What is PCI Compliance
What is PCI Compliance?
PCI DSS stands for Payment Card Industry Data Security Standard. It is a global security standard created by major card brands (Visa, Mastercard, American Express, Discover, JCB) and managed by the PCI Security Standards Council. If your business accepts credit or debit cards, you are contractually required to comply with PCI DSS.
Why PCI Compliance Matters
PCI DSS helps prevent data breaches and financial fraud by requiring businesses to secure cardholder data. Non-compliance can lead to fines, increased transaction fees, and even loss of card processing privileges.
PCI DSS v4.0.1 – What’s New?
The latest version, PCI DSS v4.0.1, became effective in June 2024. It clarifies requirements introduced in v4.0 and enforces all future-dated controls by March 31, 2025. Key changes include:
- MFA Everywhere: Multi-factor authentication required for all access to the Cardholder Data Environment (CDE).
- Client-Side Script Management: Merchants must inventory and monitor scripts on payment pages.
- Targeted Risk Analysis: Documented risk reviews for malware, access, and patching.
- Annual Scope Review: Mandatory after major changes.
How Do You Comply?
Compliance depends on your transaction volume:
- Small merchants: Complete a Self-Assessment Questionnaire (SAQ) and quarterly scans.
- Large merchants/service providers: Undergo an on-site assessment by a Qualified Security Assessor (QSA).
