To keep your Business running, It’s important to secure and monitor your data. One of the security measures is doing Vulnerability assessments in your datacenter(s) to see the status and results for remediation. With Microsoft Azure Arc Defender for Cloud you can do a SQL Server vulnerability assessment in your on-premises datacenter or anywhere with the Azure Arc agent running. Here you find more information about Azure Arc enabled SQL Server
Microsoft Defender for Cloud on Azure Arc enabled SQL Server
Here I activated Microsoft Defender for Cloud on Azure Arc enabled SQL Server, and Azure Defender for Cloud is doing a SQL vulnerability assessment to get the security status and results for remediation.
On this same Azure portal page you will see the Vulnerability assessment findings.
When you Open a Vulnerability finding, you get more information and the remediation for the issue.
Here you see the complete Resource Health of the Azure Arc enabled SQL Server.
Look at the Status of each severity.
Here you see all the vulnerability findings on these four databases.
When you do the remediation you will see the healthy status.
on the Passed tab.
Here I open only the OperationsManager database.
Now you see only the Vulnerability findings on this database.
Here you see a vulnerability finding on the SCOM database with the Remediation 🙂
You can make your Own Workbooks or use them from the Gallery.

Conclusion
With Azure Defender for Cloud vulnerability assessment and management you will learn a lot to set your Security Baseline on a higher level in your datacenter(s). Getting the right remediation of Microsoft to solve security issues is Great! You can do your assessments frequently to show your current status on demand. I Really like these Azure Hybrid Tools to make my work easier and the data more secure for the business.
Baseline security is very important to have that in place to keep your Servers more secure in your datacenter. You want Hybrid Servers like Azure Arc enabled servers for example to be secure running in your datacenter. This begins to secure and have up-to-date Server hardware running in your datacenter. Monitor for security updates and install Server hardware based on best practices from the vendor.
Then the Operating System like Windows Server 2022 standard needs the OS Baseline security. This is called:
When your Windows Servers are security compliant by the rules of the company and/or Security Officer, then we can have a look at the Well Architected Framework (WAF) for Azure Arc Enabled Servers. Here you find an
This security baseline applies guidance from the Microsoft cloud security benchmark version 1.0 to Azure Arc-enabled servers. The Microsoft cloud security benchmark provides recommendations on how you can secure your cloud solutions on Azure. The content is grouped by the security controls defined by the Microsoft cloud security benchmark and the related guidance applicable to Azure Arc-enabled servers.
When you have read about Azure Arc Well Architected Framework (WAF) and you have your security in place, we can start with Microsoft Azure Arc.
Before you start implementing Azure Arc, you must have seen this Awesome website of Azure Arc Jumpstart!
The Azure Arc Jumpstart is designed to provide a “zero to hero” experience so you can start working with Azure Arc right away!
The Jumpstart provides step-by-step guides for independent Azure Arc scenarios that incorporate as much automation as possible, detailed screenshots and code samples, and a rich and comprehensive experience while getting started with the Azure Arc platform.
Our goal is for you to have a working Azure Arc environment spun-up in no time so you can focus on the core values of the platform, regardless of where your infrastructure may be, either on-premises or in the cloud.
You can manage your compliance and security policies with Azure Arc enabled Servers, Kubernetes, or SQL Managed instances to make your hybrid solutions with
the Microsoft Azure Cloud in a secure environment. When you work with security by design based on OSI model with 7 security layers and use Microsoft Arc enabled servers, you get also more Azure Hybrid security features like Azure Defender for Cloud, and much more.

Security monitoring and compliance are important to keep you in control and to keep your environment safe. With Azure Arc enabled Kubernetes you get Azure Defender for Containers and Azure policy for security compliance to your Kubernetes Cluster.
Important: This is still in preview and should not be used in production environment yet until Microsoft makes it General Available for the world. Now you can test it in your test environment like me in my MVPLAB.
