# IaC Security Scanner Skill

## Purpose

Infrastructure as Code security scanning and policy enforcement to identify misconfigurations, security vulnerabilities, and compliance violations in cloud infrastructure definitions before deployment.

## Capabilities

### Terraform Security Scanning
- Scan Terraform configurations for security misconfigurations
- Check for exposed resources (public S3 buckets, open security groups)
- Validate encryption settings for data at rest and in transit
- Detect hardcoded secrets in Terraform files
- Analyze Terraform state files for sensitive data exposure

### CloudFormation Analysis
- Scan CloudFormation templates for security issues
- Check IAM policy configurations for least privilege
- Validate network configuration security
- Detect insecure default configurations

### Kubernetes Manifest Scanning
- Analyze Kubernetes YAML manifests for security issues
- Check pod security standards compliance
- Validate resource limits and quotas
- Detect privileged containers and host path mounts

### Pulumi Code Analysis
- Scan Pulumi TypeScript/Python code for security issues
- Check cloud resource configurations
- Validate security best practices

### Policy Enforcement
- Define and enforce custom security policies using OPA/Rego
- Create guardrails for cloud resource configurations
- Block deployments that violate security policies
- Generate policy compliance reports

### Compliance Mapping
- Map findings to compliance frameworks (CIS, NIST, SOC 2, PCI-DSS)
- Generate compliance gap analysis reports
- Track remediation progress against compliance requirements

## Integrations

- **Checkov**: Multi-cloud IaC scanner by Bridgecrew
- **tfsec**: Terraform security scanner
- **KICS**: Keeping Infrastructure as Code Secure

- **Snyk IaC**: Infrastructure as Code security testing

## Target Processes

- IaC Security Scanning Process
- Cloud Security Architecture Review
- DevSecOps Pipeline Integration
- Infrastructure Deployment Pipeline
- Compliance Continuous Monitoring
