# Asset Classification

> Policy-driven classification engine categorizing assets by environment, sensitivity, and compliance scope.

Asset classification ensures that security teams focus remediation efforts where business impact is highest.

***

## Dynamic Classification Rules

Snapsec allows you to define YAML-based classifiers that evaluate asset metadata and apply classification tiers automatically:

```yaml theme={null}
classifier:
  name: "PCI-DSS Production Scope"
  target_tier: "Tier 1 (Mission Critical)"
  rules:
    any:
      - hostname: "*payment*"
      - hostname: "*checkout*"
      - tag: "pci == 'true'"
      - subnet: "10.200.0.0/16"
```

***

## Criticality Tiers

* **Tier 1 (Critical)**: Production environments processing payment data (PCI), health records (HIPAA), or sensitive PII.
* **Tier 2 (High)**: Core customer-facing APIs and internal corporate authentication infrastructure.
* **Tier 3 (Medium)**: Staging, QA, and integration testing environments.
* **Tier 4 (Low)**: Ephemeral dev sandboxes and local testing nodes.
