Introduction to Microsoft Azure Security Center

Azure Security Center is a collective infrastructure that promotes the security management aspect within the Azure service space. The main role of the Azure Security Center is to add strength to the entire security posture of the Azure datacenters. Along with that, it ensures proficient threat protection for the hybrid workloads within the cloud. It does not matter whether you are within the Azure cloud or not; Azure Security Center has the potential to offer you threat management for all types of hybrid workloads within different clouds.

Azure Security Center is best at keeping the important resources safe. It is termed to be a collective effort implemented by Azure, cloud provider, and you. Before you can implement the workloads and move them to the cloud, you need to take concern for their secure existence. And, Azure Security Manager offers you the feasibility of securing the workloads. Azure Security Center equips you with the necessary tools that intend to harden the network, secure the services and streamline the security aspects of it for seamless execution.

So, if you are in a conflict about whether to trust Azure Security Center or not, then this article intends to help you out with the core fundamentals and concepts within it. Follow this article till the end to ensure that you master all of the concepts and knowledge associated with Microsoft Azure Security Center.

Brief Overview of Microsoft Azure Security Center

Microsoft is actively integrating several physical, operational, and infrastructure controls to help secure the Azure cloud services. Apart from that, it would be best to take utmost security concerns for a few of the additional actions. Azure Security Center has the potential to safeguard the workloads right from the moment you enable it! It will strengthen the cloud security aspects of the infrastructure. Therefore, Azure Security Center intends to offer you protection against all types of hybrid workloads within Azure or other clouds.

Azure Security Center makes use of Azure Defender to offer such high-level security to the cloud infrastructure. It assesses and visualizes the state of security for all of the Azure resources. Moreover, it has the potential to simplify enterprise security compliance and monitor it against all of the regulatory requirements. The best part is that the Azure Security Center makes use of AI and automation for putting up an exception for turning down all the false alarming situations. Following that, it intends to identify the threats as quickly as possible for streamlining the threat investigation and recovery.

With Azure Security Center, you can assess all the cloud resources, storage, applications, networks, workloads, and SQL. When you get an idea about the security state of all these resources, you can intend to work upon enhancing their potential. Moreover, if you wish to monitor the state of security and secure-posture of the cloud infrastructure, then you can use Azure Secure Score for the same. Microsoft Azure Security Center allows you to commence with easy deployment on large-scale environments by integrating the use of automation and policies. With Azure Security Center, you can streamline the pathway for threat investigation, and the remediation process can be automated as well.

Security Challenges Attended By Azure Security Center

Azure Security Center can be well understood by getting insight into the right potential of how it attends to the major security challenges. There are three security challenges that are of utmost concern, and Azure Security Center has the potential to attend and sort them out. The challenges include:

  1. Workloads Tend to Change Rapidly

Rapid changing workloads are considerably a strength to cloud operations but are also a progressive challenge that the security concerns need to attend to on priority. The end-users also intend to implement more of their measures to tweak the workloads. Apart from that, you need to be sure of the fact that all of the ever-changing cloud services used by people meet the security standards. Azure Security Center intends to offer you ideal protection to ensure the security of those practices, even though the workloads change frequently. 

  1. Lack of Security Skills

The administrators within the organizational space are responsible for protecting the cloud environment that is carrying out your services. The biggest challenges for the organizations operating within the cloud are to stay updated with the new possible attacks. It is quite impossible to stick to just one security front when the demands are ever-changing within the organizational space. Therefore, along with the security administrators, it is important for you to take the assistance of Azure Security Center

  1. Rapid Increase in Impactful Attacks 

It doesn’t matter where you run the workloads; the attacks are worsening over time and are accountable to be more sophisticated. And to take a step towards staying prepared for such attacks, it is important that you intend to secure the public cloud workloads. Make sure that those public workloads are in effect. Most of the internet workloads that are not embedded with the security practices are possibly more vulnerable to such attacks. Therefore, implementing the Azure Security Center is ideal for this purpose. 

Azure Security Center has the potential to help you protect against all of these challenges with the right availability of tools and solutions. The tools within Azure Security Center intend to help you come up with efficacies such as:

  1. It allows you to strengthen the security posture of your entire cloud infrastructure. It assesses the environment upon which your business operates and will enable you to get insight into the resource status, to know whether they are secure or not. 
  2. It will help you get complete protection against some of the major threats by assessing the workloads. Following that, it will trigger the threat prevention alerts and recommendations. 
  3. Faster security is yet another potential of Azure Security Center, as everything within this initiative is done with respect to cloud speed. Azure Security Center is a native integration, and the deployment of it is quite easy. Therefore, it offers you protection and auto-provisioning with the respective Azure services.

The Use of Azure Defender within the Security Center

Azure Defender is the dashboard or tool that is embedded within the Security Center in order to offer control and visibility of all the CWP features within the environment. The features of Azure Security Center intend to cover the two massive pillars of cloud security, which include Cloud Security Posture Management (CSPM) and Cloud Workload Protection (CWP).

Azure Defender within the security Center offers threat protection and security alerts for VMs, containers, web apps, networks, SQL databases, and more. You need to enable Azure Defender from the ‘Pricing and Settings’ tab over the Azure Security Center. There are specific Defender plans that are embedded within the Azure Security Center. Different plans have the different potential of offering comprehensive defenses for computing, service, and data layers within the environment.

With Azure Defender, you can secure the servers, app service, SQL, Kubernetes, storage, Key Vault, Container Registries, Resource Manager, DNS, and Open-source Relational Databases. Refer to this documentation to understand how Azure Security Center and Defender offer security to these resources. There is a separate product as Azure Defender for IoT that has a different significance. Follow this documentation to know more about how this product is implemented.
