On July 6th, the same drama was staged again.

Today was originally a roadshow for Suning Appliances to go public, but at two o'clock, Quanying.com's server suddenly stumbled and was completely paralyzed within two minutes.

After all, it is a subsidiary of the Shenzhen Stock Exchange. When you encounter trouble, it is still fine to find a few cybersecurity experts to come.

Although I made sufficient preparations in advance, the server still crashed.

In the computer room, Zhao Yifan saw sweat on his forehead, and the situation was exactly the same as yesterday. He knew very well that his knowledge was obviously not enough.

At least I fooled it yesterday, but today it seems that I can't get over this hurdle, so Zhao Yifan can only rely on these foreign players, "Mr. Liu, what's the situation?"

"The server's SYN_RECV queue has been filled with malicious packets and cannot accept new requests. This is a typical SYN, Flood attack."

“Is there a solution?”

Liu Gong nodded, but before Zhao Yifan could breathe a sigh of relief, he shook his head again, "There is a solution, but the distance cannot be dissolved in the near fire, so it will definitely not be able to recover today."

Zhao Yifan swears to the sky, he has never been as hatred and breathed as he does today. If he doesn't have an explanation today, he might have to get out tomorrow. Who is in the mood to think about other things?

Zhao Yifan ignored it, which did not mean that others were not interested. A security engineer who came with him asked: "Mr. Liu, as far as I know, there is currently no good defense method for SYN and Flood in the security field. What are your tricks?"

"I don't have any tricks, but I heard that there is a device that is very effective in defending against DDos attacks."

“What equipment?”

"Black hole."

...

Shortly after Quanying.com was paralyzed, Chen Qiaoshan and Liu Chang came to the headquarters of the Green League together.

The so-called headquarters is just a joke. The entrepreneurial situation has been hit by continuous setbacks, and Shen Jiye’s family has almost failed. After several relocations, the company is now nesting in a residential house in Liulangzhuang. The situation is really miserable.

"Is that right?" Liu Chang parked the car at the entrance of a small courtyard.

The large-scale demolition and construction of Zhongguancun was unstoppable. Not long ago, the renovation of the western area of ​​the city was successfully completed, and the eastern area was also put on the agenda. Even this urban village sandwiched between the Summer Palace and Haidian Park was demolished in many places.

Chen Qiaoshan was sitting in the co-pilot. This was the first time he had taken a newly bought Buick from the company. The air conditioning in the car was very high, which eliminated a lot of the heat.

Through the car window, he glanced out, "That's it, the door number matches."

Liu Chang was amazed, "This is a bit miserable. It is better to find two houses in Zhongguancun to demolish them than to be the conditions for this?"

"It's light to say that the monthly rent for the demolition house there can be lived here for one year. If it weren't for no way, who would have wanted to stay in this city village?" Chen Qiaoshan was used to it. The difficulty in starting a business is not as light as it said. Many big bosses have a glory in front of others, but the sadness of the past is not worthy of being told by others.

To be honest, Liulang Village is much better than Qianwang Village. Chen Qiaoshan was still a little uncomfortable when he suddenly came here from the city.

This place is located in the west of Beijing. Due to the construction of the Fourth Ring Road, a piece of the southeast corner of the village was occupied. The Wanliu Sports Park was originally planned, but a large piece was cut off. However, the park was not built, but a golf course was built in the name of greening.

Hearing the movement outside, Ye Xiaohu greeted him, "Mr. Chen, it's a hot day, please come and go for it yourself."

"Dr. Ye, that's all, I'll be out of here." Chen Qiaoshan admired Ye Xiaohu very much. He was rare to see such scientific researchers.

"Let me introduce it. This is Liu Chang, Kang Sheng's manager."

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

Liu Chang laughed and said, "Dr. Ye, I have long admired the name."

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

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

Ye Xiaohu suddenly realized that it was too hot and it was not convenient to say anything, so he quickly welcomed the two into the yard.

Chen Qiaoshan glanced casually and said that the farmyard was neatly tidy, but there was no sign of chaos.

After such a big disturbance, Chen Qiaoshan couldn't help but ask, "Mr. Shen and the others are not here?"

"Mr. Shen delayed something. He told me that he would definitely come before five o'clock." Ye Xiaohu was afraid that Chen Qiaoshan would be too worried, so he added: "Mr. Chen, I'm really embarrassed. I've really tripped up the matter. Don't worry, I'll call to urge me immediately."

"Don't worry, just wait and see." Chen Qiaoshan knew very well that this period of time would definitely be Quanying's business.

Ye Xiaohu didn't insist, so he brought two cups of tea, then moved a chair and sat opposite the two of them. "Mr. Chen, today is the day to sign the contract. There is a saying that I think I should say it in advance."

Today's farmyard is not as luxurious as installing air conditioners. Chen Qiaoshan lifted the lid onto the table and said, "If you work together in the future, you will have any problems, but it's okay to say it."

Ye Xiaohu was a little hesitant, "Mr. Chen, do you not know much about the current security market?"

Chen Qiaoshan nodded, there was nothing to hide.

"Then, I'll introduce you to the specific situation first." Ye Xiaohu took a palm-leaf fan, and there was an electric fan in the room. He had to tighten the two guests on the other side. He shouted and fanned a few times, feeling a little cooler, and then said: "Bandwidth determines the ability to resist cyber attacks. This is different from a virus, and you must have some understanding of this.

"Today's servers have very little exclusive bandwidth, most of which share 10M, but this can fully meet most bandwidth requirements."

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

How could Chen Qiaoshan not understand? The other party wanted to give up 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, what suggestions do you have for the company's next development?"

Ye Xiaohu was stunned. The investor in front of him seemed to be a disobedient person.

He couldn't help but worry that if such a person takes over Green Alliance, the company's prospects are worrying.

Ye Xiaohu could only sigh in secret. In a moment, he figured out how bad it would be. At least it was better than it is now. He has reminded him that people are willing to throw away money, so why bother to break it?

"Mr. Chen, please sit for a while. I'll go to the Bu family restaurant at the entrance of the alley to greet them and ask them to prepare some of the flavors of the village. Let's have a drink to celebrate in the evening." After a few words casually, Ye Xiaohu found an excuse to go out.

Chen Qiaoshan didn't stop him. He thought it very clearly. When the black hole was broken, everything would naturally come out. There was no need to explain it at this moment, and he couldn't explain it clearly.
Chapter completed!
