Background for this topic.
Azure is a cloud platform offering computing, storage, and networking services that organizations use to run applications and manage data. Security in Azure depends on a shared responsibility model: Microsoft protects the physical infrastructure and core services, while users must secure their configurations, identities, and data within the environment.
Key security concerns include misconfigured access controls that expose resources, vulnerabilities in deployed applications or services, and risks from exposed management endpoints. Effective security requires enforcing least privilege through identity and access management, segmenting networks to limit lateral movement, and continuously monitoring for suspicious activity. Regular patching of workloads and careful configuration of Azure-native security features are critical to reducing attack surfaces and preventing unauthorized access or data exposure.
