What is PCI DSS?
PCI DSS stands for Payment Card Industry Data Security Standard. It is a set of security best practices developed to ensure the secure handling of credit and payment card data. PCI DSS was created by major credit card companies, including Visa, MasterCard, and American Express, to protect cardholders’ sensitive financial information and to reduce the risks of a data breachWhat is a Data Breach? A data breach is a security incident in which unauthorized individuals access sensitive, confidential, or protected information. These breaches can occur through various means, including… More and fraud. As the standard evolved, other credit card companies joined in the development of the Standard.
What are the key requirements of PCI DSS?
PCI DSS consists of several key requirements and security controls that organizations must implement to protect credit card data and achieve regulatory complianceWhat is Regulatory Compliance? Regulatory compliance refers to the act of adhering to the laws, directives, and requirements set forth by governmental bodies and industry authorities that pertain to a… More. The standard is organized into six primary goals, each with specific requirements. There are six main headings in The Standard. Each heading contains subsections that specify in detail the evidentiary expectations. There are a total of twelve subsections across the entire Standard.
Build and Maintain a Secure Network and Systems
- Install and Maintain Network Security Controls.
- Apply Secure Configurations to All System Components.

What are the consequences of PCI DSS non-compliance?
The penalties for PCI DSS non-compliance can vary depending on the specific circumstances and the payment card brands involved. While the PCI Security Standards Council itself does not impose penalties, non-compliance consequences typically come from the payment card companies, and acquiring banks. Here are some common penalties and consequences for PCI DSS non-compliance:
- Fines and Penalties: Payment card brands and acquiring banks may impose fines and penalties on organizations that fail to comply with PCI DSS requirements. These fines can vary widely and are often determined based on factors like the severity of the non-compliance and the number of cardholder records compromised in a data breach.
- Increased Transaction Fees: Non-compliant organizations may be subject to higher transaction fees or processing rates due to not meeting PCI DSS requirements.
- Loss of Payment Card Processing Privileges: Acquiring banks may terminate or suspend an organization’s ability to process payment card transactions if they consistently fail to meet PCI DSS compliance standards.
- Legal Action and Lawsuits: In the event of a data breach, organizations that are not PCI DSS compliant may face legal action, including lawsuits from affected individuals or financial institutions seeking damages.
- Remediation Costs: Correcting non-compliance issues and addressing data breaches can be costly, including expenses related to investigation, notification, and remediation.
- Mandated Security Improvements: Organizations that fail to meet PCI DSS compliance may be required to invest in security improvements to align their systems and practices with the standard.
It’s important to note that the specific consequences of PCI DSS non-compliance can vary based on the payment card brands involved and the severity of the non-compliance. Organizations are strongly encouraged to take PCI DSS compliance seriously and make ongoing efforts to meet the requirements to avoid non-compliance’s potential consequences. Additionally, protecting account data extends beyond compliance; it is essential for maintaining trust and security in the payment card industry.
The future of PCI DSS
The future of PCI DSS will likely involve:
- Zero Trust: Strict, recurring identity verification for access network resources.
- Cloud SecurityWhat is Cloud Security? Cloud security refers to the measures and strategies used to protect data, applications, and resources stored, accessed, and processed in cloud computing environments. It involves a… More: More guidance for securing payment card data in the cloud.
- Continuous Compliance: A shift toward ongoing compliance and monitoring.
- Global Adoption: Greater alignment with international data security standards.
- Emerging Technologies: Adapting to new tech like AI, blockchain, and quantum computingWhat is Quantum Computing? Quantum computing is a cutting-edge field that leverages the principles of modern physics to perform operations significantly faster than classical computers. Classical computers, including the laptops,… More.
