Instead: You recommend enabling just-in-time (JIT) VM access on all virtual machines.
Note:
Secure management ports - Brute force attacks often target management ports. Use these recommendations to reduce your exposure with tools like just-in-time VM access and network security groups.
Recommendations:
- Internet-facing virtual machines should be protected with network security groups
- Management ports of virtual machines should be protected with just-in-time network access control
- Management ports should be closed on your virtual machines
