Strengthening and Upgrading the Opening God-level Options

When Ye Xuan walked into the room, he saw a row of bookshelves. There were many books on it, most of which were related to computers.

Soon Ye Xuan was attracted by a book "Hacker", he picked up the book and started to read it slowly.

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

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

"Ding! Trigger the intermediate memory ability."

"Ding! Storing the knowledge I read..."

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

This "Hacker" is about cyber attacks, and the knowledge involved in it is very extensive and advanced. If you don't have professional basic knowledge, you can't understand what it's talking about.

At present, there are two most popular network attack methods, one is ddos ​​attack, and the other is dos attack.

Dos attacks generally adopt a one-to-one method. When the attacked target has low CPU speed, small memory or small network bandwidth, etc., the performance indicators are not high, and its effect is obvious.

With the development of computer and network technology, the processing power of the computer has increased rapidly, the memory has increased greatly, and a gigabit network has also appeared at the same time, which makes the dos attack more difficult - the target's ability to "digest" malicious attack packets "It has been strengthened a lot. 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 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 victims on a larger scale than before.

This time, Ye Xuan was not flipping through the books fast. His brain was running fast, understanding and absorbing the knowledge he saw. At this time, he seemed to have discovered a new continent.

Today is the era of rapid network development, so there will be different levels of network attacks every day, and network warfare is a war without gunpowder.

Satellites, navigation, aircraft, missiles and other operations all need access to the network. Once the network is destroyed or controlled by the enemy, one can imagine how terrible the consequences will be. Therefore, every country attaches great importance to network security.

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

"Ding! Photographic memory ability +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 imagined.

"Ye Xuan, how are you? Did you gain anything?" Zhang Ming walked in at this moment, and asked when he saw Ye Xuan.

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

"Yes, so don't underestimate the computer. Under the control of an expert, the damage caused by this computer is very terrifying. Come, let me show you some content." Zhang Ming turned on his computer after speaking.

A video was played. This was a duel between hackers. The two parties used a large number of junk data packets to attack each other. Many financial companies, educational institutions, and medical institutions were violated to varying degrees, causing considerable damage. Loss.

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

"Mr. Zhang, what if someone attacks our country's network?" Ye Xuan asked subconsciously.

Zhang Ming smiled slightly and said: "Our country's network is attacked every year. There are two major organizations in our country. One is the network security team of the Ministry of National Defense. There are many experts in it. They will resist attacks from outsiders and protect our country. network security."

"The other is the non-governmental organization Hongke Alliance. The people here are also very powerful. They belong to different companies, but they all have the same belief, that is, those who offend China will be punished no matter how far away they are!"

"The purpose of the Honker Alliance is to protect the security of Huaguo's network, so our country's network has always been very safe under the protection of the two major organizations."

"Those who offend China will be punished no matter how far away they are!" Ye Xuan muttered to himself, and hearing these words made his blood boil a little.

"Ye Xuan, if you want to know more, you can go to the Honker Alliance Forum. There are not only various histories, but also technical exchanges."

"When I'm free, I usually go up there to see if there are any news or technical exchanges. If you have confidence in your own strength, you should contact the person in charge of the forum for an assessment. If you pass the assessment, you You can join the Honker League." Zhang Ming smiled lightly.

"That's it, then it seems that I have to take a look at the Honker League forum if I have time. By the way, Mr. Zhang, have you joined the Honker League?" Ye Xuan asked.

"Uh, this..." Zhang Ming blushed and became a little embarrassed.

Zhang Ming had already participated in several assessments of the Honker League, but failed all of them. He was somewhat embarrassed when asked by Ye Xuan suddenly.

"Haha, to be honest, the teacher didn't join the Honker League. It doesn't mean that the teacher is not strong enough, but that the teacher simply doesn't have time."

"You see, in addition to class, the teacher also has to repair the school and some of his clients' computers, so how can he have this time?"

"It's true, the teacher is so busy, how can he be free? If the teacher wants to join the Honker League, it will be a matter of minutes." Ye Xuan said with a smile. Of course he could tell that Zhang Ming was lying, but he See through but not tell.

"That's right, that's right. If the teacher has time, he will definitely participate in the assessment of the Honker League. Joining the Honker League will not be a problem." Zhang Ming said with a smile.

"Mr. Zhang, then I'll read other books, you go ahead first," Ye Xuan said.

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

"Okay." Ye Xuan responded, then took a book from the bookshelf and read it slowly.

Seeing Ye Xuan sitting on a chair reading a book, Zhang Ming also breathed a sigh of relief. Fortunately, he reacted quickly enough, otherwise he would really be ashamed.

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

Moreover, 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 became more and more interested the more he watched, he felt that some things that cannot be realized in reality can be achieved in the online world.
