Business Context

Continuous security monitoring enables early detection of abnormal

behavior, malware, and unauthorized access. Excessive alerts, however,

increase the workload of operators and cybersecurity teams.

The Contradiction

More monitoring improves threat detection.

Fewer alerts improve operational focus.

Why It Exists

Security platforms often generate thousands of events daily, many of

which have little operational significance.

Direction

Prioritize alerts using risk scoring, behavioral analytics, and

automated correlation to ensure personnel receive only actionable

security information.
