What happens on 30 June 2018?

30 June 2018 is the deadline for disabling SSL/early TLS and implementing a more secure encryption protocol – TLS 1.1 or higher (TLS v1.2 is strongly encouraged) in order to meet the PCI Data Security Standard (PCI DSS) for safeguarding payment data.

What is SSL/early TLS?

Transport Layer Security (TLS) is a cryptographic protocol used to establish a secure communications channel between two systems. It is used to authenticate one or both systems, and protect the confidentiality and integrity of information that passes between systems. It was originally developed as Secure Sockets Layer (SSL) by Netscape in the early 1990s. Standardized by the Internet Engineering Taskforce (IETF), TLS has undergone several revisions to improve security to block known attacks and add support for new cryptographic algorithms, with major revisions to SSL 3.0 in 1996, TLS 1.0 in 1990, TLS 1.1 in 2006, and TLS 1.2 in 2008.

What is the risk of using SSL/early TLS?

There are many serious vulnerabilities in SSL and early TLS that left unaddressed put organizations at risk of being breached. The widespread POODLE and BEAST exploits are just a couple examples of how attackers have taken advantage of weaknesses in SSL and early TLS to compromise organizations.

According to NIST, there are no fixes or patches that can adequately repair SSL or early TLS. Therefore, it is critically important that organizations upgrade to a secure alternative as soon as possible, and disable any fallback to both SSL and early TLS.

Questions & Answers

  • Do I need to do anything?
      If you have created a technical integration using the Mondido API, you need to make sure that you use TLS 1.1. or TLS 1.2
