TLS安全策略说明

更新时间:

为全球加速实例配置HTTPS监听时,支持选择TLS安全策略。系统默认选择tls_cipher_policy_1_0安全策略,若您有更高的安全要求,可以根据需要选择更高等级的TLS安全策略。

TLS安全策略

TLS安全策略包含HTTPS可选的TLS协议版本和配套的加密算法套件。TLS协议版本越高,HTTPS通信的安全性越高,但是相较于低版本TLS协议,高版本TLS协议对浏览器的兼容性较差。TLS安全策略对应的TLS协议版本和配套的加密算法套件如下:

选择TLS安全策略

在您添加或者配置HTTPS监听时,系统默认选择tls_cipher_policy_1_0安全策略。您可以通过修改高级配置选择TLS安全策略。具体操作,请参见添加HTTP或HTTPS协议监听选择TLS安全策略