The Server Message Block (SMB) Protocol is a network file sharing protocol, and as implemented in Microsoft Windows is known as Microsoft SMB Protocol. The set of message packets that defines a particular version of the protocol is called a dialect. The Common Internet File System (CIFS) Protocol is a dialect of SMB. Both SMB and CIFS are also available on VMS, several versions of Unix, and other operating systems. Here you can see the versions of MS-CIFS and download free white papers
Today SMBv1 is a not save protocol and will be used by hackers for man in the middle attacks to compromise your data and systems. SMBv1 is a weak protocol and should not be used in your environment. There are still a lot of Windows Servers 2012 R2 in the world running in datacenters with SMBv1 by Default enabled. To make your Windows Server more secure, you can disable SMBv1 protocol via a Group Policy Object (GPO).
In the following steps we will disable SMBv1 on Windows Servers via GPO.
Open Group Policy Management in your Domain.
Click on Group Policy Object with your right mouse button.
Click on New.
Give your policy a Name.
I made also an temporary Exception policy.
Right click on your new Policy Object.
Click on Edit.
Go to Computer Configuration => Preferences => Windows Settings
Click on Registry.
Click on New and then on Registry Item.
Here you have to add the following Registry Properties:
Set these settings.
Set Path: HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters
Click on Apply for these Registry settings.
SMBv1 Disable setting is set in the Policy Object.
This is the path where we push the policy via GPO.
Here we Link the Existing GPO to the OU with the Windows Server 2012 R2
to disable SMBv1 Protocol.
Select your new Policy to disable SMBv1 Protocol.
We have now Linked the new GPO to Disable SMBv1
GPUpdate /force on your Server to disable SMBv1
To get the new GPO active on your Server.
When the Server gets a reboot, SMBv1 will be disabled by GPO again.
When you have maintenance window for updates for example, you can un-install the SMBv1 Feature in Server Manager. This procedure needs a restart of the Windows Server.
Go to Server Manager remove features.
Click on Remove Roles and Features.
Remove the mark at SMB 1.0/CIFS File Sharing Support Feature.
Click on Remove.
Click on Close and Reboot the Server
Now SMBv1 protocol on the Windows Server is disabled and will use a higher version of SMB like version 2.x or 3.x.
SMB over QUIC introduces an alternative to the TCP network transport, providing secure, reliable connectivity to edge file servers over untrusted networks like the Internet. QUIC is an IETF-standardized protocol with many benefits when compared with TCP:
All packets are always encrypted and handshake is authenticated with TLS 1.3
Parallel streams of reliable and unreliable application data
Exchanges application data in the first round trip (0-RTT)
Improved congestion control and loss recovery
Survives a change in the clients IP address or port
SMB over QUIC offers an “SMB VPN” for telecommuters, mobile device users, and high security organizations. The server certificate creates a TLS 1.3-encrypted tunnel over the internet-friendly UDP port 443 instead of the legacy TCP port 445. All SMB traffic, including authentication and authorization within the tunnel is never exposed to the underlying network. SMB behaves normally within the QUIC tunnel, meaning the user experience doesn’t change. SMB features like multichannel, signing, compression, continuous availability, directory leasing, and so on, work normally.
Client Server Handshake and Data transfer differences.
When you still have Windows Servers running with SMBv1 by default enabled, for security you should disable SMBv1 protocol as soon as possible! Otherwise you make it easy for hackers to compromise your data with man in the middle attacks. In Windows Server 2019 and higher SMBv1 is disabled by default. Have a look at SMB over QUIC in your test environment and learn how secure it is and how it works for your security and data.
Hope you started year 2022 in Good Health in a difficult pandemic time.
Starting 2022 by asking yourself, how is your Security by Design doing in 2022

Security and Learning is a ongoing process, I always say Learning on the Job 😉 is important to keep Up-to-Date every day of the week. Microsoft Tech Community platform and Microsoft Learning can support you to get the knowledge.
Microsoft and the community has a lot of good security information to start with for your Data and Systems to keep your business solution as save as possible. Here they write New blogposts for the community about Defender for Cloud
Keep in Mind “Security is only as strong as the weakest component in the Chain”
So keep your Security up-to-date and do assessments on vulnerabilities to keep your data and systems secure. Monitoring => Alerting => Remediation is 24/7/365 Process with Security people in the business.
