DR Radio: A Grown-Up Conversation About PasswordsDR Radio: A Grown-Up Conversation About Passwords

We all know the rules. At least eight characters; combination of lowercase, uppercase, numerals, and special characters; different for every account; changed periodically; and never stored in plain text anywhere, not even on a Post-it note. Those are the golden rules for password management we all know, advise, and (probably) follow... but maybe we're wrong.

Over the past few months, the public has been hammered with data breaches, including those that exposed passwords. Security experts have been thrust into the public eye, in newspapers and on television, urging, begging, and warning users to improve their password practices. Yet Cormac Herley, principal researcher at Microsoft Research, says that it's time to stop putting all the responsibility on end users -- time to stop the blaming and shaming. Not only is following the rules too difficult, says Herley, but it isn't even worth the effort.

Herley's recent work on passwords, with Dinei Florencio and Paul C. van Oorschot, includes statements like "a [password] portfolio strategy ruling out weak passwords or password re-use is sub-optimal," and if the IT department doesn't do its job well, "there is no attack scenario where the [user's] extra effort protects the account."
