Understanding PCI Compliance: Adapting standards to combat today’s threats

Go deeper into the history, evolution, and importance of PCI standards

Since its creation in 2004, PCI DSS (Payment Card Industry Data Security Standard) has become the global standard for payment data security. The standard has evolved significantly, driven by advancements in technology and the need to address newly identified vulnerabilities through data breaches and forensic investigations. Each version introduces enhanced requirements and controls designed to tackle the changing cybersecurity landscape and improve data breach prevention.

Staying compliant requires organizations to understand these updates and implement the latest security measures, which are essential for minimizing risks, protecting customer payment information, and avoiding the devastating consequences of a data breach.

The role of standards bodies, such as the PCI Security Standards Council, and how they shape the compliance landscape

The PCI Security Standards Council (PCI SSC) is the standards body that oversees and maintains the PCI DSS standard. Its founding members are the major international payment card schemes - Visa, Mastercard, American Express, Discover, and JCB.

As the governing authority, the PCI SSC is responsible for:

1.

Developing and publishing new versions of the PCI DSS standard to address evolving threats and security best practices

2.

Defining the detailed technical and operational requirements that entities must meet to demonstrate PCI compliance

3.

Accrediting third-party assessors (Qualified Security Assessors or QSAs) who can validate an organization's PCI compliance

4.

Providing guidance, training, and certification programs for PCI compliance

It’s important to note: While the PCI Security Standards Council (PCI SSC) creates the standard of PCI DSS, it is the individual payment card brands (e.g. Visa, Mastercard) that dictate the actual enforcement and compliance rules for businesses within their respective networks.

The PCI SSC (Payment Card Industry Security Standards Council) holds significant authority over the PCI compliance landscape. This body develops and maintains the PCI DSS standards and provides compliance validation frameworks. While the card brands, such as Visa and Mastercard, enforce these standards, the PCI SSC plays a central role in driving global security improvements and ensuring consistency across the entire payments ecosystem

Risks & how to streamline compliance

Overview of PCI Standards for Merchants

In brief, the PCI standards establish a comprehensive security compliance framework that merchants must adhere to when processing card payments, whether in-store, online, or on mobile devices. Without PCI compliance, merchants cannot work with acquirers and may incur fines imposed by card brands including Visa and Mastercard.

Types of PCI Standards

Merchants should be aware of various PCI standards, including:

PCI PTS (Pin Transaction Security)

PCI P2PE (Point-to-Point Encryption)

SPoC (Software-based PIN entry) solutions

PCI DSS (Payment Card Industry Data Security Standard)

The implications of failing to comply with PCI regulations can be significant:

1. Financial Penalties

  • Non-compliance can lead to penalty imposed by card brands such as Visa, Mastercard, and regulators, resulting in substantial financial costs.

2. Increased Expenses

  • Data breaches stemming from non-compliance can lead to higher costs, including larger financial penalties, regulatory penalties, and costly recovery efforts due to customer data exposure.

3. Ongoing Compliance Requirements

  • Ensuring compliance with PCI standards is an ongoing effort. Merchants must:
    • Maintain compliance at all times
    • Report compliance status annually. Stay updated as PCI DSS standards evolve every three years.

For larger merchants, it may be necessary to engage Qualified Security Assessors (QSAs) or employ Internal Security Assessors (ISAs) to validate compliance.

By partnering with a PCI-compliant provider like Worldline, merchants can mitigate much of the complexity and risk associated with achieving and maintaining PCI compliance independently.

1.

Build and maintain a secure network and systems:

  • Firewall protection: Set up strong firewalls to block unwanted internet traffic from your internal network.
  • Custom passwords: Always change default passwords and security settings on your systems to something unique and secure.
2.

Protect Cardholder Data:

  • Secure data transmission: Encrypt any card data you send over the internet to prevent interception by hackers.
  • Data storage security: Keep card data safe by encrypting it when stored.
3.

Maintain a vulnerability management program:

  • Anti-virus software: Regularly update anti-virus programs to protect against malware threats.
  • Secure software: Regularly update your applications to fix vulnerabilities.
4.

Implement strong access controls 

  • Data access control: Limit access to card data only to employees who need it to perform their jobs.
  • User identification: Use unique IDs for everyone accessing your system to maintain accountability.
  • Physical scurity: Keep card data storage areas locked and only accessible to authorized employees.
5.

Regularly monitor and test networks:

  • Track access: Keep logs of who accesses card data and network resources to quickly spot unusual activity.
  • Security testing: Conduct regular vulnerability scans and testing to find and fix issues
6.

Maintain an Information Security Policy:

  • Security guidelines: Create clear policies and train staff to follow required procedures and best practices on data security.