Secured-core – recommended for the most sensitive systems and industries like financial, healthcare, and government agencies. Builds on the previous layers and leverages advanced processor capabilities to provide protection from firmware attacks.
In Windows Admin Center Security you can Configure Secured-Core :
Secured-Core in Windows Admin Center 21.10
You can activate 6 secured-Core feature :
Hypervisor Enforced Code Integrity (HVCI)
Boot DMA Protection
System Guard
Secure Boot
Virtualization-based Security (VBS)
Trusted Platform Module 2.0 (TPM2.0)
You now can simply activate the Security Feature.
Needs a Reboot
Hypervisor Enforced Code Integrity (HVCI) is enabled.
The Microsoft Security Configuration Toolkit enables enterprise security administrators to effectively manage their enterprise’s Group Policy Objects (GPOs). Using the toolkit, administrators can compare their current GPOs with Microsoft-recommended GPO baselines or other baselines, edit them, store them in GPO backup file format, and apply them via a domain controller or inject them directly into testbed hosts to test their effects. For more information, see Windows Security Baselines.
Baseline security policies for Windows Server 2022.
But what’s new in Microsoft Windows Server 2022?
Here we have some new Windows Server 2022 security features :
Secured-core server
Hardware root-of-trust
Firmware protection
Virtualization-based security (VBS)
Secure connectivity
Transport: HTTPS and TLS 1.3 enabled by default on Windows Server 2022
Secure DNS: Encrypted DNS name resolution requests with DNS-over-HTTPS
Server Message Block (SMB): SMB AES-256 encryption for the most security conscious
SMB: East-West SMB encryption controls for internal cluster communications
In the following steps you will see some of the security features of Microsoft Windows Server 2022.
When your Windows Server 2022 is running on a Hypervisor like Hyper-V, you can set Memory integrity under Windows Security to ON.
This prevents attacks from inserting malicious code into high security processes. When you set this security feature on, the Server needs a reboot to activate. Memory Integrity needs a reboot.
Windows Security Notifications.
By default Virus & Threat protection notification is active, when you want notifications about Microsoft defender firewall blocking a new application, you have to turn this feature on and select the firewalls.
In Windows security we have also ransomware protection.
Protect your files against threats like ransomware, and see how to restore files in case of an attack.
You can do this by Controlled folder access. Protect files, folders and memory on your Server from unauthorized changes by software.
Protected folders.
New in Windows Server 2022 is Tamper protection in Windows Security.
This Prevents others from tampering with important security features.
This was all Microsoft Windows Server 2022 security in the VM, but how about your Windows Server 2022 Hyper-V Hypervisors?
Hypervisor-protected Code Integrity (HVCI) is a virtualization based security (VBS) feature available in Windows. In the Windows Device Security settings, HVCI is referred to as Memory Integrity.
HVCI and VBS improve the threat model of Windows and provide stronger protections against malware trying to exploit the Windows Kernel. VBS leverages the Windows Hypervisor to create an isolated virtual environment that becomes the root of trust of the OS that assumes the kernel can be compromised. HVCI is a critical component that protects and hardens this virtual environment by running kernel mode code integrity within it and restricting kernel memory allocations that could be used to compromise the system.
Here you find a great video with a session of Jeff Woolsey Principal Program Manager at Microsoft. It’s all about What’s new in Windows Server 2022.
Conclusion
Start with Microsoft Windows Server 2022 today and make your test environment to play with Windows Server 2022 and Security.
Make your core business application solution more secure then ever, and let a ethical hacker do pen tests on your solution.
When you have security by default in your architectural designs, and test your Windows Server 2022 for production workloads it makes a big different to keep your environment and solution safe. And when you monitor your Windows Server 2022 solution pro-active with Azure Monitor, Azure Security Center, Azure Defender like this with Azure Arc enabled Servers
