 Beyond threat detection, a SIEM system is also useful for compliance monitoring and auditing. Many regulations and standards (such as the Payment Card Industry Data Security Standard [PCI DSS], the Health Insurance Portability and Accountability Act [HIPAA], the General Data Protection Regulation [GDPR], and International Organization for Standardization [ISO] 27001) mandate that organizations log certain security-related events and preserve audit trails of system activity.
