The Google Kubernetes Engine Security mind map template provides a structured framework for securing containerized workloads on GCP, covering 91 distinct security checkpoints across 9 major domains. This Google Kubernetes Engine Security cheat sheet is designed for cloud architects and DevSecOps engineers to audit cluster configurations, specifically focusing on the implementation of Private clusters and robust Authentication/Authorization protocols. The guide details critical infrastructure requirements, such as the use of 'Master Authorized Networks' to restrict control plane access and the configuration of 'Workload Identities' to manage pod-level permissions. By mapping out the relationship between VPC subnets and IP Address Ranges, this Xmind template ensures that network isolation and resource allocation follow Google Cloud's best practices for production-grade environments.

ã¹ããã 1
Import the Xmind file
Open the .xmind file in Xmind desktop or web to view the full 91-node security hierarchy.
ã¹ããã 2
Audit your configuration
Navigate through the 'Network' and 'Control Plane' branches to compare the template's best practices against your current GKE settings.
ã¹ããã 3
Customize security nodes
Add your own internal IP ranges to the 'IP Address Range' section and document specific RBAC roles in the 'Authentication' branch.
ãããã質å
This template includes a comprehensive breakdown of 9 key security areas: Private clusters, RBAC authentication, Node OS hardening, Network policies, Workload identities, Control Plane management, Master Authorized Networks, and detailed IP Address Range planning for VPC subnets.
Use the 'Node' and 'Network' branches as a checklist to verify that firewall rules are locked down, automatic upgrades are enabled, and that 'Network policies' are active to limit pod-to-pod communication based on labels.
Yes, this is a fully editable Xmind file. You can customize the 'Workloads' and 'Authentication/Authorization' nodes to match your specific organizational IAM roles and namespace-level RBAC requirements.
It is used to whitelist specific private (RFC1918) or public IP ranges that are permitted to communicate with the Kubernetes cluster's control plane, effectively blocking unauthorized external access.
