Por ejemplo, digamos que tienes 4 endpoints de API (*path operations*):

* `/items/public/`
* `/items/private/`
* `/users/{user_id}/activate`
* `/items/pro/`

entonces podrías agregar diferentes requisitos de permiso para cada uno de ellos solo con dependencias y sub-dependencias:

```mermaid
graph TB

current_user(["current_user"])
active_user(["active_user"])

		// httpclient target is part of ListenNotification
		// which doesn't need to be listed as part of the ARN list
		// This list is only meant for external targets, filter
		// this out pro-actively.
		if !strings.HasPrefix(targetID.ID, "httpclient+") {
			arns = append(arns, targetID.ToARN(region).String())
		}
	}

	return arns
}

// Loads notification policies for all buckets into EventNotifier.

	oauth2Config := oauth2.Config{
		ClientID:     pro.ClientID,
		ClientSecret: pro.ClientSecret,
		RedirectURL:  pro.RedirectURL,

		// Discovery returns the OAuth2 endpoints.
		Endpoint: provider.Endpoint(),

		// "openid" is a required scope for OpenID Connect flows.
		Scopes: []string{oidc.ScopeOpenID, "groups"},
	}

	state := fmt.Sprintf("x%dx", time.Now().Unix())

* `/users/{user_id}/activate`
* `/items/pro/`

그 다음 각각에 대해 그저 의존성과 하위 의존성을 사용하여 다른 권한 요구 사항을 추가할 수 있을 겁니다:

```mermaid
graph TB

current_user(["current_user"])
active_user(["active_user"])
admin_user(["admin_user"])
paying_user(["paying_user"])

public["/items/public/"]
private["/items/private/"]
activate_user["/users/{user_id}/activate"]
pro_items["/items/pro/"]

current_user --> active_user

	credElement := strings.TrimPrefix(strings.Split(strings.TrimSpace(v4Auth), ",")[0], signV4Algorithm)
	// Replace all spaced strings, some clients can send spaced
	// parameters and some won't. So we pro-actively remove any spaces
	// to make parsing easier.
	v4Auth = strings.ReplaceAll(v4Auth, " ", "")
	if v4Auth == "" {
		return sv, ErrAuthHeaderEmpty
	}

	// Verify if the header algorithm is supported or not.

#### Ein „professioneller“ Angriff

Natürlich würden die Angreifer das alles nicht von Hand versuchen, sondern ein Programm dafür schreiben, möglicherweise mit Tausenden oder Millionen Tests pro Sekunde. Und würden jeweils nur einen zusätzlichen richtigen Buchstaben erhalten.
