Ever since the days of Windows Server 2012, Microsoft has enabled PowerShell remoting by default within its operating systems. This means that an authorized administrator is able to establish a PowerShell session with the machine and manage it from elsewhere. While having the ability to use PowerShell to remotely manage a VM is certainly convenient, you might be able to make your network just a little bit more secure by turning off PowerShell remoting for your Hyper-V virtual machines. You will still be able to use PowerShell remoting to manage your VMs, you will just force the bad guys to jump through a few extra hoops.
