🛡️ Policy as Code

OPA Policy Enforcement

Kubernetes Admission Control:

Deny containers running as root
Require resource limits (CPU/memory)
Enforce health checks (liveness/readiness)
Validate component IDs against ArcLang model
Require security context for critical workloads

Terraform Validation:

Deny unencrypted storage
Require versioning for data buckets
Deny public database instances
Require KMS encryption for sensitive resources
Validate required tags (Component, Environment, ManagedBy)

Security Compliance:

PCI-DSS: Encryption at rest/in-transit
GDPR: EU data residency enforcement
HIPAA: SSL enforcement, storage encryption
SOC2: Audit logging, access controls

Cost Governance:

Monthly budget limits by environment
Instance cost warnings (GPU approval required)
Auto-termination for dev resources
Lifecycle policies for storage

Example OPA Policy

# Validate component IDs against ArcLang model
valid_component_ids := {
    "la-proc-001", "la-proc-002", "la-proc-003",
    "la-mig-001", "la-mig-002", "la-mig-003",
    "la-int-001", "la-anlz-001", "la-gov-001"
}

deny[msg] {
    resource := input.resource_changes[_]
    component := resource.change.after.tags.Component
    not component in valid_component_ids
    msg := sprintf("Invalid component ID '%s' - must match ArcLang model", [component])
}

🎯 Model Traceability

Every generated resource maintains full traceability back to the ArcLang model:

STK-002 (Stakeholder: Real-Time Analytics)
  ↓ satisfies
SYS-PERF-004 (System Requirement: Streaming Latency <60s)
  ↓ implements
LA-PROC-002 (Logical Component: Streaming Pipeline Engine)
  ↓ deploys to
PA-INT-001 (Physical Node: Integration Gateway)
  ↓ generates
AWS Lambda Function: streaming-processor
  • Runtime: Python 3.12
  • Memory: 1024 MB
  • Trigger: Kinesis (10 shards)
  • Tags: Component=LA-PROC-002, Requirement=SYS-PERF-004

Resource Tagging Example

resource "aws_lambda_function" "streaming_processor" {
  function_name = "streaming-processor"
  # ... configuration ...
  
  tags = {
    Component    = "LA-PROC-002"
    PhysicalNode = "PA-INT-001"
    Requirement  = "SYS-PERF-004"
    SafetyLevel  = "Medium"
    Environment  = "prod"
    ManagedBy    = "Terraform"
    GeneratedFrom = "ArcLang"
  }
}
