Deadline for Better Encryption on Payment Systems Pushed Back Two Years (pcisecuritystandards.org)

An anonymous reader writes: The Payment Card Industry Security Standards Council (PCI SSC) has announced (PDF) that it will push back the mandatory implementation of TLS 1.1+ encryption, over the very insecure SSL 3.0 and TLS 1.0 protocols, subject to POODLE attacks. PCI SSC cites "complications" that may come from dealing with EMV chip&PIN cards in the US, the new mobile payment platforms, and browser upgrades for the insecure SHA-1 algorithm.

  1. Email clients are the weakest link by stevel · · Score: 3, Informative

    I run an e-commerce store and have to deal with PCI compliance. We don't store credit card details, but the info passes through our server. The June 30, 2016 deadline to drop TLS1.0 was a big headache, made worse by the "Trustwave" PCI checking tool (mandatory from our payment processor) failing us as of July 2015 for not dropping TLS1.0, but I could submit a remediation plan every three months to defer it.

    I did a bunch of testing to see what broke if I dropped TLS1.0. On the web browser side, MSIE10 wouldn't like it, but other, reasonably current, browsers were ok. What surprised me, though, was how many email clients simply stopped communicating with our server if I turned off TLS1.0 for SMTP and IMAP. It's been hard to find details on which clients support TLS1.1 - and perhaps there's some aspect here I'm missing - but this to me is the bigger problem than the web service. (Even though we don't use email for sensitive info, if TLS1.0 was enabled on ANY port, we fail.)

    I'm glad to see that this deadline was pushed back, as it was giving me heartburn.
