Why is Linux secure?
"Linux is so secure.
There is no virus/malware attack."
Why is this so? Is it coz people dont care to write viruses for linux?
Or is it impossible to write a virus for linux?
Or does it got something to do with the unix like permissions(I dont know anything abt the file permissions of unix)
Always wanted to know abt this. Enlighten me

Re: Why is Linux secure?
What I heard on IRC
Quote:
*nix has always been designed from ground up not to execute code.
Windows has been designed ground up to execute code.

You cannot run anything on *nix till you give it permission to run explicitly.
That's the biggest part. Besides there's lots of points to debate on. You can look at the past topics for the answer. It doesn't make sense to bring up that old beat up topic again and again.

Re: Why is Linux secure?
Being open source, Even if some idle mind does think of making virus for Linux, It won't take long for developers to come up with a solution to fix it.So, yes I do agree that nobody bothers writing viruses for Linux.Why bother wasting weeks in making virus when a virus released in morning will have developers fix it by noon.

Re: Why is Linux secure?
There is ONLY ONE existing virus for Linux and that is Bliss
The funniest thing about this virus is that it has an option to disinfect the files and it does as promised (according to wikipedia).
wikipedia says that it was probably designed to show that Linux can be affected by viruses....blah.....blah.....blah
LINUX CANNOT BE AFFECTED BY VIRUSES.

In addition, many viruses are bug-ridden, and these bugs may lead to system crashes and data loss.

Re: Why is Linux secure?
well,there was a kernel local exploit with vmsplice option.only 2.6.24+ kernels where able to fix that! 
http://www.cyberciti.biz/tips/linux-...g-and-fix.html
well,I tried myself that exploit,and it IS able to gain root access easily 
still,this is a local exploit.
