Gentoo rsync Server Compromised [updated]
costela writes "LWN points out that the Gentoo project
fired out an alert about one compromised rsync server." From the message itself: "However, the compromised system had both an IDS and a file integrity checker installed and we have a very detailed forensic trail of what happened once the box was breached, so we are reasonably confident that the portage tree stored on that box was unaffected." Update: 12/03 22:54 GMT by T : One more damage report: gibson writes "The Free Software Foundation recently discovered that its software host site was compromised a month ago. The compromise appears to be the same as the recent attacks on the Debian servers. The site is shut down until Friday while they install replacement hardware and verify the authenticity of the hosted source code."
who didn't see this coming? I use gentoo and i figured it was a matter of time before someone did this. I mean haveing a central tree is cool but it does make it more of a target for attacks. I am however glad to see that they took precautions.
A conspiracy theorist could have a field day..
Now where did I put my tin-foil hat?
IANAH (hacker), but isn't the first thing you do when you break into a system to 'fix' the logs?
How can they guarantee the tree hasn't been affected? Compare it with another copy?
Is it even a linux box? Just because it's part of the gentoo rsync respository network doesn't mean it's running gentoo, or indeed linux.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
Either hackers have decided they *hate* OSS (not likely) or someone is putting up a purse trying to damage the OSS communities security image.
Quack, quack.
I just threw away my tinfoil hat and made a new one out of steel. With a spike on top.
Once is happenstance, twice is coincidence, three times is some one playing silly buggers.
(Kernel.org, debian.org, gentoo.org - all in the same two months?)
Beep beep.
They haven't had a break in two weeks!
Any bets on which major distro will be next? Better yet, instead of point spreads on professional sporting events - Vegas should be taking bets on which distro (or well established free software org) gets rooted next...
First Debian, now Gentoo... Slackware perhaps? Maybe install a spam-bot on a knoppix image?
The kernel exploit was a local one. Evidence has shown that the exploit used against the rsync server was remotely exploited. Good thing that if anything had happened (which nothing has shown up yet, according to the #gentoo-dev channel on FreeNode), it would have only affected about 20 users. Still sucks that there's an exploit at all though.

"How come we never hear about breakins [at windowsupdate.microsoft.com]..."
Because we wouldn't have time for all of the other news.
Do not look into laser with remaining eye.
... they DO have records of what was done and were able to isolate it pretty quickly. IMHO, that's probably saved them a lot of trouble.
Whether it's because the cracker was sloppy or inexperienced, or because the Gentoo team have good server security, I can't say - but it seems they were pretty lucky compared to Debian.
What baffles me is why crackers go after targets like this. I can understand anticapitalist stuff, but my intuition says someone trying to crack a *nix server and damage a distro must have detailed knowledge of *nix systems - and is therefore likely a user of an OpenSource operating system.
Is that guess a little too far off base? If so, what's your take?

break in to Debian, it was notices within 24 hours. Break into Gentoo, noticed in 1 hour. Break in to Microsoft, not noticed for MONTHS.
To those who aren't intentionally trying to troll.. and computer journalists;
Yes, Linux servers can be compramised.
No, the sky is not falling.
No, it's not the end of Linux or open source.
Luck favors the prepared, darling.
Now consider what would happen if the Windows update service was compromized and hackers managed to get past Microsoft's tight security. These update servers could be used for WMD's (Windows Massive Disruptions)...
From excellent karma to terible karma with a single +5 funny post...
I'd like to see at least one credible report of a breakin at Windows Update. If someone can provide one you will forever earn my eternal respect.
Leading to the hacking machine? Fixing the compromises on major linux servers is one thing, but why has nobody mentioned finding the perpetrators?
Anything in these logs on the source of the hacks? Probably another hacked machine, but perhaps it can be traced to a source.
Also, in any package that were compromised or attempted at, what is being inserted? Perhaps we can use it as a honeypot to catch a hacker?
Perhaps 2.4.23 should have a kernel allowance for a log that tells when somebody was trying to use the =2.4.22 exploit (or does it)?
I needed to upgrade my kernel and I'm guessing that by the now deathly slow speed of kernel.org, I wasn't the only one that remembered its time to get the latest stable. There should be a new name for this effect.
