The 12 PCI DSS Requirements
This exclusive video series, PCI Demystified, was developed to assist your organization in understanding what Payment Card Industry Data Security Standard (PCI DSS) is, who it applies to, what the specific requirements are, and what your organization needs to do to become compliant.
The 12 PCI DSS Requirements
The PCI DSS was jointly developed by the payment card brands to encourage and enhance cardholder data security and facilitate the broad adoption of consistent data security measures globally. Its purpose is to ensure that all of the data that lives within the Cardholder Data Environment (CDE) is protected and secured from theft or unauthorized use. If you are a merchant, service provider, or subservice provider who stores, processes, or transmits cardholder data, you are subject to comply with the PCI DSS. The current version, PCI DSS 3.2, has approximately 394 controls, 6 control objectives, and 12 major subject areas. The 12 requirements are:
PCI Requirement 1
“Install and maintain a firewall configuration to protect cardholder data.” Your organization should focus on securing and hardening your network and securing the inbound and outbound traffic.
Learn More about PCI Requirement 1
PCI Requirement 2
“Do not use vendor-supplied passwords and other security parameters.” Most organizations tend to focus on hardening their operating systems, but this requirement is intended for all assets within the environment.
Learn More about PCI Requirement 2
PCI Requirement 3
“Protect stored cardholder data.” This requirement focuses on securing cardholder data at rest; this is the encryption and the storage of sensitive information.
Learn More about PCI Requirement 3
PCI Requirement 4
“Encrypt transmission of cardholder data across open, public networks.” If you transmit cardholder data over open or public networks, that data must be securely and appropriately protected.

PCI Requirement 5
“Protect all systems against malware and regularly update anti-virus software or programs.” Do not focus on only anti-malware or only anti-virus; this requirement deals with both.
Learn More about PCI Requirement 5
PCI Requirement 6
“Develop and maintain secure systems and applications.” There’s more to this requirement than just securing applications. It’s about identifying vulnerabilities, patching your systems, change management, change controls, and secure software development.
Learn More about PCI Requirement 6
PCI Requirement 7
“Restrict access to cardholder data by business need-to-know.” Requirement 7 goes hand-in-hand with Requirement 8; it focuses on authorization.
Learn More about PCI Requirement 7
PCI Requirement 8
“Identify and authenticate access to system components.” Requirement 8 focuses on authentication.
Learn More about PCI Requirement 8
PCI Requirement 9
“Restrict physical access to cardholder data.” If a hacker as physical access to your assets, they pretty much own that data.
Learn More about PCI Requirement 9
PCI Requirement 10
“Track and monitor all access to network resources and cardholder data.” This requirement is all about logging.
Learn More about PCI Requirement 10
PCI Requirement 11
“Regularly test security systems and processes.” Your organization must ensure that you’re testing for vulnerabilities and managing the security of your environment so that your assets are protected.
Learn More about PCI Requirement 11
PCI Requirement 12
“Maintain a policy that address information security for all personnel.” This is the requirement that addresses the policy and procedure management and vendor management of your organization.

Most organizations tend to focus on the 12 requirements, however, we believe there are 2 appendices that might as well be requirements. The first is for shared hosted services providers and the second is for Designated Entities. We’ll discuss these appendices further in a later video
The 12 PCI DSS Requirements
The PCI DSS is comprised of 12 requirements and 2 appendices that we need to have a discussion about. We start out with Requirement 1, which is focused on securing and hardening the network and the inbound and outbound traffic. Requirement 2 is primarily focused with looking to harden the systems and the applications; most organization really just tend to focus on hardening their operating systems, but Requirement 2 is really intended for all assets within the environment. Requirement 3 is focused on securing cardholder data at rest. This is the encryption and the prohibition of storage of sensitive information. Requirement 4 is focused on making sure that when you transmit cardholder data over open or public networks, that the data itself is appropriately protected. Requirement 5 deals with antimalware and deals with antivirus.
Requirement 6 has actually got quite a bit that it deals with. This requirement, when we talk about the PCI DSS, talks about securing applications, but there’s a little bit more than that. It’s identifying vulnerabilities, it’s patching your system, it’s change management, it’s change controls, it’s secure software development and all the requirements that go along with making sure the applications are maintained securely. Requirement 7 and Requirement 8 kind-of go hand-in-hand; Requirement 7 is authorization and Requirement 8 is authentication. We change things up a little bit when we get to Requirement 9. Requirement 9 is focused on the physical security of the environment. If I’m a hacker and I have physical access to your assets, I can pretty much own the data on it. We get to Requirement 10, which is all of your logging. When we get to Requirement 11, it’s focused on making sure that all of things that you’ve put in place to secure your assets are functioning appropriately. This is where we’re testing for vulnerabilities and making sure we’re managing the security of the environment. Requirement 12 is the policy and procedure management and vendor management of the organization. This is really the management aspect of the PCI DSS itself.
Most organizations, most people tend to focus on the 12 requirements themselves, however there are 2 additional appendices that might as well be requirements. The first one we have is for shared hosted services providers. If you have a question of whether you’re a shared hosted service provider, please look at Requirement 2.6 in the PCI DSS. That will clearly explain what a shared hosted service provider is and talk about what the requirements are there. Lastly, we have the last appendix which we need to be concerned with or have conversations about. This is the Designated Entities Appendix. Once again, we’ll talk about what that is when we get to that requirement.
