Why is establishing a "Security Baseline" important in QRadar?

Establishing a "Security Baseline" is crucial in QRadar because it provides a reference point for what constitutes normal network behavior and activity within an organization. By defining this baseline, security teams can monitor and detect deviations from this established norm. When abnormal behavior or activities are observed, these deviations can indicate potential security incidents, such as intrusions or malware infections. This proactive approach enables organizations to respond more effectively to threats, as they are better equipped to differentiate between typical and atypical activities in their network environments.

Having a well-defined security baseline also supports continuous monitoring and analysis, allowing analysts to investigate incidents with context. This leads to a quicker identification of true threats, ensuring that the organization's security posture remains robust and responsive.
