Before creating security alerts with Azure Monitor in the subscription, which Azure resource should you create first?

An Azure Log Analytics workspace is essential because Azure Monitor uses it as a central repository for collecting, storing, and analyzing log data from various Azure resources, including security-related logs. Without a workspace, Azure Monitor cannot store the data needed to trigger security alerts. An Azure Automation account is used for automating tasks, not for log collection. An Azure Event Hub is for real-time data ingestion and streaming, not for persistent log storage and analysis for alerting. An Azure Storage account can store data but lacks the built-in querying and alerting capabilities that a Log Analytics workspace provides for Azure Monitor.
