Payment Card Industry (PCI) Data Security Standards Practice Test

Which statement best describes a PCI DSS requirement for network vulnerabilities?

1. All network vulnerabilities must be assessed monthly

2. An annual vulnerability assessment is adequate for PCI compliance

3. Vulnerability scans must be done quarterly and after significant changes

4. No vulnerability assessments are required

The correct answer is: Vulnerability scans must be done quarterly and after significant changes

The correct statement emphasizes the importance of regular and proactive measures in identifying and managing network vulnerabilities to maintain the security of payment card data. According to PCI DSS requirements, vulnerability scans are mandated to be conducted at least quarterly and following any significant changes to the network infrastructure. This approach ensures that any new security risks introduced by updates or changes in the system are promptly identified and mitigated. Regular scanning helps organizations stay ahead of potential threats and minimizes the window of vulnerability, which is crucial in protecting sensitive payment card information. Relying solely on annual assessments would not provide a sufficient level of scrutiny throughout the year, especially in dynamic environments where changes can occur frequently. Therefore, conducting scans quarterly and after significant changes aligns with best practices for maintaining PCI compliance and ensuring ongoing protection against newly discovered vulnerabilities.
