No. The article’s central point is that they share the same attack surface once containers depend on cloud identity, orchestration and storage. Separate programmes usually create blind spots in ownership, telemetry and escalation. A unified operating model gives practitioners one view of exposure and one response path.
Why container security and cloud security converge in practice
Containers do not create a separate security universe. The moment images are pulled from a registry, workloads assume cloud identities, and state is written to cloud storage, the relevant controls become shared. That means image hygiene, orchestration policy, access governance, telemetry, and incident response should be designed as one operating model rather than two disconnected programmes.
A useful way to frame the issue is that the container is only one execution layer in a wider cloud path. If the cloud side is weak, a “container-only” programme misses the identity, storage, and control-plane dependencies that determine whether a compromise can spread.
The same is true in the opposite direction. A cloud-only programme that treats containers as generic compute often misses image provenance, runtime drift, insecure base layers, and registry exposure. The result is duplicated tooling, inconsistent ownership, and gaps between teams that each believe the other one owns the risk.
One practical test is whether the same control decision affects both places. If a secret in an image can authenticate to a cloud service, or if an overpermissive workload identity can reach storage and metadata endpoints, then the control boundary is already shared. That is why NIST SP 800-190 Container Security and CSA Cloud Controls Matrix are most useful when read together, not as competing programme charters.
Where the boundary blurs: identities, registries, orchestration, and storage
Container risk usually enters through shared dependencies rather than the container abstraction itself. Registries, orchestration platforms, secret stores, cloud IAM, object storage, and logging backends all become part of the same trust chain. If one layer is reviewed in isolation, teams can miss how a benign configuration choice in one control plane creates exposure in another.
This is especially visible in access paths. A workload that can read a token, access a metadata service, or reach a storage bucket is operating within cloud identity and authorization rules, even if the operational symptom is “a container issue.” The same applies to image build pipelines and deployment automation, where credentials and tokens often determine what the runtime can do.
That is why programme separation tends to fail in the details. Security ownership becomes fragmented, alerts land in different queues, and escalation paths depend on which team first notices the issue. A unified view helps practitioners see the full chain from image build to runtime to data access, and it reduces the chance that one team closes a ticket while another still carries the exposure.
For teams needing a baseline on the container side, NIST SP 800-190 Container Security remains the clearest anchor for image, registry, orchestrator, and runtime concerns. For the cloud control plane, ISO/IEC 27001:2022 Information Security Management and ISO/IEC 27002:2022 Information Security Controls provide the broader governance and control structure for the shared environment.
What a unified programme should optimise for
A unified model should optimise for one ownership map, one telemetry model, and one incident path. The key question is not whether the work is “container” or “cloud,” but whether the team can answer who owns the control, where the signal is observed, and how blast radius is contained when a workload or its credentials are abused.
Practitioners should align controls around the object being protected, not around organisational silos. Image signing, registry policy, workload identity, storage permissions, runtime detection, and cloud logging need to be reviewed as a chain because compromise usually moves across those boundaries rather than staying inside one product category.
When teams keep the operating model unified, they can standardise policy enforcement and avoid duplicate review. That does not mean every control is identical in both layers. It means the same risk lens governs both layers, so a change to deployment, identity, or storage is assessed for downstream runtime impact before it reaches production.
For cloud control mapping, the CSA Cloud Controls Matrix is useful because it spans IAM, infrastructure, logging, and supply chain concerns in one structure. For the container-specific side of the operating model, NIST SP 800-190 Container Security helps keep the runtime and image lifecycle in view.
Risk and Threat Considerations
Splitting container security from cloud security usually increases risk, because attackers do not respect programme boundaries. They exploit the weakest link in the chain, such as leaked image secrets, overprivileged workload access, exposed registries, or permissive storage and metadata paths that let a compromise spread.
Failure mechanism: Separate teams often monitor different signals and own different remediation steps, so a compromise in one layer is not correlated with its effect in the other. That creates blind spots in detection, slow escalation, and inconsistent containment when a container inherits cloud permissions or secret material.
Impact: The likely result is wider blast radius, delayed response, and preventable data exposure. A single workload compromise can become cloud credential abuse, storage access, or lateral movement if the programme boundary hides the real trust boundary.

OWASP Non-Human Identity Top 10 addresses the attack and risk surface, while NIST SP 800-53 Rev 5, CIS Controls v8, NIST CSF 2.0 and CSA Cloud Controls Matrix set the governance and control requirements practitioners need to meet.

| NIST CSF 2.0 | GV.SC-01 — Cybersecurity Supply Chain Risk Management Strategy | Images, registries, and cloud dependencies form one supply chain and one trust path. |
| Recommendation — Apply one supply-chain risk strategy across image build, registry, orchestration, and cloud dependencies. | ||
| CSA Cloud Controls Matrix | IAM — Identity and Access Management | The question turns on cloud identity, access, and control-plane governance shared with containers. |
| Recommendation — Map container and cloud controls into one IAM governance model. | ||
| OWASP Non-Human Identity Top 10 | NHI-02 — Secret Leakage | Container images and workloads often expose credentials that bridge into cloud services. |
| Recommendation — Scan images and runtimes for leaked secrets and rotate any exposed credentials immediately. | ||
Practitioner Guidance
What to prioritise: Build the programme around shared assets and shared failure modes first, especially image provenance, workload identity, registry access, secret handling, storage permissions, and runtime telemetry. Those are the points where “container” and “cloud” are operationally the same problem.
What to verify: Confirm that one team can trace a workload from build to deploy to runtime to data access, and that incident response has a single escalation path for secrets, identities, and storage abuse. If those handoffs are split, the programme is already fragmented.
Practitioner takeaway: Treat container and cloud controls as separate implementation layers only, not separate security programmes; the risk lives in the shared control plane and the shared identity path.
