312-39 Question #125: Real Exam Question with Answer & Explanation

Question

Options

• ARule-based detection
• BHeuristic-based detection
• CAnomaly-based detection
• DSignature-based detection

Explanation

User and Entity Behavior Analytics (UEBA) is a cybersecurity process that uses machine learning, algorithms, and statistical analyses to detect abnormal behavior of users and entities within an organization. UEBA systems analyze patterns of behavior and can identify anomalies that deviate from the norm, which could indicate a potential security threat. Anomaly-based detection is the technique that aligns with UEBA’s functionality. It contrasts with: Rule-based detection, which relies on predefined rules to detect threats. Heuristic-based detection, which uses experience-based techniques. Signature-based detection, which depends on known patterns or signatures of malware to identify Anomaly-based detection systems are designed to be dynamic, continuously learning and establishing what is considered normal to identify deviations. This approach is particularly effective in identifying previously unknown threats, hence its alignment with UEBA. operations, including incident detection with Security Information and Event Management (SIEM) and enhanced incident detection with Threat Intelligence, which encompasses the use of UEBA for anomaly detection123.
