Which goal aligns with the need for regular network monitoring?

Regular network monitoring is crucial for maintaining the security and integrity of cardholder data environments, and aligns with Goal 5 of the PCI DSS, which focuses on monitoring and testing networks. This goal emphasizes the need for implementing robust mechanisms to monitor all access to network resources and cardholder data.

By continuously monitoring networks, organizations can detect and respond to security vulnerabilities and incidents in real-time or near real-time. This proactive approach allows for identifying unauthorized access and potential anomalies that could indicate a breach, ensuring that appropriate measures are taken to protect sensitive information. Regular network monitoring also supports compliance with various security standards and helps organizations maintain a secure environment by regularly reviewing logs and monitoring trends over time.

This aligns with the overall goal of safeguarding cardholder information and is vital for achieving compliance with PCI DSS requirements.
