That night, Nanming held a celebration party, everyone gathered together, ate and drank, and was happy for half the night.

During the banquet, Nanming discussed with everyone about investing in the lazy god special industry, and everyone had no opinions, and discussed the next investment with everyone for a long time, and then waved happily to let everyone go back to rest.

Who would have thought that before he went back, Su Hongyi received a phone call, was stunned when he heard the words, and said, "What are you talking about?" ”

Su Hongyi walked to Nanming's side, lowered his voice, and said, "The Supercomputing Research Institute called, saying that the load of Qingda Lazy God is abnormal, and the network is particularly congested, and it is suspected that it has been attacked." ”

"Attack, what type of attack?" Nan Ming was stunned for a moment, and when he heard the network congestion, the letters DDoS immediately flashed in Nan Ming's mind.

"The person on duty said it was most likely a DDoS attack. Su Hongyi said.

Nan Ming Heart Dao, sure enough.

This afternoon, Nanming also thought about whether someone would attack Lazy God Technology, and it really came tonight.

"Attack?" Yang Ji was startled when he heard these two words, and his hand touched his belt: "Who?

"It's not that kind of attack, it's a cyber attack. Nanming explained.

The so-called DDoS attack is DistributedDenialofService, that is, a distributed denial-of-service attack. To put it simply, it is to control a large number of computers, constantly make requests to one server, keep connecting, and fill the entire broadband with packets that come and go, making it inaccessible to people who want to access the site.

It's a simple and brutal attack, and there's almost no good way to defend against it, and the only way to do it is to increase the bandwidth.

"Cyber Attack...... DDOS?" Zhao Gaofeng and Yang Ji muttered a few words of this, their faces dazed. The feeling of being powerful and nowhere to go, "Is it just a hacker?"

"Guys with DDOS, where is some kind of hacker. Although he doesn't know much about hacking skills and network security, he is also a master of programming after all, and there is still a bypass.

"You can't be careless. If you use DDOS to cover up other attacks, it is also difficult to prevent them. Su Hongyi said.

"Let's go over and have a look!" Nan Ming dragged Su Hongyi and Han Dongdao, "Everyone else is okay, go back and rest, you have all worked hard today." ”

"How can you leave at such a time?" Everyone was excited, and they all said that they wanted to go over and have a look, even the old man Jiang and Jiang Chaohua, who were in charge of cooking, rolled up their sleeves, and there was a feeling that they were going to fight in a group, which made Nan Ming cry and laugh.

Zhao Gaofeng and Yang Ji were pinching their belts, and they didn't feel good in their hearts. Both of them are engaged in security, and they always feel that no matter what type of attack, they should follow.

Today, during the day, he just made a bold statement, saying that he would protect Nanming well and ensure that no one would want to hurt Nanming, and he was attacked at this time, how can this work?

When the group arrived at the computer room, the operation room was immediately crowded. In the computer room, the teacher on duty and several graduate students were already there. Seeing Nan Ming, he hurriedly said: "Mr. Nan, we confirm that we have been attacked by DDoS, do you want to go offline temporarily?"

The so-called offline is to temporarily disconnect the server from the network, since there is no attack target, then the other party's attack will naturally not be completed.

Qingda Lazy God doesn't have any important business that needs to be online right now.

"The other party is attacking the Qingda Lazy God. Or is it the page of Lazy God Technology?" Nan Ming asked, some time ago, Lazy God Technology moved the page to Qingda Lazy God, and this matter was still done by Su Hongyi.

"Judging from the log files, the attackers targeted Lazy God Technology. The teacher said.

"Sure enough......" Nan Ming frowned, lazy god technology is a big move.

Su Hongyi said: "Actually, it is also a way to temporarily take the Qingda Lazy God offline. Our Lazy God Technology page was originally placed on the rented server, if we go offline, all the attacks point to the original server, when we rented the server, the service provider provided the business of preventing DDoS, and it was their turn to worry. ”

When they bought the service, they bought a similar security service, and in this case, it was time to enjoy the service.

"Then how can it be done!" Although he didn't know what was going on, Peng Lao was unhappy, "How can you back down when you are beaten? Isn't that no egg? No, you have to fight back!"

