Microsoft Azure Security Center is a platform for complete security administration throughout hybrid cloud systems. It is created to address data loss arising 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.
Pricing
Azure Security Center has a free tier for all its services. It also integrates with Azure Defender to safeguard Azure, on-premises, and hybrid systems. Continuous assessment and security recommendations, as well as Azure Secure Score, are included in the free tier of Azure Security Center.
Unless you were specifically opt-out, Azure Defender will register and begin safeguarding all of your assets once you activate it.
For the first 30 days, Azure Defender is free. Any usage that lasts longer than 30 days will be directly billed according to the pricing system.
There is also the standard tier. The standard tier expands the free tier’s functionality to workloads operating in private and public clouds. The standard tier also provides enhanced threat detection performance.
- Servers are protected by Azure Defender at a cost of $0.02/server/hour and 500 MB of data per day is included.
- The price of Azure Defender is $0.02 per hour per App Service.
- Almost any resource charge is in the range between $0.02 and $15
Azure Security Center Features
The following are some features of Azure Security Center:
- It provides centralized security management for various types of clouds including Azure and non-Azure clouds.
- Azure applications, networks, servers, and virtual machines are all protected against threats.
- Application restrictions are flexible and automatic.
- Centralized security policies management is required to conform with corporate rules and legal requirements.
- Consideration of security suggestions and warnings so that the most important issues may be addressed right away.
- Machines, networking, memory, and communication services, as well as applications that run throughout businesses’ environments, are all subject to ongoing security assessments.
Next, we are going to discuss the architecture of Azure Security Center.
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, you can always consult the official Azure security documentation.

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 and offers suggestions and threat alarms for workload protection.
Therefore, Azure Security Center aids in the 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 Azure PowerShell cmdlets to query data, integrate with an existing security information and event management (SIEM) solution, such as Azure Sentinel, or leverage REST APIs.
Advantages
Now that you have understood what Azure Security Center is and how it is used, let us discuss some of its advantages that make it a better choice for security standards.
- Utilizing in-built first-party or third-party security mechanisms to reduce expenses and reallocate resources.
- Agent installation for on-premises server workloads is simple.
- Threat protection prioritizes most serious threats.
- By effectively controlling security rules throughout hybrid workloads and assets, compliance with internal and external regulatory security standards can be assured.
- Security flaws can be addressed before they are identified and attacked by hacks by prioritizing and implementing security recommendations.
- Security information can be gathered from a number of sources, including linked partner solutions, to collect, explore, and analyze.
Best Practices
The following are a few procedures that will help you use Azure Security in the most effective way:
- Activate disk encryption monitoring for Microsoft Azure VMs.
- Allow endpoint security tracking and suggestions for Microsoft Azure VMs.
- Make sure that Azure Security Center is used to detect outside users with write access.
- In the settings of Azure Security Center, make sure that one or more security contacts’ email accounts are configured.
- Allow OS security detection for Microsoft Azure VMs.
- Make sure that your Azure with IP routing is being tracked.
- Make sure that your Microsoft Azure User’s Security Center basic price tier is activated.
- Make sure that updates to Azure cloud security policies are identified in your Microsoft Azure cloud account.
- Make sure that Azure VMs have next-generation firewall tracking activated.
Conclusion
One of the most valuable features of a cloud service like Azure Security Center is the capability to see the broad picture and be a part of a collaborative defense against malicious attackers. Microsoft leverages its large collection of data and knowledge about security across all services and clients when a company uses Azure Security Center.
To sum up, Azure, using machine learning, analyzes data warehouses for existing and upcoming risks so as to get timely protective recommendations.
