Liu Xiao wanted to find that Wang Gong, but when he rushed to the department where he was building today, he found that the building had already been empty and the door was closed. Liu Xiao knocked on the door, but no one opened the door, but the internal guard who was in charge of the guard work was summoned.

It seems that Wang Gong and they have indeed left, Liu Xiao is a little depressed, what should I do now, I don't know the contact information of Wang Gong. After thinking about it, Liu Xiao felt that he could only go to Liu Chen or Boss Xiong, one of them participated in the exercise, and the other knew the person in charge of the exercise, so he should be able to convey his meaning.

Liu Xiao finally decided to go to Boss Xiong, he didn't want to go to Liu Chen, first, he felt that Liu Chen couldn't manage this mess, and second, he didn't want to get too close to the people in the network supervisor. After making up his mind, Liu Xiao went straight to Boss Xiong's house.

"Liu Xiao, it's you!" Boss Xiong opened the door and saw Liu Xiao, he was very happy, winked at Liu Xiao, and said in a low voice: "My child happens to be at home, you help me persuade him!"

Liu Xiao was a little embarrassed, "Mr. Xiong, this is slow in advance, I have more important things to discuss with you!"

Boss Xiong was a little surprised, his expression was stunned, and then he said: "That's okay, go to my study and talk about it!"

"Come to me so late, there must be something urgent, right?" Boss Xiong poured Liu Xiao a glass of water.

"It's about this cyber exercise in Haicheng. Liu Xiao took a breath, "I've been installing equipment for various departments in the past few days, and then I found some of these problems, and I don't know who to talk to, so I came to you." ”

Boss Xiong let out an "oh", "You say!"

Liu Xiao cleared his throat, "Then let me pick the most important thing, the network that Haicheng has renovated this time has a flaw in the emergency response mechanism, if this flaw is mastered by hackers, hackers will take the opportunity to create a series of false emergencies, and Haicheng will fall into a state of chaos at that time." ”

"This ......" Boss Xiong really doesn't understand hackers, "I don't understand what you tell me." Well, I'll ask you a question, are you really talking about any of these things?"

"Indeed!" Liu Xiao nodded, "I can guarantee that the problem does exist, and I am definitely not alarmist." ”

Boss Xiong groaned for a while, and said, "Since you said so and found me here, then I naturally have to take care of it." In this way, tomorrow you go with me to the city government, and I will take you to meet the person in charge of this project, and you will reflect this problem. ”

"Okay!" Liu Xiao responded, "It's so late, then I won't bother much, I'll wait for you at the gate of the city hall tomorrow morning." ”

"Don't worry, don't worry!" Boss Xiong stopped Liu Xiao, "You have said something, but I haven't said anything yet, hehe, my kid ......"

"Oh......" Liu Xiao knew what Boss Xiong meant, in Boss Xiong's heart, his own children's affairs must be more important than the Haicheng exercise. After thinking for a while, Liu Xiao said: "That's it, when the child rests on Sunday, you take him to the City Planetarium, and I'll talk to him there." ”

"Planetarium?" Boss Xiong didn't understand what Liu Xiao meant.

"That's right, it's the planetarium, you'll understand when the time comes!" Liu Xiao didn't explain much, and said goodbye to Boss Xiong at the moment.

The next day, Liu Xiao waited at the gate of the city government early, and Boss Xiong arrived a little later than him by about ten minutes.

Boss Xiong got out of the car, "Liu Xiao, wait a minute, let's go, follow me in." The doorman of the city government knew Boss Xiong and let the two of them in without hindrance.

When the two came to the twelfth floor of the municipal government building, they saw a sign hanging at the door of the office, "Haicheng Network Transformation Project Leading Group". Boss Xiong didn't knock on the door, he pushed the door directly in, and there were several people inside, each sitting in front of his office. There was a middle-aged man in his forties at the innermost, most of his hair had been bald, and there were a few left, which were softly covered on the top of his head.

