Tutorial / Cram Notes
Microsoft Defender for Cloud, formerly known as Azure Security Center and Azure Defender, is a comprehensive security management and threat protection service that provides advanced threat protection across hybrid cloud workloads running in Azure, on-premises, and in other cloud environments. With Defender for Cloud, organizations can strengthen their security posture, protect against cyber threats, and streamline security management without the need for extensive security expertise.
Key Features of Microsoft Defender for Cloud
- Unified Security Management: Defender for Cloud provides a centralized dashboard for monitoring the security health of resources across different environments. It evaluates the security state of your resources and suggests remediation actions to improve your security posture.
- Security Recommendations and Secure Score: The tool identifies potential security vulnerabilities and provides recommendations to mitigate these risks. Organizations can track their security posture over time with the secure score, which quantifies their security posture based on the implementation of recommended controls.
- Adaptive Application Controls: These are intelligent, automated firewall rules that help control which applications can run on the VMs in your environment, reducing the attack surface.
- Threat Protection: Microsoft Defender for Cloud detects and responds to threats targeting your Azure and non-Azure resources. It provides advanced threat detection capabilities, using analytics and threat intelligence to identify attacks.
- Compliance Management: Defender for Cloud assesses your environment against regulatory compliance standards and benchmarks such as Azure CIS, PCI DSS, ISO 27001, and more, providing detailed insights and recommendations to help meet compliance obligations.
- Just-In-Time VM Access: This feature provides controlled access to Virtual Machines, reducing exposure to attacks while providing convenient access to connect to VMs when needed.
Examples of Microsoft Defender for Cloud in Action
- Virtual Machine Protection: Defender for Cloud continuously assesses the VMs for vulnerabilities like unpatched operating systems or misconfigurations and provides actionable security recommendations. For instance, if a VM is found to be running an outdated operating system, Defender for Cloud alerts the administrator with a recommendation to update the operating system to mitigate potential vulnerabilities.
- Storage Account Security: Defender for Cloud checks the security configuration of Azure Storage accounts to ensure that they are not publicly accessible unless necessary and recommends enabling secure transfer for data in transit where it is not used.
- SQL Database Security: It monitors Azure SQL Database for potential SQL injection attacks and anomalous database access or query patterns, suggesting improvements, such as enabling Advanced Data Security for real-time threat detection.
- Network Security: Defender for Cloud evaluates network security configurations, such as Network Security Groups and Application Security Groups, and suggests changes to enforce a stricter security model, like the principle of least privilege.
- Regulatory Compliance: A company subject to PCI DSS for handling credit card data can use Defender for Cloud to gauge how well its Azure resources comply with these standards. It would provide insights into non-compliant resources along with guidance for addressing these gaps.
