What capability do Security Incident and Event Management (SIEM) solutions provide in the context of insider threat prevention?

In the context of insider threat prevention, the correct capability provided by Security Incident and Event Management (SIEM) solutions is the ability to draw patterns for informed decision-making against cyberattacks. This is essential because insiders can often exhibit behaviors that deviate from normal patterns. By analyzing logs and events collected from various sources, SIEM solutions can identify anomalous activities that may indicate malicious insider behavior.

The capability to draw patterns allows organizations to establish a baseline of normal user behavior, which can then be compared against current activities. If a user suddenly begins accessing sensitive information they typically do not engage with, or if their login times change significantly, these deviations can trigger alerts. This proactive threat detection is key to mitigating risks before they escalate into data breaches or other harmful incidents.

While ensuring ongoing confidentiality, integrity, and availability of systems is important, it does not specifically focus on the behavior of individuals within the organization, which is critical in managing insider threats. Similarly, optimizing the use of digital evidence and minimizing investigation costs is relevant but does not directly address the detection and prevention of insider threats. Building custom queries and generating alerts do play a role in SIEM functionality but are more specific tools rather than the broader capability to identify patterns for decision-making against potential insider threats
