A cloud security architect is evaluating a new Security Information and Event Management (SIEM) solution for a hybrid cloud environment. The primary concern is ensuring that security events from both on-premises data centers and various public cloud services are normalized and correlated effectively. Which key capability of a cloud SIEM is most critical for addressing this specific concern?
- AOrchestration and automation playbooks
- BAutomated threat hunting
- CMulti-cloud data ingestion and parsing
- DUser and Entity Behavior Analytics (UEBA)
Show answer & explanationAnswer & explanation
Correct answer: C. Multi-cloud data ingestion and parsing
Effective normalization and correlation across a hybrid environment directly depend on the SIEM's ability to ingest, parse, and understand data from diverse sources (on-prem and multiple clouds).
Why the other options are wrong
- A. Orchestration and automation playbooks are for response actions, not for the initial processing and correlation of raw event data.
- B. Automated threat hunting is a function that uses processed data, but it's not the core capability for normalizing and correlating diverse data sources.
- D. UEBA is an analytics feature that operates on normalized data, but it's not responsible for the initial normalization and correlation across different environments.
Cloud SIEM Data Ingestion & Parsing
The ability of a cloud-native Security Information and Event Management (SIEM) system to collect, process, and structure security event data from a wide variety of cloud services and on-premises sources.
- Crucial first step for any SIEM functionality.
- Handles different log formats and APIs.
- Enables subsequent normalization and correlation.
Memory trick: SIEM first needs to 'eat' all the data to make sense of it.
