Which SIEM feature aggregates all similar events into a single summary report?

• A. Data Aggregation
• B. Log Retention
• C. System and Device Log Monitoring
• D. Object Access Auditing

Answer: (A)

Data aggregation is the process of collecting similar events from across the environment and combining them into a single, summarized view. In a SIEM, you often encounter many identical or related events (like repeated failed logins from the same source). Aggregation condenses these into one summary report that shows how many occurrences occurred, the time window, and shared attributes, making it easier to spot trends and reduce noise for investigators. Log retention deals with how long logs are stored, not how events are summarized. System and Device Log Monitoring focuses on collecting and watching logs in real time, not on condensing them into summaries. Object Access Auditing records who accessed what resources, which is about access activity rather than aggregating general events.
