Exam C1000-162 Topic 5 Question 66 Discussion

Behavioral rule test parameters in QRadar SIEM are crucial for configuring how anomaly detection functions within rules. Here's a breakdown of each parameter:
* Season:This is themost importantparameter. It defines the historical time period used to establish a baseline of "normal" behavior. Consider the nature of the traffic you're monitoring when choosing a season:
* Network traffic with human interaction: A season of 1 week might be appropriate.
* Daily patterns: A season of 24 hours would be more suitable.
* Current traffic level:Represents the current value of the property being monitored by the rule (e.g., number of login failures, bandwidth usage, etc.).
* Predicted value:This is an estimation of what the traffic level "should" be, based on the established season and historical trends.
How the Parameters Work Together
Behavioral rules primarily identify deviations between theCurrent traffic leveland thePredicted valuewithin the context of the definedSeason. Significant discrepancies can trigger alerts.