It's just inevitable that a high-profile Gentoo server got broken into. I use Gentoo for my desktop, but if I were in a business environment, I'd stick with Redhat or SuSe. Gentoo has always been an enthusiast's distribution. I personally hold Gentoo and Debian in as high regard as one another, and Gentoo is just my personal preference. Both have excellent package managers. Behaving a as a Zealot, whether for Debian, Gentoo, Slackware, or for a religion just makes you look like a blind fool.
no, its news because a very popular linux dist has been hacked which could effect a lot of people. that = news
damn microsoft bashing wannabee
Leads? I'll just check with the boys back at the crime lab. They got 3 more detectives working on the case. They got us working in shifts!
-The Big Lebowski
Seriously though, I would hope that organizations like Debian or Gentoo would have the brain power and tech resources to find a few leads that results in arrests. But why do I doubt that anyone will ever be arrested for any of these types of attacks?
IANAH (hacker), but isn't the first thing you do when you break into a system to 'fix' the logs?
Yes, but I think SOP would be to do a little Jedi handwaving "There was no breach". So if they have a good forensic trail, it's either a) real or b) fake. But why create a fake one, if they could have erased it properly? The only reason would be to hope that the box would be apparently fixed, but in reality still rooted. However, as the article said, after the investigation is done it'll be wiped and rebuilt, which is how it should be.

also because there's something there to comprimise. If I crack gramma's win98 machine, there's not a lot I can do with it except use it as a relay to attack spamhause.
Do worms count as a comprimise? I can't see any possible way that you couldn't count them, and I can't see any possible way that linux would have more comprimises in a year than any of the latest worms would generate in a month.
There is no sure thing in security but there is a simple step to make things a bit more reliable for logging.
If you really have a serious system where you want detailed logs you keep the logs for that system off that machine. Sure the machine that is logging could have been comprimized as well but that is twice as much work. Now you have to hack the machine but also the logger to erase the intrusion event.
In fact one of the things I've seen done is that events are logged on the machine and the logger. The idea was to provide not only redundant logging but also provide a front for hackers. A hacker would see the local logs and be too busy doctoring up those logs to check to see if there is an external logger.
In any event, the logging Gentoo did looks complete enough. They claim only 20 users did a sync against the server during the hour it was online and comprized.
PS, full props for the Lebowski quote!
Luck favors the prepared, darling.
You're not likely to hear of it if one happens, as a general policy large companies a don't disclose such information to the public. Even the small-ish place where I work wouldn't.
We're sysadmins, to us, data is protocol overhead.
This would be fine assuming no software was emerged, if one of those 20 happened to 'emerge -u system' and there WAS packages amiss, that would be bad and not cleaned up by an emerge sync.
Would be a good thing to see if notifying those 20 people was possible.
Anything is possible given time and money.
Why not?
You take the keys of the developers [or even a cvs key] and then sign all the emerge files. There are only like 2000 new ones a day so at about 50ms a signature [for a really slow box] that's only 100 seconds of time [two minutes not much].
That way if the end user downloads compromised emerge files they could detect them.
Damn... I'm like a genius.
Someday, I'll have a real sig.
One of the servers that makes up the rsync.gentoo.org rotation was compromised. This box is not an official Gentoo infrastructure box and is instead donated by a sponsor. The box provides other services as well and the sponsor has requested that we not publicly identify the box at this time.
While it may run Gentoo, it is not stated as such, and could be very well be something else.
Get a free ipod.
To correct a few misconceptions in the previous comments.
It was not their server that was compromised, just a third party server in a round robin rotation. They don't own it, they don't maintain it - just someone else who donated server space.
The primary or master server is not accessible to users, it was not compromised, and so none of the original source files had a chance to be changed.
Only the 20 users that synchronized to this server even have a tiny chance of getting bad files. Having everyone sync now that this server is out of the rotation will immediately fix the problem.
Full disclosure 24 hours later. I give them a lot of credit for such a quick response and disclosure. This is very, very minor.
~J
Only 20 people sync'd with this server within that hour it was compromised...not a big deal, expecially when the compromise did not touch the portage tree and was mearly a rootkit install and some logs edited...not to mention it is a donated server used for other purposes, the attacker might not of even known it was used for Gentoo rsync...
But the server is down and will be scrubbed and re-sync'd, just to be safe
"Some things have to be believed to be seen." - Ralph Hodgson
facts are tricky like that:
"We don't know how many total servers the numbers were gathered from or what percentage of those servers is Linux vs. Windows, etc. It is safe to say that these results are true for the servers they monitor, but the percentages may not be true for all servers across the globe."
while there certainly exist a large number of linux machines that have been compromised, i can't imagine the number of infected linux machines is anywhere near that of the win32 systems infected by blaster/welchia/code red/nimda/sql slammer/klez/dumaru/sobig/etc. in the same time frame. i suppose the counting in this case depends quite a bit on the counter's definition of "compromised."
