网站就必须需要ssl证书吗?

       网站的SSL证书有什么用? SSL协议是提供网络通信的安全和可靠的数据完整性。 TLS和SSL的网络连接的传输层在用于安全性来保护网络数据传输,使用的数据加密,以确保数据被加密不能在网络中传输期间被截取和窃听。

       现在,百度谷歌等主流浏览器技术都在进行打击“非安全”网站。“非安全”网站也就是我们没有系统安装SSL证书还在研究使用http协议的网站,会在一个浏览器中发出提示对于红色不安全的警告。

        SSL证书保护网站免受欺诈、数据泄漏和许多其他来自钓鱼网站的威胁,并可以为访问者和网站构建安全的网络环境,允许用户自由浏览。

       提升品牌形象和可信度

       部署 ssl 证书的站点会在浏览器的地址栏中显示 https 绿色安全锁,如果部署 ev ssl 证书,还会显示绿色地址栏和单元名称。用户可以被告知,他们正在访问一个安全可靠的网站,可以放心的操作和交易,有效地提高了公司的品牌信息和信誉。

       网站身份认证,以防止假冒

       没有相关证书的网站,黑客技术可以进行伪造一个与网站类似的域名制造钓鱼网站。网站部署受信任的SSL证书后,用户可识别网站内容是否为官网。浏览器内置安全管理机制,实时查验证书状态,通过不同浏览器显示国家安全锁、绿色地址栏、单位产品名称、证书以及信息等方式,展示中国网站身份、认证服务信息,让用户能够轻松识别网站真实社会身份,防止仿冒。

       网站信息加密防止篡改

       SSL证书最重要的是要确保数据的安全性,HTTP协议中明文内容是不断发送,攻击者很容易被截获从客户端和服务器传输明文数据,直接访问它的重要信息;和用于数据加密处理HTTPS协议,第三方不能窃听。

       SSL证书让网站系统实现数据加密传输,可以进行很好的防止企业用户个人隐私信息,如用户名、密码、交易记录、居住环境信息等被窃取和纂改。
