The "interim state" is the period between signing an acquisition agreement and executing full systems integration. It is the most vulnerable phase of the infrastructure life cycle. Insecure site-to-site VPN tunnels are often established, bridging legacy target environments with modern corporate networks without fine-grained security policies.
Zero Trust Network Ingress
Instead of bridging network layers via VPC peering, we implement SPIRE/SPIFFE to enforce workload-to-workload identity verification. This bypasses static firewall rules and IP-based access sheets, ensuring that even if a legacy cluster is compromised, it cannot make arbitrary connections to corporate data layers.
Securing the Kubernetes API Server
- Enforcing mutual TLS (mTLS) for all service communications.
- Implementing OPA Gatekeeper policies to reject workloads without verified security contexts.
- Restricting access to the Kubernetes control plane using private API endpoints.
