 -  **Token validation**：The token fetched from api will be invalid immediately after it's used once, and it expires after 5 minutes if not used. 
--  **Authentication**：By default all resources can be accessed without any authentication, to restrict anonymous access, you can enable the  basic authentication of gotty, see [how to](https://github.com/KubeOperator/webkubectl/blob/master/gotty/GOTTY_USAGE.md#options).

 -  **SSL/TLS**：By default all traffic between the server and clients are NOT encrypted, we recommend you enable SSL/TLS option of gotty, see [how to](https://github.com/KubeOperator/webkubectl/blob/master/gotty/GOTTY_USAGE.md#options). Alternatively you can deploy Web Kubectl behind a proxy and enable SSL/TLS for the proxy, please note that the proxy should support WebSocket protocol.

 -  **SSL/TLS**：默认情况下，服务器与客户端之间的所有流量均未加密，我们建议您启用gotty的SSL / TLS选项，请参见[操作方法](https://github.com/KubeOperator/webkubectl/blob/master/gotty/GOTTY_USAGE.md#options)。或者，您可以在代理后面部署Web Kubectl并为该代理启用SSL / TLS，请注意，您的代理需要支持WebSocket协议。
