How often does PCI DSS recommend reviewing logs?

The recommendation to review logs at least daily aligns with the PCI DSS requirements for monitoring and testing networks. Daily log reviews are crucial because they help detect and respond to security incidents in a timely manner. This frequency allows organizations to identify suspicious activities, potential breaches, or system performance issues before they escalate. By engaging in daily monitoring, entities can ensure a proactive approach to safeguarding cardholder data and assessing the effectiveness of their security measures.

The PCI DSS emphasizes the importance of ongoing security management, which includes regular monitoring of access and activity logs to quickly identify anomalies. While other frequencies such as weekly, monthly, or yearly reviews may also be important in a broader risk management strategy, they do not provide the immediacy required for effective incident response, which is why the recommendation for daily reviews is particularly highlighted.
