Next, Fan visited another laboratory. It is also the focus of the laboratory system of the entire Southeast Heavy Industry, the computer network defense project laboratory.

Compared to the other labs, the situation in the Computer Network Defense Project Lab is different, and it is all about young technicians who are in charge of the overall situation.

When Fan Wuzhi came over, he saw that most of them were staff in their early twenties, the oldest of whom were only a few doctoral students in their early thirties, and a few experts from the Institute of Computing Science of the Chinese Academy of Sciences.

Fan Wuxian is still more interested in this part of the business, after all, he obviously knows a lot more about computers than any radar array and fire control system, and he is also more clear about the development of some general directions.

And in terms of the atmosphere of the staff, this lab is also much more active.

It seems that Fan Wuxian himself has a very good impression among young employees, especially young employees engaged in the computer industry, whether it is the wealth effect or the revitalization of the national industry has always been the goal of young people.

Subsequently, Fan Wuxian learned in detail about the various goals and progress of this laboratory.

In modern warfare, computer network defense has become very important, and its application and principles are an active component of conducting computer network warfare. It is critical for all areas of warfare, mainly including computer network attacks, computer network utilization, and computer network defense.

A computer cyber attack is the use of a computer network by cyber warriors to disrupt, resist, weaken, or destroy information in enemy computers and networks, as well as the activities of the computers and networks themselves.

Computer network utilization refers to network activities that enable our side to have combat and intelligence-gathering capabilities and guide our side to use computer networks to collect data from the enemy's automated information systems and networks.

Computer network defense refers to the use of computer networks by cyber warriors to protect, monitor, analyze, detect and respond to unauthorized behavior in the computer information systems and networks of the Department of Defense.

Overall, the goal of a computer network defense strategy is to build a trustworthy information and network infrastructure. In other words, the impact of an enemy attack must be minimized, and the enemy's entry, retention, and movement must be prevented.

"To put it simply, cyber workers will implement this strategy in a complex and volatile environment, through the method of implementing defense-in-depth, forcing the adversary to break through multiple layers of defense or pass through multiple layers of defense to achieve control of the network, thereby reducing its probability of success. Based on the principle of strong information assurance, the computer network defense strategy relies on the effective cooperation of personnel, technology, and computer network defense. A lab supervisor explained to Fan Wuxi.

Fan Wuxian nodded, knowing that the progress in this area in China is much slower, after all, the digital change of equipment in the whole army is far from being reached, and the penetration rate of computers needs to be further improved.

However, this work is also very important, and we must not start it in advance, otherwise it will be a big trouble after we really change our outfits and make full use of digital combat equipment or digital command system; after all, a complete set of digital command and decision-making systems with complete contents and powerful functions cannot be developed in a moment and a half.

This work requires not only design in the laboratory, but also practical testing, as well as a reservation of module interfaces that can be continuously developed. So it's not something that can be done in a short period of time.

The main service content of computer network defense is to protect, monitor, analyze, detect and respond to network attacks, and these services refer to the combat operations carried out in order to prevent or weaken network attacks that may lead to computer network interruption, denial of access, degradation, collapse, computer network and information system intrusion, and information theft.

In order to develop a domestic computer network defense system, the laboratory is carrying out some initial work, first of all, it is necessary to collect, correlate, fuse, analyze, display, and publish data from various channels, create a set of powerful and comprehensive comprehensive command and combat systems, and constantly expand its functions.

In this case, it includes not only host security systems, but also malicious adware and spyware detection, removal, and protection systems, relying on the active defense capabilities of host-based security systems to achieve defense purposes.

One important way to do this is to strengthen the protection between internal and external networks, and the researchers say they are now working with the Security Agency and the Department of Defense Information to strengthen information assurance strategies when exchanging information between internal and external networks. While protecting the internal network from external cyber attacks, the use of public information by untrusted external resources is restricted.

There is also the ability to monitor the network and activity in the system by running an intrusion protection system, looking for malicious and unwanted network behavior, and allowing cyber defenders to take decisive action in real time to stop or prevent it.

With intelligent agent security management, security event logs and alerts from primary sensors, firewalls, routers, and operating systems can be acquired and normalized in near real-time, completing the analysis of standardized, attribution-based events. and evaluate anomalous events that raise alerts for specific security attacks. Intelligent agent security management monitors communications in a network and determines whether it is a misoperation, spoofing, or cyberattack based on a variety of criteria. It collects, normalizes, correlates and analyzes data to provide a real-time snapshot of cyberattacks.

In order to overcome the weaknesses of the software public key infrastructure, they are now moving completely to the use of hardware codenames such as universal access cards, alternate codes, hardware-based external authorization codes, and hardware-based federation codes.

To improve security, reduce costs, and reduce software compatibility issues, a standardized, enterprise-class operating environment will be provided for desktops and minicomputers running the Microsoft operating system, with a common configuration developed for the enterprise rather than a variety of homegrown configurations.

"But now there are two main problems in front of us, one is the underlying core chip with independent intellectual property rights that can be used, and the other is our own operating system, if these two problems are not solved, our work is built on the sand, which is meaningless." The person in charge of the laboratory said to Fan Wuxian helplessly.

"Hmm-" Fan Wuxian nodded, indicating that it was understandable.

