本题考查电子商务基础知识。
SSH协议:SSH为建立在应用层和传输层基础上的安全协议。SSH是目前较可靠,专为远程登录会话和其他网络服务提供安全性的协议。利用SSH协议可以有效防止远程管理过程中的信息泄露问题。
IDS协议:即“入侵检测系统”。专业上讲就是依照一定的安全策略,通过软、硬件,对网络、系统的运行状况进行监视,尽可能发现各种攻击企图、攻击行为或者攻击结果,以保证网络系统资源的机密性、完整性和可用性。
SSL协议:SSL(Secure Sockets Layer安全套接层)协议,及其继任者TLS(Transport Layer Security传输层安全)协议,是为网络通信提供安全及数据完整性的一种安全协议。TLS与SSL在传输层对网络连接进行加密,用于保障网络数据传输安全,利用数据加密技术,确保数据在网络传输过程中不会被截取及窃听。
TLS协议:安全传输层协议(TLS)用于在两个通信应用程序之间提供保密性和数据完整性。该协议由两层组成:TLS记录协议(TLS Record)和TLS握手协议(TLS Handshake)。
