AZURE CLI RESOURCE LIFECYCLE

Azure CLI Resource Group Lifecycle Lab

Problem

Practice the full lifecycle of an Azure resource group safely in Cloud Shell.

Implemented

Created a resource group with Azure CLI, verified its properties, then removed it when the lab was complete.

Validated

Confirmed the resource group existed after creation and was gone after deletion.

AZURE PIM JUST-IN-TIME ACCESS

Azure PIM JIT RBAC Activation Lab

Problem

Replace standing Azure access with privilege that is time-bound and auditable.

Implemented

Configured eligible Azure RBAC access and activated a time-limited Reader role through Microsoft Entra PIM.

Validated

Checked activation and audit records to confirm the access window and least-privilege scope.

SIEM & SECURITY MONITORING
