Network World, 07/23/07. A lesson from an answering machine: the importance of input anchoring in password recognition I recently made a discovery that shows the importance of anchoring the input when trying to match a password. By this I mean that there should be no extra characters accepted either before or after the password (i.e., no extra characters that could be part of the password). Unanchored matching greatly weakens the defense against brute forcing the password. Symantec Security Response Weblog, 07/24/07.
