that won't stop a dedicated hacker and/or people who are already connected to the network that may have viruses or other malicious software.....

802.1x is an authentication protocol not an encryption protocol... basically it just adds an authentication server into the mix

and no, that will not save you from a hacker
Kinda meh now...

his main argument would be incrediblely hard to disprove don't you think? One of the linux distro's would have to gain a significant desktop market share, is that going to happen anytime soon? i don't know, wish i knew cause if i did, i would invest in that company

so as long as his "argument" rest in the realm of "unbelievable", yeah i guess it is a valid argument, but to anyone who understands the architecture of both OS's will know how inaccurate it is, and how ignorant it sounds.

i don't know about the rest of you, but linux is given what, a 1% to 3% desktop share, and between 30% to 60% server market share. if i was a real "script kiddie", i would know that most of these guys have no form of "protection" outside of what their OS provides them (i.e. no virus scanner, no malware scanner) and they probably wouldn't be paranoid like most are,so that to me would seem like a seriously untapped market i could exploit if the posters argument was true.
The only reason I say he had a semi valid point is when looking at an OS such as OSX. Up until the past few years Apple's OS market share was paper thin (actually quite comparable to Linux's desktop share at one time) but it has steadily rose to between 5 and 10%. No one can argue that OSX is an unsecure OS, because it isn't. It's built from BSD which is well known for its security and stability. But lately viruses and other forms of malware have been popping up on Macs through gateways such as Flash. Linux is equally susceptible to this type of attack as its not the OS's weakness, its Flash's weakness. Foresee-ably Linux could run into these sorts of issues if their market share continues to increase and hackers start targeting users with adware and spyware (because its usually about money these days rather than harming data).

At the same time, when you get a prompt "eatyourfilesandstealyourinfo is looking for root privileges" you can laugh heartily as you don't enter your password and proceed to find and delete the nasty file.

I don't even think it goes that far does it? By my understanding it defines the framework to build an authenticated connection. It isn't a protocol itself, its just a standard.

well "business class" wireless encryptions are different from the ones labled for home use becaues they use 802.1x to authenticate with a server... so yeah i guess its just a standard like 802.11b/g/n only 802.1x is technically just lan not wireless as thats what its intended use was for and now its used with a hard connection from a WAP to the authentication server...

That won't save you from a truly damaging piece of malware. If I was smart and I was developing malware, I would be targeting /home. What do I gain from wrecking the rest of the system when I can rm -rf (or upload to a remote location ) your precious documents? You can restore the former in half an hour but if you don't back up your documents you could be in trouble.

In reality, the most damaging malware doesn't need root privileges.

Hmm, exploits on Linux wouldn't work the same way. Any file downloaded onto the computer doesn't have execute priviledges, and can't function outside of /home without being given the root password anyway. I take randomizer's point on board though, wiping /home would be enough to ruin most people's day (especially as the xorg config file .xinitrc is there, at least on Arch anyway).

Doesn't stuff like SELinux and AppArmor help defend against exploits?

Not unless you give it execute privileges. User error is largely the reason for the spread of malware on any platform Always RTFS

I'm going with this. Schools are filled with thousands of kids with laptops with google and FF clickjacking addons.

When i was in college the network was more frequently infected than not.
