Project
Policy-as-code factory
Audit-ready- Enforced OPA and Sentinel policy checks on every Terraform plan.
- Applied least-privilege IAM defaults across provisioned environments.
- Centralized CloudTrail audit logging for infrastructure changes.
Why this project is valuable
Strong policy-as-code signal
This project shows automated governance enforcement instead of manual security reviews or ad hoc IAM cleanup.
Clear compliance value
Policy-checked provisioning is easy for recruiters to understand because it maps to audit readiness, least privilege, and controlled infrastructure changes.
Good ATS coverage
The project naturally supports OPA, Sentinel, IAM, least privilege, policy-as-code, and audit logging keywords.
Good interview depth
You can discuss policy design, plan validation, IAM least privilege, CloudTrail integration, and how you blocked non-compliant infrastructure.
Project overview
A policy-as-code environment factory is strong DevSecOps resume material because it shows how you made infrastructure provisioning auditable and security-enforced instead of relying on manual review.
The factory provisions cloud environments through reusable Terraform modules, but every plan passes OPA and Sentinel policy checks that validate IAM permissions, network exposure, encryption settings, and tagging requirements before apply.
That gives you concrete ways to describe policy-as-code, least-privilege IAM, CloudTrail audit logging, and the practical benefit of blocking over-permissioned or non-compliant infrastructure before it reaches shared environments.
Architecture overview
Project flowEnvironment request
Teams request a new environment through a standardized provisioning workflow with required security metadata.
Terraform module layer
Reusable modules define networking, IAM, compute, and supporting resources with least-privilege defaults.
OPA policy evaluation
OPA evaluates Terraform plans against security policies for IAM scope, encryption, and network exposure.
Sentinel compliance checks
Sentinel enforces organizational compliance rules and blocks plans that violate mandated security controls.
Least-privilege IAM provisioning
IAM roles and policies are created with scoped permissions instead of broad administrative access.
Audit logging handoff
CloudTrail captures all infrastructure changes with traceable, reviewable audit records for compliance teams.
What this project includes
- OPA and Sentinel policy checks on every Terraform plan
- Least-privilege IAM defaults for provisioned environments
- CloudTrail audit logging for infrastructure change traceability
- Reusable Terraform modules with security-enforced defaults
- Blocked non-compliant plans before apply to shared environments
Tech stack
This stack is practical for DevSecOps hiring because it shows how policy-as-code and audit logging make infrastructure provisioning governable and auditable.
Terraform
Defines reusable infrastructure modules and makes environment setup repeatable and reviewable.
OPA
Evaluates Terraform plans and Kubernetes manifests against codified security policies before changes are applied.
Sentinel
Enforces organizational compliance rules and blocks infrastructure plans that violate mandated controls.
IAM
Implements least-privilege access patterns with scoped roles instead of broad administrative permissions.
CloudTrail
Provides audit logging for all infrastructure API calls and change events across provisioned environments.
GitHub Actions
Runs plan validation, policy evaluation, and audit-friendly approval workflows before infrastructure apply.
Features implemented
Policy-as-code enforcement
Security policies are version-controlled and automatically evaluated on every infrastructure change.
Least-privilege IAM defaults
New environments start with scoped permissions instead of over-permissioned administrative roles.
Plan validation gates
Non-compliant Terraform plans are blocked before they affect shared environments.
Audit-ready provisioning
CloudTrail logging makes every infrastructure change traceable for compliance and incident review.
Reusable secure modules
Teams provision environments from security-enforced patterns instead of rewriting cloud setup each time.
Compliance automation
Sentinel and OPA replace manual security review with repeatable, auditable policy checks.
Resume bullet examples
These bullets show how to present infrastructure-as-code work as policy enforcement and governance value instead of generic Terraform usage.
- Built a Terraform environment factory with OPA and Sentinel policy checks that blocked over-permissioned IAM roles and non-compliant infrastructure plans.
- Enforced least-privilege IAM defaults and CloudTrail audit logging so new environments started with auditable, security-controlled access patterns.
- Added plan validation gates in CI that caught open security groups, missing encryption, and policy violations before infrastructure apply.
- Reduced manual security review by codifying infrastructure compliance rules into repeatable OPA and Sentinel policy evaluations.

ATS keywords extracted from this project
Use keywords that reflect policy enforcement and auditable provisioning, not only the word Terraform.
Interview questions based on this project
Policy-as-code factory projects often lead to questions about governance design, IAM least privilege, and how you blocked non-compliant infrastructure.
What made this more than writing Terraform once?
The project focused on OPA and Sentinel policy enforcement, least-privilege IAM defaults, CloudTrail audit logging, and blocking non-compliant plans before apply.
How did OPA and Sentinel work together?
OPA evaluated plan content against security policies while Sentinel enforced organizational compliance rules — together they provided layered governance before infrastructure changes.
Why was least-privilege IAM part of the story?
Because secure environment creation depends on scoped access from the start, not broad permissions that get tightened later during an audit.
How would you improve it further?
I would add drift detection against policy baselines, automated IAM access reviews, cost-aware security policies, and richer compliance reporting dashboards.
Common mistakes
Explain the policy-as-code enforcement, least-privilege IAM, and audit logging impact that made the infrastructure work security-focused.
IaC security projects are stronger when they show what gets blocked by OPA or Sentinel, not just what gets provisioned.
CloudTrail and audit trails help the project feel more realistic and compliance-minded.
Recruiters should understand how the factory improved audit readiness, access control, or compliance posture for engineering teams.
FAQ
Is a policy-as-code environment factory a good DevSecOps resume project?
Yes. It clearly demonstrates OPA, Sentinel, least-privilege IAM, audit logging, and practical infrastructure governance in a realistic system.
Does this help for cloud security or compliance roles?
Yes. It maps well to DevSecOps, cloud security engineering, and compliance automation roles because it shows policy-enforced provisioning workflows.
Should I mention OPA and Sentinel on my resume?
Yes, if they genuinely shaped the provisioning workflow and you can explain what policies they enforced and what violations they blocked.
How many bullets should I use for this project on a resume?
Usually two to four bullets are enough. Focus on policy enforcement, least-privilege IAM, and the governance improvements the factory created.
