Auditing Terraform Infrastructure For Security

Overview

Cybersecurity skill for auditing terraform infrastructure for security. Follows industry best practices and security standards.

When to Use

Trigger phrases:

• "auditing terraform infrastructure for security"

• "Auditing Terraform infrastructure-as-code for security misconfigurations using C"

• When integrating security scanning into CI/CD pipelines for Terraform deployments

• When reviewing Terraform plans and modules for security best practices before applying

• When building policy-as-code guardrails for cloud infrastructure provisioning

• When auditing existing Terraform state files to identify deployed misconfigurations

• When enforcing organizational security standards across multiple Terraform projects

Do not use for runtime security monitoring (use CSPM tools), for application security testing (use SAST/DAST tools), or for cloud configuration drift detection (use AWS Config or Azure Policy after deployment).

When NOT to Use

• When you lack proper authorization for testing
• For production systems without change management
• When the task requires legal or compliance expertise beyond technical scope

Prerequisites

• Checkov installed (pip install checkov)
• tfsec installed (brew install tfsec or binary from GitHub)
• Terrascan installed (brew install terrascan)
• Terraform v1.0+ for plan generation
• OPA (Open Policy Agent) for custom policy enforcement
• Git repository with Terraform code to audit

Workflow

# Example: IOC detection
import re

IOC_PATTERNS = {
    "ip": r"\b(?:\d{1,3}\.){3}\d{1,3}\b",
    "domain": r"\b[a-z0-9-]+\.[a-z]{2,}\b",
    "hash_md5": r"\b[a-f0-9]{32}\b",
    "hash_sha256": r"\b[a-f0-9]{64}\b",
}

def extract_iocs() -> :
     {k: re.findall(v, text)  k, v  IOC_PATTERNS.items()}
