Splunk can help organizations detect security threats and attacks by analyzing patterns in large volumes of machine data. As attacks have evolved beyond simple signatures to target behaviors, a behavioral approach is needed to understand adversary goals and methods. Splunk supports pattern modeling and adaptation to anticipate attack vectors. It detects suspicious patterns and anomalies by establishing baselines of normal behavior and monitoring for deviations. This helps security analysts take an "actor view" to gain insights into persistent threats.
