PCI-DSS

Abstract

The Payment Card Industry Data Security Standard (PCI-DSS) is a vital set of policies and procedures designed to secure credit, debit, and cash card transactions, and to protect cardholders' personal information. It's mandated for all organizations handling major credit card schemes.

Overview

PCI-DSS aims to reduce data breaches and fraud in card transactions. It applies to all entities involved in card processing, including merchants, processors, and others who handle cardholder data (CHD) and sensitive authentication data (SAD).

Key Components

1. Build and Maintain a Secure Network and Systems

   • Firewalls to protect CHD.
   • No vendor-supplied defaults for security parameters.

2. Protect Cardholder Data

   • Secure storage of CHD.
   • Encryption of CHD across open networks.

3. Maintain a Vulnerability Management Program

   • Regular anti-virus updates.
   • Secure systems and applications.

4. Implement Strong Access Control Measures

   • Restricted access to CHD.
   • Authentication for system access.
   • Physical access control to CHD.

5. Regularly Monitor and Test Networks

   • Monitor access to network resources and CHD.
   • Frequent testing of security systems.

6. Maintain an Information Security Policy

   • Policy for information security for all personnel.

Historical Perspective

• Early 2000s: Rising concerns over card data security.
• 2004: Formation of PCI-DSS.
• Ongoing: Updates to address new threats and technologies.

Compliance and Legal Implications

Non-compliance can lead to fines, increased fees, or loss of card processing abilities. Legal issues may arise from breaches of cardholder data.
