Xueba's Black Technology Simulator

Lu Xiao returned to his company, and Peng Zhihui was still working here!

Originally, Lu Xiao thought that Peng Zhihui would look for another job, but he did not tell Peng Zhihui the situation during the three months of retreat, and he did not call alone to ask where Peng Zhihui was a few days ago.

Unexpectedly, Mr. Zhihui has been working conscientiously in the company.

Lu Xiao's office is protected by brother b, because the server inside has important software.

Peng Zhihui also had the key. After Lu Xiao disappeared, he finished his school affairs and went back to work in the company. The company website had already been written, and he went to work to learn about artificial intelligence and robots.

Everything else is good, and the computer is still top-of-the-line. What makes him a little upset is that he has to be strictly checked every time he goes to work.

And of Lu Xiao's three servers, only one was reserved for Peng Zhihui to use, and the other Lu Xiao's server, and the other server storing the company's website, were not open to Peng Zhihui.

He can't upload the website, so he can only test it on his own server. When Lu Xiao comes back, he can launch Xiawei's official website.

Lu Xiao and Peng Zhihui greeted each other, and then listened to the bodyguard's introduction.

Because of Xiawei Technology, a few newcomers came.

Wang Meng introduced: "These two are the security guards in charge of protecting the company. They are named Liu Qing and Liu Bai. They are both retired soldiers. They will be responsible for the company's security in the future. If you still want people, tell them how many people you want. "

"This is Li Han, who is in charge of computer security. He also lives in the company and guards several servers."

The rest is Peng Zhihui, no introduction from Wang Meng is needed.

Peng Zhihui felt aggrieved and said, "My website is finished, but he won't let me use the server!"

Good guy, report when you meet.

He even told them in front of others that Mr. Zhihui's EQ might be a bit low.

Lu Xiao laughed, waved his hands and said, "Okay, okay, I'll arrange it. Li Han's company's server can be used by Peng Zhihui in the future. You should have reviewed it, and Peng Zhihui can believe it."

Hearing this, Peng Zhihui raised his head and winked at Li Han.

Lu Xiao didn't care about them, took out the USB flash drive when he entered the work station, reinstalled the software he wrote these days on the server that was disconnected from the network, and upgraded the server's firewall.

This is the firewall modified by Lu Xiao himself. Apart from the suitcase and notebook he carries now, it is Party j's own system.

The desktop is still a Microsoft system, so Lu Xiao put the software into the desktop again, and installed a super firewall simulated by a 50gb database.

Seeing Lu Xiao's operation, Li Han reminded: "Boss, is this unsafe?"

"The server is not connected to the Internet. It's not a big problem. I will upgrade it later. Now my desktop computer needs to be connected to the Internet. Let computer experts attack." Lu Xiao smiled.

Only then did Li Han know that Lu Xiao was about to face the computer security test and assessment arranged by his superiors.

Lu Xiao made a phone call, and soon Chen Yang began to let computer experts attack Lu Xiao's IP address.

During the whole process, Lu Xiao could not touch the computer, nor could he take defensive actions.

This is simulating the real situation.

After the software is uploaded to the cloud in the future, although there will be people guarding the supercomputer, it is also necessary to prevent the absence of people.

In a computer laboratory in Beijing, countless computer experts are attacking Lu Xiao's desktop computer.

Among them, a young man with glasses said confidently to Chen Yang: "Lu Xiao is still using the Microsoft system. We know many loopholes in the Microsoft system. These loopholes are not disclosed. Lu Xiao must not know. Wait a few minutes and we will be able to break through Lu. Akatsuki's computer!"

Chen Yang nodded and said, "Come on, if you fail, it will be a shame."

Not long after, a young man in a slovenly plaid shirt said in surprise: "The system seems to have been upgraded by Lu Xiao, and the few loopholes we found are useless!"

"It's strange, there's no way to get the computer's super privileges by chance, we can't even get in, this firewall is so powerful." Another person said.

The boy with glasses looked at Chen Yang in embarrassment. Seeing that his expression was still serious, he rolled up his sleeves and prepared to operate it himself.

Not long after, cold sweat broke out on his forehead.

I thought the other party was a novice, but he actually used the most common Microsoft system. You must know that a slightly powerful computer expert or hacker doesn't like the Microsoft system at all.

Everyone uses Linux, and many experts modify the system by themselves.

After seeing that the ip reported by Lu Xiao was using the Microsoft system, he was a little contemptuous.

It wasn't until now that I realized something was wrong!

The opposite side is pretending to be a pig and eating a tiger, deliberately showing weakness to the enemy, but in fact he is a master.

The rubbish things like the Microsoft system have been fully armed.

The boy with glasses sweated more and more on his forehead, and said with difficulty: "Secretary Chen, the conventional means of intrusion have failed, at least the few system loopholes we have mastered cannot overcome this computer, there is a very powerful firewall, now We can only try to launch a data flood attack!"

Because Chen Yang is not a computer major, the boy with glasses specially used a word he can understand to describe it.

The so-called data flood is actually a DOS attack.

The purpose is to use a large amount of useless data to impact the broadband network and exhaust the computing resources of the attacked object.

Soon the glasses boy heaved a sigh of relief, this time he did not fail.

Seeing this, Chen Yang asked in confusion: "Have you obtained the software information in the other party's computer?"

"Um, no, we can't get into his computer." The glasses boy said awkwardly.

"But he can no longer access the Internet. We have squeezed out all the network resources, so he can only stop the service."

Chen Yang shook his head and said: "It's useless, what I need is to break into his computer and get the information inside!"

