According to the security policy you set up, Azure Security Center can enable just-in-time (JIT) access on your existing VMs as well as on your newly created VMs. When JIT VM access is enabled, Azure security Center closes traffic to the ports defined by creating the Network security Group rules. If necessary, you can request to open the required port for the approved period of time for the IP addresses approved for the VM and only for users with the appropriate permissions. Requests are saved in the Azure Activity Log, so you can easily monitor and control access. You can also enable JIT VM access, configure them with policy, and request access through PowerShell cmdlets. These new features are available within the Azure Security Center standard pricing tier and are free during the first 60 days.
