pr00f Posted August 3, 2017 Report Share Posted August 3, 2017 Last week I wrote about Passwords Evolved: Authentication Guidance for the Modern Era with the aim of helping those building services which require authentication to move into the modern era of how we think about protecting accounts. In that post, I talked about NIST's Digital Identity Guidelines which were recently released. Of particular interest to me was the section advising organisations to block subscribers from using passwords that have previously appeared in a data breach. Here's the full excerpt from the authentication & lifecycle management doc (CSP is "Credential Service Provider"): NIST isn't mincing words here, in fact they're quite clearly saying that you shouldn't be allowing people to use a password that's been breached before, among other types of passwords they shouldn't be using. The reasons for this should be obvious but just in case you're not fully aware of the risks, have a read of my recent post on password reuse, credential stuffing and another billion records in Have I been pwned (HIBP). As I read NIST's guidance, I realised I was in a unique position to help do something about the problem they're trying to address due to the volume of data I've obtained in running HIBP. https://www.troyhunt.com/introducing-306-million-freely-downloadable-pwned-passwords/ https://haveibeenpwned.com/Passwords 1 4 Quote Link to comment Share on other sites More sharing options...
Technetium Posted August 3, 2017 Report Share Posted August 3, 2017 It would be exceptionally helpful if @troyhunt could share anonymized passwords for this purpose. :)))) Quote Link to comment Share on other sites More sharing options...
