The most recent updates from the Payment Card Industry Data Security Standard, referred to as PCI DSS 3.2, has become mandatory since February 1, 2018. All merchants and service providers who accept credit card payments from Visa, MasterCard, Discover, and American Express are concerned. The goal of this regulation is to offer stronger security measures for consumers and protect them, as well as service providers and merchants, against cyber attacks. The first PCI DSS v 3.0 was the first set regulations released in 2015. The next version, PCI DSS v3.1 was then released in 2016.
New standards to prevent security breaches
The latest standards have been set to reduce risks, especially from cyber intruders. With hackers consistently trying to find loopholes and vulnerabilities in the systems, the Payment Card Industry has made it a priority to continuously consolidate their best practices and update their mandatory requirements.
One of the main steps of this process is a self-assessment to ensure that a company is fully compliant with all the established rules and regulations. Penetration testing and vulnerability assessment scans are obligatory every three months. Independent audits, as well as periodic scans, are also required for certain businesses handling large volumes of cardholder transactions.
Certain updated controls and new regulations that are applicable now
Control 3.3 – Changes in wording
Generally, only the first six and last four digits of a credit card number should be displayed. Yet, if the personnel have legitimate reasons to see the entire credit card number, they are allowed to view it.
Control 3.5.1 – Encryption architecture documentation
This control regulating the use of protocols, algorithms, and keys used in protecting card data, pertains to service providers.
Control 6.4.6 – Verifying PCI DSS requirements on new and modified networks
