What is PCI Compliance?

Posted 25th Feb 2024 by Travis Swientek

PCI Compliance ensures organizations protect cardholder data by following the PCI Data Security Standard (PCI DSS), set by the PCI Security Standards Council, to prevent credit card fraud and data breaches.

PCI compliance embodies the commitment of organizations to protect cardholder data by adhering to the Payment Card Industry Data Security Standard (PCI DSS). Established by the PCI Security Standards Council (PCI SSC), these standards are designed to secure credit card and debit card e-commerce transactions against credit card data theft and fraud.

The history of PCI-DSS began in 2004, in response to an increase in payment fraud. Founding members included credit card brands American Express, Discover Financial Services, JCB International, Mastercard, and Visa, which convened to set a common set of security standards and introduced PCI DSS 1.0 in December 2004. Today, every merchant that accepts credit card payments must be PCI compliant. PCI DSS includes adherence to security requirements, policies, procedures, network architecture, software design, and other measures. Failure to meet compliance requirements can leave businesses vulnerable to the damaging effects of data breaches, which includes fines, remediation costs, and lost customer trust.

Qualified Security Assessor (QSA) companies are independent security organizations that have been qualified by the PCI Security Standards Council that validate that an organization is PCI DSS compliant. Companies can use a Self-Assessment Questionnaire (SAQ), a validation tool designed to help merchants and service providers evaluate and generate a report on compliance with PCI requirements.

Elements of PCI Compliance

  • Building and Maintaining a Secure Network: Implementing firewalls and secure network configurations to protect sensitive data, and changing default passwords to secure systems against unauthorized access to credit card information.
  • Protection of Cardholder Data: Encrypting transmission of cardholder data across public networks and ensuring that both credit card transactions and storage of such data is secure and minimized.
  • Vulnerability Management: Regularly updating anti-virus software, developing and maintaining secure systems and applications to protect against malware, hackers, and other security threats.
  • Strong Access Control Measures: Restricting access to cardholder data to only those individuals whose job requires such access, thereby enforcing the principle of least privilege.
  • Regular Monitoring and Testing: Monitoring all access to network resources and cardholder data, and regularly testing security systems and processes to identify and rectify vulnerabilities in order to protect against data breach. An approved scanning vendor (ASV) is an organization with a set of security services and tools to conduct external vulnerability scanning services to validate adherence with PCI DSS Requirement 11.2. Companies with vulnerability scanning infrastructure can submit an attestation of compliance to an ASV in order to meet the scan validation requirement.
  • Information Security Policy: Establishing a robust information security policy that all employees must follow, ensuring that the policy is disseminated throughout the organization.

Challenges in Achieving PCI Compliance

Organizations face several challenges in achieving PCI compliance, including the complexity of the requirements, the continuous evolution of cybersecurity threats, and the need for ongoing adherence to compliance standards.

Teleport's Take

Teleport Access Platform supports PCI compliance efforts by providing secure infrastructure access with functionality that adheres to the core requirements of PCI DSS.

  • Automated Access Controls: Teleport automates the enforcement of access controls, ensuring that only authorized personnel have access to cardholder data, thus supporting strong access control measures.
  • Encryption and Data Protection: Teleport facilitates the secure transmission of cardholder data across public networks by employing robust encryption, thereby protecting sensitive information during transit.
  • Audit Trails and Real-Time Monitoring: With comprehensive logging and real-time monitoring capabilities, Teleport offers visibility into access and activities involving cardholder data, aiding in the regular monitoring and testing of security controls.
  • Compliance Reporting and Risk Assessment: Teleport simplifies compliance reporting and risk assessment processes, providing detailed evidence of compliance with PCI DSS requirements and helping organizations identify and mitigate potential security vulnerabilities.

By integrating Teleport into their security and compliance frameworks, organizations can strengthen their PCI DSS compliance posture. Teleport's focus on secure access management, encryption, and continuous monitoring supports the protection of cardholder data against emerging threats, ensuring that organizations can maintain the trust of their customers and avoid the consequences of non-compliance, including fines and reputational damage.
