Detection
Sensitivity (Scan detection only.) Select a sensitivity level so as to reduce false
positives in your network. If you choose low sensitivity, then scan
thresholds and sample times are set low, so you will have fewer logs and
false positives; however some traffic anomaly attacks may not be
detected.
If you choose high sensitivity, then scan thresholds and sample times are
set high, so most traffic anomaly attacks will be detected; however you
will have more logs and false positives.
Block
