Chapter 352： another world

Ye Xuan walked into the room and saw a row of bookshelves with many books on it, most of them related to computers.

Soon Ye Xuan was fascinated by a "hacker" book, he picked up the book and slowly read it.

"Ding! The host reads "Hacker", computer programming ability +1..."

"Ding! The host reads "Hacker", computer programming ability +1..."

"Ding! Trigger the intermediate ability to remember."

"Ding! The knowledge you are turning over is being stored..."

As Ye Xuan flipped through the books, the computer programming ability continued to strengthen, and all the knowledge he saw was stored in his brain. Once the ability was triggered, the computer knowledge would immediately appear in his mind.

This "hacker" is about the content of cyberattacks. The knowledge involved is very extensive and advanced. If you don't have professional basic knowledge, you can't understand what it says.

There are currently two most popular network attack methods, one is ddos ​​attack, and the other is dos attack.

Dos attacks are generally adopted one-to-one. When the target CPU speed, low memory or network bandwidth is low, the performance indicators are not high, its effect is obvious.

With the development of computer and network technology, the processing power of computers has increased rapidly, and memory has increased greatly. At the same time, gigabit networks have appeared, which makes the difficulty of DOS attacks increase-the target’s ability to digest malicious attacks "A lot of enhancements, for example, your attack software can send 3,000 attack packets per second, but my host and network bandwidth can handle 10,000 attack packets per second, so that the attack will have no effect.

At this time, ddos ​​came into being, which is to use more puppet machines to launch attacks and attack the victims on a larger scale than before.

This time Ye Xuan wasn't reading books fast. His brain was running fast, understanding and absorbing the knowledge he saw. At this time, he was just like discovering the new continent.

Today is the era of rapid network development, so there are different levels of cyber attacks every day. Cyber ​​warfare is a war without smoke.

Satellite, navigation, aircraft, missile and other operations all need to go to the network. Once the network is destroyed or controlled by the enemy, the consequences can be imagined how terrible, so every country attaches great importance to network security.

"Ding! Computer programming ability+1..."

"Ding! Do not forget the ability to +1..."

Time passed little by little. When Ye Xuan finished reading this book, he was very shocked. The cyber war was far more terrifying than he thought.

"Ye Xuan, how is it, is there any gain?" At this time, Zhang Ming came in and asked Ye Xuan when he saw Ye Xuan.

"Mr. Zhang, I didn't expect this cyber war to be terrifying. One command attack can cause such a large loss." Ye Xuan sighed with emotion.

"Yeah, so don't underestimate the computer. Under the control of a master, the damage caused by this computer is very terrifying. Come, let me show you some content." Zhang Ming opened his computer after finishing talking.

A video was broadcast. This was a duel between hackers. The two sides used a lot of junk data packets to attack each other. Many financial companies, educational institutions, medical institutions, etc. have been violated to varying degrees, causing a lot of Loss.

The entire video was only a few minutes, but the content inside shocked Ye Xuan.

"Teacher Zhang, what if someone attacks our network?" Ye Xuan asked subconsciously.

Zhang Ming smiled slightly and said, "Our country’s networks are attacked every year. There are two major organizations in our country. One is the Ministry of Defense’s Cyber ​​Security Group. There are a lot of experts in it. They will resist attacks from outsiders and protect our country. Network security."

"The other is the non-governmental organization Hongke Union. The people inside are also very powerful. They belong to different companies, but they all share the same belief, that is, those who offend China are far from being punished!"

"The purpose of the Hongke Alliance is to protect the network security of China. Therefore, my country's network has always been very safe under the protection of two major organizations."

"Although those who offend China are far from being punished!" Ye Xuan murmured to himself, and he heard that he was a little bit bloody.

"Ye Xuan, if you want to learn more, you can take a look at the Hongke Alliance Forum, which not only has a variety of history, but also technical exchanges."

"I usually go to take a look when I have time to see if there are any news or technical exchange posts. If you have confidence in your own strength, you can contact the forum person in charge for the assessment. If the assessment passes, you You can join the red guest alliance." Zhang Ming chuckled lightly.

"Well, then it seems that I have time to look at this red guest alliance forum. By the way, teacher Zhang, have you joined the red guest alliance?" Ye Xuan asked.

"Well, this..." Zhang Ming blushed a little, embarrassed.

Zhang Ming has participated in the assessment of the Red Guest Alliance several times, but all failed. At this time, Ye Xuan suddenly asked him that he was somewhat embarrassed.

"Haha, to tell the truth that the teacher did not join the red guest alliance, it is not that the teacher is not strong enough, but that the teacher has no time at all."

"You see that in addition to the class, the teacher has to repair the computer of the school and some of his customers, so how can there be this time."

"It's also true that the teacher is so busy. If the teacher wants to join the red guest league, it's a matter of minutes." Ye Xuan said with a smile, of course he could hear Zhang Ming lying, but he See through, don't talk through.

"Yes, yes, that's it. If the teacher has time, then he will definitely participate in the assessment of the Hongke Union, and joining the Hongke Union is not a problem." Zhang Ming said with a smile.

"Teacher Zhang, then I will read other books, you are busy first." Ye Xuan said.

"Yes, you can read the books here by the teacher. You can come over if you have time. In addition to reading, the teacher will teach you some advanced knowledge and technology." Zhang Ming said with a smile.

"Okay." Ye Xuanying made a sound, then took a book from the shelf and looked at it slowly.

Zhang Ming saw Ye Xuan sitting in a chair reading a book, he was relieved in his heart, but fortunately he reacted fast enough, otherwise he was really embarrassed.

Ye Xuan found that this network is also very interesting, this is a virtual world, you can do many things in this virtual world.

And the network is applied to all aspects of real life, so this network belongs to the second world, and every country attaches great importance to network construction and network security.

Ye Xuan is more and more interested. He feels that some things that cannot be achieved in reality can be done in the online world.
