a debate at the RSA 2008 conference over the security of
Linux vs. Windows.
"Ford said the difficulty with comparing operating systems is that it's often an apples and oranges comparison, and that "raw vulnerability counts really don't give you a good picture," although they can't be discounted entirely.
Besides, argued Ford, even if Linux has more overall vulnerabilities, these vulnerabilities have traditionally been less severe than those affecting Windows. He defined severity as consequence plus ease of exploitation.
"Every time Windows gets a vulnerability, someone immediately writes a rootkit or a worm," said Ford. Linux, in contrast, has fewer critical issues, he added.
