Correct answer & explanation
✓
Just-in-time VM access
Just-in-time (JIT) VM access is a feature of Microsoft Defender for Cloud that reduces exposure to brute-force attacks by locking down inbound traffic to VMs. It allows you to control when specific ports (e.g., RDP port 3389 or SSH port 22) are opened on demand, based on role-based access control (RBAC) and approved requests, and automatically closes them after a configured time window.
