What is PCI DSS, in plain English?
PCI DSS (Payment Card Industry Data Security Standard) is a set of requirements created by major card brands to protect cardholder data. It applies to any business — large or small — that accepts, transmits, or stores payment card information. The standard focuses on people, processes, and technology and includes requirements such as encrypting card data, maintaining firewalls, and performing vulnerability scans.

Quick PCI compliance checklist for Connecticut businesses
Use this as an operational checklist — adapt to the size of your business and the way you handle payments.
- Determine your merchant level and validation type. (Levels and validation requirements vary based on transaction volume and how you process payments.) PCI Security Standards Council
- Use a PCI-compliant payment processor / gateway. If possible, avoid storing card data on your own systems — use tokenization and PCI-validated third-party services. PCI Security Standards Council
- Segment and minimize data storage. If you must store data, only keep what’s necessary and encrypt it at rest and in transit.
- Implement strong access control and MFA. Limit who can access systems that touch cardholder data and require multi-factor authentication for administrative access.
- Install and maintain firewalls & endpoint security. Keep software patched and endpoints protected; run regular vulnerability scans and internal testing.
- Perform quarterly external scans & annual validation. Use an Approved Scanning Vendor (ASV) for required external scans and complete the appropriate SAQ or ROC.
- Train staff and create incident response plan. Employees are the first line of defense. Maintain a breach response plan that includes CT reporting steps (notify residents and the CT Attorney General).
- Document everything. Keep evidence of policies, scans, patching, and risk assessments — documentation is vital for recovery and demonstrating compliance
