基于PROFIsafe的网络安全防御应用研究

Network Security Defense Applied Research Based on PROFIsafe

工业纵向和横向一体化水平的不断提高,增加了自动化控制系统中的安全风险几率.通过对人、设备和环境造成危害故障的概率分析,利用安全模块与PROFIsafe(安全通信协议)相结合的方式降低了安全攻击的风险,实现了工业自动化系的安全防御,引用PROFINET IO安全模块改进了PROFIsafe的安全性能.

With vertical and horizontal integration of industrial increasing levels, increasing automation and control system security risks odds. Through the failure analysis of people, equipment, and environmental hazards probability, the risk of security attacks are reduced by using the security module with PROFIsafe combination, the industrial automation system security and defense are achieved, PROFIsafe safety performance are inproved by citing security module PROFINET IO.
