200-201 Security Monitoring Practice Question
Which component of a SIEM is responsible for converting log data from various sources into a standard format?
⚠ Common exam trap
It's easy for candidates to confuse normalization with aggregation, thinking that simply collecting logs from multiple sources is enough to make them comparable, when in fact normalization is the crucial step that standardizes the data format.

Correct answer & explanation
✓
Normalization
Normalization is the SIEM component that parses incoming log data from diverse sources (e.g., syslog, Windows Event Log, NetFlow) and maps the fields into a common, standardized schema. This process ensures that fields like source IP, destination IP, and timestamp are consistently named and formatted, enabling effective correlation and analysis across heterogeneous devices.
