Policy as Code: Transforming Governance in the Cloud Era

Introduction to Policy as Code

  • Definition: Automating policy creation and enforcement.
  • Importance in cloud-native and DevOps practices.
What is PaC

What is Policy as Code (PaC)?

  • Machine-readable definitions of policies and rules
  • Used to automate compliance checks and security enforcement
  • Written in human-readable formats (YAML, JSON, Rego, etc.)

Why Policy as Code?

  • Speed: Speed and scalability of cloud computing.
  • Collaboration: Devs and security teams use the same language/source of truth
  • Consistency: Reducing human errors and inconsistencies.

Core Concepts and Terminology

  • Policy: Rules that govern resource use.
  • Code: Policies defined in code files.
  • Idempotence: Ensuring repeated executions produce the same result.
  • Immutability: Unchanging over time.

Tools and Technologies

  • Open Policy Agent (OPA): General-purpose policy engine
  • HashiCorp Sentinel: Policy language integrated with Terraform
  • Other Options: Checkov, InSpec, etc.

Workflow & Implementation

  • Policy Creation: Collaborative process
  • Version Control: Git for tracking and changes
  • CI/CD Integration: Automate checks in pipelines

Demo: Writing and Testing Policies

  • Examples of policy code (e.g., deny public S3 buckets).

  • Testing tools and frameworks.

    package example
    default allow = false
    allow {
        input.user == "alice"
