Sorry, don't trust it and don't like it.

Using it.

Not using it.

Using both it and SUS.

All of which I am already aware of, and much of which we are already
using.  If you read my post about this, then you already know that I'm
using ISS, Retina and Languard as well as the MS KB824146 scanner to
check for patch compliance.

So I'm not quite sure what you point is.

Gary suggested checking file properties and I *assumed* he meant for
every machine.  He has now clarified that he meant machines that are
questionable.

Now, as to whether or not I'm negligent as a
professional...well...opinions are like other things that humans have -
each one is unique.  :-)