"I think so, too. Nan Ming rubbed his nose, full of unhappiness, what a happy day it was today, but someone came to make trouble, "If we want to fight back, is there any good way?"

"DDoS is the simplest and most brutal way, and the response can only be simple and brutal, they take up our broadband, and we can only increase it. A teacher said.

DDos is like a rush to buy, a large group of customers are blocking the door, people can't get in or out, if you want to open normally, you have to open more doors, you can't use machine guns to surprise these customers.

That's the most annoying thing about DDoS.

"Then increase the bandwidth. "Nan Ming Dao.

The teacher went to contact the service provider, although it was already evening, but as a big customer, the service provider quickly responded, and allocated a batch of idle broadband to Qingda Lazy God.

Qingyang University also connected some other broadband to Qingda Lazy, and soon the bandwidth of Qingda Lazy God exceeded 10G.

In fact, for ordinary companies like Lazy God Technology, which do not provide too many network services, the server only needs 10M, and at most 100M bandwidth is enough. And the bandwidth of 10G is already 100 times that of 100M, and you can download a 1.2G movie in one second.

10G, generally speaking, is already the upper limit of the general type of DDoS attack power, if it is just a grudge competitor, boring hackers scattered on the network, or other people who look at lazy technology unpleasantly, 10G broadband, is enough to accommodate their DDoS attacks.

The computer controlled by network hackers is called broilers, and most of the servers are controlled, and if a broiler is usually 10M wide, it will cause a 10G attack, at least 1000 broilers, which is already a very large number.

However, the increased bandwidth is once again instantly crammed.

"Plus!" Nan Ming frowned.

After a while, the mobilized bandwidth continued to increase, and the bandwidth increased to 100G!

But it didn't work, and the bandwidth was filled up again in an instant.

"Plus!" Nanming's brow furrowed closer.

The teacher went to make a phone call, but after a while, he came back with a gloomy face and said, "The service provider said that it can't be added anymore, and now is the peak time for Internet access, and if they crowd out other broadband, they will be complained." The service provider advised us to seek help from a security company. ”

Qingyang is a non-node city, and the total bandwidth it has is only more than 700G, and the service provider has allocated one-seventh of the bandwidth to Lazy God Technology, which has been benevolent and righteous.

"I'm a fork!" Nan Ming was so angry that he burst into a foul language, not aimed at the service provider, the service provider just helped them add broadband, which was already very powerful, and he was angry that this was definitely an organized attack.

Attacks above 100G are already very rare.

And now it seems that this number is not the upper limit at all.

"I won't believe it, get them out!" Nan Ming snorted.

"Pull it out......" Everyone looked at each other, this is a bit difficult.

At this moment, Yang Ji's phone rang, he answered the phone, and said to Nanming: "It was Qing Zhongtang's assistant Wang Xing who called, and he said that he had someone who could help." ”

Yang Ji didn't want Nanming to contact Wang Xing too much, but he couldn't take care of it at this time.

Not long after, Wang Xing arrived, and at the same time brought a black girl with pigtails.

Hacker TD.

Seeing that it was TD, everyone was surprised, they thought that TD had been arrested or repatriated, who would have thought that TD was still in China.

When TD came in, she was still a little excited, although Wang Xing didn't say it explicitly, but she also knew that this was the location of the magical "Vision of God", and when she heard that this server was attacked, TD immediately volunteered to come, and her heart was more angry than Nan Ming, like an old hen guarding her cubs.

Joke, this is the old lady's "GOD'sEYE"!

It was not the first time TD had come into contact with Qingda Lazy God, and she quickly entered the state, she carefully analyzed the logs, and said to Nanming: "DDoS attacks are just a front, someone is trying to invade. ”

"Can you catch him?" asked Nanming.

"The other party is very cunning and sophisticated, the intrusion is sent by the attacking server, and there are nearly 10,000 messages in an instant, which is difficult to track ......"

Nan Ming's brows furrowed, and TD hesitated: "I can try, but the odds are too low, unless you can analyze tens of thousands of attacks in an instant and compare the subtle differences among them, it is possible to find the source." (To be continued......)
