You have probably been bombarded with information about TLS 1.2. It all sounds very scary, especially when notices threaten your system to stop processing credit cards July 1, 2018 if you have not made the necessary changes. One Step included TLS information in our March newsletter and we recently sent out news briefs on this topic.

However, because there continues to be some confusion on the subject, we thought we would devote another article to try to demystify TLS. At the end of the day, what retailers request is: just tell us what we are supposed to do. So, let us offer a quick summary of TLS and then be as specific as we can as to what is required of you.

The PCI Software Security Council has played a significant part in keeping payments safe for a long time, and now it is taking the steps to retire older encryption protocols. Transport Layer Security (TLS) 1.0 and Secure Sockets Layer (SSL), are no longer considered to be strong cryptographic protocols. The PCI SSC has mandated that by June 2018, retailers and service providers must adopt newer versions of the TLS cryptographic standard. This is a mandated industry change in order for credit card processing to continue functioning.
