Who will solve our network security problems? Obviously, the questions raised by Wang Zhengyu's opening remarks are a bit big, which makes the emotions of the people on the scene polarized, either sneering at them, or looking forward to the next content.

However, Wang Zhengyu ignored these things and did not give the answer directly. Instead, he began to operate on the notebook.

"This is an ordinary Lenovo laptop with a win7 operating system pre-installed on it, and it is a win7 system that has not been installed with any Microsoft patches." Wang Zhengyu operated the computer and showed the entire system situation to everyone in front of the audience through the big screen behind it.

"Now this computer is connected to the public wife provided by Qiandu without any security measures. Let's take a look. The IP assigned by the route is 192.168.1.187. I think in the eyes of hackers who know a little bit of intrusion technology, this is a perfect broiler. There is no password, no security software, and I haven't even applied the patch provided by Microsoft for half a year. I even announced the IP address! So is this really the case?"

Wang Zhengyu raised a question again, but this time he did not leave time for everyone in the audience to think, but said loudly: "Now, please Mr. Qian Xiaohua, the vice president of the Huaxia Software Association, who is sitting in the audience, and the chief engineer of the Second Research Office of the Huaxia Electronic Information Industry Department, to give you a live demonstration!"

After saying that, Wang Zhengyu took the lead in applauding.

This was the part that had been discussed at this press conference, so Qian Xiaohua naturally would not refuse. He walked onto the rostrum with applause.

"These are all people here today. When I came here, I took a look at it casually. Eighty-most of them were familiar faces, so I didn't say much nonsense. I started directly!" Qian Xiaohua smiled and said a few words to the audience, then walked directly to another projector on the stage. A computer that had been prepared was placed there, and the large screen behind it was immediately divided into two, showing the display screens of both computers.

"You can see that this computer has two most commonly used scanning and intrusion software for Chinese hackers, and there is also a hacker software developed by our research team specifically for testing system security. Now, I have begun to invade the computer opposite in a conventional intrusion method!"

Then Qian Xiaohua began to operate tediously. While operating, Qian Xiaohua was still explaining the ideas of intrusion, including exploiting system vulnerabilities, software vulnerabilities, router vulnerabilities, etc.... This was just repeated in his laboratory, Liu Hongwei's failed operations, so these attempts were undoubtedly all failed.

In fact, when Qian Xiaohua was unable to successfully invade through two methods, people who knew the industry in the audience had already started to discuss it. Many people who had specially brought computer equipment had already started invading themselves in the audience. Of course, the result was imagined.

Half an hour later, after trying all the methods but failing to invade successfully, Qian Xiaohua stopped the action in his hand and said, "Everyone has seen it. According to the principle, an experienced hacker can fully control it in just a few minutes, but I used all the methods but could never invade this host. In fact, from my operation data, you can see that when I tried to invade this host, many colleagues in the audience were also trying it, and everyone could see the result!"

After saying this, Qian Xiaohua paused and continued: "In fact, what I did today is something I have proved in our laboratory, and we even did more in the laboratory than we are now. We even implanted Trojans on win7, but we still couldn't successfully invade this computer. As for why this happens, Mr. Wang Zhengyu will continue to explain it to you now."

Qian Xiaohua's words fell and there was an uproar in the audience.

As Qian Xiaohua said, most of the people in the industry today were successful people. They naturally knew Qian Xiaohua's weight in the industry, and were even more puzzled by the results of the intrusion demonstration on the spot. Why did a new system come up with a win7 system without any security measures? But this system with vulnerabilities can prevent the intrusion of a top programmer? At this time, everyone's eyes were focused on Wang Zhengyu.

"Thank you, Mr. Qian!" Wang Zhengyu thanked Qian Xiaohua, then pressed his laptop twice and switched to the operating interface of the Dragon Shield system. At this time, after being modified by Qiandu Artist, in addition to a few buttons, there was also a coiled shield-shaped five-clawed golden dragon.

