Payment Card Industry Data Security Standard (PCI DSS)

PCI DSS is a global security standard established in 2004 by major credit card networks to protect payment card data for any organization that stores, processes, or transmits cardholder information. Unlike consumer privacy laws, it prescribes specific technical controls and compliance requirements that scale based on transaction volume and data handling practices.

About this video

PCI DSS, the Payment Card Industry Data Security Standard, was established in 2004 when major credit card networks including Visa, Mastercard, and Discover jointly developed a unified framework to secure payment card data. The standard applies universally to any organization that collects, processes, or stores cardholder information, making it one of the few security frameworks that is genuinely global in scope rather than tied to a specific region or consumer population. Its primary purpose is to protect the integrity of payment card data, serving both the card networks and the consumers whose financial information is at stake. What distinguishes PCI DSS from most privacy and data protection regulations is its technical depth and specificity. While many regulatory frameworks establish general principles around data protection, PCI DSS defines concrete, enforceable controls covering network design, vulnerability management programs, strong access control measures, regular monitoring and testing, third-party penetration testing requirements, and formal information security policies. Organizations must address not just what they protect but how their networks are architected and maintained to meet those protections. Compliance with PCI DSS is structured across multiple levels determined by transaction volume and the nature of an organization's card data handling. Lower-volume merchants may fulfill requirements through self-assessment questionnaires, while large-scale processors and organizations retaining card data long-term are subject to stricter mandates, including independent third-party assessments to validate adherence to the full range of required controls. This tiered approach ensures that compliance obligations are proportionate to the risk and scope of each organization's payment processing environment.

Key terms

Payment Card Industry Data Security Standard
PCI DSS
A set of security requirements mandated by major credit card brands that organizations must follow to process, store, or transmit cardholder data. PCI DSS covers controls such as encryption, access restriction, and regular security testing.
Vulnerability Assessment
The process of identifying, quantifying, and prioritizing vulnerabilities in a system.
Access Control
A security mechanism that restricts access to resources based on policies, roles, or identity.
Penetration Testing
An authorized simulated attack on a system to identify and evaluate security vulnerabilities.
Security Policy
A formal document that defines an organization's security goals, rules, and responsibilities.
Compliance Level
A tiered classification under PCI DSS that determines the specific security requirements and audit obligations an organization must meet based on its volume and type of payment card processing activity.

Transcript

The Payment Card Industry Data Security Standards, or PCI DSS, was put into place to protect credit card data — essentially any company that processes credit cards.

All of the big credit card companies, like Visa, Mastercard, Discover and many more, got together and decided that they needed to protect this credit card processing, and that anybody that stored or processed credit card information needed to have a stricter level of security to protect this data. In essence, it's protecting these credit card companies and also protecting us consumers, to make sure that our credit card information was safe.

The standard was put into place in 2004 and really applies to anybody that's processing credit card information. So if you're collecting any kind of credit card information, or processing it, you must comply with it.

Not a Privacy Regulation

PCI DSS is really not designed around consumer privacy. A lot of laws and regulations are designed to protect the consumer and the privacy of that data that's being collected on that consumer. PCI DSS is much different: it's designed to protect the credit card information, and in its nature it's much more technical in detail.

Where a lot of our privacy laws are designed around general guidelines of what you need to implement to make sure that your network is secure and that data is secure, when it comes to PCI DSS it gets much more technical in detail and lays out all of the steps, all of the controls, that you need to put into place to protect that credit card information. So it gets a lot into your network and how your network is designed, and specific design principles within your network.

Highlights

Here are some highlights around PCI DSS.

  • For one, it's global in nature. A lot of laws and regulations really apply to residents in a certain area; this is global, in which it doesn't matter where you are — it really applies to you if you're processing credit card information.
  • It is more technical in nature, protecting that cardholder's data and the credit card information.
  • It sets up things like maintaining a proper vulnerability management program.
  • It talks about implementing strong access control measures.
  • It talks about regularly monitoring and testing a network, and you have to set up outside sources that do pen testing across your network.
  • It talks about maintaining information security policies within your organization.

Compliance Levels

There's this compliance level with it, and there's different levels, so you have to comply with these different levels based off of what you're doing with the credit card information.

If you're just collecting it, processing it, and it's not at a high volume, then you fall under the basic level, and there might be just some self-evaluations that you go through to comply with PCI DSS. Much bigger companies, though, that are doing things on a much more global level and also saving this information long term, have to comply with a much stricter level of PCI DSS. Some of that may include having a third party come and do an evaluation on your company to make sure that you are complying with the different controls involved and the different standards.
