TL;DR: Container risk now spans build pipelines, orchestration, runtime, and the cloud IAM layer beneath them, according to Intruder. The operational lesson is that image scanning alone cannot govern containerised systems when credentials, RBAC, and misconfiguration create attack paths beyond the container boundary.
NHIMG editorial — based on content published by Intruder: analysis of container security across the full lifecycle
By the numbers:
- Intruder says 43% of cloud environments were affected by the Nginx Ingress Controller vulnerability set, with over 6,500 clusters publicly exposed.
Questions worth separating out
Q: How should organisations govern container security across build and runtime?
A: They should treat container security as a lifecycle, not a point-in-time scan.
Q: Why do containers often create hidden identity risk?
A: Containers multiply identities because each workload, registry, secret, and automation path can carry its own permissions.
Q: What breaks when container security stops at image scanning?
A: You miss the risks that emerge after the image is approved.
Practitioner guidance
- Implement continuous runtime verification for containers Do not rely on build-time scans alone.
- Review Kubernetes RBAC and cloud IAM as one control plane Map service accounts, roles, and attached cloud permissions together so you can see where a workload can move after compromise.
- Protect build pipelines and registries as identity systems Harden CI/CD credentials, enforce provenance checks, and restrict who can publish images or extensions.

Intruder's full article covers the operational detail this post intentionally leaves for the source:
- A fuller breakdown of the container attack lifecycle from build time through runtime
- The specific breach examples and vulnerability families that shape the current threat picture
- Practical examples of Kubernetes and cloud configuration checks that reduce exposure
- Intruder's prioritisation logic for assessing what is actually exploitable in container estates

Container security fails when teams treat the image as the boundary. The article shows that the real attack surface includes build systems, orchestration policy, runtime behaviour, and the cloud IAM layer underneath. That means container governance is really about controlling trust across the full delivery chain, not just scanning artifacts before release. Practitioners should manage container security as a lifecycle control problem, not a one-time hygiene task.
A question worth separating out:
Q: Who is accountable when a container compromise becomes a cloud incident?
A: Accountability should sit with the teams that own the full control chain, not just the workload. Security, platform, and development teams each hold part of the evidence needed to prevent escalation. Organisations should define who approves images, who manages cluster policy, who owns secrets, and who can revoke access when a container crosses its intended trust boundary.
