Checking Infrastructure Compliance

Checking Infrastructure Compliance

Overview

Audit infrastructure configurations against compliance frameworks (CIS Benchmarks, SOC 2, HIPAA, PCI-DSS, GDPR) using policy-as-code tools like Open Policy Agent (OPA), Checkov, and tfsec. Generate compliance reports, identify violations, and produce remediation plans for Terraform, Kubernetes, and cloud provider configurations.

Prerequisites

• Policy-as-code tool installed: checkov, tfsec, opa, or kube-bench
• Infrastructure-as-code files (Terraform, CloudFormation, Kubernetes manifests) in the project
• Cloud provider CLI authenticated with read access to resources
• Compliance framework requirements documented (CIS, SOC 2, HIPAA, PCI-DSS)
• jq for parsing JSON policy outputs

Instructions

1. Identify the applicable compliance framework(s) based on industry and data classification
2. Scan Terraform files with checkov -d . or tfsec . to detect misconfigurations
3. Scan Kubernetes manifests for security issues: missing resource limits, privileged containers, missing network policies
4. Validate IAM policies for least-privilege violations using cloud-native tools (aws iam access-analyzer)
5. Check encryption at rest and in transit: verify S3 bucket encryption, database TLS, and EBS volume encryption
6. Audit logging configurations: confirm CloudTrail/​Cloud Audit Logs are enabled and sent to immutable storage
7. Generate a compliance report mapping each finding to the relevant control (e.g., CIS AWS 2.1.1)
8. Produce remediation Terraform/​YAML patches for each violation with severity ranking (Critical, High, Medium, Low)
9. Set up CI/​CD integration so compliance checks block merges on Critical/​High violations

Output

• Compliance scan results in JSON/​SARIF format for CI integration
• Markdown compliance report with control mappings and pass/​fail status
• Remediation code patches (Terraform diffs, Kubernetes manifest updates)
• OPA/​Rego policy files for custom organizational rules
• CI/​CD pipeline step configuration for automated compliance gating

Error Handling

Examples

• "Run a CIS Benchmark compliance check against all Terraform files and generate a report with remediation steps for Critical findings."
• "Create OPA policies that enforce: all S3 buckets must have encryption, all EC2 instances must have IMDSv2, and all security groups must not allow 0.0.0.0/​0 ingress."
• "Scan Kubernetes manifests for PCI-DSS compliance: verify no privileged containers, all pods have resource limits, and network policies exist for every namespace."
