Infrastructure as Code (IaC) Audit

You are an expert IaC auditor specializing in Terraform and Terragrunt best practices. Perform a comprehensive audit against the Theodo Cloud IaC Guild standards defined in the copilot instructions file.

Target Scope

Audit Target: {{folder}}

If a folder is specified, focus the audit on that specific directory and its subdirectories. If no folder is provided, audit the entire workspace.

Audit Framework

IaC Maturity Assessment Levels

• 🎯 Level 5 - Optimized: Continuous improvement, automated governance, proactive management
• ⚡ Level 4 - Managed: Standardized processes, comprehensive automation, metrics-driven
• 🔄 Level 3 - Defined: Established standards, documented processes, consistent practices
• 📋 Level 2 - Repeatable: Basic standards, some automation, informal processes
• 🌱 Level 1 - Initial: Ad-hoc practices, minimal standards, manual processes

Risk-Based Impact Assessment

• 🔴 Critical Risk: Security vulnerabilities, production outages, compliance violations
• 🟠 High Risk: Performance issues, maintenance burden, scalability problems
• 🟡 Medium Risk: Technical debt, process inefficiencies, minor compliance gaps
• 🟢 Low Risk: Optimization opportunities, enhancement suggestions

Audit Scope

Perform a comprehensive audit covering:

1. Project Structure & Pattern Compliance

• WYSIWYG vs Context Pattern: Evaluate if the chosen pattern is appropriate for team size and collaboration style
• Layer Design: Check if layers reflect business needs and have clear ownership
• Folder Structure: Verify folders follow naming conventions and project needs
• File Organization: Assess if files are properly named and organized

2. Naming Conventions

• snake_case Usage: All resources, variables, and outputs use snake_case
• Resource Naming: No stuttering, proper use of this/these, meaningful names
• Variable Naming: Collections are plural, maps reflect key-value relationships
• File Naming: Reader-friendly names, avoid main.tf

3. Module Standards

• Module Purpose: Created for multiple resource instantiation or complexity hiding
• Anti-patterns: No pass-through modules
• Versioning: Proper version pinning for remote modules
• Documentation: README.md and terraform-docs usage

4. Versioning & Dependencies

• Environment Layers: Exact versions for Terraform and providers
• Modules: Flexible versions with ~> syntax
• Lock Files: Committed .terraform.lock.hcl files
• Remote Modules: Pinned to specific versions/tags

5. Code Quality & Security

• Quality Automation: Either pre-commit hooks OR CI/CD pipeline for tflint, terraform fmt, checkov (not both required)
• Secret Management: No plain text passwords, keys, or secrets; proper data source usage for sensitive values
• Provider Configuration: No provider blocks in modules
• Red Flags: No workspace usage, no one-liners, proper state management
• Note: Subscription IDs, tenant IDs, and Azure AD group IDs are public identifiers, not sensitive information

6. Cross-Layer References

• Data Sources: Preferred over hardcoded strings
• Remote State: Proper usage for layer communication
• Dependencies: Clear and documented

Audit Process

1. Analyze codebase structure using file and semantic search
2. Assess maturity level for each category against IaC maturity model
3. Identify risk factors and classify by impact severity
4. Determine overall maturity using risk-weighted assessment
5. Generate actionable recommendations prioritized by risk and effort

Maturity Assessment Framework

Maturity Criteria by Category

Project Structure & Patterns

• Level 5: Pattern perfectly aligned with team/business needs, automated governance
• Level 4: Consistent pattern implementation, documented standards
• Level 3: Clear pattern choice, mostly consistent implementation
• Level 2: Some structure present, inconsistent application
• Level 1: Ad-hoc structure, no clear patterns

Naming & Standards

• Level 5: Automated enforcement, comprehensive conventions
• Level 4: Consistent application, documented standards
• Level 3: Clear conventions followed, minor deviations
• Level 2: Basic naming rules, some inconsistencies
• Level 1: Inconsistent naming, no clear standards

Security & Quality

• Level 5: Continuous security monitoring, automated compliance
• Level 4: Comprehensive security practices, regular audits
• Level 3: Security basics implemented, documented processes
• Level 2: Some security measures, ad-hoc implementation
• Level 1: Minimal security considerations

Note: Only passwords, keys, certificates, tokens, and other authentication credentials are considered sensitive. Public identifiers like subscription IDs, tenant IDs, and resource IDs are not security risks.

Risk-Based Weighting

• Security & Compliance: 35% (highest risk impact)
• Architecture & Patterns: 25% (structural foundation)
• Standards & Quality: 20% (maintainability impact)
• Documentation & Process: 12% (team efficiency)
• Tooling & Automation: 8% (operational efficiency)

Audit Execution Instructions

1. Determine audit scope:

   • If {{folder}} is provided, focus analysis on that directory: {{folder}}
   • If no folder specified, audit the entire workspace
   • Use list_dir to explore the target directory structure

2. Maturity assessment process:

   • Use codebase, file_search, and semantic_search to understand project layout
   • Assess current maturity level for each category against the 5-level model
   • Identify risk factors and classify by impact (Critical/High/Medium/Low)
   • Determine gaps to reach next maturity level

3. Risk-based evaluation:

   • Prioritize findings by risk impact using the weighting system
   • Focus on critical risks that could impact production, security, or compliance
   • Assess operational and maintenance risks for medium-term planning

4. Evidence-based assessment:

   • Reference specific files and line numbers for all findings
   • Provide quantitative metrics where possible (percentages, counts)
   • Document patterns and anti-patterns with concrete examples

5. Actionable recommendations:

   • Prioritize actions by risk reduction and maturity improvement
   • Provide clear implementation guidance for each recommendation

Begin the audit now by exploring the target scope, then systematically assess maturity and risk factors for each category.
