"Cybersecurity is not just a matter of compliance; it's a commitment to safeguarding the trust and security of our customers' financial information".
The Payment Card Industry Data Security Standard (PCI DSS) is a set of security standards and requirements established to ensure the secure processing, storage, and transmission of payment card data. It was developed by the Payment Card Industry Security Standards Council (PCI SSC), an organization founded by major credit card companies like Visa and MasterCard in 2004.
PCI DSS serves as a comprehensive framework for organizations that handle payment card data, including merchants, payment processors, financial institutions, and service providers. Its primary goal is to protect the confidentiality and security of cardholder data, prevent data breaches, and reduce credit card fraud.
Achieving compliance with PCI DSS involves a combination of technical and procedural measures. Organizations that process or handle payment card data must undergo regular security assessments, including self-assessments and on-site audits conducted by Qualified Security Assessors (QSAs). Compliance is typically validated on an annual basis.
Build and Maintain a Secure Network and Systems:
- Install and maintain a firewall configuration to protect cardholder data.
- Do not use vendor-supplied default passwords and other security parameters.
Protect Cardholder Data:
- Protect stored cardholder data.
- Encrypt transmission of cardholder data across open, public networks.
Maintain a Vulnerability Management Program:
- Use and regularly update anti-virus software or programs.
- Develop and maintain secure systems and applications.
Implement Strong Access Control Measures:
- Restrict access to cardholder data by business need-to-know.
- Assign a unique ID to each person with computer access.
- Restrict physical access to cardholder data.
Regularly Monitor and Test Networks:
- Track and monitor all access to network resources and cardholder data.
- Regularly test security systems and processes.
Maintain an Information Security Policy:
- Maintain a policy that addresses information security for all personnel.
Failure to comply with PCI DSS can result in penalties, fines, and restrictions on processing payment card transactions. Compliance not only helps protect sensitive cardholder data but also enhances an organization’s reputation and trustworthiness among customers and partners in the payment card industry.
