物联网的OT安全技术探讨
2020
Overview
物联网是一种将虚拟网络世界与现实物理世界相结合的综合信息技术, 具有广泛的应用和庞大的潜在市场. 但是, 物联网安全方面的现有技术远不能满足产业的需求. 本文指出物联网的安全问题与传统网络环境的信息安全(称为IT安全)有着本质区别. 传统网络安全保护的主要是信息, 因此使用IT安全技术. 本文强调物联网系统除了要保护信息安全外, 还需要对操作进行安全保护, 这类技术称为OT安全技术. 本文对OT安全的概念和内涵进行了描述, 指出OT安全是信息转化为物理活动行为的安全问题, 其安全防护的目标与传统的信息安全保护不同, 尽管在实现技术方面有许多类似的技术. 本文分析了IT安全与OT安全的特性, 这些特性包括物联网中的IT技术与OT技术相互作用和相互影响, 并阐述常用的IT安全与OT安全保护技术.
