Introduction to Microsoft Defender for Cloud
With Microsoft Defender for Cloud, security teams can easily monitor and manage security posture, identify vulnerabilities, and investigate security incidents. It provides unified visibility and control across hybrid environments, allowing security teams to easily manage security posture, and it integrates with other Microsoft security solutions, such as Azure Sentinel and Microsoft Cloud App Security, to provide a comprehensive security solution for cloud environments.
It uses advanced analytics and machine learning to detect and respond to threats across hybrid environments, including virtual machines, containers, databases, and serverless resources. It helps organizations to protect their cloud workloads and services from a wide range of security threats and provides the necessary visibility and control to manage security posture effectively.
What is Microsoft Defender for Cloud?
Microsoft Defender for Cloud is a cloud-native security solution that helps organizations protect their cloud workloads and applications across multiple cloud platforms, including Azure, AWS, and Google Cloud Platform. It provides advanced threat protection, vulnerability management, compliance management, identity and access management, threat intelligence, and security information and event management (SIEM) capabilities.
With this application, organizations can monitor and manage their cloud security posture from a single console, and respond to potential security threats in real-time. The solution uses artificial intelligence (AI) and machine learning (ML) to detect and block potential threats, and it continuously learns from security events and incidents to improve its threat detection and response capabilities over time.
What is a Secure Score?
As you must have known by now that Microsoft Defender for Cloud has two goals :
- It helps you understand your current security situation.
- It helps you improve your security situation by giving recommendations.
A secure score is a way to achieve your goal: the higher the score, the lower the risk level.
To improve the percentage, review Security center recommendations for the pending actions. Proposals also include steps to follow to achieve the goal.
How is the Secure Score Calculated?
Each recommendation has some points assigned to it. If you apply that recommendation, the score will automatically increase. Each proposal will have a maximum score and a current score, as shown in the figure.
Few formulas are used by azure to calculate the score, which you as a user don’t need to worry about. You need to follow the security recommendations provided by Microsoft Defender for Cloud

Security Alerts
Security alerts are notifications or warnings generated by security systems or software to indicate that a potential security threat or issue has been detected. These alerts are designed to alert security teams or administrators to take immediate action to investigate and respond to the potential threat.
Respond to a security alert
After you’ve investigated a security alert and understood its scope, you can respond to the alert from within the portal:

Take action:
The different steps one can take are:
- Mitigate the threat: Provide a manual solution for the alert.
- Prevent further attacks: Provide security recommendations to help reduce the attack.
- Trigger automated response: Provide an option of a logic app to trigger automatically.
- Suppress similar attacks: suppress if that alert is not relevant to your organization.
