Attached please find an article on frequent password changes and their impact on security. After reading the article, read and respond to at least two of the questions and suggestions below. Initial response - 2-3 paragraphs. Also, please respond to others in the class in a separate posting in response to their posting, so it's clear who you're responding to.

1) Do you believe the author's premise, that requiring frequent password changes may actually decrease security? Why?

2) What attack methods seem to you most likely to break a password weakened as the author suggests? Why?

3) What methods seem to you most likely to improve protection for these "weakened" passwords? What can users and organizations do besides requiring password changes?

Cranor, who before her move to theFTC was a professor of computer science and of engineering and public policy at Carnegie Mellon University,gave aTED talkon it more than two years ago.She contends that changing passwords frequently could do more harm than good. Not because new passwords,in and of themselves, would make it easier for attackers, but because of human nature.She cited research suggesting that, “users who are required to change their passwords frequently select weakerpasswords to begin with, and then change them in predictable ways that attackers can guess easily.”This, she said, was demonstrated more than six years ago in a 2009­2010 study at the University of NorthCarolina at Chapel Hill. Researchers, using passwords of more than 10,000 defunct accounts of former students,
