What is a SIEM?
A SIEM (Security Information and Event Management) system collects, normalizes, correlates, and alerts on log data from across the environment. It provides a single pane of glass for security operations.
SIEM Core Functions
Key functions: log collection and normalization, real-time correlation and alerting, historical search and investigation, compliance reporting, and incident response workflow.

# Correlation: rule-based and ML-based
# Alerting: threshold, pattern, anomaly
# Dashboards: SOC analyst views
# Reporting: compliance evidenceAll lessons in this course
