You need to observe the PCI-DSS (Payment Card Industry - Data Security Standards) guidelines if your organization store, transmit or process customer credit card data.
EventLog Analyzer ensures compliance of Payment Card Industry Data Security Standard (PCI-DSS) Requirement 10. This section mandates payment service providers and merchants to track and report on all access to their network resources and cardholder data through system activity logs. When something goes wrong in the network, the presence of logs in networked environment allows forensic analysis to pin-point the exact cause. Without system activity logs it would be difficult to determine the cause of a compromise.
