The PCI 3DS Core Security Standard is organized into two parts. Part 1 is a baseline of technical and operational security controls that are designed to protect the 3DE.

  • Maintain security policies for all personnel
  • Secure network connectivity
  • Develop and maintain secure systems
  • Vulnerability management
  • Manage access
  • Physical security
  • Incident response preparedness

Part 2 of the requirements are the 3DS Security Requirements that are designed to protect 3DS data and processes. Regardless of an entity's PCI DSS compliance, if the entity is performing 3DS functions then the following Part 2 requirements must be evaluated as part of the assessment.

  • Validate scope
  • Security governance
  • Protect 3DS systems and applications
  • Secure logical access to 3DS systems
  • Protect 3DS data
  • Cryptography and key management
  • Physically secure 3DS systems

Why our services are important to you
The PCI 3DS Core security requirements are designed to protect the 3DS environments where specific 3DS functions are performed or 3DS data is stored. The specific functions to be protected include: the 3DS server, the 3DS Directory Server, and the 3DS Access Control Server.

The EMV (stands for “Europay, MasterCard, and Visa”) 3-D Secure Protocol and Core Functions Specification, which defines how to implement the 3-D Secure Protocol, is managed and maintained by EMVCo. The PCI 3DS Core Security Standard that supports 3DS implementations is managed and maintained by the PCI Security Standards Council.

3DS (EMV Three Domain Secure, EMV 3-D Secure or EMV 3DS) is a protocol designed to enable secure authentication for card-not-present (CNP) e-commerce purchases. The three domains consist of the following: Issuer Domain, Merchant/Acquirer Domain, Interoperability Domain (e.g. payment system).

Compared to version 1 of the 3DS protocol, new features in 3DS (version 2.0) include added support for application-based authentication as well as integration with digital or mobile wallets. There is also support for more authentication channels to help merchants further validate transactions within these complex card-not-present environments. The supported Cardholder Verification Methods (CVM) include Online PIN, Offline PIN, Challenge-response, Shared Secret, Static Password, Biometric, One-time Passcode, and the supported Consumer Device Information (CDI) could be Smartphone, Laptop or Tablet.

PCI 3DS standard compliance can be the mandatory requirement defined by the card brands or your cooperative entities when the functions related to the new version of 3DS are implemented. atsec has plenty of experience and knowledge in different security areas related to PCI 3DS standard and can help you to improve the overall security level of the 3DS environment.
