Validation Rules

Terraform Security Rules

1. Storage Encryption

hcl # ❌ Bad - Unencrypted EBS volume resource "aws_ebs_volume" "example" { size = 100 # encrypted = false # Missing encryption }

# ✅ Good - Encrypted EBS volume resource "aws_ebs_volume" "example" { size = 100 encrypted = true }

1. Security Group Configuration

hcl # ❌ Bad - Open to world resource "aws_security_group" "example" { ingress { from_port = 22 to_port = 22 protocol = "tcp" cidr_blocks = "0.0.0.0/0"] # Too open } }

# ✅ Good - Restricted access resource "aws_security_group" "example" { ingress { from_port = 22 to_port = 22 protocol = "tcp" cidr_blocks = "10.0.0.0/8"] # Restricted } }

Kubernetes Security Rules

1. Security Context

yaml # ❌ Bad - No security context apiVersion: v1 kind: Pod spec: containers:

• name: app

image: nginx # Missing security context

# ✅ Good - With security context apiVersion: v1 kind: Pod spec: securityContext: runAsNonRoot: true runAsUser: 1000 fsGroup: 2000 containers:

• name: app

image: nginx securityContext: allowPrivilegeEscalation: false readOnlyRootFilesystem: true

1. Resource Limits

yaml # ❌ Bad - No resource limits apiVersion: v1 kind: Pod spec: containers:

• name: app

image: nginx # Missing resources section

# ✅ Good - With resource limits apiVersion: v1 kind: Pod spec: containers:

• name: app

image: nginx resources: requests: memory: "64Mi" cpu: "250m" limits: memory: "128Mi" cpu: "500m"

Cost Estimation Algorithm

The cost estimation uses a multi-factor approach:

1. Resource Pricing: Real-time cloud provider pricing data
2. Usage Patterns: Historical usage data and projections
3. Regional Variations: Price differences across regions
4. Volume Discounts: Enterprise pricing and volume discounts
5. Optimization Opportunities: Rightsizing and alternative options

Compliance Validation

The skill validates against multiple compliance frameworks:

CIS Controls

• Access control
• Audit logging
• Data encryption
• Network security
• Vulnerability management

NIST 800-53

• Security and privacy controls
• Risk management
• System and communications protection
• System and information integrity

SOC2

• Security
• Availability
• Processing integrity
• Confidentiality
• Privacy

Best Practices

1. IaC Development

• Use consistent naming conventions
• Implement modular design
• Include comprehensive documentation
• Use version control effectively

2. Security Integration

• Implement security checks early in development
• Use automated security scanning
• Regularly update security rules
• Monitor for new vulnerabilities

3. Cost Management

• Regularly review resource utilization
• Implement cost monitoring
• Use reserved instances where appropriate
• Optimize storage and data transfer

4. Compliance Management

• Map compliance requirements to technical controls
• Maintain compliance evidence
• Regular compliance assessments
• Continuous compliance monitoring

IDE Integration

json
// .vscode/settings.json
{
  "iac-validator.autoValidate": true,
  "iac-validator.severityThreshold": "medium",
  "iac-validator.frameworks": ["CIS", "NIST"],
  "iac-validator.costEstimation": true,
  "iac-validator.notificationChannels": ["slack"]
}

Performance Considerations

Optimization Tips

1. Parallel Processing: Validate multiple files in parallel
2. Caching: Cache validation results and pricing data
3. Incremental Validation: Only validate changed files
4. Batch Processing: Process multiple resources together

Resource Usage

• Memory: ~2GB for large-scale IaC validation
• CPU: High usage during security analysis and cost estimation
• Network: High usage during cloud API calls for pricing
• Storage: ~1GB for validation cache and reports

Security Considerations

Data Protection

• All cloud credentials are encrypted at rest
• IaC configurations are processed in memory only
• Validation reports are stored securely
• Sensitive data is redacted in reports

Access Control

• Role-based access for validation operations
• Audit logging for all validation activities
• Secure API key management
• Network segmentation for validation workloads
