This rule detects the deletion of Azure Log Analytics Workspaces, which is a significant action that can compromise the logging infrastructure essential for monitoring and auditing activities in an Azure environment. When an Azure Log Analytics Workspace is deleted, it not only results in the loss of centralized logging capabilities but can also represent a broader strategy of evading defense mechanisms. This detection rule is categorized under medium severity due to its implications on data integrity and security monitoring. The rule monitors Azure Monitor Activity logs for operational commands related to workspace deletion, associating the deletion with the caller's IP address. It provides guidance on responding to such an event, including the need to identify if the activity was part of broader malicious actions directed at the monitoring infrastructure.
