PCI DSS

Compliance with PCI physical security requirements is essential for protecting card payment transactions and safeguarding sensitive cardholder data. Organizations that handle cardholder data must implement strong physical security measures to control access to areas where this data is stored, processed, or transmitted. Properly securing physical access helps prevent unauthorized entry and reduces the risk of costly data breaches.

Learn how to meet these requirements and strengthen your organization’s PCI DSS compliance.

PCI DSS network and data flow diagrams play a critical role in visualizing how cardholder data moves into, though, and out of your organization’s systems.

These diagrams not only help you identify where sensitive payment information is stored, processed, or transmitted but also support compliance with PCI DSS requirements. By mapping data flows, organizations can strengthen their cardholder data environment (CDE) and detect potential vulnerabilities or unauthorized network traffic before it leads to a breach.

Organizations across the payment card industry (PCI) often face challenges meeting evolving compliance standards. One of the most complex updates in the latest PCI DSS framework is Requirement 6.4.3, which focuses on change management and security validation. For e-commerce businesses especially, maintaining compliance requires careful planning, continuous monitoring, and adaptable security controls.

Is your organization prepared to comply with PCI DSS 6.4.3? Request a consultation with RSI Security to strengthen your compliance posture and protect sensitive payment data.

Organizations that process credit card payments must follow the Payment Card Industry Data Security Standard (PCI DSS)a global framework designed to protect cardholder data from breaches and fraud. One of the key requirements is implementing a strong account lockout policy. This security control helps prevent unauthorized access, reduces the risk of brute-force attacks, and strengthens overall system integrity.

In this article, we explain how to create an effective PCI DSS account lockout policy, how it aligns with PCI DSS v4.0 requirements, and why it is essential for a PCI-compliant information security program.

In today’s evolving threat landscape, cybercriminals continuously target sensitive payment data. To combat these risks, PCI DSS Requirement 10 emphasizes the importance of audit logging and security monitoring. This requirement mandates detailed tracking of user activities and system events, helping organizations detect threats early and prevent potential breaches.

The PCI DSS 4.0 requirements, released in March 2022, build upon previous versions to strengthen data protection across all payment environments. While many core controls remain consistent, the latest update places increased focus on areas such as risk mitigation, access control, and PCI logging requirements.

Understanding and implementing these logging controls is essential for detecting suspicious activity, maintaining visibility into system events, and achieving ongoing PCI DSS compliance.

Protecting cardholder and payment data from cyberattacks starts with a secure network. Following PCI network security best practices is essential for organizations that store, process, or transmit sensitive cardholder information. The PCI Security Standards provide clear guidance to help businesses implement robust network security measures, reduce risks, and maintain compliance.

In this guide, we’ll explore the key standards, their objectives, and practical strategies for meeting PCI compliance network security requirements.

An Approved Scanning Vendor (ASV) is a PCI-certified company that performs external network vulnerability scans to help organizations identify security weaknesses. Merchants of all sizes are required by the PCI Security Standards Council to conduct these scans regularly to detect vulnerabilities before attackers can exploit them.

In the sections below, we’ll explain how an Approved Scanning Vendor works and how ASVs help businesses maintain PCI compliance.

The Payment Card Industry Security Standards Council (PCI SSC) requires any business that processes card or electronic payments to comply with strict regulations designed to protect cardholder data. A key part of maintaining PCI DSS compliance is completing a PCI compliance scan, which must be performed quarterly by an Approved Scanning Vendor (ASV).

These scans validate that your security controls effectively identify and mitigate vulnerabilities that could expose sensitive payment information. Below is a clear walkthrough of how PCI compliance scans work, along with preparation tips to help your organization pass ASV testing with confidence.