"This is the Dragon Shield operating system developed by our Tianshu Technology! You can see that this system itself does not have any applications installed, and it cannot support any applications, but it can support other operating systems to run barrier-free on this system. Of course, it is not only supported by the Windows series system, but UNIX system can be installed on this system at the same time, and the two systems can also be switched at any time."

Wang Zhengyu installed a UNIX system that had been prepared on this laptop at the same time. After the installation was completed, a UNIX system icon was added to the operating interface of the Dragon Shield system. Double-click to enter, and the UNIX operation interface was displayed on the large screen behind it.

"Of course, this is not limited to Windows and UNIX. You can also install another Windows system, and they can also switch between them at any time." Wang Zhengyu said, and his hands were constantly moving. Another win7 was installed on this computer. Then Wang Zhengyu began to switch between the three systems back and forth.

After demonstrating this function of the Dragon Shield system, Wang Zhengyu continued to speak: "This Dragon Shield system is an operating system specially designed for network security, but its function is definitely not only reflected in its security, but also in the convenience it is shown now. In fact, after installing our Dragon Shield system, the efficiency of other operating systems during operation can also be greatly improved. Now I want to hire Qiangong again to conduct professional tests for us on site!"

After Wang Zhengyu finished speaking, he bowed to Qian Xiaohua again.

"Okay, in fact, this is also the conclusion we have tested in the laboratory. In order to show it more intuitively to everyone, we specially prepared a laptop that is exactly the same, and also uses the win7 operating system to do professional testing for everyone here!"

After Qian Xiaohua finished speaking, the staff brought a Lenovo laptop that was exactly the same as Wang Zhengyu.

"First, let's look at the working status of the CPU after the two computers run the same software."

Qian Xiaohua started running a large-scale test software similar to 3DMAX on two laptops at the same time, without even testing professional software, and could tell the advantages and disadvantages of the two computers when running with the naked eye.

Then there was a series of tests. Qian Xiaohua finally announced: "You can see that based on the results obtained by all data, after installing the Dragon Shield operating system, the operating efficiency of the win7 system has increased by 38%, which is something that no optimization software can achieve at present."

"Finally, I want to say more is that this Dragon Shield system is not much the same as other operating systems we have been in contact with in the past. Although it requires other operating systems to support applications, it does not prevent it from becoming a great system! At least, it is definitely the safest system now!"

After saying that, Qian Xiaohua nodded at Wang Zhengyu, then walked directly to the audience, leaving the entire rostrum to Wang Zhengyu alone.

There was an uproar in the audience.

At this time of the press conference, everyone had roughly understood what kind of operating system Longdun was, and were also amazed at the performance of this system.

Whether it is its security or optimization of other operating systems, it proves its excellence. More importantly, it is very convenient to use. After watching Wang Zhengyu's demonstration, it only requires a system backup to generate a brand new operating system under this system at any time.

How convenient this is! In the future, one computer, one system is used for work, and the other is used for entertainment. The two can be switched at any time without barriers. All you need is to press a set of shortcut keys and click it twice with the mouse.

Of course, it is its weakness that cannot support applications. However, if Longdun is not regarded as an operating system, this pair is an extremely excellent software. Perspective industry insiders can naturally see the potential market value of this system.

Especially since this system is the same company as the developer of the voice-controlled smart housekeeper, the commercial gimmicks contained in it are enough to make countless people imagine.

Those media people who don’t know much about the operating system can conclude from the introduction of this press conference that after using the Dragon Shield, the system can be faster, more convenient and safest.

"Okay, thank you Qian Gong again!" Wang Zhengyu bowed slightly to Qian Xiaohua's location, and then continued: "Today, the Dragon Shield System developed by our Tianshu Technology has been introduced to you. Of course, there may be people at the scene who are suspected that we colluded with Qian Gong today and made a double act, right?"

Wang Zhengyu's words caused a kind laugh from the audience. As long as he was an insider, he naturally knew that with Qian Xiaohua's identity, he would never be able to do such despicable things.
Chapter completed!
