There are many different versions of the PCI standard, with the latest being PCI 2.1. However, what are the differences between PCI 2.0 and PCI 2.1? And which one is better for your business? In this blog post, we’ll take a closer look at PCI 2.0 and PCI 2.1, and help you decide which one is right for you.
What is PCI 2.0?
PCI 2.0 is the most recent version of the PCI Data Security Standard (DSS). PCI DSS is a set of security requirements for organizations that handle credit card information. PCI 2.0 was released in April 2018 and contains new requirements for entities that store, process, or transmit credit card data. The goal of PCI 2.0 is to further protect customer data and reduce the risk of fraud. Some of the new requirements in PCI 2.0 include mandating the use of strong cryptography for data in transit, implementing multi-factor authentication for administrative access, and performing penetration testing on a regular basis. By complying with PCI 2.0, organizations can help to ensure that customer data is protected from theft and misuse.
What is PCI 2.1?
PCI 2.1 is the latest PCI standard released by the PCI Security Standards Council. It was released in April 2018 and replaces PCI 2.0 as the PCI standard for new implementations. PCI 2.1 is fully compatible with PCI 2.0, meaning that PCI 2.0 devices can be used with PCI 2.1 systems and vice versa. The main difference between the two standards is that PCI 2.1 adds support for new technologies, including PCI Express 3.0 and 4.0, which offer higher data rates and lower power consumption. In addition, PCI 2.1 includes updated versions of the PCI DSS and PA-DSS standards, which provide guidance on how to secure data and prevent fraud. As a result, PCI 2.1 is a major upgrade to the PCI standard that provides better support for new technologies and improved security measures.
Difference between PCI 2.0 and PCI 2.1
PCI 2.0 and PCI 2.1 refer to the PCI bus standards developed by PCI-SIG. The PCI bus is a standard connection interface used in computer systems. PCI 2.0 was released in 2003 and PCI 2.1 was released in 2004. The main difference between PCI 2.0 and PCI 2.1 is that PCI 2.1 supports a faster data transfer rate of 540 MB/s, while PCI 2.0 supports a data transfer rate of 266 MB/s. In addition, PCI 2.1 supports a new feature called Active State Power Management (ASPM), which allows devices to enter a low power state when they are not in use, saving energy. Finally, PCI 2.1 is not backward compatible with PCI 2.0, meaning that PCI 2.0 devices cannot be used with PCI 2.1 slots (and vice versa). As a result, when upgrading to PCI 2.1, all devices in the system must be upgraded to support the new standard.
Conclusion
The PCI Security Standards Council (PCI SSC) has released a new version of the Payment Card Industry Data Security Standard (PCI DSS), known as PCI 2.1. This latest update includes clarifications and enhancements to help organizations meet the standard’s requirements, including those related to encryption and malware prevention. If your organization is currently compliant with PCI DSS version 2.0, there is no need to panic – you have until June 30th, 2018 to migrate to PCI 2.1. However, it is important that you begin planning now so that you can ensure a smooth transition.