"Lao Tu, what are you busy with early in the morning?" asked Boss Xiong and walked to the innermost.

The bald middle-aged man raised his face with a look of surprise, "Boss Xiong, what kind of wind is blowing you here, come, sit down." ”

"Don't sit down!" Boss Xiong waved his hand, "Come, let me introduce you, this is Liu Xiao, a computer genius, he has something to say to you." ”

"Hehe!" Lao Tu smiled and said, "Sit, sit, sit down." ”

Liu Xiao saw that there were people coming and going in the office, and he said, "Is there a quiet place here?"

Lao Tu didn't say anything, stood up, "Let's go, there's no one in the conference room next door, let's talk over there." After speaking, he smiled and led the way in front.

"Say, what's the matter with me?" Lao Tu asked after seeing that the two of them were seated.

"That's right!" Liu Xiao sorted out his thoughts, "This Haicheng's network transformation plan is flawed and easy to be exploited by hackers. ”

"Defects?" Lao Tu's eyes widened, "What defects? How do you know there are defects?" ”

"On top of the network of all the departments of the city government, there is a decision response center, and the processing system of this center has an emergency response mechanism, which is automatically activated when a major emergency is detected. Liu Xiao looked at Lao Tu, "Right?"

Lao Tu nodded, "That's the case, you go on." ”

"If a hacker hacks a department of the city to deceive the response center and make the response center think that a major emergency has occurred, if the response center is unguarded, or if there is no response within 10 seconds, the emergency response mechanism will be activated, and the system will make various decisions based on the hacker's fake event to ensure that the city is not affected by the incident. Liu Xiao paused, "Think about it, this event didn't exist in the first place, if the response system issued a decision, wouldn't the city fall into a state of self-chaos at that time?"

Lao Tu's face did not change, he sat up straight, and he didn't know if he understood, but he coughed twice and asked, "Then what do you mean?"

"Revising the plan for the emergency response mechanism!" Liu Xiao replied.

"Revised?" Lao Tu frowned slightly, "How much time will it take to revise this?"

"Not sure! If it goes well, you can modify the test in half a month!" Liu Xiao roughly estimated the time, under the premise that the network structure remains unchanged, only modify the response mechanism, from modification to testing, it will probably take so long.

"Half a month!" Lao Tu jumped up, "That's not good, absolutely not!"

Boss Xiong hurriedly asked, "What's the matter, Lao Tu?"

"The city gave me the task that at 10 a.m. the day after tomorrow, the network and response centers of all departments in the city will conduct a network test, and within a week, all departments that have not completed the network transformation will be completed. Lao Tu scratched his head, which had few hairs left, "Half a month later, the test will be completed, and there will be new big moves to be carried out in the city at that time." This is a task, do you understand, old bear, that it must be completed on time!"

"If there is really a defect in the system, even if you can complete the task on time, you will have to rework it if something goes wrong in the future, wouldn't it be more troublesome at that time!" Boss Xiong pressed Lao Tu into the chair, "Think about it again, is this the truth?"

"What do you think!" Lao Tu pushed Boss Xiong away and glared at Liu Xiao, "Let me ask you, how did you know that the system was flawed? Is it your own guess, or is it 100% sure?"

"This ......" Liu Xiao didn't know how to explain this matter, his conclusion was speculated based on Wang Gong's security plan, but he did not contact the so-called response center, and all this was speculation. Liu Xiao thought for a while and said: "These are what I found in the construction according to the actual situation, and they are my speculations, but I am sure, even if I can't be 100% sure, there is an eighty percent possibility." ”

"Construction, what construction?" Lao Tu turned his head to look at Boss Xiong, "Boss Xiong, this can't be the company you introduced, right?"

Boss Xiong nodded, "Exactly!"

"Play the piano!" Lao Tu slapped the table and jumped up, "A person who does wire wiring and wiring systems dares to tell me that there is something wrong with the city government's system, I think you are a human being, and you want me to postpone the project for a baseless speculation of yours, it's ridiculous! Who do you think you are!" You, what should you do, this time I will look at Boss Xiong's face, so I won't bother with you, I have time to go to the hospital for a check-up, damn, neurotic!"

