自定义权限策略配置参考示例-云监控-阿里云

如果系统权限策略不能满足您的要求，您可以创建自定义权限策略实现最小授权。使用自定义权限策略有助于实现权限的精细化管控，是提升资源访问安全的有效手段。本文介绍云监控使用自定义权限策略的场景和策略示例。

什么是自定义权限策略

在基于RAM的访问控制体系中，自定义权限策略是指在系统权限策略之外，您可以自主创建、更新和删除的权限策略。自定义权限策略的版本更新需由您来维护。

创建自定义权限策略后，需为RAM用户、用户组或RAM角色绑定权限策略，这些RAM身份才能获得权限策略中指定的访问权限。
已创建的权限策略支持删除，但删除前需确保该策略未被引用。如果该权限策略已被引用，您需要在该权限策略的引用记录中移除授权。
自定义权限策略支持版本控制，您可以按照RAM规定的版本管理机制来管理您创建的自定义权限策略版本。
