SIEM Processing Sequence

1️⃣ Collection Logs and events are collected from servers, applications, network devices, endpoints, and cloud platforms. 2️⃣ Parsing & Normalization Raw logs are parsed and converted into a common, standardized format so events from different sources can be compared and analyzed. 3️⃣ Aggregation Similar or repetitive events are grouped together to reduce noise and improve performance (for example, multiple failed logins from the same source). 4️⃣ Correlation Related events from different sources are linked together to detect attack patterns and identify real security incidents.