In fact, there is no need for them to say more, and Fan Wuxian also knows very well that these two problems have always been the big problems that plague domestic national defense construction, and if these two problems are not solved, then a lot of work will be in vain.

Most units in China use processor chips from American companies such as INTEL, and the operating systems are all like Microsoft's Windows operating system or some other operating systems, and there are many problems in these processor chips and operating systems.

THERE IS EVIDENCE THAT BOTH INTEL AND MICROSOFT HAVE BEEN SET UP BY THE US SECURITY DEPARTMENT IN THEIR PRODUCTS ON THE GROUNDS OF NATIONAL SECURITY, SO WHEN THE US MILITARY STRIKES A CERTAIN COUNTRY, IT CAN USE SOME BACKDOORS SET UP BY OTHER COUNTRIES TO CARRY OUT TARGETED CYBER ATTACKS ON THEM, SO AS TO ACHIEVE THE PURPOSE OF PARALYZING ITS COMMAND SYSTEM AND WEAPON CONTROL SYSTEM.

Although it may sound very complicated, in fact, it will be very simple in the specific operation, and only a few simple instructions need to be issued to achieve the strategic goal of surrendering the army without a fight.

Therefore, it is no exaggeration to say that it has its own core chip technology and products. It is of great significance to have a general-purpose computer operating system developed from the bottom by yourself, which is no less than building an invisible great wall of steel for yourself.

At this time, the laboratory is still making some solutions for the software and hardware architecture of INTEL and Microsoft, although the military is also using its own professional chips and operating systems, but the software and hardware equipment developed earlier is obviously too backward.

Although it has been said before that even on the space shuttle, the use of 386 chips is enough to be competent for various jobs, but in fact, with the development of the times and the progress of science and technology, people find that there will be more and more difficulties that need to be solved and faced, and there are more and more problems that need to be considered.

In this case, it is urgent to develop more high-end chip technology and software technology.

However, seeing the expressions on the faces of these young people in the laboratory, Fan Wuxian couldn't help but reveal a little news, "Regarding the issue of general core chips and operating systems, we are in development, and some underlying application products have been launched, and it is estimated that by this time next year, it should be possible to launch technical products close to the current fashion trend." ”

Then he added, "This is a product that we have built from the ground up completely on our own research and development." There is no need to worry about any backdoors, and even if there is, we will leave them ourselves. After a while, I will have people share the relevant technical information with here, so that in addition to the network defense planning for the software and hardware systems of the Americans, you can also start to work on the comprehensive design of our own software and hardware network defense systems. ”

When everyone heard the news of Fan Wuxi, they immediately boiled, and the laboratory was full of enthusiastic applause.

In fact, young people in China have always been the most distressed about not being able to provide general-purpose computer core chip products and their own operating systems, and I heard that it is expected to be realized at this time. Naturally, I can't hold back the joy in my heart.

As we all know, the CPU is the core component that determines the performance of a computer, and it is also the core of the entire system. It is responsible for the execution of instructions and the mathematical and logical operations of the whole system; storage and transmission of data; and control of internal and external inputs/outputs.

In this field of computer core components market, the two most familiar brands are undoubtedly Intel and AMD, whose strong position in the processor market seems to be unshakeable.

In terms of CPU technology, we have a large gap with foreign manufacturers, and the lack of CPU chips with independent intellectual property rights is a major core disease of China's computer industry, and it is also an eternal pain in the chest of electronic workers and network people.

In the past, CPU chips, which represent the top technology of international IT, have been monopolized by foreign giants such as Intel, and Chinese companies and consumers have paid huge copyright fees for them. Fortunately, the chip company under Fan's Investment Group has launched a series of self-developed core chips, breaking the history of China's coreless.

The birth of Fan's domestic CPU has also been praised by industry insiders as a milestone on the road of national science and technology industrialization. The successful development of the commercialized Fan's CPU also marks that it has broken the foreign monopoly and initially mastered the key technology of contemporary CPU design, and has taken an important step to change the unfavorable situation of the domestic information industry, and has played an important role in promoting the formation of a domestic computer industry with independent intellectual property rights, and has played a pivotal role in China's CPU core technology, national security, and economic development.

Especially in some commercial fields, such as the embedded chips in smart home appliances, Fan's has occupied most of the market, after all, the price advantage of low-grade general-purpose CPU chips produced in China is unmatched.

Although there are still many problems with the current domestic CPU, there are still many gaps in performance compared with the current mainstream CPU, and it cannot compete with Intel and AMD CPUs in the PC market, but frankly speaking, the situation of today's domestic core is much better than that of products such as Hanka back then.

Back then, when Fan Wuji's company made Hanka, it was hand-welded by scientific researchers with no industrial experience who were born in mainframe machines, and manually tested piece by piece.

Fan Wuxian still remembers that Fan's front-line sales staff received almost as many complaint calls and order calls every day, and for every hundred Hanka sold, there were almost ten problems, and today's domestic CPU project has not only received strong support from all sides, passed strict achievement appraisal, benchmark testing and product testing, and entered commercial production, but also received strong support from local governments and enterprises, and has established industrialization bases in Shanghai, Chongqing, Jiangsu, Guangdong and other places. And it is used in domestic home appliances, replacing a large number of foreign general-purpose chips.

And there is also news recently that the Chinese Academy of Sciences is also engaged in a Loongson project. China is paying more and more attention to the research work in this area.

There are no pop-ups