So I've been lurking around here long enough to spot certain trends. (Warning: generalizations ahead)
OSS advocates love to hate Windows
OSS advocates gloat when a new hole turns up in Windows
OSS advocates point to the number of worms, virus, etc in Windows and say, "Never us"
Then several OSS distros have a security breach in a short space of time.
OSS advocates respond with "Must be a conspiracy against us by some evil entity", "Hey, look how quick we caught it", "It would have been much worse with Windows".
Time to face facts gents. Windows is attacked FAR more than OSS. Why? Well, yes, it is full of holes. But downtown Philly is riddled with abandoned houses with no locks on the doors but they never get broken into. Why? No value in doing so. Not enough damage, headlines, misplaced glory, etc. But the main reason is that it is the dominant OS out there. I fear that we will see more and more attacks against OSS with it's growing popularity. If we all get our wish and 'nix takes over Windows dominant market position and is running on 90% of desktops, you will most likely find it a target for constant attacks like Windows has now.
We all know in order for 'nix to make it to the desktop, it has to become WAY more user friendly. Can't have Grandma trying to recompile the kernel now can we? User friendly unfortunately translates into users being able to do things that comprise security. Like opening attachments, downloading Trojans, etc. Then the great security built into the OS goes right out the window. no pun intended).
So before you all start crying about conspiracies, et al, just remember that we all may be victims of our own push to make the 'nix stuff more popular. By bragging about how secure it is, we just may be attracting the type of attack that is more sophisticated then the script kiddies attacking Windows. I imagine it's cool to brag to your friends that you broke into a Windows box. I imagine it's much cooler to brag that your rooted a Linux distro. Badge of honor and all that.
The opinions expressed here are not mine, but those of these dang voices in my head.
Simply put, Gentoo didn't own the machine, there are lots of "rsync" servers that people use (like web sites, but used for downloading files only). Because the people who run gentoo don't own the server, they aren't responsible for it. All this leaves me with a very uncomfortable feeling. I have some websites running on linux servers (not mine) from rackspace providers. Should I be worried ? No! Gentoo is really a desktop OS. Your websites will not be affected. In fact from the sounds of things no one will of been affected, just the 1 server.
MAN! if the terrorists are in on this, and since this is obviously a microsoft plot microsoft must be terrorists....... AH second hand information, "i know this guy who knows this guy who works at this company and this is what he said" :) by the way i know this is a troll but it's one of the funnier things I've seen today
I though the Gentoo Zealot response would be:
:D
"Ah, but Gentoo's root exploit was compiled from source, so Gentoo got rooted 0.000000124% faster than Debian!"
Ah well, I like Gentoo myself. It is quite fun.

With apologies to Torne, from whom I stole this quote.
I am one of many. My idea is not unique, nor do I expect my voice alone to sway you. I speak in a chorus of opinion.
Comparing WindowsUpdate to the portage tree isn't quite an accurate analogy. Portage is distributed to a number of 3rd party donors/volunteers who look after the servers. It's not like the Gentoo team looks after them.
A better analogy would be to ask how many times the update sites for RedHat, Mandrake, etc. etc. has been broken into, since the main update locations are kept up by their respective corporations. I have no idea what the answer to this is.
IDS is placed on a system to follow an attack. Audit trails on sensitive machines reveal all commands executed, to the detail you desire.
Here is the point. Bruce Schneier says that the important part of security is not that you were compromised, but rather that you can react within a time frame to keep the damage to acceptable levels. If you can tolerate having your system compromised for weeks, don't invest in a lot of security. The short response time (2 hours at 11pmEST) here indicates that the Gentoo administrators care about responsiveness enough to check on it frequently.
When the CVS gateway to Bitkeeper on the Linux Kernel was compromised, the developers of Bitkeeper were able to show that they care enough about security that they invested in many checks and balances that caught the error immediately. Since then, Bitkeeper developers, interested in protecting their good reputation (which is VERY difficult to replace), are considering even more drastic measures.
As a bonus, some cracker spent a good few days or weeks writing this exploit. We get to keep it and deploy the solution with little hassle. And the compromised system, because good security practices are in place, was mitigated to minimize damage.
