Understanding PCI DSS Latest Version Requirements

To comply with the PCI DSS latest version requirements, merchants and service providers must ensure their cardholder data environment meets the new standards. This includes implementing additional security controls to protect sensitive information.

The latest version of PCI DSS, version 4.0, introduces new requirements for vulnerability scanning and penetration testing. Merchants must now conduct quarterly vulnerability scans and annual penetration testing to identify and remediate potential security threats.

PCI DSS 4.0 also requires merchants to implement multi-factor authentication for all personnel with access to cardholder data. This is a significant change from previous versions, which only required multi-factor authentication for personnel with administrative access.

Merchants must also ensure their cardholder data storage and transmission practices meet the new requirements. This includes implementing encryption for all cardholder data in transit and at rest, as well as using secure protocols for data transmission.

The PCI SSC website is a treasure trove of information, including the PCI DSS v4.0 Change Summary document, which details all the updates. You can also find supporting documents like the PCI DSS Summary of Changes v3.2.1 to v4.0, v4.0 Compliance Report (ROC) Template, and ROC Compliance Certifications (AOC) in the PCI SSC Document Library.

If you're a merchant, you need to know which requirements apply to your organization. There are four different PCI compliance levels, typically based on the volume of credit card transactions your business processes during a 12-month period. Here's a brief overview of the different SAQ types:

These SAQ types will help you determine which requirements apply to your organization. Make sure to review the details of each type to ensure you're meeting the necessary security standards.

The transition to PCI DSS v4.0 is a gradual process that gives organizations time to adapt to the changes.

The transition period from March 2022 to March 31, 2024, allows organizations to familiarize themselves with the new requirements and update their reporting templates and forms.

During this period, both PCI DSS v3.2.1 and v4.0 will be active, providing assessors with the option to use either version after completing PCI DSS v4.0 training.

Organizations must implement new requirements identified as best practices in PCI DSS v4.0 by March 31, 2025.

The new requirements will be considered part of a PCI DSS assessment and must be fully met for PCI compliance after March 31, 2025.

The twelve requirements for PCI DSS compliance are organized into six related groups, known as control objectives.

Here are the twelve requirements:

These requirements are divided into three sections: PCI DSS requirements, Testing, and Guidance.

Compliance and validation are crucial steps in maintaining PCI DSS compliance.

Formal validation of PCI DSS compliance is not mandatory for all entities, but Visa and Mastercard require merchants and service providers to be validated.

There are three scenarios in which an organization may be asked to show that it is PCI compliant: payment processors may request it, business partners may request it, or customers may request it.

The PCI DSS security standard includes 12 main requirements with more than 300 sub-requirements that mirror security leading practices.

To simplify the validation process, the PCI Council created nine different forms or Self-Assessment Questionnaires (SAQs) that are a subset of the entire PCI DSS requirement.

A Qualified Security Assessor (QSA) is an individual certified by the PCI Security Standards Council to validate another entity's PCI DSS compliance.

PCI DSS compliance involves three main components: handling the ingress of credit card data from customers, storing data securely, and validating annually that the required security controls are in place.

To store data securely, an organization needs to define the scope of its cardholder data environment (CDE) and implement strong access control measures and maintain an information security policy.

Here are the four levels of requirements for PCI DSS compliance:

Annual validation is required for all entities that handle, store, or transmit cardholder data, and it involves completing a PCI validation form and undergoing an audit or external vulnerability scanning service.

PCI DSS Security is a critical component of maintaining a secure payment ecosystem. PCI DSS sets a baseline level of protection for consumers and helps reduce fraud and data breaches.

To achieve PCI DSS compliance, an organization must handle the ingress of credit card data securely, store data securely, and validate annually that the required security controls are in place. This involves three main components: handling credit card data securely, storing data securely, and validating security controls annually.

Storing data securely requires defining the scope of the cardholder data environment (CDE), which includes people, processes, and technologies that store, process, or transmit credit card data. This helps limit the scope of PCI validation and ensures that all 300+ security requirements apply to the CDE.

A Qualified Security Assessor (QSA) is an individual certified by the PCI Security Standards Council to validate another entity's PCI DSS compliance. QSAs must be employed and sponsored by a QSA Company, which also must be certified by the PCI Security Standards Council.

To store data securely, an organization must implement strong access control measures and maintain an information security policy. This includes segmenting the payment environment from the rest of the business to limit the scope of PCI validation.

The 12 security requirements for PCI DSS include encryption, ongoing monitoring, and security testing of access to card data. These requirements are designed to secure the transmission of data, like Transport Layer Security (TLS), and are applicable to any organization that accepts or processes payment cards.

Here are the 3 main components of PCI DSS compliance:

Data security and handling are crucial aspects of PCI DSS compliance. PCI DSS is the global security standard for all entities that store, process, or transmit cardholder data and/or sensitive authentication data.

To handle card data securely, companies should consider using third-party solutions like Stripe Elements, which securely accept and store the data, reducing complexity, cost, and risk. This way, card data never touches their servers, and they only need to confirm a few security controls.

Companies that do need to handle sensitive credit card data must meet each of the 300+ security controls in PCI DSS, which can be a complex and costly process. They must also define the scope of their cardholder data environment (CDE) and properly segment the payment environment from the rest of the business to limit the scope of PCI validation.

To map your data flows, identify every consumer-facing area of the business that involves payment transactions, pinpoint the various ways cardholder data is handled throughout the business, and identify the internal systems or underlying technologies that touch payment transactions. This will help you understand where sensitive credit card data lives and how it gets there.

Here are the 12 security requirements for PCI DSS that stem from leading practices for protecting sensitive data for any business:

These protocols are designed to secure the transmission of data, like Transport Layer Security (TLS), and several overlap with those required to meet GDPR, HIPAA, and other privacy mandates.

Handling card data requires careful consideration, and it's not always necessary to directly handle sensitive credit card information. Some business models don't require it, and third-party solutions like Stripe Elements can securely accept and store the data.

Companies that do need to handle card data may be required to meet over 300 security controls in PCI DSS. Even if card data only traverses their servers for a short moment, they need to purchase, implement, and maintain security software and hardware.

If a company doesn't need to handle sensitive credit card data, it shouldn't. This can whisk away considerable complexity, cost, and risk. Card data never touches their servers, and they only need to confirm a few security controls, such as using strong passwords.

Here are some key points to consider when handling card data:

Office 365 offers robust data security features, including multi-factor authentication, which requires users to provide two or more verification factors to access their accounts.

This feature can be enabled for all users or selectively for specific groups, adding an extra layer of protection against unauthorized access.

Data encryption is also available, automatically encrypting emails and attachments to prevent them from being intercepted and read by unauthorized parties.

Office 365 uses the Transport Layer Security (TLS) protocol to secure email communications, ensuring that data is transmitted safely over the internet.

Regular security updates and patches are also applied to Office 365 to address known vulnerabilities and prevent potential attacks.

These security features can be managed and configured by administrators, allowing them to tailor data security to meet the specific needs of their organization.
