Re: Email blocking inbound credit card numbers

Kind of curious. If the sensitive information is in an encrypted attachment does that exclude tossing in the whole email system for review?

If you're a merchant, service provider, or other processor in the PCI chain and you take CCs via email then your entire email system may be considered in-scope by your PCI assessor and the full DSS applies. Which means encryption everywhere, physical access reviews, etc. Generally, even if you use Office365, G Suite, or some other hosted solution, this is non-trivial and non-cheap.

Also, rejecting CCs sent via email might, just might, slowly train a few people to think before they send sensitive information via insecure channels.

Downside is that a lot of numbers can match the Luhn check so false positive rate can be high unless the logic looks for other things.

(I own the PCI compliance program for a Level 1 service provider)

I've noticed something kind of interesting on the mailing lists recently.

Some mail servers are blocking inbound email that appear to contain
credit card numbers.

I can understand restrictions on filtering outbound mail that might
contain credit card numbers. While it's obviously not a good idea to
send a credit card number in email, why would a company block mail that does contain one?
