Just-in-Time VM Access with Defender for Cloud in Azure

Unsecured management ports on virtual machines are primary targets for brute-force attacks and unauthorized entry. Learning how to restrict access dynamically is essential for protecting modern cloud workloads. This text-based course guides you through implementing Just-in-Time (JIT) virtual machine access to secure your cloud perimeter. You will learn how to configure policies that grant temporary, authorized access to critical VM ports only when needed, ensuring your infrastructure remains locked down by default. What you'll learn: - Understand the core principles of Just-in-Time (JIT) access and zero-trust cloud security architecture. - Configure JIT VM access rules within Defender for Cloud to protect management ports like RDP and SSH. - Request and approve temporary access to virtual machines through the Azure portal. - Monitor and audit JIT access logs to maintain compliance and visibility over your network. - Apply modern cloud security posture management best practices to reduce your overall attack surface. Starting with foundational security concepts and common threat vectors, this course walks you through the practical setup, policy configuration, and day-to-day management of JIT access rules. This course is designed for beginners, aspiring cloud administrators, and security enthusiasts, with no prior cloud security experience required.
