Foglio Informativo dello Strumento di Valutazione della Sicurezza di Azure

Panoramica

Azure Security Assessment Tool è un scanner di sicurezza basato su Rust, progettato per valutare gli ambienti Azure con oltre 200 regole di sicurezza. Questo strumento fornisce valutazioni di sicurezza automatizzate, verifica della conformità e identificazione delle vulnerabilità attraverso le sottoscrizioni Azure. Offre report dettagliati e indicazioni per la bonifica per aiutare le organizzazioni a migliorare la loro postura di sicurezza Azure.

⚠️ Avvertenza: Utilizzare Azure Security Assessment Tool solo in ambienti di proprietà o per i quali si ha un’autorizzazione esplicita di test. L’uso non autorizzato può violare i termini di servizio o le leggi locali.

```### Automazione PowerShell
```bash
# Check Azure CLI authentication
az account show

# Re-authenticate
az login --tenant "tenant-id"

# Verify service principal permissions
az role assignment list --assignee "service-principal-id"

# Test API access
az rest --method get --url "https://management.azure.com/subscriptions/your-sub-id/resources?api-version=2021-04-01"
```## Risoluzione dei Problemi
```bash
# Check required permissions
az role definition show --name "Security Reader"

# Grant additional permissions
az role assignment create \
  --assignee "principal-id" \
  --role "Reader" \
  --scope "/subscriptions/subscription-id"

# List current permissions
az role assignment list --assignee "principal-id" --output table
```### Problemi Comuni
```bash
# Reduce parallel requests
azucar assess --parallel 5

# Increase timeout
azucar assess --timeout 60

# Assess specific regions only
azucar assess --regions "eastus"

# Exclude large resource types
azucar assess --exclude-types "Microsoft.Compute/virtualMachines"
```#### Problemi di Autenticazione
```bash
# Validate custom rules
azucar rules validate --rules-path "./custom_rules"

# Test specific rule
azucar assess --rule-id "AZR-001" --dry-run

# Debug rule execution
azucar assess --rule-id "AZR-001" --verbose --debug

# Export default rules for reference
azucar rules export --output default-rules.json
```#### Problemi di Autorizzazione
```bash
# Enable debug logging
export RUST_LOG=debug
azucar assess --verbose

# Save logs to file
azucar assess --verbose 2>&1|tee assessment.log

# Check specific rule execution
azucar assess --rule-id "AZR-001" --debug

# Validate configuration
azucar config validate
