At UNIX Security: Don’t Believe the Truth, Thom Holwerda makes a rather silly argument that Unix security is no better than the worst of Windows security because the result to the user is the same: his personal files can be damaged by a worm or virus even if system files are more protected.
Neglect and Misunderstanding of Backups
I had a call this week from a client who needed a file restored from backup. I had set them up with DVD-RAM and a Supertar a year ago, and had labeled five cartridges with Mon, Tues, etc. I know that (or thought I knew) they followed this rotation for a while, because I had used the previous day’s backup to restore files for them earlier this year.