Read Schneier's book Secret and Lies to find out how security is really a process. Yes, I know it's a plug, but I just thought the book hit-home to the real point - "When, not if" you get compromised.
Several other posts here hint that the world will think less of Linux for this. False. True CIOs should see that Linux has the tools to completely identify and contain attacks. Every CIO knows attacks cannot be stopped, but rather they must be contained to acceptable levels.
So anyways, they did not count (most) worm incidents, as they would happen on non-server windows machines.
That does not mean that Linux boxen should not have better default security settings, of course.

Good luck catching your buglar. I want to know how to patch my box.
"Learning is not compulsory... neither is survival."
--Dr.W.Edwards Deming
Let's face it, no OS is 100% secure. Operating Systems that are more secure than others still need to be on their toes. One security exploitation on a Linux box can still be as dangerous as a thousand (an underestimated ratio I'm sure) exploitations on a Windows box. However, I will take the body of security knowledge surrounding an OS to be as valuable as the initial security design principles in the OS in the first place; with that in mind, many Open Source OS's come out looking pretty good. I trust the Linux community to grind down and fix security problems and not sit around and emphasize the numerous security in a Microsoft product. If you're concerned, then help out developers by testing the software and reporting bugs. You could even code a few patches yourself, that being the whole point of community-based development.
Whether or not there is a deep and dark plot to root big Linux boxes is irrelevant. This is another opportunity to demonstrate the Open Source community's response to security issues to the rest of the computing community. If the heat is really on and this is not just another artifact of news gatekeepers getting over-zealous on a trend, then so be it. It is an opportunity to review and evolve Linux's security as well as the security processes that surround it.
One of the things I admire most about Linus Torvalds is his steadfast commitment to the quality of his product. It is a commitment that is focused on constant improvement, not PR damage control. I'm sure the real security guru's are sitting with a bit more comfort knowing their servers are running Linux.

For all of you that are curious, this isn't a BSD troll (although it could be...).
My point here is that whenever a larger *NIX server is broken in to, there are ALWAYS people that comlain about "the insecurity of *NIX". Well, when ONE large *nix server is broken in to, it makes it to the front page of slashdot, whereas blaster/sobig/etc usually get a story or two.
This is where the quote above comes into play.
Linux might look insecure, but that's because we usually hear about breakins on a 1 server basis. When we here about Windows, it's usually in the HUNDREDS OF THOUSANDS (if not more). If there was a slashdot story for every one of THOSE servers, then it would appear the way it actually is.
Not Free(as in beer). Free(as in "I'm free to beat you over the head for being a dumbass")
Is it not possible at all to secure a server ?
The old adage goes something like: the only safe computer is unplugged, encased in concrete, and buried at a radioactive waste site.
It sounds like the admins at this place were doing a good job, hence catching the break-in in 1 hour and having a log trail of what happened. The interesting thing will be when they find out the exploit used to get in. The Debian rooting caused a new kernel version, because the flaw was found to be in the Linux kernel. Hopefully we'll soon know what weakness the attacker used in this case, and another hole will be filled.
Security is never perfect. You worry based on your risk level. The defence department is not allowed to put any classified information on a public network for that very reason. This is why Slashdot panics over Internet-Ready weapon systems, and electronic voting: they put something significant or dangerous at risk. On the other hand, if it's just your blog and photo album, then are you worried about a compromise?
There's also exposure level. There are hundreds of people trying to break into Microsoft, or the DoD. The very best people will put their best effort into it. Smaller sites mostly get script kiddies. The tools they use are based on known exploits, which have probably already been patched. So unless you really offend someone, patching will keep most of us out of trouble.
This break-in will cause one more security flaw to be fixed, and the world will be a little bit safer, for now.
... did whoever did this steal any of our source code?

If you buy the idea that spammers are behind many of the recent worm/viruses, designed to turn machines into spam zombies, it's also probably reasonable to conclude that Windows isn't exactly a reliable platform to trojan; I'd bet a lot of trojans fail to infect properly simply due to Windows problems. And then there's the problem AV software, many of the machines being behind firewalls/NAT and being unreachable. And then there's people turning their PC's off when they don't use them.
OSS machines, however, are a much more reliable computing environment, meaning that any trojans are actually like to work, and work well. And I'd also wager that many OSS machines are used AS firewalls or bastion machines, and if compromised are easily accessable for spamming or use as stepping stones to other machines. And many of these machines are always on -- you don't have to worry about lack of reliability from disabled machines.
