Linux` variants, and you also have advisories for those too [check Linux Security], Trustix, EnGarde, etc. they're all there. NetBSD is a sleeper for all, it's still a nicely written BSD, and I think it'll be around for a while. Open is well Open, and isn't going anywhere soon, love or hate Theo & Team OpenBSD but I still feel comfort knowing soom rootard isn't going to to anything to my servers at any give time. -

Linux was developed with publicly reviewable source code, and as such, has been subjected to a tremendous amount of security testing. In our opinion, as a provider of internet services, our server is more secure and stable than Microsoft Windows NT.
Sure it was, four or five months ago. Things change.
An individual with enough computing power and 'hacking' expertise could crack a password and gain access to the system. Such an individual, in order to crack the password, would also need direct access to the network that the RAQ administrator uses to access the RAQ. Once again, this feature is inherent to nearly all Unix systems.
But, uh, if the machine is relatively secure, how exactly is the attacker going to get to /etc/shadow?
The RAQ II server uses Sendmail 8.8.8.
Errrrrgh...
I think what you've got is an ISP that will start you off with a server that was secure a few months ago (or currently, raise your hand if you think they check). They leave you responsible for hardening it and most likely give no support whatsoever... Well, at least not free support. A lot of co-location companies are doing that.
I hate to plug, but if you're looking for another dedicated provider, I would try Rackspace. They start you off with a pretty secure server with all the latest packages and will apply a patch for you, help you, or do any work of that type for free.
But, here are a few sites that will help you get familiar with Linux security:

Dave rules.
Nice to see Dave Wresky on Slashdot. He is one of the good guys, and you should use his company Guardian Digital if you need consulting. He is smart, nice and a technical whiz. I've heard Paul "Rusty" Russel give him a solid thumbs up... Security doesn't get better than having the guy who wrote all the firewall code give you an endorsement! see linuxsecurity.com

Download Site / Comments
LinuxSecurity.com is offering bandwith to download the images at http://honeynet.linuxsecurity.com/
A project such as this does such a good job of exposing users to the methodologies of the black hat community. This is a great project for anyone who has even been hacked or might be hacked in the future. Its an excellent idea to play with a compromised system to see what one looks like, what gets "messed with" and what needs to be fixed.

Re:Server concern
Isn't this more of a server concern? I mean, even if my system was "compromised" (the official-sounding wording in the FAQ) why would I truly care?
Section5.2 of the FAQ covers this. Kind of. Do you want to explain to the police that you didn't know about the warez and child porn on your hard drive?
All-in-all, would I even need security if there wasn't the internet? If the machine was just sitting in my room and the only thing that could "attack it" is a 12-year old brother with a misladen hockey stick? Probably not.
Less so, maybe, does your 12-year-old brother never swap Word documents or games with friends? But then who would want to disseminate viruses and trojans, they serve no purpose, right?

A couple of sites I have used...
I have done some Linux tutorials and the sites I have utilized the most have been Rootprompt.org and LinuxSecurity.com. Rootprompt has alot of excellent "essays" on lots of different topics relating to Unix and Linux that can easily be converted to micro-lectures.
LinuxSecurity is more specialized, but when you do get to your security lecture, their "Reference Card" is indisposable.
Hope this helps some, and keep teaching!

BINDv9, security and damage control
All in all Bindv9 sounds good. Some have been real critical that it will have bugs etc etc, so whats the deal...I dont think there is any major SW out there that has 0 bugs. Especially in
.0 release. If they squash or work around the bugs quickly and efficiently I am satisfied. Monitor the various lists and web sites if your an admin, basically its a job req. I wish it wasn't but then again so do most of the SW developers.
Having said all that I must admit the comment about security being "an indirect goal" by Paul was a bit disconcerting to me too. But then David's comment that it was a "core requirement." Different viewpoints ? Quick damage control by D.C. ? -
Interview with {}
Frank van Vliet, aka {}, was as well the wizard who managed to put an IIS banner on apache.org some months ago.. I'm really curious for his next hack!
Here is an interview on LinuxSecurity with him. -

OpenBSD, bridge & ipf
I'm running an OpenBSD filtering bridge between my LAN and cable modem. Its a 486 33, with 16 MBs RAM. I've had so speed issues, and the logging with ipf is excellent. An ipf howto can be found here. Near the bottom there is a section(B.2?) on how to work with bridges.
