AKS security practices are crucial to protecting containerized applications on Azure Kubernetes Service (AKS). Implementing industry standards and best practices, such as limiting access to container operations, preventing root/privilege escalations, isolating Kubernetes nodes, using Kubernetes Role-Based Access Control (RBAC), avoiding sharing the host's IPC or network namespace, making sure to isolate Kubernetes nodes from public networks, using a read-only file system for containers, boosting authentication and authorization, disabling NET_RAW, double checking unsafe /proc mount, not keeping secrets in environment variables, and developing a rolling update strategy can help secure AKS clusters. Additionally, leveraging built-in security features in AKS, such as Azure Policy add-on for OPA Gatekeeper, network security policies, master security, and using expert tools like CAST AI's Kubernetes Security feature can also enhance security posture. By following these practices, teams can gain confidence in their cluster's security and protect against emerging threats.
