SIEM defined
SIEM (Security Information and Event Management) is a platform that centrally collects, normalizes, and correlates logs and events from all IT systems in an enterprise. It gathers logs scattered across firewalls, servers, switches, applications, and identity systems, applying rules and machine learning to identify anomalous behavior.
Core SIEM capabilities
Core capabilities of a modern SIEM include:
- Log collection: agent or agentless collection of system logs
- Normalization: convert logs from different vendors and formats into a unified schema
- Correlation rules: detect attack chains based on ATT&CK, Diamond, and similar models
- Alert classification: distinguish info, low, medium, high, critical events
- Forensics & reporting: event timeline, attack-path reconstruction, compliance report export
The physical-layer blind spot and how CloudSino fills it
Most SIEM deployments focus on network- and application-layer logs and barely collect anything from data center physical infrastructure — server BMC events, PDU power-loss alerts, temperature/humidity threshold breaches, leak detection, rack access control. This means physical attacks, environmental failures, and hardware tampering are entirely outside SIEM visibility. CloudSino DCOS feeds physical-layer telemetry (IPMI/Redfish/SNMP) into the unified alert pipeline and integrates with the SIEM, closing the final gap.
