i have been having this question in ma mind for a long time.. but havnt found a acceptable answer to it. So fellas.. here it is --> Any GNU/Linux distro is an OperatingSystem consisting of the linux kernel written by Linus Torvalds and mostly free apps which make up the whole distro. And as its under the GNU licence, thus its completely free and is open source sw( we can modify it if we want and get a deeper knoledge about how a program works). Now the the main question is.. if linux as a whole is open source and any one can download the source of the kernel as well as other apps.. then why dont we see uber ammounts of viruses evry single day... why a linux user isnt afraid of opening any email attachment. Why thousanad and thousandz of security patches arnt released every month? Well hacking, cracking, exploiting and defacing any linux box should be relatively easier than a win box as windows is a closed source os while Linux is completely open to any one interested!... Why do servers run on linux when they r sure that the distro they are running , its whole dissected anotomy is just a download away... Just cant solve this equation. So OPEN Brains.. do you have an acceptable answer to my query? P.S. And please no Mass Bombing Theory or sumthing like that.. i want the ans from the tech aspect of it... and not jus any logical theory.
