Detecting rare and unusual processes with OOTB machine learning

In the realm of security operations, differentiating between common and rare host processes is vital for identifying potential security threats. Elastic Security offers tools to detect unusual processes through machine learning, focusing on rare anomalies to streamline threat detection. By using Elastic's unsupervised machine learning, users can create models that highlight and score atypical processes, prioritizing those most unusual in the environment. The system provides prebuilt anomaly detection jobs and allows for customization to fit specific data sources and needs. Understanding and analyzing these rare processes involves investigating whether they pose a security threat or are benign, providing feedback to refine detection. Elastic facilitates this with out-of-the-box configurations and the ability to create tailored anomaly detection jobs, emphasizing the importance of modeling normal activity to identify abnormalities effectively.
