Microsoft Defender for Cloud

Introduction

• Microsoft Defender for Cloud, formerly known as Azure Security Center and Azure Defender, is a cloud-native application protection platform (CNAPP) that is made up of security measures and practices that are designed to protect cloud-based applications from various cyber threats and vulnerabilities.
• It offers unified security management and advanced threat protection across your hybrid cloud workloads.

• Defender for Cloud combines the capabilities of:
  • A development security operations (DevSecOps) solution that unifies security management at the code level across multicloud and multiple-pipeline environments
  • A cloud security posture management (CSPM) solution that surfaces actions that you can take to prevent breaches
  • A cloud workload protection platform (CWPP) with specific protections for servers, containers, storage, databases, and other workloads
