This Is Called Poor Students Class? This Is The Whole Class!

Chapter 282 Calm Attack And Panic Defense

Hackers are mysterious and scary in most people's cognition.

They hide behind the virtual network, stealing other people's information is like picking something out of a bag.

actually not.

Hackers are people too.

They just master the computer technology that most ordinary people can't touch or have not learned.

In fact, it is the same reason that everyone encounters a math problem in class and study.

Those who are difficult will not, and those who will meet will not be difficult, that is what it means.

In the well-equipped room, teachers and students Xu Jie and Liu Qingyun kept typing on the keyboard.

On the computer screen in front of them, a series of mysterious codes are running at high speed.

"Mr. Xu, the tens of millions of broilers we control are spread all over the world. Will we visit the official website of the puppet regime on Yizhou Island later, will they directly blow up their servers?"

While writing the code, Liu Qingyun could spare no effort to chat with Mr. Xu.

The so-called "broiler" is also called a puppet machine.

Refers to those terminal machines that can be remotely controlled by hackers.

Any networked device in the world may become a "broiler" in the hands of hackers.

And not limited to desktops, notebooks and other computer equipment.

Things like mobile phones, tablets, and even smart homes, etc., all have the possibility of becoming broilers.

Skilled hackers can freely manipulate these smart terminal devices and use them to do anything.

The network attack launched by Xu Jie and Liu Qingyun is one of the most common methods of network attack on the Internet:

ddos attack.

Also known as distributed denial of service attack.

The principle of this kind of network attack is not complicated. It is to use a large number of bots controlled by the hands to imitate the behavior of real users and initiate access requests to the target website or server.

In a short period of time, perhaps one second or even less, a large number of broilers initiate large-scale access requests, thereby quickly consuming the host resources of the target, making it impossible for the other party to provide services normally.

Take an inappropriate example.

It's like in a restaurant by the side of the road, a group of hooligans suddenly came.

This group of hooligans and hooligans have a large number of people. When they enter the restaurant, they only occupy a seat and do not order food. As a result, customers who normally come to the restaurant have no seats and cannot eat.

As a result, the restaurant cannot operate normally. They have to deal with the hooligans who are full of the store before they can continue to operate.

It takes a lot of time, energy and even money, but it is thankless.

This is the ddos ​​attack method commonly used by hackers.

While not quite exact, the meaning is more or less the same.

Everyone who surfs the Internet at ordinary times may have encountered a situation.

A certain website suddenly became popular, and the number of visits suddenly increased in a short period of time, which would cause the page to open slowly.

If the number of visitors in a short period of time exceeds the load of the server, the website page may not be opened at all.

This is what people often call the server blown up.

Ddos attack is similar to the principle.

In a short period of time, a large number of broilers are manipulated to initiate seemingly normal access requests to the server of the same website.

The purpose is to paralyze the other party's server.

This network attack method seems simple and brainless, but it is currently one of the most powerful and most difficult attack methods in the world.

It is a world-class problem, there is no fundamental solution, and we can only rely on other defense methods to mitigate the attack.

Even technology giants such as Google and Microsoft do not have a complete solution to ddos ​​attacks.

When Xu Jie heard Liu Qingyun's words, he kept his hands on his hands, smiled and shook his head.

"Although the puppet government of Yizhou Island is hateful, it may not be that simple to break through their official website just by relying on ddos ​​attacks."

"After all, even if they only use a small part of the people's fat and people's ointment they collect from the people every year for network security, it is not so easy for us to quickly break through their defenses."

"Although there is no way to completely solve the ddos ​​attack, it is still no problem to use related technical means to mitigate the attack or increase the threshold of the attack."

While the teacher and the student were launching a cyber attack, Xu Jie was also teaching Liu Qingyun.

Moving teaching into actual combat is most suitable for cultivating computer technical talents like Liu Qingyun who need very strong hands-on ability.

No matter how solid the computer theory is, if no effective code can be typed out, it will only be a theory on paper in the end.

Besides, Xu Jie's expectation for Liu Qingyun is not as simple as participating in a small informatics competition.

Computer technology originated in the West.

No matter how smart the people of Longguo are, most of the underlying protocols of computers still have to use the Western ones.

Why are all widely used programming languages ​​in English?

Because you create and develop a programming language in another language, and penetrate to the bottom layer, you still have to use other people's inventions and technologies.

The foundation is always someone else's, even the house is someone else's.

You only have the right to live or decorate.

Want to change the lowest protocol?

There are no doors!

When Xu Jie was training Liu Qingyun, the most common sentence he told him was:

Learn from barbarians to control barbarians.

It is an unchangeable fact that modern science originated in the West.

Then Xu Jie thought, is there a way to let Longguo's computer technology achieve cornering overtaking without breaking the underlying protocol?

Xu Jie didn't know, and neither did Liu Qingyun.

But they are all willing to work hard for this great vision.

Liu Qingyun nodded with a smile when he heard Teacher Xu's words.

"Teacher Xu, I know everything."

"You have already taught me about the defense methods of ddos."

"Whether it is using high-performance network equipment or deploying CDN, the essence is to divert and divert the attack."

"The more than 10 million chickens we have in our hands seem to be a lot, but after heavy defenses, it is hard to say how many of them will finally break through the blockade."

"I don't know how skilled the operation and maintenance personnel of the puppet regime in Yizhou Island are? Is it enough for us to fight?"

While the two were talking, more than 10 million broilers located in more than 100 countries and regions around the world have already started accessing and attacking the official website of the puppet regime on Yizhou Island under their control.

Yizhou Island, Yibei City, Network Security Office of the Puppet Regime.

"Beep beep!"

A sharp siren suddenly rang through the building.

"North! What's going on?"

"Did you make it?"

"I don't make it."

"Oh, it's annoying, someone is attacking our server again."

"Hurry up and deal with it. Let me tell you, if you don't deal with it, you will be scolded by the director."

...

A strong "motorcycle smell" wafted from the network security department.
