Riding the wind of rebirth

Chapter 1877: There is something behind the words
In some novels, hackers are described as omnipotent, which is not true in reality.

Theoretically, if a hacker wants to enter the system even if he is thousands of miles away, there must be a network link.

Many systems, such as banks, military, and government agencies, actually strictly control the physical connection between internal and external networks, and many systems are physically disconnected directly.

The addresses that can be accessed from the outside are actually not the most core parts. Even if they are accidentally occupied by hackers, it is harmless and can be solved by simply restoring and refreshing.

As for the core systems that can be accessed from the outside, such as mobile banking that has not yet been released, the services above actually have a complex and sound error correction mechanism. First of all, the content you input can only be done on the page given to you by the bank. There is strict certificate interaction in the middle. Afterwards, this information will be encrypted and sent to the bank's receiving server for decryption. It will go through several firewall checks in the middle, and it will also go through ciphertext verification to prove that it has not been tampered with. Only then will it enter the intranet through internal and external network translation and mapping.

The information entering the intranet will meet the most simplified requirements. The information carried cannot be executable code. It can only be used as data and not as a program after entering the system. It may need to undergo multiple transcoding in the middle to ensure the "cleanliness" of the data.

Therefore, it is impossible for hackers to break into the system through these external channels.

This is just like attacking a city in ancient times. The port you break into is like breaking the city gate. After you enter, there will be a city wall waiting for you. The city wall is full of densely armed people waiting, and all those who come in are required to take off all their clothes before entering the city. There is no chance for you to be a hacker at all.

But there is an exception, which is what Zhou Zhi is now told by Hu Tianyu.

Theoretically, this can be regarded as the "back door" of the system. Some people, in order to facilitate entry into the big city, dislike the trouble of taking off clothes and going through security checks before entering the city, so they secretly opened a dog hole in some corners of the city and sneaked into the city from here every time.

In order to make work more convenient, Zhou Zhi installed a dedicated data line between the Clover Computing Center headquarters and Suihuaxuan.

This dedicated data line originally achieved data transmission via dial-up. The line was established even earlier than the founding of the Clover Group. With the expansion of the group's business and the opening of the satellite network, this line was no longer used in Zhouzhi.

Now this line is mostly used by Feng Xueshan when she is taking care of both sides of the business.

However, Suihuaxuan's dedicated network is only connected to Zhou Zhi's large study, which is also where Feng Xueshan currently uses her office in Suihuaxuan, and it will then be connected to the Clover Group's intranet.

Suihuaxuan also has a large conference room, which is the "business center" that most high-end hotels are equipped with nowadays. However, the network line of that center is connected to the external network and is physically isolated from the dedicated line of the large study.

In other words, if Black Cat wants to log into the Clover Group's intranet at Suihuaxuan, he needs to go to the big study to do so. However, there are many valuable things in his big study, and Feng Xueshan holds the key herself, so it is impossible for her to let others in.

But none of this matters anymore, someone will answer all of this soon.

"Sir, is this where we get off?"

After hanging up the phone, Zhou Zhi fell into deep thought and didn't even notice that the taxi driver had driven the car to the Huanhua Creek Bridge.

The driver was quite patient. He had been chatting happily with the young man in the back seat and treated him as a college student who was full of curiosity about society. Later, when Zhou Zhi mentioned the stock market, the driver treated him as a young man who was inexperienced and didn't know what he had heard from the elder relative.

It was not until Zhou Zhi took out his cell phone to answer the call, this phone was very similar to the latest Ericsson model, that the driver felt that the guy in the back seat was no ordinary person.

When the driver heard Zhou Zhi talking about black cats, systems, networks, ports, and even mentioned foreigners, he couldn't help but feel a little creepy.

After Zhou Zhi finished his call and there was no response for a long time, the driver didn't dare to speak. Finally, he felt that it was delaying his business, so he had to interrupt Zhou Zhi's thoughts.

"Oh, sorry, it's right here." Zhou Zhi finally realized what was happening and quickly apologized. "The fare is thirty-five."

"I'm really sorry for taking up so much of your time. No need to give me the change." Zhou Zhi handed over a fifty-dollar bill.

The driver rubbed it secretly and felt the texture of the real money: "Thank you. By the way, I'll give you a business card. If you need to take a taxi to the airport or something in the future, you can call me."

Zhou Zhi found it a little funny that even taxi drivers had business cards printed on them these days.

After the driver left, Zhou Zhi picked up his phone again and called Feng Xueshan: "Xueshan, where are you now?"

"What do you mean where are you now?" Feng Xueshan got angry when she heard it: "What do you want to say?!"

As soon as Zhou Zhi heard it, he knew Feng Xueshan had misunderstood. She mistakenly thought that he had concluded that she was having an affair with Yang He and was deliberately teasing her.

In this case, he had to tease her a little. Zhou Zhi immediately became sarcastic: "Don't be so sensitive. It's like you're doing something bad..."

"You bastard! I'm still working for you! I'm almost dying of exhaustion from restructuring the front desk and adjusting the personnel system. If I'd known this would happen, I might as well have just been reading water meters in Manzhou!"

"You haven't been reading water meters in Manzhou for a few days, have you? In the blink of an eye, you are sitting in an office." Zhou Zhi smiled and said, "You haven't been outside enjoying the flowers and the moonlight?"

"You seem to be in a good mood today?" Zhou Zhi didn't need to see it in person, he could feel Feng Xueshan rolling her eyes on the other end of the phone: "Thank you for your concern, I deserve it for finding a boyfriend who doesn't know how to spend time together. What's wrong?"

"Hahaha, Xueshan, you don't understand. The greatest romance for a man is to obey his orders. Which girl didn't decorate her own doll when she was a child? You still have such an opportunity when you are in your twenties. You should cherish it."

“Hahahaha…” Feng Xueshan was finally amused and continued, “There are some things that only I can say. If you dare to say these things to him, I will be angry!”

"I'm not a fool. I don't need you to explain it to me. I find that you are a little too biased now..."

"Then quickly find someone who is biased towards you." Feng Xueshan laughed arrogantly: "I'll give her a chance to make me jealous, so that we're even, hahahaha..."

"Stop it, are you still working overtime? At IT Plaza or Suihuaxuan?"

"I oppressed you to death in Suihuaxuan. I have to make up for it by enjoying myself in Suihuaxuan! Hmm? Is there really something wrong?"

"That's perfect. There's something you can check quietly. Does Suihuaxuan have a guest named Mai Xiaomiao? Is she a young girl, probably... 18 or 21?"

"What's wrong?" Feng Xueshan lowered her voice suddenly: "No need to check, the girl is here with us. Usually the people who come here are old men. Even if there are beauties, they are always accompanied by old men. This girl is not very old and she is dressed simply, unlike those women. I have a deep impression of her."

"I'm at the bridgehead of Suihuaxuan now. Which room does she live in?"

"What?! You came..." Feng Xueshan was shocked. She raised her voice and then lowered it quickly: "You really came back?"

Then there was suddenly something else in his words: "You came back for that girl?"