This makes more sense to me than any other conspiracy.
http://savannah.gnu.org/statement.html
On December 1st, 2003, we discovered that the "Savannah" system, which is maintained by the Free Software Foundation and provides CVS and development services to the GNU project and other Free Software projects, was compromised at circa November 2nd, 2003.
The server wasn't actually running Gentoo Linux from what I have read.
FuckTheFuckingFuckers.com - Post your th
Since Gentoo doesn't have a "THE" source code repository, I'm afraid you've got some facts to get straight, Herr Coward.
The mirror had read-only rsync access to Gentoo's primary (US) mirror. Even if the tree were compromised, the changes could not propagate into the main tree. For that, one would require CVS access to the CVS repository, against which the primary rsync server is synchronized.
This was only posted as a matter of keeping our user community, and the OSS community as a whole informed.
Also, I believe the announcement gave mention of it, but the Portage tree on the primary mirror was re-created from the CVS repository immediately upon being notified that a mirror was compromised. Within 30 minutes, every Gentoo rsync mirror had a fresh copy of the tree automatically (as stated by Gentoo rsync mirror policy, mirrors are updated every 30 minutes in order to remain on the official rotation).
Sorry for the confusion, all, but there's really nothing to see here. But it was good clamouring practise for when/if a real Gentoo server is compromised. ;)

During an oddly-underpublicized security Webcast Monday, Microsoft revealed that hackers subject the company to 2500 to 3000 electronic attacks every day, or over 100,000 a month. Yet despite this massive number of attacks, the last successful intrusion occurred over three years ago, during the infamous October 2000 security breach. But the software giant says the biggest security risk to the company isn't external electronic attack of its Web properties, but rather its huge fleet of mobile workers and partners--some 60,000 strong--that access the company's 175 remote access points on a regular basis.
We've taken a deep look inside Microsoft to see how we can improve security at every level," sad Mike Nash, the vice president of the Security Business Unit at Microsoft, during the Webcast. "A lot of the technology we use Microsoft applies directly to [customers'] work."
Microsoft revealed some other interesting statistics during the Webcast. The company uses Computer Associates' eTrust security management suite to secure its networks. It uses two-factor authentication (user name/password and smart card) to better secure its intellectual property.
"Sufferin' succotash."
I love it.
I've pointed out before that Windows is way more widespread than Linux, and so is more attacked and vulnerable, but then zealots come on and say Apache is the most-used on the net and yet not the most breached. But to this, it's already the most-breached operating system.
Hoot and holler about the reasons all you want, but them's the facts.
We REALLY, REALLY need to stop with the "Linux is invincible, Windows sucks" attitude. It's flat-out not true, and it's severely holding the community image back in the minds of the rest of the rational computing world who just uses what they use to get the job done and don't treat operating systems like religious belief systems.
"Sufferin' succotash."
A Netcraft search for rsync.gentoo.org shows more than one server. Two of them run Gentoo, two run Red Hat, one runs Debian, three run unknown Linux, and one runs FreeBSD (some of the servers are listed twice). There are more servers (14, if one is to believe 'host rsync.gentoo.org|wc -l'), but Netcraft is only interested in those with web-servers.
Two compromises, both cought within an hour and with no (absolutely none) adverse effects on the users - there is just not much room for improvement here, this is what good security is.

"...not a big deal..." because only 20 people used the server in an hour.
but there is the possibility it could have happened to a server with much more throughput. That is worrying. Dismissing this as not a big deal is a slack attitude to security, be it a part-time server or not.
karma karma karma karma karma chameleon, you come and go, you come and go.
There are several methods with which you can gain access.
/etc/passwd by passing certain variables to a script run on a webserver, and from there you can attack user accounts. Also certain scripts have the error of allowing you to run system binaries, which again can be exploited. Always run your database daemon and your httpd in a chroot environment, with minimal access to system binaries, and always as a non privileged user.
1. Buffer overflows, or out of bounds issues, with services running on a server, eg ftpd, httpd, sendmail, bind (dns). This is where it is discovered to be possible to send malformed data to a service which the service is not expecting and wont deal with naturally. This sometimes results in the ability to send it some executable code which is read straight into memory and executed. Very easy to code around, very easy to detect, fairly easy to detect and very easy to exploit. This is the sort of attack that normally occurs against MS Windows et al, although sendmail, bind and various ftpds (wu-ftpd) have a reputation for being full of them.
