Chapter 81: Introduction to the Book

After dinner, Hu Yifei returned to the Cybersecurity Department and continued to rush those IPs. When he went out, he hung the 10 IPs there and continued to scan, and now there should be results.

The security guards despise him even more. They even had to stay in the office for lunch break. In the future, they wanted to touch the computer on weekends, and there was basically no hope.

Back in the office, Hu Yifei sorted out the scanned results and hung up ten more IPs, feeling sad. At this rate, he could get 20 IPs a day, 40 for two days, and 40 for one month, and four weekends in January. He could get all of them, and he could only get 160 IPs. There were three or four hundred IPs on this paper, and Xiaoqiang's brother didn't say when he finished it. He couldn't finish the two-month internship, so he just did this thing. Scan - excerpt - sort - scan again. If you repeat this, you will sooner or later become crazy.

Hu Yifei was not stupid enough to wait for the result after hanging up those ten IPs. He turned on the Internet and saw what was on Weilan's LAN. The Network Security Department had two machines online at this time, one was in front of him, and the other was not sure where it was. Anyway, the office was no longer on computers.

Hu Yifei tried to open the computer, but it opened it as soon as he clicked it. It was all shared information, all about security. The two materials given by Cobra in Hu Yifei's hand also included them.

In addition to the information, there are cases and various cases. Hu Yifei clicked and read several copies and found that the authors of the cases were all cobra. It seems that these cases were accumulated over the years. The cases in them are big and small. The small ones are the settings of personal computer security policies, and the large ones are the enterprise network with thousands of machines and the construction of the security system of the agency network.

"These are all experiences, it's best to take a look!" Hu Yifei thought, and copied ten simple cases, stuffed them into the USB drive he brought, and prepared to go back and study them carefully.

If you look at the information carefully, there is a folder full of Cobra's notes and thoughts. In addition, there is a complete lesson plan called "Cybersecurity Engineer Starting from Scratch to Beginner's Proficiency".

Hu Yifei was overjoyed and quickly copied the lesson plan. After reading two pages, he could understand it completely. It was really starting from scratch. Hu Yifei made an appraisal conclusion for this lesson plan: Baby! After that, he quickly stuffed it into his USB flash drive, thinking that this was probably the tutorial Cobra gave to the training class of Fatty Yan, the network security teacher. It was really cheap. He didn't pay a penny and saw it all.

"I didn't expect that cobra has a problem with the owner of the second-hand hard drive. He likes to write notes and experiences. This is probably a problem that only experts have!" Hu Yifei sighed and opened the lesson plan again and slowly started reading.

Cobra's tutorial is written in detail. It explains in detail what network security is and what it does; then introduces the development process of network security, representative figures and representative technologies; finally, back to the topic, point out where to start with learning network security, what matters should be paid attention to, what knowledge to master, and what abilities to possess.

After reading these, Hu Yifei has already gained a general understanding of network security. At least he knows what the real network security looks like, abandons some fantasies in his previous heart, and corrects some unrealistic mistakes.

Further down, there are specific technical tutorials, which also start with introductory knowledge. Hu Yifei, after all, studied computer science and read it in one go without any obstacles. It seems that Cobra has taken a lot of effort to write this lesson plan. It may be specially prepared for students from these colleges and universities. While getting started, he can also consolidate and re-learn basic knowledge.

Hu Yifei finally found something to do. After tucking the IP, he looked at the lesson plan. After scanning, he sorted it out and continued to read the tutorial. He has always been a hacker who has been learning from all over the place and cannot get a single point. Cobra's tutorial gave him a feeling of being done in one go and integrating it. The materials and knowledge he had read in pieces before were gradually connected and summarized together in the process of learning the lesson plan.

In the middle, the security guards ran over to see him several times, but once they saw him, they were disappointed. Hu Yifei seemed to be on the chair, and he didn't move a nest for the whole afternoon and didn't see him in the toilet. He had never seen such shameless people. He didn't treat himself as a human for 500 yuan.

"Beast!" The security guards cursed and turned around and left. After less than half an hour, they came to scold again.

When he was about to get off work in the afternoon, Hu Yifei finally finished 20 IPs. Seeing that there was still some time, he got ten more. He was very happy to read the lesson plan, so it wouldn't matter if he was delayed for a while.

This made the security guards worried. They had been looking forward to it for a long time, but they didn't touch the computer all day. They were so numb, their feet, and their stomachs were cramped. Anyway, they felt uncomfortable all over. If they couldn't touch the computer today, it would be my turn to rest on the weekend next time, but I don't know when it will be.

Seeing that Hu Yifei had not left after get off work, the security guards knocked on the door of the Cybersecurity Department again and reminded with a smile: "Mr. Hu, it's time to get off work!"

