SIEM
Definition
Platform that aggregates and correlates security events/logs (Splunk, Sentinel, etc.).
For executives (CEO·CISO)
The hub for security visibility and compliance (audit logs); streaming email verdicts in pulls the whole attack picture together. Commonly missed: collecting logs nobody reviews just burns budget — define which alerts trigger which response (rules, owner, SLA) for the SIEM to actually pay off.
