Sysmon Events

Sysmon (System Monitor) is a Windows system service and device driver that logs system activity to the Windows event log, providing detailed visibility into process creation, network connections, file modifications, registry changes, and more. By capturing granular information, such as parent processes, hash values, command lines, and timestamps—Sysmon generates high-value telemetry for incident response and threat hunting. Its advanced filtering capabilities allow analysts to enable or disable specific events, reducing noise while preserving critical data. Sysmon's event ID 1 (process creation), event ID 3 (network connect), and event ID 11 (file creation time change) are often leveraged in SIEM dashboards, EDR integrations, and custom playbooks. With persistent logging, native integration into Windows Security Event Logging, and a lightweight footprint, Sysmon is widely adopted by security operations centers to detect malicious activity, map attack chains, and provide forensic evidence for compliance audits.
