1. Introduction

The Payment Card Industry Data Security Standard (PCI DSS) is a set of security requirements designed to ensure that all companies that process, store or transmit credit card information maintain a secure environment. Adherence to the standard is mandatory for any merchant that accepts or processes payments by major credit cards including Visa, Mastercard, American Express and Discover. The goals of PCI DSS are to protect cardholder data and reduce the risk of data breaches. Penetration testing, also known as pen testing, is a method of evaluating the security of a computer system or network by safely attempting to exploit vulnerabilities. The goal of penetration testing is to identify security weaknesses that an external attacker could leverage to gain unauthorized access to systems and data.

Penetration testing aims to simulate the techniques used by real-world attackers. Authorized security professionals may attempt to circumvent security features by exploiting known vulnerabilities, or by finding new flaws in the system. Activities can include attempting to gain access to systems, escalate privileges, and exfiltrate data. The findings from penetration testing enable organizations to strengthen their security measures proactively.

Some key requirements of PCI DSS include building and maintaining secure networks, protecting cardholder data, implementing strong access control measures, regularly monitoring and testing networks, and maintaining an information security policy. Achieving and maintaining PCI DSS compliance is critical for any business that handles sensitive payment card data.

2. Why Conduct Penetration Testing for PCI DSS Compliance?

PCI DSS explicitly requires all merchants and service providers to conduct regular penetration testing to maintain compliance. One of the Requirements in compliance states that penetration testing must be carried out at least annually, as well as after any significant infrastructure or application changes to the environment.


Penetration testing is a direct method of evaluating the real-world effectiveness of security controls. It uncovers vulnerabilities that may be overlooked during day-to-day operations and internal audits. PCI DSS penetration testing also assesses whether proper segmentation is in place between the cardholder data environment and other networks. Most importantly, it demonstrates due diligence in protecting cardholder information from unauthorized access.

3. What are the Scope and Objectives of PCI DSS Compliance Penetration Testing?

The scope of PCI DSS penetration testing includes all system components within or connected to the cardholder data environment, such as servers, applications, network devices and perimeter firewalls. The tester should attempt attacks from both outside and inside the network.

The objectives are:

  • Identify potential entry points for network intrusions
  • Evaluate exposure of cardholder data and related systems
  • Test configuration and effectiveness of security controls
  • Exploit identified vulnerabilities to gain access to systems
  • Demonstrate impact on cardholder data if vulnerabilities are exploited
  • Provide remediation guidance based on findings

4. Key Considerations for PCI DSS Compliance Penetration Testing

4.1 Some key factors to consider when conducting PCI DSS penetration tests include:

  • Properly scoping the cardholder data environment and all connected systems
  • Using a combination of automated and manual tools and techniques
  • Testing all layers of infrastructure from network to application
  • Ensuring both external and internal testing is performed
  • Adhering to the Rules of Engagement and getting appropriate sign-offs
  • Using qualified information security professionals with PCI experience
  • Producing comprehensive documentation with detailed findings
  • Identifying vulnerabilities with proof-of-concept exploits
  • Focusing on the impact on cardholder data and related systems

Businesses should develop a formal remediation plan based on the report’s recommendations. Common remediation steps include patching known vulnerabilities, improving configuration standards, implementing additional controls, expanding the scope of PCI compliance, and re-assessing any changes after implementation.

5. Best Practices for PCI DSS Compliance Penetration Testing

5.1 Best practices to ensure PCI DSS penetration testing is thorough and effective:

  • Maintain an up-to-date asset inventory of the full scope of systems
  • Use penetration testers specifically experienced with PCI DSS
  • Provide the latest network diagrams and information to testers
  • Ensure scoping aligns with how card data flows through systems
  • Schedule tests well in advance to allow sufficient time
  • Implement an efficient vulnerability management program
  • Integrate penetration testing with other security assurance functions
  • Establish ongoing authorization for penetration testers to avoid delays
  • Manage relationships with third-party penetration test vendors
