Hearing Shen Yun's words, Instructor Zheng set his eyes on a certain position below.

As the other party of the party, Yang Dedi stood up at this time and said: "Report to the instructor, I agree with this student's challenge, and at the same time, I also agree with this student's opinion. I am a network command and engineering background of the National Defense Science and Technology University, I heard that you are good at hacker attack and defense, why don't you attack me and defend me, let's have fun? ”

I have to say that Yang Dedi is indeed exquisite.

No, in front of so many people, it was actually said that Shen Yun challenged him. And by the way, Shen Yun was labeled as a self-proclaimed hacker attack and defense. At this moment, Shen Yun can't agree or not.

Shen Yun knew very well in his heart that the discipline of network and electronic command and engineering of the National Defense University of Science and Technology is in the direction of electronic countermeasures technology and command. In terms of technology, this captain named Yang Dedi is definitely not low.

But so what?

Omizuki's computer applications are not dry either. Moreover, Shen Yun himself has a lot of time and experience, and in the face of Yang Dedi's provocation, he is really true.

I wanted to keep a low profile, but it seems that it won't work. The pride that rose in Shen Yun's heart made him readily agree to Yang Dedi's provocation.

"Okay."

Yang Dedi, who didn't know Shen Yun's background at all, thought that he had taken a big advantage. At present, all the computers in this computer room are equipped with the Kylin operating system developed in China. For this system, Yang Dedi is very familiar with it.

Because this system was developed by the National Defense University of Science and Technology.

Yang Dedi is familiar with the various parameters of this system. In his opinion, even if Shen Yun is familiar with general hacker attack and defense techniques, he still has to be blind to this system.

However, what he never expected was that although the Kirin operating system has not yet been open sourced, Shen Yun's teacher is Professor Xu. When the National Defense University of Science and Technology developed this system, it specially invited this old man to participate.

The private goods that Shen Yun learned from Professor Xu are not just simple code. Even the overall idea and programming algorithm of programming at the beginning, Shen Yun learned it with it.

Although a few years have passed, the system has also added a lot of patches. But for a whole year, Shen Yun did not turn himself into a simple-minded guy with well-developed limbs. Everything about this operating system, he stared at it secretly.

He didn't expect Shen Yun to be so happy at all, Yang Dedi was stunned for a moment, and then walked forward with a smile.

"The computer I'm sitting on has some of my personal stuff on it. Don't take advantage of you, let's sit at the left and right ends of the first row. First I defend you to attack, then I attack you to defend, and the time limit for each game is half an hour. How about Coach Zheng being the referee? ”

Looking at Yang Dedi with a relaxed face, Shen Yun nodded: "Okay." ”

Instructor Zheng originally wanted to say something, but seeing that the two of them were communicating so happily, he also understood what was going on. The spirit of the boy is put on anyone. The Academy is not opposed to such protests, on the contrary, it encourages them.

Without confrontation, there is no shortcoming. This is a big no-no for technicians.

"Okay, now you two are seated. Rest of you, please sit in the back four rows of the room, and I'll transfer the screen of the two confrontations to your computer. Remember, it's okay to see, it's strictly forbidden to make any sound. ”

It is rare that two students who seem to have a good level choose to fight, and Instructor Zheng also wants others to see the charm of network attack and defense. After driving everyone to a fixed position and operating on the main console a few times, the onlookers found that two patterns appeared on the screen in front of them.

Shen Yun and Yang Dedi turned on at the same time, and then the two began to optimize their computers at the same time.

Rushing to operate without understanding the performance of the computer is a mistake for people like Shen Yun. Hacker attacks are not only about hacking into the other party's computer, but also about ensuring that their IP is not discovered.

Shen Yun first checked the computer parameters, then opened the computer settings and issued commands continuously.

Then, the other students were surprised to find that Yang Dedi installed security software on his computer through the network cloud disk. Close a lot of processes and backdoors at the same time.

But Shen Yun couldn't understand what he did at all, only to see a black dialog box, constantly jumping code, that kind of calculation speed, his eyes were about to be unable to use it.

At this time, only Instructor Zheng understood what Shen Yun was doing, but during the confrontation between the two, he was silent, and just set the recording parameters of the monitoring station.

After five minutes, Yang Dedi finally removed his hand from the keyboard. His preparations have been completed. At this time, looking up at Shen Yun in the distance, who was still crackling and constantly tapping on the keyboard, a contemptuous color appeared on Yang Dedi's face.

In his opinion, his address has not been found within five minutes, and a hacker like Shen Yun is simply a rookie.

Perhaps, Shen Yun's so-called hacker attack and defense is to download a scanning tool on the Internet at random, and then follow the tutorial step by step to scan and invade other people's computers. This kind of foolish thing is actually worthy of being called hacker attack and defense

At this time, Teacher Zheng, who was standing on the podium and looking at the console, was shocked in his heart.

The penetration difficulty of the Kirin operating system is really higher than that of the United States system.

First of all, this thing is still for the military, and it is not open source. And there is no automatic check and automatic release in this operating system, although a large part of the performance is sacrificed, but the vulnerabilities can be said to be very few.

But what Shen Yun is doing at this time is to further block the loopholes of the system on this basis. There are some places that even Teacher Zheng didn't know before.

And after doing this, Shen Yun began to act slowly.

The first thing he did was launch an attack on the console. Although Instructor Zheng was silent, the words displayed on the screen made him start to look up at Shen Yun non-stop.

"Instructor Zheng, lend me the console."

As if sensing Instructor Zheng's gaze, Shen Yun also raised his head, smiled at him, and then buried his head in tapping on the keyboard again.

A minute later, the onlookers suddenly saw that three short words appeared on Yang Dedi's screen: "You lost." ”

And the various protection software installed by Yang Dedi before didn't even have a hint.

Shocked, Yang Dedi hurriedly flipped through the operation log, only to find that there was nothing else in it except for a record that deleted the previous running project. In other words, he didn't even know how Shen Yun invaded now.

When he wanted to remove these three words from the screen, Yang Dedi found that he couldn't do it no matter what. The words stuck to the screen like kraft candy.

Instructor Zheng's voice sounded at the right time: "In the first game, Shen Yun won. ”
