1993年,中国第一条64K专线接通了国际互联网,弹指10年间,网络时代给我们的工作,生活带来了巨大的变化。这10年,网络以几何级数式的膨胀增长,网络传输的信息量空前增加,传统数据加上语音、视频、多媒体等大量的信息流,对于网络的带宽不断地提出了新的需求。另一方面,网络安全越来越成为一个不容忽视的课题。据IDC于2002年调查显示,在过去的5年中,每天都有因受到黑客攻击而造成严重损失的事件。安全产品和网络攻击如同矛和盾的较量,每一天都在演绎着网络安全新的传说。从1996年底到2002年初,国内安全市场经历了“军阀混战”的时期,安全厂商经受了一次大的洗礼。自2002年下半年至今,国内网络安全市场中,安全厂商优胜劣汰,形成了以几家大专业厂商为主导的局面。现在,就网络安全产品中的防
In 1993, the first 64K green line in China connected to the Internet, pointing to the past 10 years, brought great changes to our work and life in the Internet age. In the past 10 years, the network has grown in a geometric progression. The amount of information transmitted over the Internet has been increasing.

Security products and cyber attacks act like spears and shields, evolving new legends of cybersecurity every day. From the end of 1996 to the beginning of 2002, the domestic security market experienced a period of “melee of warlords,” and security vendors experienced a major baptism. Since the second half of 2002, in the domestic network security market, the security vendors have survived the competition and the dominant situation has taken shape with several major specialized manufacturers. Now, anti-cyber security products
