This rule detects the creation or modification of resource groups in Azure environments. Resource groups in Azure serve as logical containers for organizing and managing various Azure resources, such as virtual machines, databases, and networking components. The detection logic utilizes Azure activity logs to monitor specific write operations related to resource groups, identified by the event type 'MICROSOFT.RESOURCES/SUBSCRIPTIONS/RESOURCEGROUPS/WRITE'. When a resource group is successfully created or modified, relevant attributes such as time of event, user information, region, source IP, and request parameters are collected. The rule leverages Splunk's data ingestion capabilities to aggregate and present these events, allowing administrators to track changes and ensure that any modifications to the resource groups are legitimate and authorized. Potential misuse of this capability can occur during attempts to evade detection or manipulate cloud infrastructure for malicious purposes, positioning this detection rule as crucial for security monitoring in cloud environments.
