To search for specific criteria in Amazon Web Services (AWS) logs and generate incidents using Microsoft Sentinel , the configuration process follows a structured sequence according to Microsoft Sentinel documentation and the Azure Sentinel playbook for AWS integration.
* Add the Amazon Web Services (AWS) connector
* Before Sentinel can analyze AWS data, you must integrate AWS logs using the Amazon Web Services data connector . This connector streams AWS CloudTrail and other AWS log data into your Sentinel workspace. Microsoft's documentation states: "Use the Amazon Web Services (AWS) connector to stream CloudTrail events and security logs into Microsoft Sentinel for analysis and alerting."
* Without this connector, Sentinel cannot query or detect AWS-specific activities.
* Create a custom analytics rule that uses a scheduled query
* Once data ingestion is established, you create an analytics rule in Sentinel using a scheduled query to continuously search for specific conditions (e.g., unauthorized access attempts, changes to VPC settings, etc.).
* Microsoft specifies: "Custom analytics rules run KQL queries on a schedule to detect specific patterns or anomalies across ingested data sources."
* Set the alert logic
* After defining your rule, you configure the alert logic to determine when Sentinel should trigger an alert or incident. This includes setting thresholds, event frequency, severity levels, and entity mappings.
* Microsoft Sentinel's official guidance notes: "Alert logic defines the conditions under which an alert is generated from the query results."
