The Architecture of Azure Security Center
The next important aspect of understanding the Microsoft Azure Security Center is the Azure security center architecture. Understanding the architecture could help us in evaluating how it works for ensuring the security of cloud workloads. Security Center is a native component of Azure. So, the security center provides monitoring and protection for PaaS services on Azure such as SQL databases, storage accounts, and Service Fabric without the need for any deployment.
The security center also provides safeguards for non-Azure servers and virtual machines on-premises or in the cloud. Azure Security Center ensures protection for both Windows and Linux server environments through the installation of Log Analytics agent on them. Most important of all, the security center also ensures the auto-provisioning of Azure virtual machines.
The next important highlight in Azure security center architecture is the security analytics engine. Readers should note that the security analytics engine helps in correlating the events collected from Azure and from the agents. Based on the results of correlation, the security analytics engine provides reliable recommendations for strengthening the security systems.
For example, you can get recommendations for ensuring the security status of workloads or create customized security alerts. The alerts by the security analytics engine should be the foremost priority of security administrators. Quick and proactive investigation of security alerts can help in preventing any malicious attacks on your workloads.
The Azure security center architecture also depends on the in-built security policy of the security center. You can find it as an in-built initiative in Azure Policy under the Security Center category upon enabling the security center. The in-built initiative is assigned automatically to all registered Security Center subscriptions.
It is essential to note that this in-built initiative in Azure security center architecture comprises of Audit policies only. However, you don’t have to worry about leveraging the maximum potential of Microsoft Azure Security Center. You can always try the official Azure security documentation to excavate additional information about security center policies.
How Does Azure Security Center Work?
Now that you have reflected on the architecture of Azure security center it is important to know how it works. Upon activating the security center, you will have an automatic deployment of a monitoring agent to Azure virtual machines. In the case of on-premise virtual machines, you have to deploy the monitoring agent manually.
Then the security center starts assessment of security status in all your virtual machines, applications, data and networks. Reflecting upon any Azure security center tutorial in detail, you can find that the analytics engine helps in data analysis. Subsequently, machine learning helps in data synthesis and providing recommendations and threat alerts for safeguarding workloads.
Therefore, Azure security center helps in faster identification of any threat or anomalous activity. Users can aggregate their security information in Azure Monitor workspace to ensure big data querying capabilities. In addition, users can also choose for querying through PowerShell cmdlets, integration with an existing SIEM (Security Information and Event Management) tool such as Azure Sentinel or REST APIs.
Advantages of Azure Security Center
The next important concern about Microsoft Azure Security Center refers to its applications. Here are some of the notable advantages that you can get by adopting Azure security center.
- Extending the scope of security status management and threat protection for on-premises virtual machines (VMs).
- Easy provisioning of an agent to on-premises server workloads.
- Assessment of security through the facility of a unified view of various hybrid cloud workloads.
- Connection with existing tools and processes such as security information and event management (SIEM) or integration of partner security solutions.
