- →Implement NetworkPolicies to control traffic flow to and from your pods.
- →Use CiliumNetworkPolicy for advanced Layer 3-7 security specifications.
Mastering Multi-Tenancy in Kubernetes: Security and Isolation Strategies
Multi-tenancy in Kubernetes is crucial for securing workloads in shared environments. Understanding how namespaces and RBAC work together can make or break your security posture. Dive in to learn the specifics that matter in production.
- →Utilize namespaces for isolating API resources within a cluster.
- →Implement RBAC to enforce strict authorization for users and workloads.
Implementing Istio Authorization Policies: Allowing HTTP Traffic with Precision
Securing your Istio mesh is critical for protecting workloads. This article breaks down how to set up an ALLOW action for HTTP traffic using Istio's AuthorizationPolicy. You'll learn how to incrementally grant access while maintaining a strong security posture.
- →Create a baseline security policy with an `allow-nothing` AuthorizationPolicy.
- →Gradually define ALLOW actions for specific workloads using the `spec.selector` and `spec.rules` fields.
Mastering Access Control for the Kubernetes API
Securing the Kubernetes API is critical for protecting your cluster. Understanding the multi-layered approach—transport security, authentication, and authorization—can save you from major security pitfalls. Dive into the specifics of how to configure these layers effectively.
- →Secure the API server by configuring it to listen on port 6443 with TLS.
- →Authenticate requests using various modules to ensure they come from valid users.
