NimbostratusPCI Cipher Set
Can someone provide a good LTM client cipher set that would pass PCI ASV as well as support as many browsers as possible? I know no one can support IE 6-10 due to it not having TLS 1.2 and still be P...
Good morning,
I've read that CBC in combination with TLS1.2 is OK to use in case of PCI DSS 3.1 which will be enforced June 2016. Furthermore, our apps that process Visa and Mastercard payments were PCI-passed just this year with the same string I gave you initially. Without any changes, this will also pass the PCI DSS audit in June 2016. Can you specify which PCI version your scanner is using as the basis? I think youre too much ahead of the time, and those rules are probably not yet enforced at this point. Please clarify if you believe I'm not correct on that.
Nevertheless, to meet the requirements of your scanner, I've come to this string. Give it a try 🙂

natesmith317_18I will try this today! Thank you!!- natesmith317_18It appears my hosted scanner (Rapid 7) is incorrectly listing these as insecure: TLS 1.2 ciphers: TLS_RSA_WITH_AES_128_CBC_SHA256 TLS_RSA_WITH_AES_256_CBC_SHA256 TLS_RSA_WITH_AES_128_GCM_SHA256 TLS_RSA_WITH_AES_256_GCM_SHA384 TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256 TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 I am going to put in an exception and we should be good! Thanks for your help!
- alex100_194614We use Rapid 7 as well and what we found out is they are bumping up the there own requirements to get clients aware for future change in compliance. They kind of had us freak out over the recent scans. But it has nothing to do with current PCI cipher suite requirements.
