The Payment Card Industry Data Security Standard (PCI DSS) is a set of security standards established by major credit card companies to protect sensitive cardholder data and ensure secure payment card transactions. Achieving PCI DSS compliance is essential for the best cybersecurity in organizations that handle credit card information to build trust with customers, prevent data breaches, and avoid potential legal and financial penalties. In this article, we will discuss five crucial steps toward achieving PCI DSS compliance.
Understand PCI DSS Requirements
The first step toward achieving PCI DSS compliance is to thoroughly understand the standard's requirements. PCI DSS consists of 12 key requirements, each containing various sub-requirements. These requirements cover areas such as network security, access control, regular monitoring, and incident response. It is important to carefully study and comprehend each requirement to ensure compliance.
According to Verizon's 2021 Payment Security Report, only 27.9% of organizations were fully compliant with PCI DSS during their initial assessment. A study by Verizon also found that organizations that experienced a data breach were 50% less likely to be compliant with PCI DSS requirements compared to organizations that did not suffer a breach.

Identify Cardholder Data and Scope
According to the Verizon Data Breach Investigations Report (DBIR) 2021, 85% of breaches involve a human element, such as social engineering or errors made by employees. Clearly defining the scope helps organizations focus their efforts on protecting the most critical areas.
To effectively implement PCI DSS compliance measures, organizations must identify and protect confidential data for the cardholder data they handle and determine the scope of their compliance efforts. This involves conducting a comprehensive inventory of systems, processes, and people that interact with cardholder data. By clearly defining the scope, organizations can focus their compliance efforts on the relevant areas, reducing the complexity and cost of the compliance process.
The 2021 Cost of a Data Breach Report by IBM Security and Ponemon Institute revealed that the average cost of a data breach in 2020 was $3.86 million, with a mean time to identify and contain a breach of 280 days.
Implement Security Controls
The 2021 Global Encryption Trends Study by the Ponemon Institute reported that 54% of organizations surveyed had experienced a data breach involving sensitive data in the past 12 months. Encryption is a critical security control for protecting cardholder data.
Once the scope is defined, organizations need to implement the necessary security controls to protect cardholder data. This step involves addressing each requirement of the PCI DSS standard through the deployment of appropriate technical and operational measures. Examples of security controls include firewalls, encryption, access controls, network segmentation, intrusion detection systems, and regular security patching. Organizations should select and implement controls that are appropriate for their specific environment.
A study by Trustwave found that 37% of security breaches in 2020 were related to vulnerabilities in web applications, emphasizing the importance of implementing secure coding practices and regular security patching.
Regularly Monitor and Test Security Measures
The 2021 DBIR by Verizon revealed that 61% of data breaches involved the use of stolen or compromised credentials. Regular monitoring can help detect unauthorized access attempts and prevent potential breaches.
PCI DSS compliance is an ongoing process that requires continuous monitoring and testing of security measures. Regular monitoring helps identify potential vulnerabilities, suspicious activities, and unauthorized access attempts. It involves activities such as reviewing logs, analyzing system alerts, and conducting periodic vulnerability scans and penetration tests. By consistently monitoring and testing security measures, organizations can promptly address any weaknesses or vulnerabilities, thereby strengthening their overall security posture.
According to the 2020 Cost of Cybercrime Study by Accenture, the average cost of cybercrime for organizations increased by 13% in 2020, reaching $13 million. Regular monitoring and testing help organizations identify and mitigate security vulnerabilities before they can be exploited.
Maintain and Review Compliance
A survey by SecurityMetrics found that only 27% of organizations maintained full PCI DSS compliance a year after achieving it. Regular maintenance and review processes are crucial for ensuring continued adherence to the standard's requirements.
Achieving PCI DSS compliance is not a one-time effort but an ongoing commitment in your IT security strategy. Organizations must maintain and review their compliance status regularly to ensure continued adherence to the standard's requirements. This involves conducting annual PCI DSS assessments, self-assessments, and vulnerability scans. Additionally, organizations should document policies and procedures, train employees on security awareness, and regularly review and update security controls to address evolving threats and industry changes.
The 2020 Cost of Compliance Report by Ponemon Institute stated that non-compliant organizations faced an average of $14.82 million in annualized cost of compliance, which is almost double the average cost for compliant organizations.
Achieving PCI DSS compliance is crucial for organizations that handle payment card information. By following these five steps, organizations can establish a robust security framework to protect sensitive cardholder data, prevent data breaches, and build trust with their customers. While achieving compliance requires effort and investment, the benefits of enhanced security, reduced risk, and maintaining a positive reputation outweigh the costs. Adhering to the PCI DSS standard not only protects an organization's assets but also contributes to the overall security and integrity of the payment card industry.
