Definition
Security Information and Event Management (SIEM) is a platform for centrally collecting, correlating, analysing and presenting security events from multiple sources.
Human Explanation
SIEM gathers Logs from different systems and helps identify relationships that may indicate a Threat or Incident.
Why it Matters
Combining information from multiple sources reveals events that may not be visible when individual Logs are analysed separately.
Conceptual Boundary
SIEM does not replace a security team. It supports analysis and decision-making but requires appropriate configuration and interpretation.
Practical Perspective
SIEM creates the greatest value when data from different systems forms one coherent view of organisational security.
