Overview#
Payment Card Industry Data Security Standard (PCI DSS) is a proprietary information security standard for organizations that handle branded Payment Cards from the Payment Card Industry members.Payment Card Industry Data Security Standard is mandated by the card brands and administered by the Payment Card Industry Security Standards Council.
Payment Card Industry Data Security Standard was created to increase controls around Cardholder Data to reduce credit card fraud.
Validation of compliance is performed periodically, either by an external Qualified Security Assessor (QSA) that creates a Report on Compliance (ROC) for organizations handling large volumes of transactions, or by Self-Assessment Questionnaire (SAQ) for companies handling smaller volumes.
PCI DSS 4.0 #
The 12 core (PCI DSS) requirements did not fundamentally changed and they remain the critical foundation for securing payment card data. However, the requirements have been redesigned to focus on security objectives to guide how security controls should be implemented.PCI DSS 4.0 aligns with the NIST.SP.800-63B for authentication and life cycle management. As the payments industry has gradually moved to the cloud, stronger authentication standards to payment and control access logins are necessary. '=
PCI DSS 4.0 considers:
- Multi-Factor Authentication (MFA) usage for all accounts that have access to the Cardholder Data, not just administrators accessing the cardholder data environment.
- Passwords for accounts used by applications and systems must be changed at least every 12 months and upon suspicion of compromise.
- Use of strong passwords for accounts used by applications and systems, which must contain at least 15 characters, including numeric and alphabetic characters. PCI DSS requires that the prospective passwords be compared against the list of known bad passwords.
- Access privileges must be reviewed at least once every six months.
- Vendor or Third-party accounts may be enabled only as needed and monitored when in use.
The PCI DSS 4.0 standard is built with a Zero Trust mindset, permitting organizations to build their own unique, pluggable authentication solutions to meet the data security regulatory requirements. At the same time, authentication methods can scale to fit the company’s transaction objectives and risk environment.
Finally, PCI SSC has partnered with Europay, MasterCard, and VISA to implement the use of the 3DS Core Security Standard during transaction authorization.
Payment Card Industry Data Security Standard Requirements#
Payment Card Industry Data Security Standard specifies twelve requirements for compliance, organized into six logically related groups called "control objectives".Each version of Payment Card Industry Data Security Standard has divided these twelve requirements into a number of sub-requirements differently, but the twelve high-level requirements have not changed since the inception of the standard.
Control objectives PCI DSS requirements#
Build and Maintain a Secure Network and Systems#
- 1. Install and maintain a firewall configuration to protect cardholder data
- 2. Do NOT use vendor-supplied defaults for system passwords and other security parameters Protect Cardholder Data
- 3. Protect stored Cardholder Data
- 4. Encrypt transmission of Cardholder Data across open, public networks
Maintain a Vulnerability Management Program#
- 5. Protect all systems against malware and regularly update antivirus software or programs
- 6. Develop and maintain secure systems and applications
Implement Strong Access Control Measures#
- 7. Restrict access to Cardholder Data by business need to know
- 8. Identify and Authenticate access to system components
- 9. Restrict physical access to Cardholder Data
Regularly Monitor and Test Networks#
- 10. Track and monitor all access to network resources and Cardholder Data
- 11. Regularly test security systems and processes
Maintain an Information security Policy#
- 12. Maintain a policy that addresses information security for all personnel
Many Versions#
- PCI Data Security Standard v3.1 - Jan 2015
- PCI Data Security Standard v3.2 - Apr 2016
- PCI Data Security Standard v3.2.1 - Apr 2018
"Secure Version of TLS"#
"Secure Version of TLS" is used in several of their documents which has been clarified "as defined by NIST.SP.800-52"Multi-Factor Authentication[2]#
Payment Card Industry Data Security Standard requirement 8.3, requires the use of Multi-Factor Authentication for all remote network access that originates from outside the network to a Cardholder Data Environment (CDE).Beginning with PCI-DSS version 3.2, the use of Multi-Factor Authentication is also required for all administrative access to the Card Data Environment (CDE), even if the user is within a trusted network.
Some clarification on Payment Card Industry Data Security Standard and Multi-Factor Authentication
Troy Leach, Payment Card Industry Data Security Standard's Chief Technology Officer clarifies this further by stating,[3]
[A] significant change in PCI DSS 3.2 adds multi-factor authentication as a requirement for any personnel with administrative access into the cardholder data environment, so that a password alone is not enough to verify the user’s identity and grant access to sensitive information, even if they are within a trusted network… The most important point is that the change to the requirement is intended for all administrative access into the cardholder data environment, even from within a company’s own network. This applies to any administrator, whether it be a third party or internal, that has the ability to change systems and other credentials within that network to potentially compromise the security of the environment.
