PCI DSS is a set of security standards designed to ensure that all companies that accept, process, store, or transmit credit card information maintain a secure environment. It was developed to enhance cardholder data security and facilitate the broad adoption of consistent data security measures globally.
Key Components:
- Build and Maintain a Secure Network and Systems.
- Protect Cardholder Data.
- Maintain a Vulnerability Management Program.
- Implement Strong Access Control Measures.
- Regularly Monitor and Test Networks.
- Maintain an Information Security Policy.
Compliance Levels
PCI DSS compliance is divided into four levels based on the number of transactions a business processes annually:
- Level 1 : Over 6 million card transactions per year.
- Level 2 : Between 1 million and 6 million card transactions per year.
- Level 3 : Between 20,000 and 1 million card transactions per year.
- Level 4 : Fewer than 20,000 card transactions per year.
Compliance Validation:
- Self-Assessment Questionnaire (SAQ) : A validation tool for merchants and service providers to assess their PCI DSS compliance.
- Qualified Security Assessor (QSA) : An external assessor who performs the on-site assessment for Level 1 merchants.
- Internal Security Assessor (ISA) : An internal employee who has the necessary training and certification to assess their organization’s compliance.
Penalties For Non-Compliance
Non-compliance with the Payment Card Industry Data Security Standard (PCI DSS) can lead to severe penalties and consequences, which vary depending on the nature and extent of the non-compliance. Here are some of the potential penalties and repercussions:
Financial Penalties
- Fines : Payment card companies (e.g., Visa, MasterCard) may impose fines ranging from $5,000 to $100,000 per month for non. The exact fine depends on factors such as the size of the organization, the duration of non-compliance, and the severity of the violations.
- Increased Transaction Fees : Non-compliant merchants may face higher transaction fees imposed by their acquiring bank or payment processor.
- Suspension of Credit Card Processing : Businesses may lose the ability to process credit card payments if they fail to comply with PCI DSS requirements. This can lead to significant revenue loss and operational disruptions.
