2026 Cloud Ecosystem Security Checklist — For Platform Teams and CTOs

2026 Cloud Ecosystem Security Checklist — For Platform Teams and CTOs

Hook: Security teams are stretched thin. This checklist distills 2026 must-haves into an actionable roadmap: the controls you should prioritize this quarter to reduce risk quickly.

Top-line controls

• Artifact signing and SBOM enforcement for all deployable packages (Secure Module Registry).
• Short-lived, scoped tokens and automated rotation with ratcheting privileges (Authorization Incident Response).
• Per-request cost and provenance tagging (observability playbook: Observability for Media Pipelines).
• Cache consistency and signed invalidations for edge caches (Edge Caching Evolution).

Implementation priorities (30/60/90)

1. 30 days: enable signing in CI, set short-lived tokens, and run a dependency audit.
2. 60 days: deploy a scoped internal registry and integrate SBOM checks into deploy gates.
3. 90 days: implement per-request cost attribution and begin cost-aware alerts.

Complementary measures

Managed layers like Mongoose.Cloud are useful for velocity but must be folded into identity and audit plans — ensure service tokens and telemetry are surfaced (Introducing Mongoose.Cloud).

Playbooks and training

Run incident response drills for auth compromises, integrate registry compromise scenarios, and do tabletop exercises that involve edge failure modes. See the incident response playbook for robust runbooks (Authorization Incident Response).

“Security is most effective when it’s baked into delivery pipelines and user experiences.”

Final checklist

• Sign everything: artifacts, container images and packages.
• Audit dependencies and enforce upgrades on critical CVEs.
• Short-lived credentials and automated rotations.
• Edge cache invalidation with signed messages.
• Per-request cost tracking tied to product owners.
