Ye Xuan walked into the room and saw a row of bookshelves with many books on them, most of which were related to computers.
Soon Ye Xuan was attracted by a book on "Hackers". He picked up the book and started reading it slowly.
"Ding! The host reads "Hacker", computer programming ability +1..."
"Ding! The host reads "Hacker", computer programming ability +1..."
"Ding! Trigger the intermediate photographic memory ability."
"Ding! The knowledge you have read is being stored..."
As Ye Xuan flips through the books, his computer programming ability continues to strengthen, and all the knowledge he sees is stored in his brain. Once the ability is triggered, computer knowledge will immediately appear in his mind.
This book "Hacker" is about network attacks. The knowledge involved is very extensive and advanced. If you don't have professional basic knowledge, you won't understand what it is talking about at all.
There are two most popular network attack methods at present, one is DDoS attack and the other is DoS attack.
DoS attacks generally use a one-to-one approach. When the target being attacked has low CPU speed, small memory or small network bandwidth, etc., its performance indicators are not high, and its effect is obvious.
With the development of computer and network technology, computer processing power has increased rapidly, memory has greatly increased, and gigabit-level networks have also emerged, which makes DOS attacks more difficult - the target's ability to "digest malicious attack packets"
"It has been strengthened a lot. For example, your attack software can send ,000 attack packets per second, but my host and network bandwidth can handle 10,000 attack packets per second, so the attack will not have any 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 very fast. His brain was working quickly, understanding and absorbing the knowledge he saw. At this time, he felt like he had discovered a new world.
Today is an era of rapid development of the Internet, so there are cyber attacks of varying degrees every day. Cyber warfare is a war without smoke.
The operation of satellites, navigation, aircraft, missiles, etc. all require the Internet. Once the network is destroyed or controlled by the enemy, the consequences can be imagined to be horrific. Therefore, every country attaches great importance to network security.
"Ding! Computer programming ability +1..."
"Ding! Photographic memory +1..."
Time passed little by little. When Ye Xuan finished reading this book, he was very shocked. Internet war was far more terrifying than he imagined.
"Ye Xuan, how are you? Have you gained anything?" Zhang Ming walked in at this time and asked when he saw Ye Xuan.
"Teacher Zhang, I didn't expect that this network war is quite terrifying. A single 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 on, let me show you some contents." After Zhang Ming finished speaking, he turned on his computer.
A video was played. It was a duel between hackers. Both sides used a large number of junk data packets to attack each other. Many financial companies, educational institutions, medical institutions, etc. were harmed to varying degrees, causing a lot of damage.
Loss.
The entire video only lasted a few minutes, but the content inside shocked Ye Xuan very much.
"Teacher Zhang, what should we do 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. Our country has two major organizations. One is the network security group 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 Hongke Alliance, a non-governmental organization. The people here are also very awesome. 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 Hongke Alliance is to protect China's network security, so our country's network has always been very safe under the protection of the two major organizations."
"Anyone who offends our country will be punished no matter how far away he is!" Ye Xuan murmured to himself, and hearing these words made his blood boil.
"Ye Xuan, if you want to know more, you can go to the Hongke Alliance Forum. It not only contains various histories, but also technical exchanges."
"I usually go up and take a look when I have free time to see if there are any news or technical exchange posts. If you are confident 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 Hongke Alliance." Zhang Ming chuckled.
"That's it. It seems I have to check out the Honker Alliance forum when I have time. By the way, Teacher Zhang, have you joined the Honker Alliance?" Ye Xuan asked.
"Uh, well..." Zhang Ming blushed and felt a little embarrassed.
Zhang Ming had already participated in several Hongke Alliance assessments, but failed them all. When he was suddenly asked by Ye Xuan, he felt a little embarrassed.
"Haha, to be honest, the teacher did not join the Hongke Alliance. It does not mean that the teacher is not strong enough, but that the teacher simply does not have the time."
"You see, in addition to teaching, the teacher also has to repair the computers of the school and some of his clients, so how can he have this time?"
"That's right. How can the teacher have time when he is so busy? If the teacher wants to join the Hongke Alliance, 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, don’t tell.
"Yes, yes, that's it. If the teacher has time, he will definitely take the assessment of the Hongke League. Joining the Hongke League will not be a problem." Zhang Ming said with a smile.
"Teacher Zhang, then I will read other books, and you should be busy first," Ye Xuan said.
"Okay, you can read whatever books the teacher has here. You can come over if you have time. In addition to reading, 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.
Zhang Ming was relieved when he saw Ye Xuan sitting on a chair reading a book. Fortunately, he reacted quickly enough, otherwise he would have been really embarrassed.
Ye Xuan found that the Internet was also very interesting. It was a virtual world, and you could do many things in this virtual world.
Moreover, the Internet is applied to all aspects of real life, so this network belongs to the second world. Every country attaches great importance to network construction and network security.
The more Ye Xuan watched, the more interested he became. He felt that some things that were impossible to achieve in reality could be achieved in the online world. (To be continued)
