# Protection Mechanism Failure (CWE-693)

The product does not use or incorrectly uses a protection mechanism that provides sufficient defense against directed attacks against the product.

**Stack:** Docker

- Prevalence: Hoch Häufig ausgenutzt
- Impact: Hoch 1 Regeln mit hohem Schweregrad
- Prevention: Dokumentiert 8 Fix-Beispiele

**OWASP:** Security Misconfiguration (A05:2021-Security Misconfiguration) - #5

## Description

This weakness covers three distinct situations: Missing a protection mechanism, using a faulty protection mechanism, or incorrectly applying a protection mechanism. A missing protection mechanism occurs when the application does not defend against a specific attack. A faulty protection mechanism occurs when the application does defend against a specific attack, but the protection mechanism is not implemented correctly.

## Prevention

Präventionsstrategien für Protection Mechanism Failure basierend auf 1 Shoulder-Erkennungsregeln.

### Docker

Add a HEALTHCHECK instruction to enable container health monitoring

## Warning Signs

- [LOW] Dockerfile has no HEALTHCHECK instruction for container health monitoring
- [LOW] Dockerfiles missing HEALTHCHECK instructions for container monitoring

## Consequences

- Schutzmechanismus umgehen
- Nicht autorisierten Code ausführen
- Privilegien erlangen

## Mitigations

- Mehrere Sicherheitsebenen umsetzen (Defense in Depth)
- Branchenübliche, geprüfte Sicherheitsmechanismen statt eigener Implementierungen verwenden
- Sicherstellen, dass Schutzmechanismen weder umgangen noch deaktiviert werden können

## Detection

- Total rules: 8
- Languages: dockerfile, go, javascript, typescript

## Rules by Language

### Dockerfile (1 rules)

- **Missing Healthcheck Configuration** [LOW]: Detects Dockerfiles missing HEALTHCHECK instructions for container monitoring.
  - Remediation: Add a HEALTHCHECK instruction to monitor container health.

```dockerfile
HEALTHCHECK --interval=30s --timeout=10s --retries=3 \
  CMD curl -f http://localhost:8080/health || exit 1
```