Liu Xiao almost fainted, jumped up and was about to chase out, he had never suffered such a wretched spirit. This is also well-intentioned, if Haicheng was teased by hacker organizations from other countries during the exercise, it would be shameful not for me Liu Xiao himself, but for Haicheng, and also for the shame of the entire country's network security community, and I Liu Xiao had nothing to do with it. Liu Xiao was extremely unhappy, he must chase him out and theorize with that bald head.

Boss Xiong hurriedly grabbed Liu Xiao, "Liu Xiao, you stop for me!"

"I can't stand!" Liu Xiao was furious, "I've never seen such a bully, I must ask him to give me an explanation!"

"I know you're kind!" Boss Xiong stood in front of Liu Xiao, "If Lao Tu doesn't listen, forget it, I'll help you find someone else, there are more people in charge, I don't believe everyone is so confused!"

"No need!" Liu Xiao pushed Boss Xiong away, "I've changed my mind now, even if they beg me, I don't want to say it." ”

"Can you calm down?" Boss Xiong chased after Liu Xiao.

Liu Xiao went out, walked to the door of the bald office, stood at the door, slammed the door twice, and waited for everyone to look over, he pointed to the bald head, and said word by word: "You wait, you will regret it!", and walked away after speaking.

It's just that Boss Xiong suffered, the bald hair soared, and he chased him out to find trouble with Liu Xiao, but he was pressed by Boss Xiong at the door.

In the next two days, Liu Xiao took leave, did not go to work, and hid at home every day, Niu Pengen was afraid that Liu Xiao was going to change jobs, so he called from time to time to care, Liu Xiao said that he was not feeling well and was sleeping.

*****

Haicheng Network Command and Monitoring Center and Emergency Response Center.

Several of the city's main leaders arrived, including the mayor and the bald man surnamed Tu, and everyone sat in a large conference room with a huge LCD screen on the wall.

Wang Gong walked in at this time, walked up to the mayor, and said, "Mayor Zhao, everything is ready!"

"Then let's get started!" Mayor Zhao bowed slightly and gave an order.

"Okay!" Wang Gong nodded, "Then I'll go over there to command!"

As soon as Wang Gong went out, the LCD screen on the wall lit up, and there were a few bright spots on the screen, and the small print next to it showed that these highlights were the network of the response center, which was currently working normally.

Within a minute, the bright spots on the screen began to increase, and the prompts next to them let everyone know that this was the network of various departments, and that any department that had established a connection to the response center would show a bright spot on the screen.

When the bright spots were no longer increasing, Wang Gong walked in again, full of excitement, and said happily: "Report to the mayor, the departments that have completed the network transformation have now successfully established a connection with the response center, and all of them are working normally." In the next stage, we will conduct practical functional tests. ”

"Okay! Great! Thank you for your hard work, congratulations!" Mayor Zhao stood up and took the lead in applauding and congratulating, and the rest of the people also stood up and applauded.

"Mayor Zhao, tell us a few words!" Standing behind Mayor Zhao, he hurriedly proposed while he was bald.

Mayor Zhao bowed his head, "Okay, then I'll just say a few words!" Mayor Zhao stepped down on the LCD screen in front of him and said, "First of all, on behalf of the Haicheng City Government, I would like to thank those who have paid sweat and hard work in this network transformation!"

"All of you here should be able to experience firsthand that today's Internet has been closely related and inseparable from our lives, and at a small level, our lives, communications, entertainment, etc., are inseparable from the Internet; at a large level, a city, a country, and even the whole world, our economy and order must rely on the Internet to support and promote. Therefore, this network transformation of our Haicheng is very meaningful, it is in line with the requirements of the times, it is in line with the needs of Haicheng, and it is ......" Mayor Zhao had not finished his sentence, and he heard the loudspeaker in the conference room scream harshly.

