PCI DSS

PCI DSS Compliance: Requirements, Consequences & GRC Software Assistance

PCI security standards are technical and operational requirements set by the PCI Security Standards Council (PCI SSC) to protect cardholder data.

Non-compliance with PCI DSS can result in fines, legal action, reputational damage, and loss of customer trust. How can Risk Cognizance help with PCI DSS.

PCI DSS: Payment Card Industry Data Security Standard

The Payment Card Industry Data Security Standard (PCI DSS) is a globally recognized set of security standards designed to ensure that all organizations that accept, process, store, or transmit credit card information maintain a secure environment. Established by the major payment card brands (Visa, Mastercard, American Express, Discover, JCB) through the PCI Security Standards Council (PCI SSC), PCI DSS aims to reduce credit card fraud and protect sensitive cardholder data.

With the full enforcement of PCI DSS v4.0 requirements as of March 31, 2025, the standard has evolved to address the latest threats and technologies, shifting towards a focus on continuous security and a more proactive approach to risk management.

Who Does PCI DSS Apply To?

PCI DSS compliance is mandatory for any entity that processes, stores, or transmits Cardholder Data (CHD) and/or Sensitive Authentication Data (SAD), or whose environment could impact the security of the Cardholder Data Environment (CDE). This includes:

• Merchants: Businesses of all sizes, from small online shops to large retail chains, that accept credit card payments.
• Processors: Companies that process credit card transactions on behalf of merchants.
• Acquirers (Acquiring Banks): Financial institutions that process credit and debit card transactions for merchants.
• Issuers: Financial institutions that issue credit and debit cards to consumers.
• Service Providers: Any third-party entity that handles or could affect cardholder data environments (e.g., hosting providers, payment gateways, managed security service providers, cloud providers).

Organizations are typically classified into four compliance levels based on their annual transaction volume, which dictates the specific validation requirements (e.g., requiring a Qualified Security Assessor (QSA) audit versus a Self-Assessment Questionnaire (SAQ)).

The 12 Core Requirements of PCI DSS v4.0

PCI DSS v4.0 is structured around six overarching goals, translated into 12 core requirements, each with numerous sub-requirements:

• Goal 1: Build and Maintain a Secure Network and Systems
• Requirement 1: Install and maintain network security controls (e.g., firewalls).
• Requirement 2: Apply secure configurations to all system components.
• Goal 2: Protect Account Data 
• Requirement 3: Protect stored account data.  Requirement 4: Protect cardholder data with strong cryptography during transmission over open, public networks.
• Goal 3: Maintain a Vulnerability Management Program 
• Requirement 5: Protect all systems and networks from malicious software. 
• Requirement 6: Develop and maintain secure systems and software (including new client-side security requirements like script inventory and integrity checks).
• Goal 4: Implement Strong Access Control Measures 
• Requirement 7: Restrict access to cardholder data by business need-to-know. 
• Requirement 8: Identify users and authenticate access to system components (expanded MFA requirements for all CDE access). 
• Requirement 9: Restrict physical access to cardholder data.
• Goal 5: Regularly Monitor and Test Networks
• Requirement 10: Log and monitor all access to system components and cardholder data.
• Requirement 11: Test security of systems and networks regularly (e.g., quarterly vulnerability scans, annual penetration tests, change detection).
• Goal 6: Maintain an Information Security Policy
• Requirement 12: Support information security with organizational policies and programs (includes enhanced security awareness training and improved third-party risk management).

PCI DSS v4.0 also introduces new "customized approach" validation options, allowing for more flexible ways to meet security objectives, provided detailed documentation and testing are performed and reviewed by QSAs.

The PCI DSS Compliance Process

Achieving and maintaining PCI DSS compliance is an ongoing process, typically involving:

Scoping: Accurately identifying the Cardholder Data Environment (CDE) and all systems, networks, and processes that store, process, or transmit cardholder data, or could impact the security of the CDE.

Assessment: Conducting a thorough assessment against all applicable PCI DSS requirements. This may involve a Self-Assessment Questionnaire (SAQ) for lower-level merchants or a formal audit by a QSA for higher-level merchants and service providers.

Remediation: Addressing any identified gaps or deficiencies to meet all requirements.

Reporting: Submitting the necessary documentation (e.g., Attestation of Compliance (AOC), Report on Compliance (ROC), SAQ) to acquiring banks or payment brands.

Continuous Monitoring: Maintaining an ongoing security posture by continuously monitoring controls, conducting regular scans and penetration tests, and ensuring that security practices evolve with new threats and technologies.

Consequences of Non-Compliance

Failure to comply with PCI DSS can lead to severe consequences, both financial and reputational:

• Hefty Fines: Payment card brands and acquiring banks can impose substantial monthly fines, ranging from $5,000 to $100,000 or more per month, depending on the level of non-compliance and transaction volume. These fines are often passed down to the merchant or service provider.
• Increased Transaction Fees: Acquiring banks may increase transaction fees for non-compliant entities.
• Payment Processing Suspension: The inability to process credit card payments, which can cripple a business reliant on card transactions.
• Data Breaches: Non-compliance significantly increases the risk of a data breach, which can lead to:
• Forensic Investigation Costs: Expenses for investigating the breach.
• Legal Fees and Lawsuits: Potential class-action lawsuits from affected customers and legal defense costs.
• Brand Damage & Loss of Trust: Severe reputational harm, leading to customer churn and loss of business opportunities that can take years to recover.
• Government Penalties: Additional fines or audits from regulatory bodies if personal data is compromised.
• MATCH List/TMF: Non-compliant merchants might be placed on the Merchant Alert to Control High-Risk Merchants (MATCH) list (also known as the Terminated Merchant File or TMF), effectively banning them from processing payments through most major providers.
