Which edition to choose?

▪ If you are unsure, choose Standard

▪ You can always upgrade to DataCenter, without reinstall

▪ How?▪ DISM /Online /Get-TargetEdition

▪ DISM /Online /Set-Edition:ServerDatacenter /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

Onsight

Server Core

▪ A more security-enhanced, less resource-intensive installation option

▪ An installation that cannot be converted to full graphical shell version of Windows Server 2016

▪ The default installation option for Windows Server 2016

▪ Managed locally by using sconfig.cmd and Windows PowerShell

▪ With remote management enabled, you rarely need to sign in locally!

Shielded VM’s

#2

Onsight

Administrator privileges – Central risk?

▪ Microsoft know that administrators have the keys to the kingdom; they gave them those keys decades ago

▪ But those administrators privileges are being compromised through social engineering, bribery, coercion, private initiatives

Stolen admincredentials

Phishing attacks

Insiderattacks

Onsight

Who can become Domain Admin (or more)?

▪ Built-in Administrators

▪ Server Operators

▪ Account Operators

▪ Backup Operators

Onsight

What is Shielded VM ?

▪ “The data and state of a shielded VM are protected against inspection, theft and tampering from both malware and datacenter administrators1.”

1 fabric admins, storage admins, server admins, network admins

Onsight

Shielded VM security assurance goal

▪ Encryption & data at-rest/in-flight protection▪ Virtual TPM enables the use of Bitlocker within a VM

▪ Both Live Migration and VM-state are encrypted

▪ Admin-lockout▪ Host administrators cannot access guest VM secrets

▪ Attestation of health▪ VM-workloads can only run on “healthy” hosts

Onsight

Virtual TPM – Generation 2 VM’s

▪ Windows Server 2016 Hyper-V allows you to add a Virtual TPM chip to your Virtual Machine, which allows you encrypt your VM using Bitlocker.

▪ On Generation 1 VM, you can use

Key Storage Drive

Onsight

Host Guardian Service

Hyper-V enhancements

#3

Onsight

Nested virtualization

▪ With Nested Virtualization Windows Server 2016 Hyper-V allows you to run Hyper-V Servers inside Hyper-V Virtual Machines.

▪ Great feature for lab environments and Containers.

Onsight

Memory management – Hot-Add memory

▪ Administrators can now increase, or decrease VM memory without VM downtime.

▪ Cannot be decreased lower than current demand, or increased higher than physical system memory.

▪ The guest must be running Windows 10 or Windows Server 2016.

▪ Dynamic memory is not used for the VM.

▪ Can be a Generation 1 or Generation 2 VM.

Onsight

Virtual network adapter enhancements

▪ Administrators now have the ability to add or remove virtual NICs (vNICs) from a VM without downtime.

▪ Enabled by default, with Gen 2 VMs only.

▪ Any supported Windows or Linux guest operating system can use the hot-add/remove vNIC functionality.

▪ vNIC identification: New capability to name vNIC in VM settings and see name inside guest operating system.

Onsight

VM Configuration

▪ Can be updated manually

▪ No reversible – Beware!

▪ Binary format instead of .XML

Onsight

Virtual Machine Secure Boot

▪ Secure Boot - When VM starts, the firmware checks the signature of each piece of boot software, including firmware drivers and the operating system. If the signatures are good, the VM boots, and the firmware gives control to the operating system.

▪ Supported OS inside Generation 2 VM:▪ Windows 8/2012->

▪ Ubuntu 14.04->

▪ SUSE Linux Enterprise Server 12->

▪ RHEL 7.0->

▪ CentOS 7.0->

Onsight

Production checkpoints▪ Easily create “point in time” images of a

virtual machine, which can be restored later on in a way that is completely supported for all production workloads.

▪ Volume Snapshot Service (VSS) is used inside Windows virtual machines to create the production checkpoint instead of using saved state technology.

▪ No change to user experience for taking/restoring a checkpoint. Restoring a checkpoint is like restoring a clean backup of the server.

▪ Production as default: New virtual machines will use production checkpoints with a fallback to standard checkpoints.

Onsight

PowerShell Direct

▪ Bridge the boundary between Hyper-V host and guest VM in a secure way to issue PoSh cmdlets and run scripts easily.

▪ Currently supported on WS2016/W10 guest on WS2016/W10 host

▪ No need to configure PS Remoting

▪ No need network connectivity

▪ Just need the guest credentials

▪ Can only connect to particular guest from that host.

Enter-PSSession -VMName VMName

Invoke-Command -VMName VMName -ScriptBlock { Fancy Script }

Onsight

Hyper-V Manager improvements

▪ Support for alternate credentials

▪ Connecting via IP address

▪ Connecting via WinRM (port 80)

▪ Downlevel support
