What is the focus of Risk-Based Alerting (RBA)?

The focus of Risk-Based Alerting (RBA) is indeed to aggregate risk events that meet certain criteria for investigation. RBA is designed to help security analysts prioritize alerts based on the actual risk these events pose to an organization. By aggregating events that have been assessed to contribute to higher levels of risk, this approach allows analysts to focus their efforts on the most critical threats, rather than getting overwhelmed by a multitude of alerts that may not pose significant risks.

Through this method, security teams can efficiently assess which events require immediate attention and response, enabling a more effective and strategic use of resources. RBA increases the overall cybersecurity posture by ensuring that investigations are targeted at genuine threats that could impact the organization.

The other options address aspects of alerting and automation, but they do not capture the essence of RBA's focus on risk aggregation and prioritization. For example, creating alerts solely based on user activity does not incorporate a risk-based perspective. Similarly, correlating network performance metrics with alerts is more about performance monitoring than risk assessment. Automating responses based on event severity is also important but falls short of the comprehensive strategy that RBA employs in prioritizing and aggregating events with a heightened risk assessment.
