"The other problem is that the Linux Operating System doesn't
receive the same level of support as Windows does. That means that
updates and security packages are released with each new version of
the Operating System (OS), but not as periodic updates as in the
case of Windows XP's Windows Update.
"That means that the user will have to be the one responsible
for checking for the updates instead of trusting this matter to an
organization. So, a user could pass long periods of time without
knowing that his OS has an important security failure that could
compromise his work or even the security of his network."
