Exam SecOps-Pro Topic 1 Question 265 Discussion

Log Stitching primarily relies on the presence of common identifiers (like host, user, process ID, timestamps) to link events. While missing specific fields like 'destination_port' won't necessarily make the stitching 'fail' completely if the linking identifiers are present, it will certainly lead to an incomplete and less informative incident. The enriched context derived from these fields will be absent, making it harder for the analyst to understand the full scope of the network activity. XSIAM's 'Data Normalization' component, typically occurring during ingestion, is designed to ensure that logs from diverse sources are parsed and mapped to a consistent schema, extracting and populating critical fields. If normalization is misconfigured or the raw log itself lacks the data, stitching will still happen but with limited detail. Data Remapping is more about re-assigning existing fields, not fixing missing data from the source.
