互联网如今已经渗入生活的方方面面,人们对网络安全也越发重视。安全性的话题更是不断推到风口浪尖。其实本质上讲,网络安全就是网络上的信息安全。广义上说,凡是涉及到网络信息的保密性、完整性、可用性、真实性和可控性得相关技术和理论都是属于网络安全的范畴。
对于网站这种纯粹的互联网的产物更应该将信息安全放在了首位。从源头开始就要加密传输。所以在选择和设置服务器方面也要多加考虑信息的安全性。美国著名主机商HostEase在信息安全方面做得就很不错,服务器运行过程中,24小时监控、扫描、检测、加密、认证、防攻击、防病毒以及审计保证主机99.9%的时间正常运行着。
HostEase虚拟主机支持SSL证书,可将数据传输加密应用到每一台主机方案。利用SSL协议的端到端加密是为数据从一端到另一端提供的加密方式,这样数据在发送端就被加密,在接收端再被解密,中间节点处不以明文的形式出现。端到端加密在应用层完成的。在端到端加密中,报文均以密文的形式贯穿于全部传输过程,只是在发送端和接收端才有加解密设备,而在中间任何节点报文均不解密。通过这个方式保证用户和网站交互式的信息安全。
除了HostEase虚拟主机对于信息传输的加密技术,HostEase服务商提供的防火墙技术不仅能够准确防御已知的网络攻击,而且还具备预防未知攻击的能力,来防范黑客的攻击。尤其在防范DDOS攻击方面,除去一般性防火墙的保护。HostEase还推出了洛杉矶高防服务器,着重加强了DDOS抗击力。
网络安全是推动互联网发展和电子商务的关键,发展网络安全技术是目前面临的迫切要求,除了上述服务器端加密和防护技术外,网络与信息安全还涉及到其他很多方面的技术与知识,例如:黒客技术、入侵检测技术、病毒防护技术、信息隐藏技术等。一个完善的网站服务器安全保障系统,应该根据具体需求对上述安全技术进行取舍。
