Here's a pair on very interesting posts from The Security Fix, Brian Krebs' column for The Washington Post. In brief, Krebs discusses why small to medium businesses should consider using a Linux Live CD for all online banking, and he includes a tutorial on how to do it using Ubuntu.

In Part 2 of the column, he addresses some of the responses to Part 1, and explains why strategies such as limited user accounts even in combination with multi-layer security employing passwords, secret questions, and even digitally generated one time access codes may not provide sufficient security when accessing online banking. The presentation is primarily directed at companies with no in-house IT staff as a no-cost, technically simple solution.
