System Center

Microsoft released System Center 1801 Semi-Annual Channel

Microsoft just release the first Semi-Annual Channel release for System Center, called System Center, version 1801. This is the first release which now comes out to support the Windows Server Semi-Annual Channel releases like 1709 and also brings some new features and performance improvements.

System Center, version 1801 is the first of our Semi-Annual Channel releases delivering new capabilities at a faster cadence. Semi-Annual Channel releases have an 18-month support policy. In addition, we will continue to release in the Long-Term Servicing Channel (LTSC) at a lower frequency. The LTSC will continue to provide 5 years of mainstream support followed by 5 more years of extended support.

What’s in System Center, version 1801?

System Center, version 1801 focuses on enhancements and features for System Center Operations Manager, Virtual Machine Manager, and Data Protection Manager. Additionally, security and bug fixes, as well as support for TLS 1.2, are available for all System Center components including Orchestrator, Service Management Automation, and Service Manager.

I am pleased to share the capabilities included in this release:

 

  • Support for additional Windows Server features in Virtual Machine Manager: Customers can now setup nested virtualization, software load balancer configuration, and storage QoS configuration and policy, as well as migrate VMware UEFI VM to Hyper-V VM. In addition to supporting Windows Server, version 1709, we have added support for host monitoring, host management, fall back HGS, configuration of encrypted SDN virtual network, Shielded Linux VMs on Hyper-V management, and backup capabilities.
  • Linux monitoring in Operations Manager: Linux monitoring has been significantly improved with the addition of a customizable FluentD-based Linux agent. Linux log file monitoring is now on par with that of Windows Server (Yes, we heard you! Kick the tires, it really works).
  • Improved web console experience in Operations Manager: The System Center Operations Manager web console is now built on HTML5 for a better experience and support across browsers.
    Updates and recommendations for third-party Management Packs: System Center Operations Manager has been extended to support the discovery and update of third-party MPs.
  • Faster, cost-effective VMware backup: Using our Modern Backup Storage technology in Data Protection Manager, customers can backup VMware VMs faster and cut storage costs by up to 50%.
  • And much more including Linux Kerberos support and improved UI responsiveness when dealing with many management packs in Operations Manager. In Virtual Machine Manager, we have enabled SLB guest cluster floating IP support, added Storage QoS at VMM cloud, added Storage QoS extended to SAN storage, enabled Remote to VMs in Enhanced Session mode, added seamless update of non-domain host agent, and made host Refresher up to 10X faster.

You can get System Center, version 1801 from the Evaluation Center or the Volume Licensing Service Center.

Windows SpeculationControl PowerShell

Microsoft Guidance to protect against speculative execution side-channel vulnerabilities on Windows, Windows Server and Azure (Meltdown & Spectre)

Microsoft very quickly responded to the speculative execution side-channel vulnerabilities also called Meltdown and Spectre which affect many modern processors and operating systems, including chipsets from Intel, AMD, and ARM. Microsoft released some guidance how you should protect your devices against these vulnerabilities. The Microsoft Security Defense Team also published an article with guidance and more details on this: ADV180002 | Guidance to mitigate speculative execution side-channel vulnerabilities

In this blog post I tried to quickly summarize the information and link it to the right websites.

Summary

Microsoft is aware of detailed information that has been published about a new class of vulnerabilities referred to as speculative execution side-channel attacks. This industry-wide attack method takes advantage of out-of-order execution on many modern microprocessors and is not restricted to a single chip, hardware manufacturer, or software vendor. To be fully protected, updates are required at many layers of the computing stack and include software and hardware/firmware updates. Microsoft has collaborated closely with industry partners to develop and test mitigations to help provide protections for our customers. At the time of publication, Microsoft had not received any information to indicate that these vulnerabilities have been used to attack our customers.

Note This issue also affects other operating systems, such as Android, Chrome, iOS, and MacOS.

