# CloudWatch Canary 的必要角色和許可
建立和管理 Canary 的使用者以及 Canary 本身都必須具有特定許可。
## AWS CloudWatch Synthetics 的 受管政策
若要新增許可給使用者、群組和角色，使用 AWS 受管政策比自行撰寫政策更容易。建立 IAM 客戶受管政策需要時間和專業知識，而受管政策可為您的團隊提供其所需的許可。若要快速開始使用，您可以使用我們的 AWS 受管政策。這些政策涵蓋常見的使用案例，並可在您的帳戶中使用 AWS 。如需 AWS 受管政策的詳細資訊，請參閱《IAM 使用者指南》中的[AWS 受管政策](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_managed-vs-inline.html#aws-managed-policies) AWS 受管政策。
AWS 服務會維護和更新 AWS 受管政策。您無法變更 AWS 受管政策中的許可。服務偶爾會變更 AWS 受管政策中的許可。此類型的更新會影響已連接政策的所有身分識別 (使用者、群組和角色)。