2. Password sniffing. This is where someone sits between a user and their box and sniffs network traffic, etiher getting a password unencrypted (normal ftp login, pop3 etc etc) or a weak hashed. Fairly easy to do, and you have a login to the system when you do. Not normally seen these days as ssh is used, and you should always have a seperate restricted user login for other services which do not encrypt passwords (imap, pop3, ftp etc).
3. Issues with web scripts, that sometimes allow you to insert data into a database which the owner doesnt want you to do (or get a copy of his database) via SQL Injection attacks. Also it has been fairly common in the past to be able to get a copy of
The biggest problem these days is that a lot of services run as root, because they need to to bind to ports lower than 1024. This was done so it allows you to "trust" services on those ports as being proper ones, rather than ones run by a normal user. A way around this is to run all services as a standard user, on port ranges above 1024 and bound only to IP 127.0.0.1. This means that your services are no longer on the standard ports, but you can get around this by using ipfilter, pf or another port fordwarding tool to forward all traffic on external priviledged ports to the services on 127.0.0.1, allowing you to run services as non priviledged users while retaining compatability with the outside world.
It is VERY difficult to secure a server to near 100% levels, although you can get pretty close if you want to constantly be working at it. The goalposts change rapidly from day to day, and it can be hard to keep up. If you only run the services you really need, in chroot environments, and ensure that those services are well known services (apache for httpd, exim postfix or qmail for smtpd, pure-ftpd or pro-ftpd for ftpd, DJBDNS or bind 9 for dns) then you can be assured that there are trusted people looking at the source for exploits to fix as well as the untrusted people doing the same to exploit.
Good logging firewall rulesets, an IDS (intrusion detection system), and a remote logging facility are all plusses in the fight.
Cars are built out of steel, not glass. Glass is a very strong material. But hit it with a hammer and it shatters. Steel just gets dented.
Gentoo had "ductile" security. They were able to limit the damage because they had some kind of Tripwire/mtree-like program running on the inside. Given the speed of the response, my guess is that they had a response plan ready to go.
The lesson is that measures to limit the damage from a break are as vital as measures to prevent breaks in the first place. Fire prevention doesn't substitute for sprinkler systems, and intrusion prevention doesn't substitute for backups. You've got to have both.
Really? How does a windows machine being compromised effect me?
Ever looked at the amount of incomming traffic when you're online? Ever considered where the amount of you are getting is mainly comming from?
Unless they get windows.update, I am not concerned at all.
Well, start worring right now. How big do you consider the chance that your vendor tells you about that? They don't even tell you about problem in your OS they know about for months before some exploit is published in the wild.
I do share your concern about trusting the source of your software, but even with these compromises i'd trust Debian and Gentoo more that a big company that has a huge interest in hiding problems like that.
There is no solution to this problem, other then writing all your software yourself. The thing that comes the closed to that, while being still practical, is and open development model where a lot of people are reviewing the source for mistakes and/or malware.
From the Gentoo Altert:
Gentoo realized that they got hacked after one day.
GNU Savannah realized that they got hacked after one month.
It's time to propagate the use of file integrity checkers! They can detect the effects of any new exploit and can't be circumvented (when properly used!).

But I'm glad that there has been so many attacks against linux and other oss projects.
Kernel.org, debian.org, gentoo.org Gnu.org All of them had security holes and now those holes are plugged.
I used to run a few servers. Mostly web-servers, but I had a few for mail and other things. Almost every single one was hacked all in the same 2 month period. I had kept up with updates and I figured I was secure. If I wasn't hacked I would have never known that I wasn't secure and I could have been seriously screwed down the line. It was a much needed eye opener.
I'm just this guy, you know?
Security is so much more then stopping the user at the door. There are always going to be 0-day exploits, which have no patches. The trick with security is mitigating your exposure. Getting root is not a successful hack, keeping it is. So what if someone rooted my box, if I can see it; I can deal with it. These latest big-profile comprises are actually good news because the attacks where not successful. It shows how well Linux can mitigate exposer, and how it layers it security. This is where Microsoft goes wrong with it's lastest methodology towards security. They think putting a firewall in place is all that you need, which is absolutely wrong.
Nothing more, For me to say; About my life, A life of dreams....
I was going to post it here, but the moronic lameness filter won't let me. So you'll need to look at rsync.samba.org.
