What is Defender for Cloud?

Defender for Cloud is a tool for security posture management and threat protection. It strengthens the security posture of cloud resources, through an integrated collection of Microsoft Defender plan, and it protects workloads running in Azure, hybrid, and other cloud platforms.


In this lecture, you are introduced to Microsoft Defender for Cloud, a tool that serves two primary functions: security posture management and threat protection. It is designed to reinforce the security posture of your cloud resources by integrating various Microsoft Defender plans. These plans provide robust defenses for your compute, data, and service layers across different environments, including Azure, hybrid workloads, and other cloud platforms such as Google Cloud Platform (GCP) and Amazon Web Services (AWS).

You learn that Defender for Cloud aids in resource hardening, security posture tracking, and protection against cyberattacks, simplifying security management through native integration. An important feature discussed is auto-provisioning, which secures your resources by default and enables continuous assessment of your environment for security improvements.

The lecture emphasizes the importance of the Secure Score, a metric that provides a quick overview of your current security situation, where a higher score indicates a lower risk level. The lecture explains how security recommendations, which come with prioritized hardening tasks, can improve this score. Additionally, there is a Fix button for some recommendations, offering automated remediation.

Defender for Cloud’s threat detection capabilities are also covered, with the provision of security alerts through the Azure portal or email notifications, and the ability to stream these alerts to SIEM (Security Information and Event Management), SOAR (Security Orchestration, Automation and Response), or IT Service Management solutions.

Finally, the lecture discusses the initial setup of Defender for Cloud, where it generates a Secure Score based on an assessment of your connected resources in alignment with the Azure Security Benchmark. The generated hardening recommendations are designed to address security misconfigurations and vulnerabilities.

As a student preparing for an exam, you are advised to remember the dual role of Microsoft Defender for Cloud in managing security posture and providing threat protection across various cloud environments, including hybrid scenarios. You should also focus on understanding the centrality of the Secure Score and how it serves as a quick reference to the security health of your environment.
