What is PCI DSS compliance?
The Payment Card Industry Security Standards Council (PCI SSC) sets the requirements merchants and businesses need to follow in order to securely process and store customer information for credit card transactions.
In order to decrease the instances of fraud and the chance of data breaches, organizations must follow the global technical and operational specifications set out by the Council in the Payment Card Industry Data Security Standard (PCI DSS).
Adherence to the PCI DSS constitutes a contractual agreement between the enterprise and the financial entities that facilitate relationships with merchants.
The changes to the latest iteration of this standard, the PCI DSS 4.0, are meant to protect cardholder data by keeping pace with new types of threats that have emerged due to the continuous evolution of payment technologies.
How has the standard changed with the release of PCI DSS 4.0?
PCI DSS 4.0 introduces 51 new requirements, which will become mandatory on March 31, 2025.
The updates mirror the ways technology, consumer habits, and payment methods have changed over time, and as a result, the revised standards contain numerous updates aimed at addressing emerging risks within the payment card industry.
Some of the most significant changes include the need for:
Improved security documentation and response
PCI DSS 4.0 mandates that every business processing credit card payments must quickly discover and respond to failures of critical control systems.
Organizations will also need to conduct security awareness training to teach employees about potential vulnerabilities and threats, proactively protecting cardholder data from phishing and other socially engineered cyber attacks.
Additionally, IT teams will need to conduct a security awareness program at least once every 12 months, making updates as needed.
Better internal assessments
Organizations will be required to conduct targeted risk analyses to determine how frequently periodic log reviews should be conducted for system components, and how often incident response personnel need to participate in training.
More frequent hardware and software reviews
The standards require a software and hardware review at minimum once every 12 months to ensure that businesses are using the most up-to-date technologies.
Required multi-factor authentication and passwords
In order to build on authentication requirements, the new standards mandate multi-factor authentication for all users accessing cardholder data, extending beyond administrators.
Additionally, password length requirements have been raised from 8 to 12 characters.
Furthermore, organizations now have the flexibility to utilize dynamic analysis to automate access to resources, rather than mandating password rotation every 90 days.
Automated log monitoring
Constant system monitoring is now mandatory to promptly detect and address any potential security breaches.
Improved key and certificate management
The revised standard requires organizations to maintain a comprehensive inventory of key custodians, cryptographic keys, and relevant expiry dates.
Additionally, organizations must manage an inventory of certificates, including issuance authority, date, and validity period.
What are the key dates for the PCI DSS 4.0 standards to come into effect?
March 31, 2024 marked the retirement of the previous version of the PCI standards (PCI DSS 3.2.1), and compliance with PCI DSS 4.0 became a recommended best practice. After March 31, 2025, they will become mandatory.
This transition period allows organizations the time to implement upgrades to their technology or processes as necessary.
How should organizations respond to the PCI DSS 4.0 changes?
