On July 6, the same drama played out again.

Today was originally a roadshow for the listing of Suning Electric, but as soon as it arrived at two o'clock, the server of the whole film network suddenly froze, and the whole line was paralyzed within two minutes.

After all, it is a subsidiary of the Shenzhen Stock Exchange, and if you encounter trouble, it is no problem to find a few network security experts to come over.

Despite all the preparations, the server crashed.

In the computer room, Zhao Yifan saw sweat on his forehead, the situation was the same as yesterday, he couldn't be clearer in his heart, his own little Taoism was obviously not enough.

Yesterday was a fool, but today it seems that this hurdle cannot be passed, and Zhao Yifan can only hope for these foreign aids, "Liu Gong, how is the situation?"

"The server's SYN_RECV queue is already full of malicious packets and cannot accept new requests, which is a typical SYN and Flood attack. ”

"Is there a solution?"

Liu Gong nodded, but before Zhao Yifan could breathe a sigh of relief, he shook his head again and again, "There is a way, but far water can't dissolve the near fire, and it will definitely not be able to recover today." ”

Zhao Yifan swore to the sky, he had never hated talking and panting as much as he did today, if he didn't explain today, maybe he would have to get out of the house tomorrow, who would be in the mood to think about other things.

Zhao Yifan ignored it, it didn't mean that others weren't interested, and a security engineer who came over with him asked: "Liu Gong, as far as I know, there is no good defense method for SYN and Flood in the security field at present, what are your tricks?"

"I don't have any tricks, but I've heard that there's a device that's very effective at defending against DDos attacks. ”

"What equipment?"

"Black holes. ”

……

Shortly after the whole film network was paralyzed, Chen Qiaoshan and Liu Chang went to NSFOCUS's headquarters together.

The so-called headquarters is a joke, the business has suffered successive setbacks, Shen Jiye's family foundation is almost lost, the company has been relocated several times, and now it is nested in a house in Liulangzhuang, and the situation is really miserable.

"Is this it?" Liu Chang parked his car at the gate of a small courtyard.

Not long ago, the transformation of the western district of the city was successfully completed, and the eastern district was also put on the agenda.

Chen Qiaoshan sat in the co-pilot, this was the first time he sat in the company's newly bought Buick, the air conditioning in the car was turned on sufficiently, but a lot of summer heat was eliminated.

Through the window, he glanced out twice, "That's it, the house number matches." ”

Liu Chang was surprised, "This is also a bit miserable, looking for two temporary demolition houses in Zhongguancun are better than this, right?"

"It's easy to say, the monthly rent of the demolished house over there can live here for a year, if there is no way, who wants to nest in this urban village. Chen Qiaoshan is accustomed to it, the difficulty of starting a business is not as light as it is said, many big bosses are in front of the scenery, but the sadness of the past is not enough for outsiders.

To tell the truth, Liulangzhuang is much stronger than Qianwang Village, and when he came here from the urban area suddenly, Chen Qiaoshan was still a little uncomfortable.

This side is located in the west of Beijing, because of the construction of the fourth ring road, the southeast corner of the village was occupied, the original planning of Wanliu Sports Park, and was crossed out of a large piece, but the park was not built, but in the name of greening to build a golf course.

Hearing the movement outside, Ye Xiaohu greeted him, "Mr. Chen, it's a hot day, and I'm bothering you to go for it yourself." ”

"Dr. Ye, that's the way to say that. Chen Qiaoshan admires Ye Xiaohu very much, and it is rare for such scientific researchers to be able to put down the shelf and go out to sell.

"Let me introduce you, this is Liu Chang, Kangsheng's manager. ”

Ye Xiaohu hurriedly greeted: "Hello, Mr. Liu, I am Ye Xiaohu, and I am currently the product manager of NSFOCUS. ”

Liu Chang smiled and said, "Dr. Ye, I have admired my name for a long time. ”

Ye Xiaohu looked surprised, "What, Mr. Liu knows about me?"

Chen Qiaoshan helped explain: "She is a family with Lao Wang of the Qingshan Forum. ”

Ye Xiaohu suddenly said that it was a hot day, and it was inconvenient to say anything, so he hurriedly welcomed the two into the courtyard.

Chen Qiaoshan glanced at it casually, and the small courtyard of the farmhouse was neatly tied, but he couldn't see the slightest mess.

With such a big movement and no one else in sight, Chen Qiaoshan couldn't help asking, "Mr. Shen, aren't they there?"

"Mr. Shen was a little delayed, and he explained that he would definitely come before five o'clock. Ye Xiaohu was afraid that Chen Qiaoshan would be too careful, and added: "Mr. Chen, I'm really embarrassed, I really stumbled things, don't worry, I'll call to urge you immediately." ”

"Don't be in a hurry, just wait slowly. Chen Qiaoshan knew very well in his heart that what could keep Shen Jiye busy during this time period must be Quanying's business.

Ye Xiaohu didn't insist, he brought two cups of tea first, and then moved a chair to sit opposite the two, "Mr. Chen, today is the day of signing the contract, there is a sentence, I think it should be said in advance." ”

Today's small farm yard is not yet luxurious enough to install air conditioning, Chen Qiaoshan lifted the lid of the cup and put it on the table, and then said: "Everyone will work together in the future, if there is any problem, it doesn't hurt to say it." ”

Ye Xiaohu was a little hesitant, "Mr. Chen, you don't know much about the current security market, right?"

Chen Qiaoshan nodded, there was nothing to hide.

"In that case, let me give you a brief introduction. Ye Xiaohu took a pu fan, there was an electric fan in the room, and he had to close to the two guests opposite, he called the fan a few times in a row, feeling a little cooler, and then said: "Bandwidth determines the ability to resist network attacks, which is different from viruses, and you must know this."

"Today's servers have very little dedicated bandwidth, most of them are shared 10M, but this can fully meet most of the bandwidth requirements. ”

After Ye Xiaohu finished speaking, he glanced at the two people opposite.

Chen Qiaoshan couldn't understand that the other party wanted to dispel his idea of betting, but the result was destined to disappoint the other party.

There was no good way to convince Ye Xiaohu, so Chen Qiaoshan had to change the topic and said, "Dr. Ye, do you have any suggestions for the company's next development?"

Ye Xiaohu was stunned, the investor in front of him seemed to be unpersuaded.

He couldn't help but be a little worried, such a person became the owner of NSFOCUS, and the company's prospects were worrisome.

Ye Xiaohu could only sigh secretly, and in a blink of an eye he figured out how bad it could be, at least it was better than now, and he had been reminded that people were willing to throw money, so why bother to break it.

"Mr. Chen, you sit down for a while, I'll go to the Bujia restaurant at the entrance of the alley to say hello, let them prepare some village flavors, and let's have a drink to celebrate in the evening." After a few casual words, Ye Xiaohu found an excuse to go out.

Chen Qiaoshan didn't stop it, he thought about it very clearly, when the black hole was broken, everything would naturally fall out, there was really no need to explain it, and he couldn't explain it clearly.
