Updated on 10th Sep, 22 197 Views

Microsoft Azure Security Center is a platform for complete security administration throughout hybrid cloud systems. It is created to address the issue of data loss that arises when a company moves to the cloud. Azure Security Center provides security to the resources present in your data center. Here’s a quick rundown of the topics that are going to be discussed in this blog.

Let us start this blog with a quick introduction to what is Azure Security Center.

Introduction

Azure Security Center can be defined as an overall security management system that provides security to the data centers. It not only offers security to Azure users but also secures other clouds. It also defends threats that can cause vulnerability to data centers.

When switching to an IaaS solution, you must protect your network infrastructure and services migrating to the cloud in a different way, as you take accountability for procedures that were previously handled by your cloud provider in a SaaS or PaaS environment.

The following are the most critical security issues tackled by Azure Security Center:

  • Constantly shifting workloads: Security Center analyzes your surroundings and helps you determine the condition of your resources and whether or not they are secured.
  • Threats that are becoming more complex: Security Center solves this issue by evaluating your workloads and generating threat avoidance suggestions and security warnings.
  • Skills in the field of security are in limited supply: The lack of qualified professionals in the field of security is an ongoing issue, but that can be easily solved with Azure Security Center because it is fully embedded and is simple to set up and operate. It also provides auto-provisioning and security for Azure services.

Architecture

The comprehension of Security Center’s architecture is essential to understand Azure Security Center. The architecture may aid in analyzing how Security Center functions in terms of cloud workload security. Azure Security Center is a built-in feature. As a result, it monitors and protects Azure PaaS services, including database systems, storage accounts, and Azure service fabric, without requiring any deployments.

Non-Azure servers and VMs on-premises or in the cloud are likewise protected by Azure Security Center. By installing the Log Analytics agent on both Windows and Linux server environments, Azure Security Center guarantees that they are protected. Most importantly, it guarantees that Azure VMs are provisioned automatically.

The security analytics engine is the next major feature of Azure Security Center’s architecture. The security analytics engine aids in the correlation of events acquired from Azure and the agents, which should be noted by the readers. The security analytics engine generates accurate suggestions for improving security systems depending on the correlation outcomes.

You may, for example, obtain advice for maintaining workload security or generate personalized security warnings. The security analytics engine’s warnings should be the top focus for security administrators. Security warnings should be investigated quickly and proactively to help avoid unwanted assaults on workloads.

The architecture is also influenced by Azure’s built-in security policy. When Azure Security Center is enabled, it appears as an in-built initiative in Azure Policy under the Security Center category. All authorized Security Center memberships are immediately allocated the built-in activity.

Moreover, If you need more information regarding Security Center policies, then you can always consult the official Azure security documentation.

Moving on, let us take a look at how to use Azure Security Center in the following section.

How to use Azure Security Center?

Now that we have talked about the architecture of Azure Security Center, it is time to learn how to use Azure Security Center. When you turn on Security Center, a monitoring agent is automatically deployed to Azure VMs. In the case of on-premise virtual computers, the monitoring agent has to be manually installed.

Azure Security Center then begins assessing the security of all of your VMs, apps, data, and networks. When you take a close look at any Azure Security Center lesson, you will see that the analytics engine assists with data analysis. As a result, machine learning assists in data synthesis as well as offering suggestions and threat alarms for workload protection.

Therefore, Azure Security Center aids in quick detection of any danger or unusual behavior. To assure big data querying capabilities, you may combine their sensitive data in Azure Monitor. You may also utilize PowerShell cmdlets to query data, integrate with an existing security information and event management (SIEM) solution, such as Azure Sentinel, or leverage REST APIs.
