“Does NT4 have the worst security of all operating
systems?”
“Is there a trend here? Yes, actually there is. Microsoft
operating systems, especially NT, has more reported security bugs
over the last two years than any other operating system. You can
see it for yourself in SecurityFocus’ just released statistics on
how many vulnerabilities associated with each of operating system
and platform is in their database for these last three years.”
“SecurityFocus is careful to point out that there study has many
flaws. Those include that there is no weighing of the seriousness
of any given problem. A fundamental and devastating flaw, like an
easy way to gain root access on a Unix system, is given the same
value as a program revealing more than it should about its
operating environment. In particular, it emphasizes that its
numbers should “not be taken to imply that some particular
operating system or application is more or less secure than another
one.” Still, the sheer numbers lend empirical evidence to what
most security experts have learned over the years.”
