Issuing banks are not required to undergo PCI DSS validation, although they must secure sensitive data in a PCI DSS-compliant manner. Acquiring banks must comply with PCI DSS and have their compliance validated with an audit. In a security breach, any compromised entity which was not PCI DSS-compliant at the time of the breach may be subject to additional penalties (such as fines) from card brands or acquiring banks. PCI DSS v4.0 recognizes the evolving technology landscape and the need for flexible and scalable security measures.
While MFA is not a mandatory requirement for all users, it’s crucial for administrative accounts to add an extra layer of security beyond just passwords. Getting an organization, especially a small business, up to PCI compliance can be an intimidating task. The benefits of safeguarding cardholder data, however, far outweigh the cost of implementing and maintaining the compliance requirements. The standards originally applied to merchant processing, but were later expanded to encrypted internet transactions. Those requirements, known as the Payment Card Industry Data Security Standard (PCI DSS), are the core component of any credit card company’s security protocol. The PCI 3-D Secure (3DS) Core Security Standard defines security requirements to protect environments where specific 3DS functions are performed, to enable secure consumer authentication for e-commerce and m-commerce purchases.

For this, ensure all users have the right amount of privileged access to data and applications. Adopt the principle of least privilege (POLP), which states you should only provide a user with the minimum level of privileged access needed to perform their job duties. A core component of this requirement is limiting potential vulnerabilities by deploying critical patches and updates to all systems, applications, and endpoints. PCI DSS requires companies to deploy antivirus software from a reputable cybersecurity provider on all systems commonly affected by malicious software. This applies to all endpoints — even those that may not be used to process or store cardholder data, since malware attacks can originate and spread from any device.
Tokenization replaces sensitive cardholder data with a unique, nonsensitive identifier called a token. The original cardholder data is securely stored in a centralized, protected database, while the token is used for processing transactions. This PCI DSS standard reduces the risk of data breaches by limiting the exposure of sensitive cardholder data in the payment processing environment. In the event of a security breach, attackers only have access to the tokens, which are useless without the corresponding original data. PCI DSS v4.0 aims to strengthen payment card data security by emphasizing risk-based approaches, simplifying requirements, enhancing flexibility, and promoting continuous security monitoring.
A guide to PCI compliance
- Continuous monitoring helps identify potential security threats, unauthorized access, and policy violations in real-time, enabling swift response to security incidents.
- Assessing and validating PCI compliance usually happens once a year, but PCI compliance is not a one-time event—it’s a continuous and substantial effort of assessment and remediation.
- The most recent version of PCI DSS was released in March 2022 and is referred to as version 4.0.
- PCI DSS v4.0.1 is the latest set of requirements and it mandates several key aspects of password management, including complexity, frequency of changes, password history, lockout mechanisms, secure storage, and user education.
- This applies to all endpoints — even those that may not be used to process or store cardholder data, since malware attacks can originate and spread from any device.
Other PCI Standards are intended for developers, technology vendors, and solution providers wishing to demonstrate that their product or service was designed with security in mind and meets a defined set of security requirements. These standards support the validation and listing of products and services that meet the standard and validation program requirements. Provide ongoing security awareness training to employees to ensure they are familiar with PCI DSS requirements, the organization’s security policies, and their roles and responsibilities in protecting cardholder data. Creating and maintaining comprehensive documentation is essential to demonstrate the organization’s compliance with PCI DSS requirements. The documentation should encompass security policies, procedures, network diagrams, data flow diagrams, risk assessments, incident response plans, and training records. If your business model requires you to handle card data, you may be required to meet each of the 300+ security controls in PCI DSS.
Establish processes for regular review and updates of security controls, as well as ongoing monitoring of system components and access to cardholder data. Identify all system components, processes, and personnel that interact with or have access to cardholder data, including network devices, servers, applications, databases, and third-party service providers. By following these guidelines, organizations can maintain a secure remote access environment and reduce the risk of unauthorized access to cardholder data.
Achieving PCI DSS Compliance—What to Expect During Your Engagement
The new version is expected to pci dss stand for place a greater emphasis on documentation and communication. Companies will be required to maintain comprehensive records of their risk assessments, security controls, and monitoring activities. Effective communication of security policies, procedures, and responsibilities within the organization will also play a crucial role in maintaining compliance. PCI DSS v4.0 will introduce new and updated security measures to address emerging threats and technology trends. Organizations will need to review their current security controls and practices and make necessary adjustments to align with the new requirements. This may involve implementing additional controls, modifying existing processes, or adopting new technologies to ensure compliance.
Fraudsters can use stolen credit, debit and gift card numbers to make fraudulent purchases on e-commerce sites. The first step is understanding the extent of your environment where Cardholder Data is stored, processed, transmitted as well as the people, processes and technologies involved in doing so or that could impact its security. This sets the groundwork for what assets should be involved in the PCI DSS compliance process.
