Statistical data is crucial for detecting anomalies within a network because it provides a baseline of normal behavior.
Anomaly detection involves comparing current network data against historical statistical data to identify deviations from expected patterns.
This method helps in identifying unusual activities that could signify a security threat, such as unusual login attempts, data transfers, or access patterns.
Statistical data analysis tools use metrics such as mean, variance, and standard deviation to flag anomalies, aiding in proactive threat detection.
