# Security

## Best Practices

1. **Keep Everything Updated**:
   - Regularly update K3s
   - Update all infrastructure components
   - Keep application images up to date

2. **Network Security**:
   - Use internal services whenever possible
   - Limit exposed services to only what's necessary
   - Configure your home router's firewall properly

3. **Access Control**:
   - Use strong passwords for all services
   - Implement a secrets management strategy
   - Rotate API tokens and keys regularly

4. **Regular Audits**:
   - Review running services periodically
   - Check for unused or outdated deployments
   - Monitor resource usage for anomalies

## Security Scanning (Future Implementation)

Tools to consider implementing:

1. **Trivy** for image scanning:
   ```bash
   # Example Trivy usage (placeholder)
   trivy image <your-image>
   ```

2. **kube-bench** for Kubernetes security checks:
   ```bash
   # Example kube-bench usage (placeholder)
   kubectl apply -f https://raw.githubusercontent.com/aquasecurity/kube-bench/main/job.yaml
   ```

3. **Falco** for runtime security monitoring:
   ```bash
   # Example Falco installation (placeholder)
   helm repo add falcosecurity https://falcosecurity.github.io/charts
   helm install falco falcosecurity/falco --namespace falco --create-namespace
   ```
