Linux servers 'attacked more often'

Online servers running Linux were attacked more often in January than those running Windows, according to a security firm. Linux advocates often take pride in the operating system being more secure than Windows but this claim may have attracted unwanted attention from the hacking community.

An analysis of hacker attacks on online servers in January by UK-based security consultancy mi2g found that Linux servers were the most frequently hit, accounting for 13,654 successful attacks, or 80 percent of the survey total. Windows came in a distant second with 2,005 attacks. A detailed analysis of government servers also found Linux to be more susceptible, accounting for 57 percent of all security breaches. In a similar study last year, Microsoft Windows proved to be more vulnerable, accounting for 51 percent of successful attacks on government servers.

However, the sharp rise in Linux breaches probably reflects a lack of training and deployment expertise rather than inherent security problems within Linux, mi2g officials suggested.

But how often does a linux server actually get taken down entirely from a hack...besides SCO.... ( ) . It occurs to me that windows servers are MORE likely to come down from registry degredation and corrupting it's own files than anything else.

Sorry, but there's more to the story than that.

You mean like the linux server that had the Windows source code on it that was hacked? Linux nuts bragging about how secure the OS is make Linux a nice, juicy target for hackers. That's why they originally focused on Windows... Product with the most attitude gets the attention.

It wasn't an exploit in Linux that was taken advantage of, it was an exploit in their FTP server software that was taken advantage of. If that same software was used on a Windows server it would have been hacked just the same. And in this case it isn't even a fault of the FTP server software, as updated versions and patches had been made available to fix the problem, but MainSoft chose to not use them.

Isn't the linux version of apache like the most widely used hosting method as well?

That to me would explain it right there.
#2.1 YaddaMe on 20 Feb 2004 - 13:58
Apache has 67% of the market, up 5% from last year.
Microsoft, 21%, down 6% from last year.
Sun 3%

You'd think they would at least mention that fact.

Anywho, all are relatively secure if you know what you are doing.... and at the same time, none are hacker-proof.

On a side note, ran across something interesting that I wasnt aware of... while Apache has a clear lead and is expanding it with webservers, Microsoft still hosts more SSL servers (MS 49%, Apache 36%, Sun 3.5%)
#2.2 Faze on 20 Feb 2004 - 14:03
Setting up SSL in IIS5 is particularily easy and it performs quite nicely.
Windows 2000 does have very good certificate handling.

Your first statement makes me laugh. I have been saying this to all the people who claim "Linux is More Secure because there are not as many security vulnerabilities as Microsoft". I also agree with this.

With your second statement, you hit the nail right on the head. If you keep your systems patched, and secure them, you will have less security problems no matter what OS you are running.

I am not saying Linux is less secure then Windows, but I am also not saying Windows is not as secure as Linux.

The main problem is a lot of these so called 'webhosts' get a dedicated server with Apache and cpanel and just leave it running. Never update it, never even look at it. Then their server gets hacked and they wonder why it happened.

Linux by default is much much more secure than windows - but these webhosts who have 25 servers leave all services online such as telnet, SSH on a normal port.

And that is how it should be. If you assume that by putting ftp on, oh, i don't know, port 1984 will make it more secure, you sir, are living in your world

Security through obscurity should never be even considered.

If these Linux companies don't educate people regarding security, then inheritly, Linux is insecure. I dont' care how secure it can be, if people don't know how to secure it, it has more holes than swiss cheese.

Microsoft has Linux beat in this department hands down. By telling users how to secure their computers (Baseline Security Advisor, Windows update, ICF, and so on), keeping the source code secret while doing extensive audits on it, etc, they make Windows more secure.
#4.1 Faze on 20 Feb 2004 - 13:48
In Unix-land security is part of the culture and has been since day 1.
However, what we probably have here is MS admins suddenly having a Linux box pop up in their DMZ and beeing told - "keep this running", without being sent on any training, etc. I talk from first hand experience here...

BTW Red Hat's security documentation is excellent, the RHN can autoupdate machines, just like WU or SUS and the Linux kernel netfilter makes ICF look like a sad apology for a packet filter.

