Vulnerability assessments are usually made on a specific
program/site/network. As a result, simply throwing statistics like
"18 million hosts were infected with Nimda" doesn't tell you
*ANYTHING* about whether your target is vulnerable to anything, Nimda
or otherwise. On the other hand, *IF* your network contains Linux
systems, Dave Dittrich's estimate of how long an unpatched Linux
system survives may be useful information.