Warning

Microsoft addressed protect against speculative execution side-channel vulnerabilities in the latest Windows Updates. However, customers who only install the Windows January 2018 security updates will not receive the benefit of all known protections against the vulnerabilities. In addition to installing the January security updates, a processor microcode, or firmware, update is required. This should be available through your device manufacturer. Surface customers will receive a microcode update via Windows update.

Guidance for Windows Client

Customers should take the following actions to help protect against the vulnerabilities:

  1. Verify that you are running a supported antivirus application before you install OS or firmware updates. Contact the antivirus software vendor for compatibility information.
  2. Apply all available Windows operating system updates, including the January 2018 Windows security updates.
  3. Apply the applicable firmware update that is provided by the device manufacturer

Windows-based machines (physical or virtual) should install the Microsoft security updates that were released on January 3, 2018. See Microsoft Security Advisory ADV180002 for updates for the following versions of Windows.

Read full guidance for Windows Client here: Windows Client Guidance for IT Pros to protect against speculative execution side-channel vulnerabilities

Guidance for Windows Server

Customers should take the following actions to help protect against the vulnerabilities:

  1. Apply the Windows operating system update. For details on how to enable this update, see Microsoft Knowledge Base Article 4072699.
  2. Make necessary configuration changes to enable protection.
  3. Apply an applicable firmware update from the OEM device manufacturer.

Windows Servers-based machines (physical or virtual) should get the Windows security updates that were released on January 3, 2018, and are available from Windows Update.

  • Windows Server, version 1709 (Server Core Installation) KB4056892
  • Windows Server 2016 KB4056890
  • Windows Server 2012 R2 KB4056898
  • Windows Server 2012 Not available yet
  • Windows Server 2008 R2 KB4056897

Your server is at increased risk if it is in one of the following categories:

  • Hyper-V hosts
  • Remote Desktop Services Hosts (RDSH)
  • For physical hosts or virtual machines that are running untrusted code such as containers or untrusted extensions for database, untrusted web content or workloads that run code that is provided from external sources.

There for Microsoft posted some additional registry keys to mitigations on servers. Microsoft also added some extra registry keys if you are running older versions of Hyper-V.

Read the full guidance for Windows Server and the registry keys here: Windows Server guidance to protect against speculative execution side-channel vulnerabilities

Guidance for Virtual Machines running on Hyper-V

In addition to this guidance, the following steps are required to ensure that your virtual machines are protected from CVE-2017-5715 (branch target injection):

  1. Ensure guest virtual machines have access to the updated firmware. By default, virtual machines with a VM version below 8.0 will not have access to updated firmware capabilities required to mitigate CVE-2017-5715. Because VM version 8.0 is only available starting with Windows Server 2016, users of Windows Server 2012 R2 or earlier must modify a specific registry value on all machines in their cluster.
  2. Perform a cold boot of guest virtual machines.Virtual machines will not see the updated firmware capabilities until they go through a cold boot. This means the running VMs must completely power off before starting again. Rebooting from inside the guest operating system is not sufficient.
  3. Update the guest operating system as required. See guidance for Windows Server.

Read the full guidance for Guest Virtual Machines here: Protecting guest virtual machines from CVE-2017-5715 (branch target injection)

Guidance for Surface Devices

Microsoft will provide UEFI updates for the following devices:

  • Surface Pro 3
  • Surface Pro 4
  • Surface Book
  • Surface Studio
  • Surface Pro Model 1796
  • Surface Laptop
  • Surface Pro with LTE Advanced
  • Surface Book 2

The updates will be available for the above devices running Windows 10 Creators Update (OS version 15063) and Windows 10 Fall Creators Update (OS version 16299). You will be able to receive these updates through Windows Update or by visiting the Microsoft Download Center.

Read full guidance for Surface Devices here: Surface Guidance for Customers and Partners: Protect your devices against the recent chip-related security vulnerability

Guidance for Azure

Microsoft has already deployed mitigations across the majority of our cloud services and is accelerating efforts to complete the remainder.

However, I always recommend that you also patch your operating systems and applications to be protected against other vulnerabilities.