I disagree. When it comes to security, you are saying its the OS's fault b/c the admin doesn't educate themselves? While no doubt running a *nix server is a lil more complaticated of a task when it comes to securing/updating but it's not rocket science. Half start of with an improperly configured server from the get go... so no security update, firewall, etc is going to help them.... these same people would probably foul up their IIS server as well.

Overall, the successful hacks, according to the study, were fairly proportionate to market share... so it's hard to say MS beats Linux hands down in the educating process. This isn't a knock on MS by any means, it just goes to show that there are a group of people on both sides that don't have security as high as a priority as it should be.

I agree with you YaddaMe. As an MS guy my whole career I approached my first Linux server with some trepidation, obviously the 'it's really complex' fud had osmosed in. I was pleasantly suprised to find most parts simple, elegant and logical.

I have to admit I needed webmin to get me started, which I think is a great tool. (No doubt I'll get flamed by a guru who believes text editor or nothing)

That... that's another story.

I am part of these "guru who swear by vi and disses config tools for his own use"

However, for the sake of configuration by non-gurus, a server SHOULD have proper "easy to use" config tools...

I'll never understand why gurus are dissing someone who uses webmin. I mean, it does the job, right? Perhaps it makes them feel 1337er.

Of course, you get to learn more by doing it by hand but still, you know... Nobody's born with knowledge, and graphical configuration tools were built for a reason.

Nothing is secure if you don't take good care of it periodically. You can never get absolute security, you can just approach it.

"mi2g said its study focused on "overt digital attacks" and did not include other methods of intrusion such as viruses and worms. "

Just as well for windows! I don't think it'd be quite the "distant second" had those figures been included. Why don't we try comparing OS's by only looking at virus & worm infections, see which is the most insecure then.

#7.1 darksoul on 20 Feb 2004 - 16:54
i agree with mi2g though a worm is not really a hack the way i think of it. I think of a hack as someone looking to get into a particular machine how ever they can not code looking for a particular vuln. might just be me though

But then, it is still flawed. There is no doubt that more worms and virii are written W32; but then again, W32 is the dominant platform. If *nix was the dominant platform, we'd see the exact opposite of what we see today.
#8 slapnuts_ox on 20 Feb 2004 - 14:18
The problem here is that there are people that think they know linux then there are people that really know linux. The problem is when a large company hires someone which "knows" linux and then find out several weeks later they were hacked due to a security hole which had been fixed months ago but the person which is suppost to be in charge of the machines never updated it. This whole situation all goes back to what I've always said which is that it doesn't matter how secure an OS is, if the person using it isn't properly educated than it becomes vurnerable.

Just a few weeks ago our web hosting provider's box running RedHat got hacked ALL index.html, index.htm home.html and home.htm files were lost and replaced with a defaced index.html file, It was crazy, It appears they didnt patch something that had security problems.
So at the end what? Linux too is insecure as any other OS, No OS will be secure unless users stay on top of security and updates period.
#9.1 Rudzer on 20 Feb 2004 - 14:39
try to explain that to linux fanboys
#9.2 slapnuts_ox on 20 Feb 2004 - 14:49
one could also say try to explain that to windows fanboys.........they can now say well windows was hacked less and its better.
#9.3 PseudoRandomDragon on 20 Feb 2004 - 18:11
There are radical Linux users and there are radical Windows users. Your point?
#9.4 Fanon on 20 Feb 2004 - 19:41
The point is that Linux fanboys act like Linux is the second coming of Christ and that it is impregnable.
#9.5 mr_da3m0n on 20 Feb 2004 - 20:22
The same could be said about some windows users.
#9.6 JaggedFlame on 20 Feb 2004 - 22:28
There are way more Linux users who act that way than Windows users who do.

First of all, where is the PROF? Second of all, if you dig deeper, I'd bet the majority of these hacks are done simply by brute force pasword cracking, LAME admins, or poor firewalling. Which is still a problem, but it least it's not at bad as say, I don't know, worms, bufferover flows, etc.

