Microsoft Azure Arc Servers On-Premises and Azure Cloud Services

Earlier I wrote a blogpost about Microsoft Azure Arc services installation to manage on-premises Servers with Azure Cloud Services, like Azure Monitor and Azure Security Centre from the Cloud.
Here in this post you will see the Newest Microsoft Azure Cloud Services to Manage and Monitor your Servers on-premises with security and compliance included.

Azure Arc Extensions settings of the Server.

Here you can see we have installed the Microsoft Monitoring Agent for Azure Monitor and log analytics, second we have installed the dependency Agent for Windows for
insights, Performance and Service maps. Here you find more information about Virtual machine extension management with Azure Arc for servers (preview)  

After initial deployment of the Azure Arc for servers (preview) Connected Machine agent for Windows or Linux, you may need to reconfigure the agent, upgrade it, or remove it from the computer if it has reached the retirement stage in its lifecycle. You can easily manage these routine maintenance tasks manually or through automation, which reduces both operational error and expenses.

Managing and maintaining the Connected Machine agent

Azure Arc Insights Performance monitor

The Azure Arc Insights Performance monitor is there by default and installed with the following dashboards :

  • CPU Utilization
  • Available Memory
  • Logical disk IOPS
  • Logical disk MB/s
  • Logical disk Latency
  • Max logical disk used %
  • Bytes Sent Rate
  • Bytes Received Rate

Azure Arc Logs Analytics

Of course you can make your own custom Dashboards in the Azure Portal with your own triggers, so in this way you get the same Azure Monitor Innovative Tools for your On-Premises Servers. 😉

Within Microsoft Azure Arc Insights, you can also see a Service Map of the Server

Here is were the dependency agent comes in, you get a service map of the Server and see the communication lines with other resources. In this picture you see Server Yoda01 a Domain Controller of my MVPLAB.
You can see that there are three Clients are logged on the domain controller.

Microsoft Azure Security Center for Azure Arc Servers

 

One of the most powerful and important features of Microsoft Azure Cloud platform is Security! Microsoft Azure Security Center (ASC) is a unified infrastructure security management system that strengthens the security posture of your data centers, and provides advanced threat protection across your hybrid workloads in the cloud – whether they’re in Azure or not – as well as on premises.

Here you see my Azure Arc Servers (On-Premises) in Azure Security Center.

Azure Arc Server in Azure Security Center recommendations Summary

Five security assessments passed the test, but Azure Security assessment has two recommendations one is Medium Risk and one low.

Here you see the Security advise and the Remediation to take action on your Server.

Microsoft Azure Security Center Overview with the Overall Secure Score.

Security controls – Each control is a logical group of related security recommendations, and reflects your vulnerable attack surfaces. A control is a set of security recommendations, with instructions that help you implement those recommendations. Your score only improves when you remediate all of the recommendations for a single resource within a control.

To immediately see how well your organization is securing each individual attack surface, review the scores for each security control.

 Here you find More information about Azure Security Center Secure Score

To get your Azure Arc Servers (On-premises) complaint for the business and security, you can use Microsoft Azure Arc Policies

Azure Arc Policies to meet your Compliance state.

Conclusion

Microsoft is bringing Azure Cloud Power tools everywhere with Azure Arc Services to give you modern tools like Azure Monitor and Azure Security Center to keep you in control, Secure and Compliant for your business. Keep following Microsoft for Hybrid IT Management, because more awesome features are added every day in Microsoft Azure Cloud Services. Let’s start to get your Azure Security Score UP and UP 😉

Microsoft Azure Secure Score Dashboard

Microsoft Azure Security Center is working with Overall Secure Score. In my Test LAB we have some work to do 😉
The Azure secure score reviews your security recommendations and prioritizes them for you, so you know which recommendations to perform first. This helps you find the most serious security vulnerabilities so you can prioritize investigation. Secure score is a tool that helps you assess your workload security posture.