"What's going on?" Mayor Zhao asked with a frown.

Wang Gong looked up at the screen and found that the network logo of a department turned red, flashing in a stiff way, Wang Gong frowned, and said: "The network of the bus department has a bit of a failure, I think it should be that our network has just been connected, and the response center has made an error in the screening of information, the problem is not serious, and it will be good to run in for a while." ”

Mayor Zhao let out an "oh", put his heart back in his stomach, and turned around to look at the screen above his head.

He was amazed at this, and the flickering red dots on the screen suddenly increased, and instantly became more than a dozen. Wang Gong's face changed, and he said, "I'll go over there and have a look." After speaking, he went straight to the door.

Just when Wang Gong went out, the red dots continued to increase, almost doubling, and at this time, there were no normal bright spots on the screen. is a fool, he should also know that something is wrong, Mayor Zhao's face is ugly, and he walked towards the door, he wants to go to the command room and see for himself what happened.

The next room is the command room of the response center, and the walls of the room are covered with hundreds of screens, large and small, each screen shows the network health status of a department, and almost all the screens are flashing around at this time.

"What's the situation?" asked Wang Gong anxiously.

"Wang Gong, the networks of various departments have been attacked by hackers, and there is a tendency to continue to spread, we don't know who the other party is, and we don't know what means he used to attack our network. Someone immediately answered Wang Gong's question.

Wang Gong's head began to sweat, but he was still calm, and said: "Don't panic, everyone, this may be a mistake in our system itself, even if it is really hacked, hackers can't get permission." Wang Gong thought for a while, "Now start the emergency communication plan and contact the communication servers of various departments to confirm whether they have been hacked!"

"Tried!" the man was a little frustrated, "I could get in touch, but no news returned." ”

Wang Gong had an ominous premonition in his heart, could it be that he was really hacked, this hacker is too powerful, the network on our side has just been connected, and he has pinched it over there, what does he want to do?

"No, no!" Wang Gong shook his head again and again, "If you want to invade, then this hacker has already invaded, why do you have to wait until the networks of various departments are connected to the response center, can it be said that his target is the response center?"

Thinking of this, Wang Gong couldn't help but feel a chill in his heart, broke out in a cold sweat, and shouted, "Quickly cut off the connection to the network of various departments!" After speaking, Wang Gong went straight to the command platform, and as soon as his hand touched the keyboard, he saw that the computer screen of the command platform was black, and a line of words popped up on it, "Enter the emergency response state, and after ten minutes, you can return to normal state with the authority password!"

"Bang!" Wang Gong smashed the keyboard with a punch, and the opponent's target was indeed the response center, and now the system of the response center also thought that he was in danger, and then entered a state of emergency, not to mention hackers, even himself, could not make the slightest change to the operation of the system. The worst thing is that the system must now think that all the departments have been hacked, and in order to ensure that the order of the city does not appear disordered, the system may issue a series of contingency measures, and God knows what orders it will issue.

"What the hell is going on?" Mayor Zhao angrily walked in.

Wang Gong looked at the screen and had nothing to say, this response mechanism designed by himself was originally designed to prevent hacker attacks, but now the entire city has been kidnapped, how can he explain it to the mayor.

Liu Xiao was standing in his home at this time, looking out of the window, he saw that the traffic lights at all the intersections had turned red, and all the cars were lying on the road, anxiously waiting for the lights to turn green, who didn't know what was going on now. In less than two minutes, the sirens sounded, and all the police in Haicheng were dispatched and took to the streets to maintain order and prevent riots.

Liu Xiao sighed, even if his vision was blocked by the tall buildings in the distance, he could know that in the distance of those tall buildings, all the chemical plants and power plants had been shut down, all the banks had suspended trading, under the ground, the subway was suspended, and outside the city, the air towers at the airport had also stopped working, and all planes would not be able to take off.

And all of this is the so-called emergency warning mechanism, in order to prevent hackers from malicious destruction of these targets.
