沈昌祥:应构建计算机安全主动免疫3.0系统

2017-08-24 21:05:42   央广网

2017中国(广东)安全可靠应用推进大会今日在广州召开

央广网广州8月24日消息(记者官文清)今年以来,从5月份的“Wannacry”到6月份的“Petrwrap”,勒索病毒的两次爆发敲响了网络安全的警钟。在今日召开的2017中国(广东)安全可靠应用推进大会上,中国工程院院士沈昌祥表示,在网络已成为国民经济命脉必不可缺的重要组成部分的现状下,社会和企业所面临的网络信息安全风险成倍放大,构建网络安全和计算机主动免疫系统迫在眉睫。

8月24日,2017中国(广东)安全可靠应用推进大会在广州召开,该活动由广东省电子政务协会、工信部电子第五研究所主办,旨在在围绕安全可靠技术与网络空间安全的创新发展和实践成果进行深入交流,全面展示和共同分享我国安全可靠技术应用及产业发展的最新成果。

大会上,沈昌祥认为,人们对IT的认知逻辑的局限性,不能穷尽所有组合,只能局限于完成计算任务去设计IT系统,必定存在逻辑不全的缺陷,相当于新生儿一般缺乏免疫系统,从而难以应对人为利用缺陷进行攻击。而真正的计算机不仅要计算,还要有防护部件,必须从逻辑正确验证、计算体系结构和计算模式创新来解决,这样才能防止重大的体系结构问题。

而信息安全产业的迅猛发展也从侧面印证了当前企业网络安全形势严峻。来自市场研究机构前瞻产业研究院的数据显示,2016年全球信息安全行业市场规模约为2392.51亿元,同比增长19.16%。在我国,2016年信息安全产业市场规模也达到了477亿元,未来5年预计将保持10%以上的增长。

网络安全事关重大,那么怎样才能实现主动免疫的防御?沈昌祥以今年两次的勒索病毒袭击为例指出,中国凭借自主创新的可信计算3.0系统,通过在计算机信息系统和网络上建立对未知病毒木马以及系统漏洞的防御,两次成功抵御勒索病毒的侵扰。与其他国家轻则给国民造成严重困扰、重则造成社会设施和秩序混乱甚至瘫痪相比,中国互联网受到勒索病毒的影响微乎其微。
