Data security is a top priority for Discover. The Discover Information Security & Compliance (DISC) program was developed to implement and maintain efficient data security requirements and procedures for its constituents and promote the adoption of secure transaction processing of cardholder data on the Discover network.
As part of this ongoing initiative, Discover partnered with other major payment card brands to form the Payment Card Industry Security Standards Council, LLC ("PCI SSC"). The PCI SSC was launched on September 7, 2006 to manage the ongoing evolution of the Payment Card Industry ("PCI") security standards, which focus on improving payment account security throughout the transaction process. Discover is firmly committed to the PCI security standards as the industry data protection standards for the payment card industry. The DISC program is designed to promote compliance to the requirements of the PCI security standards by helping you safeguard cardholder data and limit data compromises.
Data Security is a top priority for Discover. To that end, Discover is committed to supporting the Payment Card Industry Data Security Standard (“PCI DSS”) as the security requirement for entities that process, store or transmit cardholder data on the Discover network. As a service provider to Discover Merchants, we require that your organization complies with the PCI Data Security Standard at all times.
All service providers that process, store or transmit cardholder data on the Discover network are required to report their compliance status to Discover Network on an annual basis. In order to validate and report their compliance status to Discover Network, service providers must complete and submit one of the following:
On-site assessment
Service providers that completed an on-site assessment using PCI DSS v1.2 are required to submit Appendix E of the PCI DSS Requirements and Security Assessment Procedures v1.2: Attestation of Compliance - Service Providers, as well as the Executive Summary of the Report on Compliance (ROC).
Note: Discover requires service providers that are not fully compliant with the PCI DSS to also complete the "Action Plan for Non-Compliant Status" section of the Attestation of Compliance.1
Self-Assessment
Service Providers that completed an on-site assessment using PCI DSS v1.1 are required to submit the Executive Summary from their Report on Compliance (ROC). Please note: all assessments that commence after January 1, 2009 must use PCI DSS v1.2.
Service providers that perform a self-assessment are required to complete PCI DSS Self-Assessment Questionnaire D and submit the Service Provider Version of the Attestation of Compliance. Note: Discover requires service providers that are not fully compliant with the PCI DSS to also complete the "Action Plan for Non-Compliant Status" Section of the Attestation of Compliance.1

*Example: Service providers must submit their 2009 compliance status by December 31, 2009. The report must have been completed for the calendar year of 2009.

Data Security Compliance Requirements
In order to help protect the integrity of cardholder data, Discover requires ALL merchants that process, store or transmit cardholder data on the Discover network to comply with the Payment Card Industry Data Security Standard (“PCI DSS”) at all times. In addition, merchants may also be required to validate and report their compliance directly to Discover Network or to their acquirer.
All merchants that process Discover Cardholder data are required to comply with the PCI DSS at all times. Prior to beginning the compliance assessment process, it is important for merchants to understand how they are defined under the DISC program. The information below will help merchants identify what Merchant Level they fall under and the compliance validation and reporting requirements that correspond to that merchant level. Lastly, it is important to understand whether you have a contractual relationship with Discover (“Discover Merchants”) or if you have a contract with a Discover Acquirer (“Acquired Merchants”). This factor will help you understand where and how you are required to submit your compliance report.
Step 1: Compliance Requirements
All merchants must comply with the Payment Card Industry Data Security Standard. Discover requires all NEW compliance assessments that commence on or after January 1, 2009 to be performed using PCI DSS v1.2. If you started your compliance assessment prior to January 1, 2009 using PCI DSS v1.1, you may continue your assessment using that version of the standard. The calendar below provides an overview of which standards may be used over the next two years.