"That can't be helped, the defense is too strong. Didn't Secretary Chen say that the software will be placed on the server in the future? Then you ask him to give us a port for remote operation of the software. Let's check the loopholes in the software and see if it works from this aspect." " said the boy with glasses.

Lu Xiao received a call to open the port for computer experts to access.

He smiled and shook his head, feeling more calm in his heart.

You know, his software uses a more powerful encryption system.

It is 100% progress obtained by spending 9 simulation points, dedicated encryption!

The firewall is just data extracted from 50gb of data, and even this cannot be broken, let alone software.

Now it is equivalent to Lu Xiao passing on the client side that is open to customers in the future when it is commercially available in the capital.

Of course, this client is actually a web browser.

All the data is sent to Lu Xiao, and after Lu Xiao finishes processing, it is sent back to the client port.

For example, if you want to use ultrasonic automatic modeling software, the ultrasonic data is first transmitted to Lu Xiao’s computer, and then the results are sent to the controller after calculation.

These data are meaningless, what is important is how to calculate this data.

Chen Yang called back in four hours, congratulating Lu Xiao and said: "The test passed. They said that your software is very safe, and they can't find a way to crack it. They even used a supercomputer just now, but it still didn't work."

"But they are not reconciled, saying that they will continue to try to obtain software information in the future. I agree with their tentative attacks in the future. If they find a way one day, then your civil rights will also need to be given up."

Lu Xiao smiled and said: "No problem, but don't use DOS attack this way, it will only cause me to be disconnected from the Internet, and they will not get valid information. Let them try to crack my software in the future."

Next, Chen Yang discussed with Lu Xiao how to open the civil service.

First of all, the software can only be placed on the j party server, and Lu Xiao's company only has data access rights.

It is equivalent to collecting data every time, and finally handing over the data to the server managed by party j for calculation, and finally passing it to the terminal that Lu Xiao wants to sell.

Originally, Chen Yang wanted to propose a method of direct physical isolation, such as manually transporting data each time, but because Lu Xiao proved that it is difficult to obtain confidential data from the Internet, he did not mention this plan.

And if there is a physical isolation, it will be very troublesome for Lu Xiao's business.

The most important thing is to calculate data in real time. Isn't physical transportation similar to genetic testing?

Get the gene first, and it will take a long time to produce results.

There is still a lot of work in the future, such as upgrading the server firewall, facing the probing attacks of computer experts again, and so on.

This is all something later, Lu Xiao can now call Mr. Peng's teacher and dig Peng Fangcun to Rongcheng Company to carry out follow-up research.

The matter of poaching people went smoothly. Lu Xiao just called the old academician, and the other party said that there was absolutely no problem.

As a result, half an hour later, Peng Fangcun called and asked Lu Xiao to receive him.

Peng Fangcun is an old bachelor. He devoted his entire life to the Northwest Secret Base, so he came here very simply, without dragging his family along.

The place to live is also easy to solve, or live in the company like the two security guards and Li Han.

It is also convenient to protect.

In addition, Lu Xiao also chatted with Peng Zhihui and asked him if he would like to follow Mr. Peng to study the effects of ultrasound on plants and animals.

There is also the subject of commercializing ultrasonic automated imaging.

Peng Zhihui shook his head without hesitation: "I like to study things related to ai, machinery and robots. What you are talking about is not the direction I am interested in."

Lu Xiao still wanted to keep Peng Zhihui, so he said: "In the future, there will definitely be opportunities to study robots and intelligent machines, so please help Mr. Peng for the time being. You have also seen the crop circles and bamboo forest circles we made last time. If this technology is improved, it can be used to accelerate the growth of plants, think about it, in the future, because of your efforts, we will increase the grain production of our country in Xia!"

"How fulfilling is this? Isn't it better than when you study robots?"

"In addition, you can integrate robots into agricultural production. For example, you can study a puppy-like robot. Every day it goes to the farmland and automatically barks at the plants, and then the plants increase production. Isn't it very interesting? significance?"

Peng Zhihui opened his mouth wide, he didn't expect that Lu Xiao's technique could be used like this.

"Is this really possible?" Peng Zhihui asked in surprise.

"Yes, absolutely. I will be responsible for the sound wave parameters. You can design a robot with multi-functional terrain operations in the future. Of course, the premise is to install the ultrasonic equipment, and then it is possible to realize the picture I mentioned." Lu Xiao is very sure. Said.

In the future, Peng Fang will be saved to do basic design work.

Lu Xiao is still responsible for the most critical sound wave parameters, which involves confidentiality issues.

In fact, Lu Xiao just lacked the people to do these basic tasks.

For example, what kind of machine is designed for the police, whether it is portable or vehicle-mounted, this is the job of Peng Fangcun and the others.

How to calculate the sound wave parameters is done by the cloud server.

Peng Zhihui was persuaded in the end, for him, Lu Xiao's company is still very good.

The salary is also very high, and you can learn something.

It's just that the work inspection is a little stricter.

But really doing practical things is a major event for the country and the people.

Following Lu Xiao and seeing big scenes at Rongfei Group Airport, Peng Zhihui also has a lot of family and country feelings.

In fact, he also guessed in his heart that the black dragon that appeared three months ago was related to Lu Xiao.

Because the time when Lu Xiao disappeared coincided with the time when the black dragon and space-based weapons appeared.

Of course, he won't tell anyone about these things, although sometimes his emotional intelligence is not very high, but that's just intentional.

A person with a high IQ is really willing to spend a little time thinking about it, how could they not have a high EQ.