Just more FUD for the fire.
#10.1 YaddaMe on 20 Feb 2004 - 17:11
I dont doubt the numbers... If you notice, the numbers pretty much follow the the same as market share. There are a boatload more Linux server so of course they're going to be hacked more... just like there are a boatload more Windows installs on desktops, Windows obviously the majority of attacks aimed at he desktops.

Honestly *all* OS's have good security.... the main/primary problem on most exploits/hacks/virii/etc is pebcak, no matter which OS you are talking about.

A dedicated server can be leased pretty cheapy nowdays. Many people that really shouldn't be administrating a dedicated server are going ahead anyways due to the prices... further adding to the pebcak problem.
#11 redFX on 20 Feb 2004 - 15:22
If you notice, they are comparing servers, not desktops.

There are tons more linux servers on the net then windows servers.

Also, dedicated servers are very inexpensive these days. They all come with a management system so you can web manage it.

Most servers getting hacked out there are people who are not admins buying dedicated servers cause its "cheap" and "cool" instead of buying managed hosting. They leave their box on and get hacked. These are the people who have no idea what security means and they are the ones getting hacked.

If you compared companies who have certified or highly experienced system/network administrators, you would probably see that those who run windows servers get hacked more then those who run linux servers.

Just a thught, but has anybody considered that the decrease in hacking incidents on Windows boxes has a lot to do with MS's work on IIS security. IISLockdown and URLScan are pretty slick tools, locking down an IIS5 box is pretty easy these days.
Also IIS6 has a much better design and seems to be pretty solid.

IMHO IIS6 and Apache a both good webservers, I personally lean toward Apache - I'm just saying making an IIS box public isn't the suicide mission it used to be.
#12.1 mram on 20 Feb 2004 - 16:40
Agreed. If anyone wants to see where MS is headed, lets see a vulnerability in IIS6 (only on WS2003). It's a very tight system.
#12.2 Faze on 20 Feb 2004 - 16:52
I would like to give Apache it's dues on this too - it has an excellent security record for a project of it's kind. My feeling is that an experienced Linux/Apache admin could run a webserver that is at least as tough as a Win2003/IIS6 box managed by an experienced MS admin.
My original sentiment stands though - MS have improved IIS A LOT over the last couple of years.
#12.3 darksoul on 20 Feb 2004 - 16:57
i would say almost any system (especially one not in wide use) that was set up and maintained correctly is pretty good
#13 Slugbait on 20 Feb 2004 - 20:06
The most-likely reason hack attacks surged in January was because of the two escalation of privilege exploits discovered in Linux late last year. Once hackers know it's there, they know that thousands or even millions of accessible machines are currently vulnerable. A new kernel was released in January that plugs these exploits, but just as it is with Windows, there must be a physical person to update the machine...and there is a very long and colorful history of how lazy or irresponsible people are when it comes to making sure their boxes are properly updated. Blaster is an excellent example.

Besides, an escalation of privilege exploit is the ultimate crack. It feeds their egos when they're successful.

If theres 20x more Linux machines than MS machines in this pool, then these numbers go the other way.

These numbers are useless and mean nothing without information on the pool of machines we are talking about.
#14.1 Shining Arcanine on 22 Feb 2004 - 03:27
Lets assume Linux has 80% of the market and Windows has 20% of the market. There were 13,654 compromised Linux Systems and 2,005 compromised Windows systems.

20%*4=80%
2,005*4=8,020

13,654>8,020

From a mathematical standpoint, Windows is more secure.

That is flawed reasoning.

The ability and ease in which to compromise an OS is how it is determined whether or not the OS is more secure. Not the sheer number of machines in comparison. If you want to show us a comparison of something, you might as well grab an apple and an orange and tell us that not only are they the same color, but they taste the same, too.

For example, if we were to take the privilege escalation exploit away from Linux and give it to Windows, your formula would still show Linux as less secure. And this could be nothing further from the truth.

Even if Windows had 80% of the market, Linux would still be less secure, simply because of the exploit.
#14.3 Shining Arcanine on 03 Mar 2004 - 00:44
The only reason you don't like it is because it is in favor of Windows. If it was in favor of Linux, you wouldn't be singing the same tune.
