Chapter 1877 There is something in the words

In some novels, hackers are described as omnipotent, but this is not actually true to the actual situation.

Theoretically, hackers are thousands of miles away. To enter the system, there must be a network link.

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

In fact, the addresses that can be accessed from the outside are not the core part. Even if they are accidentally captured by hackers, it will not cause any harm. Just restore and refresh and you will be done.

As for systems that can be accessed from the outside, such as mobile banking, which has not yet been launched, the above services actually have a complex and sound error correction mechanism. First, the content you input can only be performed on the page assigned to you by the bank. There is a strict certificate exchange in the middle, and then the information will be encrypted and sent to the bank's receiving server for decryption. It will go through several firewall verifications and ciphertext verification to prove that it has not been tampered with, and then it will pass through both internal and external Network translation mapping into the intranet.

The information entering the intranet will meet the simplified requirements. The information carried cannot be execution code. When entering the system, it can only be used as data and not as a program. There may be many processes in between. Transcoding in one step also ensures the “cleanness” of the data.

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

This is like attacking a city in ancient times. The port you attack is like breaking the city gate. After entering, there will be an urn city waiting for you. The urn city is full of densely armed people waiting, requiring everyone to come in. Only people who have to take off their clothes to enter a big city will not give you a chance to be a hacker.

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

In theory, this can be regarded as the "back door" of the system. In order to facilitate the entry into the big city, some people disliked the trouble of entering the Wengcheng first and stripping off their clothes to go through the security check. They quietly opened a dog hole in some corner of the city and sneaked in every time. Go into the city.

For the convenience of work, Zhou Zhi established a dedicated data line between the headquarters of the Clover Computing Center and Sui Huaxuan.

This data line originally realized data transmission through dial-up. The establishment of the line was even earlier than the establishment of Clover Group. With the expansion of the group's business and the opening of the satellite network, this line has become more and more sophisticated. In fact, it is not used anymore.

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

However, Sui Huaxuan's dedicated line network is only connected to Zhou Zhi's large study room. It is also where Feng Xueshan currently serves as her office in Sui Huaxuan that it is connected to the Clover Group's intranet.

Suihuaxuan also has a large conference room, which is the "business center" that is basically equipped in today's high-end hotels. However, the network line in that center is connected to the external network and is physically separated from the dedicated line in the large study room.

In other words, if Black Cat wants to log into the intranet of the Clover Group in Suihuaxuan, he needs to go to the big study room to operate it. There are many valuable things in his big study room. Feng Xueshan personally With the key in hand, it is impossible to let others in.

But these are not important anymore, someone will answer all this soon.

"First... Sir, do you want to get off here?"

After hanging up the phone, Zhou Zhi fell into deep thought. Even the taxi driver suddenly realized when he drove the car to the end of Huanhua River Bridge. Not aware yet.

The driver was quite patient. He had a very happy chat with the young man in the back seat and treated him as a college student who was full of curiosity about society. When Zhou Zhi later mentioned the stock market, the driver just thought he was inexperienced. I don’t know what I heard from that elder relative.

Until Zhou Zhi took out his mobile phone to answer the call, this mobile phone was very similar to the latest Ericsson, which made the driver feel that the guy in the back seat was not simple.

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

After Zhou Zhi made a phone call and there was no response for a long time, the driver didn’t dare to speak. In the end, it really delayed his own business, so he had to interrupt Zhou Zhi’s meditation.

"Ah, sorry, it's right here." Only then did Zhou Zhi react and quickly apologized. "The fare is thirty-five."

"I'm really sorry for delaying you for so long, so there's no need to look for it." Zhou Zhi gave him a fifty.

The driver rubbed it secretly and felt the texture of the real money: "Thank you. By the way, I will give you a business card. If you want to take a taxi to the airport or something in the future, you can call me."< br>
Zhou Zhi found it a bit funny, these days even taxi drivers have business cards printed on them.

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

"Where are you now?" Feng Xueshan over there became angry when she heard this: "What do you want to say?!"

When Zhou Zhi heard this, he knew that Feng Xueshan had misunderstood. She mistakenly thought that she was talking to Yang He Nai Wai, deliberately making fun of you.

In this case, we have to make fun of it. Zhou Zhi immediately became angry: "Don't be so sensitive. It's like you are doing something bad..."

"You bastard ! I’m not working for you yet! Transform the front desk and personnel system. I’m almost exhausted from adjusting the plan. If I had known this, I might as well have read the water meter in Manzhou!”

“You haven’t even read the water meter in Manzhou for a few days, okay? "Zhou Zhi smiled and said: "Aren't you outside in front of the flowers and under the moon?"

"You seem to be in a good mood today?" Zhou Zhi didn't need to see him in person. Zhou Zhi could feel Feng Xueshan rolling her eyes on the phone: "Thank you for your concern. I deserve retribution for finding someone who won't waste time." How about being a boyfriend?”

"Hahaha, Xueshan, you don't understand. The greatest romance for a man is to obey what he says. Which girl didn't decorate her own rag doll when she was a child? She still has such an opportunity in her twenties, so cherish it. "

" Cluck..." Feng Xueshan finally laughed. After laughing, she added: "There are some things that only I can say. If you dare to say these things to him, then I will be angry!"

"I am again! You're not a fool, I need you to explain specifically, eh, I found you I'm a little too biased now..."

"Then quickly find someone who favors you." Feng Xueshan smiled arrogantly: "I will give her a chance to make me jealous, so that we can be even. , Hahahaha..."

"Stop making trouble, are you still working overtime? In IT Plaza or Suihuaxuan?"

"In Suihuaxuan, you are oppressed to death, I have to enjoy myself in Suihuaxuan to make up for it! Huh? What's really going on with you?"

"That's good. Please check quietly. Is there a guest named Mai Xiaomiao in our Suihuaxuan? She is probably a young girl. ...eighteen, nineteen, twenty-one "Two?"

"What's wrong?" Feng Xueshan's voice suddenly lowered: "No need to check, this girl is here with us. Usually the people who come to our place are old men, even if there are beauties, they are always with us. I came here with the old man. This girl is young and dressed simply, unlike those other women. I am very impressed.”

“I am at Suihuaxuan Bridge now, where does she live?” Room?”

"What?! You're here..." Feng Xueshan was startled, and then quickly lowered her voice: "Are you really back?"

Then the words suddenly had something else: "What are you doing for That girl is back?”
