A series of cyber attacks show that the industrial Internet has long been the target of attacks in the cyber world.

VE4006P2 “The impact of cyber attacks in the industrial Internet sector is very large.” According to Wu Yunkun, in recent years, in the emergency response needs of industrial enterprise network attack incidents received by Qi ‘an Xin Security Center, involving dozens of enterprises in automobile production, intelligent manufacturing, energy and electricity, tobacco and other industries, most of the attack events have led to the blue screen of industrial hosts, important files are encrypted, and many of them have also led to shutdown and production. It has caused heavy losses to industrial enterprises.

“After the fact” does not meet the new security needs

In the traditional Internet era, cyber attacks mostly caused computer VE4006P2 crashes, privacy leaks and some property losses. In the era of digital economy, cyber attacks may directly affect the real physical world, and even lead to the paralysis of energy, transportation, medical, communications and other infrastructure, and the consequences may be catastrophic.

Why have major industrial system network security incidents occurred frequently in recent years, with increasing frequency and impact?

Du Lin, an engineer at the Security Research Institute of the China Academy of Information and Communications, said in an interview with a Science and Technology Daily reporter that from the perspective of the implementation of the security work layout, some enterprises have insufficient security awareness, inadequate protective measures, and insufficient technical industry support capacity, and China’s industrial manufacturing industry system is huge, and the security foundation is weak, it is urgent to “lay a baseline and build a defense line.”

VE4006P2 “From the perspective of industrial production, the networking of devices and the cloud of enterprises accelerate the transmission of security risks, and the network attack surface continues to expand from the boundary to the core.” Du Lin said that the transformation and upgrading of enterprise industrial production has made the industrial production network from closed to open, and intelligent equipment, industrial applications, production data, and system operation and maintenance have to be connected with the external network, facing huge security threats.

Wu Yunkun believes that in the traditional Internet era, people take “remedial measures after the fact” on network security habits, and these methods are often “head to head, foot to foot”, are local, for a single point, rather than thorough and comprehensive, and can not meet the security needs of the VE4006P2 new industrial Internet. At present, network security is in an important transition period, and traditional thinking and inertia have not changed in time, and can not keep up with the pace of the digital economy era.

“There are also industrial asset types and distribution conditions that are unclear, and the protection system cannot determine the security risks and attacked parts in a timely manner.” In addition, equipment disconnection, shutdown, abnormal operation and other difficult to locate problems, also aggravate the difficulty of safety protection.” Wu Yunkun said.
