Kubernetes Network Policies Procurement Ticket
No one wanted to touch it, but it was the blocker for production.
Kubernetes network policies control how pods talk to each other and to the outside world. Without them, every pod is wide open. Attackers can pivot across services. Sensitive workloads can be reached from less secure ones. The procurement ticket exists because even in a DevOps-driven world, implementing network restrictions is still a process—security review, requirements gathering, and approvals.
A complete procurement ticket for Kubernetes network policies should include:
- Namespace scope and target workloads
- Ingress rules detailing allowed sources and ports
- Egress rules for outbound connections and destinations
- Label selectors to match specific pods
- Policy type: ingress, egress, or both
- Compliance or audit references
- Testing and rollout plan
Link the ticket to your cluster inventory. Include YAML definitions for each proposed policy. This makes approval faster because reviewers see exactly what will be applied. Avoid vague descriptions; define every CIDR, port, and protocol.
In Kubernetes, network policy changes are not isolated. Misconfigurations can cut off critical service-to-service traffic. Always deploy to a staging namespace first. Log pod traffic before and after changes to validate the effect.
Procurement delays often come from unclear justifications. Tie each rule to a known security control or regulatory requirement. If you can map to NIST, ISO 27001, or PCI-DSS, do so in the ticket. Make the cost of inaction explicit.
Automate approvals where possible. GitOps workflows can route network policy YAML through code review and automated linting. At merge, policies can be applied without waiting for manual intervention.
A strong Kubernetes Network Policies Procurement Ticket shortens lead time, reduces friction, and closes attack surfaces. It is the difference between chaos and controlled communication in your cluster.
