What Is SIEM (Security Information and Event Management)?
SIEM — Security Information and Event Management — is the system security teams use to see an attack forming: it collects logs and events from across the environment, correlates them into patterns, and alerts when those patterns look like a threat. It is the operations center of enterprise security.
Collect, Correlate, Alert, Investigate
Collect
Logs and events from servers, network, apps, identity, and cloud.
Correlate
Rules and analytics link events into attack patterns.
Alert
Suspicious sequences raise prioritized security alerts.
Investigate
Analysts pivot through the evidence and respond.
Most SIEMs Never See the Management Plane
A typical SIEM ingests OS, network, and application logs — and stops there. Below that sits a second attack surface most deployments never watch: BMC logins, out-of-band configuration changes, firmware modifications, and hardware events. An attacker with management-plane access can persist below the operating system, invisible to every agent the SIEM relies on.
Sensaka is not a SIEM — it's the infrastructure platform that closes that gap. It collects hardware events, BMC access records, and configuration changes from the management plane, and can forward them to your SIEM, so security correlation finally includes the physical layer.
Common Questions About SIEM
What does SIEM stand for?
SIEM stands for Security Information and Event Management — a system that collects logs and security events from across an environment, correlates them, and raises alerts on suspicious patterns.
What is the difference between SIEM and monitoring?
Infrastructure monitoring watches health and performance; SIEM watches for security threats in logs and events. They overlap in data collection but answer different questions — and mature operations feed infrastructure events into the SIEM.
What are SIEM logs?
SIEM logs are the raw records ingested for analysis: authentication events, firewall logs, system logs, application events — and, in complete deployments, hardware and management-plane events like BMC logins and configuration changes.
What is SIEM as a service?
SIEM as a service (or managed SIEM) is SIEM delivered as a cloud/managed offering, where the provider runs the platform and often the 24/7 monitoring. It trades control and data locality for lower operational burden.
