<!-- overview -->

<!--
This page describes security considerations and best practices specific to the Windows operating system.
-->
本篇介绍特定于 Windows 操作系统的安全注意事项和最佳实践。

<!-- body -->

<!--
## Protection for Secret data on nodes
-->
## 保护节点上的 Secret 数据   {#protection-for-secret-data-on-nodes}

<!--
On Windows, data from Secrets are written out in clear text onto the node's local
storage (as compared to using tmpfs / in-memory filesystems on Linux). As a cluster
operator, you should take both of the following additional measures:
-->
在 Windows 上，来自 Secret 的数据以明文形式写入节点的本地存储
（与在 Linux 上使用 tmpfs / 内存中文件系统不同）。
作为集群操作员，你应该采取以下两项额外措施：

<!--
1. Use file ACLs to secure the Secrets' file location.
1. Apply volume-level encryption using
   [BitLocker](https://docs.microsoft.com/windows/security/information-protection/bitlocker/bitlocker-how-to-deploy-on-windows-server).
-->
1. 使用文件 ACL 来保护 Secret 的文件位置。
2. 使用 [BitLocker](https://docs.microsoft.com/windows/security/information-protection/bitlocker/bitlocker-how-to-deploy-on-windows-server)
   进行卷级加密。

<!--
## Container users
-->
## 容器用户   {#container-users}

<!--
[RunAsUsername](/docs/tasks/configure-pod-container/configure-runasusername)
can be specified for Windows Pods or containers to execute the container
processes as specific user. This is roughly equivalent to
[RunAsUser](/docs/concepts/security/pod-security-policy/#users-and-groups).
-->
可以为 Windows Pod 或容器指定 [RunAsUsername](/zh-cn/docs/tasks/configure-pod-container/configure-runasusername)
以作为特定用户执行容器进程。这大致相当于 [RunAsUser](/zh-cn/docs/concepts/security/pod-security-policy/#users-and-groups)。

<!--
Windows containers offer two default user accounts, ContainerUser and ContainerAdministrator.
The differences between these two user accounts are covered in
[When to use ContainerAdmin and ContainerUser user accounts](https://docs.microsoft.com/virtualization/windowscontainers/manage-containers/container-security#when-to-use-containeradmin-and-containeruser-user-accounts)
within Microsoft's _Secure Windows containers_ documentation.
-->
Windows 容器提供两个默认用户帐户，ContainerUser 和 ContainerAdministrator。
在微软的 **Windows 容器安全** 文档
[何时使用 ContainerAdmin 和 ContainerUser 用户帐户](https://docs.microsoft.com/zh-cn/virtualization/windowscontainers/manage-containers/container-security#when-to-use-containeradmin-and-containeruser-user-accounts)
中介绍了这两个用户帐户之间的区别。

<!--
Local users can be added to container images during the container build process.
-->
在容器构建过程中，可以将本地用户添加到容器镜像中。


<div class="alert alert-info" role="note"><h4 class="alert-heading">说明：</h4><!--
* [Nano Server](https://hub.docker.com/_/microsoft-windows-nanoserver) based images run as
  `ContainerUser` by default
* [Server Core](https://hub.docker.com/_/microsoft-windows-servercore) based images run as
  `ContainerAdministrator` by default
-->
<ul>
<li>基于 <a href="https://hub.docker.com/_/microsoft-windows-nanoserver">Nano Server</a> 的镜像默认以 <code>ContainerUser</code> 运行</li>
<li>基于 <a href="https://hub.docker.com/_/microsoft-windows-servercore">Server Core</a> 的镜像默认以 <code>ContainerAdministrator</code> 运行</li>
</ul>
</div>


<!--
Windows containers can also run as Active Directory identities by utilizing
[Group Managed Service Accounts](/docs/tasks/configure-pod-container/configure-gmsa/)
-->
Windows 容器还可以通过使用[组管理的服务账号](/zh-cn/docs/tasks/configure-pod-container/configure-gmsa/)作为
Active Directory 身份运行。

<!--
## Pod-level security isolation
-->
## Pod 级安全隔离   {#pod-level-security-isolation}

<!--
Linux-specific pod security context mechanisms (such as SELinux, AppArmor, Seccomp, or custom
POSIX capabilities) are not supported on Windows nodes.
-->
Windows 节点不支持特定于 Linux 的 Pod 安全上下文机制（例如 SELinux、AppArmor、Seccomp 或自定义 POSIX 权能字）。

<!--
Privileged containers are [not supported](/docs/concepts/windows/intro/#compatibility-v1-pod-spec-containers-securitycontext)
on Windows.
Instead [HostProcess containers](/docs/tasks/configure-pod-container/create-hostprocess-pod)
can be used on Windows to perform many of the tasks performed by privileged containers on Linux.
-->
Windows 上[不支持](/zh-cn/docs/concepts/windows/intro/#compatibility-v1-pod-spec-containers-securitycontext)特权容器。
然而，可以在 Windows 上使用 [HostProcess 容器](/zh-cn/docs/tasks/configure-pod-container/create-hostprocess-pod)来执行
Linux 上特权容器执行的许多任务。