"Well, I know!" Hu Yifei looked at the tutorial without raising his eyes. "There is something on his hands, and he will leave after he finishes!"

The security guard scolded in his heart, "Damn it, this Cyber ​​Security Department is the most idle department in the entire building. It is the late one and the earliest to get off work. I have never seen anyone come in on weekends. Why does an intern change the weather when he comes, and he is too busy to finish his work and has to work overtime. Isn't this a weird thing? The two security guards immediately looked at each other and said, "That's right, we have to hand over the shift later, so we have to close the building door in advance..."

Hu Yifei knew at a glance that the two security guards were bullying him and were newcomers, and said, "Do you have to drive out the entire building when you hand over the shift?"

The two security guards were stunned. Although this kid was young, he was not easy to deal with. He was immediately covered in dirt and prepared to retreat. It seemed that there was no chance to touch the computer.

"Do you want to play games?" Hu Yifei suddenly asked. The two security guards had traveled so many times in the afternoon, and now they are urging themselves to get off work. No matter how stupid he is, he can guess what it is.

The two security guards shook their heads and waved their hands, "No, no, we have regulations, we cannot enter the work area without permission, and we cannot move office supplies, especially computers."

Hu Yifei was not a fool, and said, "Will no one discover you playing games here?"

"We came to turn off the computer in the morning. So, save electricity and eliminate waste!" A security guard looked so slick.

Another one followed and said: "Yes, stop wasting! Waste is shameful!"

Hu Yifei laughed, "It doesn't matter if you don't tell the truth. I will report to the General Officer tomorrow about you playing games here!"

"Don't let it go, don't let it go!" The security guard was anxious and walked a few steps closer. The guy with a slick head gritted his teeth and said, "Little brother, let me tell you this, that is, you, the newcomer, take this place seriously. In fact, in this building, no one knows that the Cyber ​​Security Department is a barren land to put it bluntly, and birds don't come to shit!"

"Yes, barren land!" Another security guard always likes to repeat other people's words, and especially likes to use a emphasized tone.

"What's going on? Tell me!" Hu Yifei came twice, and every time he felt that the Cyber ​​Security Department was a little strange. Now when he heard the security guard say this, it seems that there is really a problem.

"Well, when I was working as a security guard in this building, I heard that the Cyber ​​Security Department is known as a 'one-person department'. Except for Director Hui who is a character, everything else is waste!" The security guard said, and looked at Hu Yifei and said strangely: "You just came in, it's not counting!"

"What kind of waste? Do you understand? That's called a royal relative!" The security guard who likes to repeat other people's words will not repeat this time, saying, "My brother-in-law has been a security guard here for five years. He knows best. He said that the people in this cybersecurity department are relatives of the chairman and the president. You know, the fat man who smiles all day long, he is the president's brother-in-law!" The security brother-in-law mentioned the president's brother-in-law with envy. The difference between them is too big.

"It's obviously a waste! Last time in the monitoring room, I saw those guys being scolded by Director Hui. If he was really a brother-in-law, would Director Hui dare to scold him and try?"

The two security guards started arguing one by one, and they said it was a place for raising waste, and their brother-in-law said it was a place for raising relatives in the royal family. They each raised the facts and finally picked up the intercom and prepared to call someone to testify for themselves.

Hu Yifei's head hurts. Damn, it seems that this Cyber ​​Security Department is really a place of trouble. It seems that it is not very wise to come here for an internship by himself.

"Stop quarrel!" Hu Yifei pulled away the two security guards, "How long have you been playing games here?"

"Anyway, when I came in here as a security guard, everyone came here to play games in the evening and weekends! That game was still made by those wastes themselves!"

"No, my brother-in-law was already starting when he was working as a security guard here!"

Hu Yifei had a headache. Damn, that is to say, the security guards have regarded this as an Internet cafe for at least five years. Cobra is a security master. How come he has not noticed the security guards' actions for so long? He must have turned a blind eye and pretended that he had not found it. He didn't even find it. He might have deliberately indulged it. He was just internship here, so he didn't violate other people's rules, and he just thought that he hadn't seen it.

"Okay, I understand!" Hu Yifei pulled the two security guards who were pushing each other away, "Then I'll get off work, you guys continue, I'll come tomorrow, you just think I don't exist!"

After Hu Yifei finished speaking, he packed up the machine and turned it off, and took his USB flash drive and materials out.

The two security guards stood stupidly for a long time before they understood what Hu Yifei meant. They each grabbed a machine and continued to fight the interstellar world, thinking that they had to make up for the things they hadn't played during the day at night.

"I said, that intern is so righteous!"

"Yes, it's so righteous!" With the computer, the security guard began to emphasize again.
