    • Techniques for destination domain extraction for secure protocols are disclosed. In some embodiments, destination domain extraction for secure protocols includes monitoring network communications between a client and a remote server; determining if the client sends a request to create a secure connection with the remote server (e.g., in which the network communications are initiating a setup for a secure protocol-based connection); and extracting a destination domain from the request to create the secure connection with the remote server. In some embodiments, the secure protocol is a secure sockets layer (SSL) protocol or transport layer security (TLS) protocol, and the destination domain is extracted from the server name indication (SNI) of a client hello message sent from the client to the remote server. In some embodiments, destination domain extraction for secure protocols further includes applying a policy (e.g., a security policy) based on the destination domain to filter traffic using a security device.
    • 公开了用于安全协议的目的域提取的技术。 在一些实施例中,用于安全协议的目的地域提取包括监视客户端和远程服务器之间的网络通信; 确定客户端是否发送与远程服务器建立安全连接的请求(例如,其中网络通信正在启动用于基于安全协议的连接的设置); 并从请求中提取目的地域以创建与远程服务器的安全连接。 在一些实施例中,安全协议是安全套接层(SSL)协议或传输层安全性(TLS)协议,并且从客户端发送到客户端的客户端hello消息的服务器名称指示(SNI)中提取目的地域 远程服务器。 在一些实施例中,用于安全协议的目的地域提取还包括基于目的地域应用策略(例如,安全策略)来使用安全设备来过滤业务。
