The situation
What needs investigation
A pipeline may build and deploy quickly but have secrets in configuration, unscanned dependencies, broad deployment permissions, or weak artifact traceability. The review identifies controls that reduce risk without making every release depend on a manual security queue.
Signals we look for
Source
- dependency scanning
- secret detection
- branch protection
Artifact
- image scanning
- registry permissions
- artifact provenance
Deployment
- IAM roles
- approval conditions
- environment permissions
Audit
- pipeline logs
- change traceability
- exception handling
How we investigate
Each step is validated against the workload before the next change.
- 01
Map the pipeline
Record source, build, artifact, deployment, and promotion identities.
- 02
Find credential paths
Identify where secrets are stored, injected, rotated, and exposed.
- 03
Add actionable scans
Use dependency and image checks that create a clear response path.
- 04
Scope deployment roles
Separate build, deploy, and runtime permissions.
- 05
Protect promotion
Define approval and exception rules for higher-risk changes.
- 06
Review evidence
Ensure logs show what artifact and configuration reached each environment.

Exception processnot documented
Engineering interpretation
A scanner without a release decision or exception owner creates noise. The team needs a severity policy, a remediation path, and evidence of when a release was allowed to proceed.
Possible next investigation
- Define which findings block promotion.
- Set an exception approval and expiry path.
- Use trusted base-image update ownership.
- Record scan result with the release artifact.
Trade-offs we consider
Security depth
More scanning only helps when results are triaged and owned.
Release speed
Blocking controls must be limited to conditions that need a decision.
Permissions
Scoped roles reduce risk but require accurate pipeline design.
Auditability
Evidence must be retained without exposing secrets in logs.
