Report: Diebold Voting System Has 'Delete' Button for Erasing Audit Logs | Threat Level from Wired.com

Auditing logs are required under the federal voting-system guidelines, which are used to test and qualify voting systems for use in elections. The logs record changes and other events that occur on voting systems to ensure the integrity of elections and help determine what occurred in a system when something goes wrong.

"Deleting a log is something that you would only do in de-commissioning a system you're no longer using or perhaps in a testing scenario," said Princeton University computer scientist Ed Felten, who has studied voting systems extensively. "But in normal operation, the log should always be kept."
