What challenges does Zhou think exist in network security?

Zhou believes that the harm of network security has expanded from the online cyberspace affected by traditional cyber attacks to national security, national defense security, key infrastructure security, social security, family security, and even personal safety. Therefore, Zhou believes that network security has entered the era of "great security" from the era of "information security".

First, there is no unbreakable network in the world.

The first challenge faced by network security work is that network security defense is becoming more and more difficult, because loopholes are everywhere. Today, our whole society runs on software. Software is compiled by people, people make mistakes, and loopholes are inevitable.

Second, people are the weakest link in network security protection.

In addition to the vulnerabilities of network software itself, another starting point of network attacks is people. Of course, there is also a situation where insiders steal secrets or contractors take the initiative to steal information or sabotage, which is even more difficult to prevent.

Third, the core technology in the information field is subject to people.

Whether it is hardware, software or network security, the key factor in the information field is the core technology. Zhou believes that the core technology in the information field is controlled by people, just like building a house on someone else's wall. If foreign countries cut off supply, it will bring disaster to the industry.

For example, the United States has a natural advantage in collecting data and intelligence because of its innate technological advantages in the Internet field. Other countries may have worked hard to dig a few loopholes, but the United States can easily preset back doors or loopholes in software and hardware products by using its own technological advantages, and fully implement the layout and preset of cyber warfare for other countries.

Fourth, cyber warfare is the biggest challenge.

Zhou believes that the biggest challenge in the era of great security is cyber warfare. From a global perspective, while the cyber warfare capability of the United States is far ahead, other countries are also competing to launch a cyber weapons arms race.

Therefore, Zhou believes that cyber warfare, whether military or civilian, will be an overall war and an ultra-limited war, and it is extremely urgent to comprehensively improve the offensive and defensive capabilities.