Impact to Enterprise Cloud Services

Microsoft is not aware of any attacks on the Microsoft Cloud customers which leverage these types of vulnerabilities. Microsoft employs a variety of detection capabilities to quickly respond to any malicious activity in our enterprise cloud services.

Most of the Azure infrastructure has already received mitigations against this class of vulnerability. An accelerated reboot is occurring for any remaining hosts. Customers can check the Azure Portal for additional details.

All other enterprise cloud services such as Office 365, Dynamics 365, and Enterprise Mobility + Security have mitigations against these types of vulnerabilities. Microsoft engineering is continuing to perform analysis across the environments to confirm further protection.

Read full guidance for Microsoft Azure here: Microsoft Cloud Protections Against Speculative Execution Side-Channel Vulnerabilities

Guidance for Azure Stack

Azure Stack customers should take the following actions to help protect the Azure Stack infrastructure against the vulnerabilities:

  1. Apply Azure Stack 1712 update. See the Azure Stack 1712 update release notes for instructions about how to apply this update to your Azure Stack integrated system.
  2. Install firmware updates from your Azure Stack OEM vendor after the Azure Stack 1712 update installation is completed. Refer to your OEM vendor website to download and apply the updates.
  3. Some variations of these vulnerabilities apply also to the virtual machines (VMs) that are running in the tenant space. Customers should continue to apply security best practices for their VM images, and apply all available operating system updates to the VM images that are running on Azure Stack. Contact the vendor of your operating systems for updates and instructions, as necessary. For Windows VM customers, guidance has now been published and is available in this Security Update Guide.

Read full guidance for Microsoft Azure Stack here: Azure Stack guidance to protect against the speculative execution side-channel vulnerabilities

Guidance for SQL Server

The following versions of Microsoft SQL Server are impacted by this issue when running on x86 and x64 processor systems:

  • SQL Server 2008
  • SQL Server 2008 R2
  • SQL Server 2012
  • SQL Server 2014
  • SQL Server 2016
  • SQL Server 2017

IA64-based versions of SQL Server 2008 are not believed to be affected.

Microsoft made a list of different SQL Server scenarios depending on the environment that SQL Server is running in and what functionality is being used. Microsoft recommends that you deploy fixes by using normal procedures to validate new binaries before deploying them to production environments.

You can finde the list for scenarios and recommendations here: SQL Server guidance to protect against speculative execution side-channel vulnerabilities

There is also a list of updates for SQL Server available:

 

  • 4057122 Description of the security update for SQL Server 2017 GDR: January 3, 2018
  • 4058562 Description of the security update for SQL Server 2017 CU3 RTM: January 3, 2018

Windows SSH on WSL

Install and Configure OpenSSH Server on Windows 10 and Windows Server 1709

A couple of weeks ago I already wrote about how OpenSSH is now available on Windows 10. In this blog post I will cover how to install and configure OpenSSH Server on Windows 10 and Windows Server 1709.

Today, OpenSSH Client and Server on Windows are still in Beta, so they should only be used in secure test environments and not in production.

First you have to install the OpenSSH feature on your Windows machine. Remember that it needs to be the Windows 10 Fall Creators Update (1709) or Windows Server version 1709 or higher.

Windows OpenSSH Server

On Windows 10 you can also use the UI to install it.

Windows OpenSSH Server Folder

After the installation you can find the OpenSSH Server files and some more configuration options under C:\Windows\System32\OpenSSH

Now you need to configure the OpenSSH Server (sshd)

To enable authentication into an SSH server on Windows, you first have to generate host keys and repair the ACL on the host keys.

Configure OpenSSH Server on Windows

Windows SSH on WSL

Now you should be able to connect to the Windows Machine using SSH for an SSH client. Of course this can be the OpenSSH client or the SSH client which comes with the Windows Subsystem for Linux on Windows 10.

Azure Network Security Group SSH

If you are running OpenSSH Server on a Windows 10 or Windows Server 1709 virtual machine in Microsoft Azure, don’t forget to also configure the Network Security Group (NSG) to allow SSH inbound access on port 22.

Also check out how you can do SSH from PowerShell: Using SSH with PowerShell
