After eating, Hu Yifei went back to the network security department, and continued to dump those IPs, and when he went out, he hung the 10 IPs there to continue scanning, and now there should be results.

The security guards despised his behavior even more, and even had to stay in the office during the lunch break, and it was basically hopeless to try to touch the computer on weekends in the future.

Back in the office, Hu Yifei sorted out the scanned results, and hung ten IPs on it, his heart was full of sorrow, according to this speed, he could get 20 IPs in one day, 40 in two days, and four weekends in a month, and he could only get 160 IPs if he did all this. There are three or four hundred IPs on this paper, and Xiaoqiang's brother didn't say when he would finish it, he can't do a two-month internship, so he just does this one thing. Scanning, excerpting, sorting, scanning, and so on, and sooner or later you will go crazy.

Hang up the ten IPs, Hu Yifei is not stupid to wait for the result, open the network, see what is on the LAN of Weilan Company, the network security department has two machines online at this time, one is in front of him, and the other is not known where, anyway, there is no computer in the office is lit.

Hu Yifei tried to open the computer, but it opened with one click, and it was full of shared information, all about security, and the two materials given by Cobra in Hu Yifei's hand were also there.

In addition to the information, it is a case, a variety of cases, Hu Yifei clicked on a few copies, and found that the authors of the cases are all cobra, it seems that these cases are accumulated by him for many years, the cases in it are large and small, the small ones are the personal computer security policy settings, and the big ones are the security system construction of enterprise networks and organ networks with thousands of machines.

"These are all experiences, and it's better to see them!" Hu Yifei thought about it, so he copied ten simple cases, stuffed them into the USB flash drive he brought, and prepared to go back and study them carefully.

Looking at the materials again, there is a folder full of Cobra's notes and experiences, in addition, there is a complete lesson plan called "Cyber Security Engineers from Scratch to Beginner Mastery".

Hu Yifei was overjoyed, quickly copied this lesson plan, opened it and read two pages, it was completely understandable, and it was really starting from scratch, Hu Yifei made an appraisal conclusion for this lesson plan: Baby! After finishing it, I quickly stuffed it into my own USB flash drive, thinking that this was probably the tutorial that COBRA did for Yan Fatzi's network security division training class, but it was really cheap, and I didn't pay a dime, so I saw it all.

"I didn't expect Cobra to have a problem with the owner of the second-hand hard drive, and I like to write notes, which is probably a problem that only masters have!" , Hu Yifei sighed with emotion, reopened the lesson plan, and slowly read it.

Cobra's tutorial is very detailed, explaining in detail what cybersecurity is and what it does. Then, the development process of network security was introduced, and the representative figures and technologies were introduced. Finally, back to the topic, he pointed out where to start with learning network security, what matters to pay attention to, what knowledge to master, and what abilities to have.

After reading this, Hu Yifei already has a general understanding of network security, at least he knows what real network security looks like, abandons some illusions in his previous heart, and corrects some unrealistic mistakes.

Further down, there are specific technical tutorials, which also start with introductory knowledge. After all, Hu Yifei is studying computers, and he looked into it at once, without the slightest obstacle, it seems that Cobra has also taken a lot of painstaking effort to write this lesson plan, which may be specially prepared for students in these colleges and universities.

Hu Yifei finally found something to do, and after hanging up the IP, he looked at the lesson plan, sorted it out a little after the scanning, and continued to read the tutorial when it was over. For a long time, he has been learning hacking, and he can't grasp the main point, and this tutorial of Cobra gives him a feeling of being done in one go and comprehending, and the materials and knowledge that he has seen in bits and pieces before are slowly connected and summarized together in the process of learning lesson plans.

In the middle, the security guards ran over to see it several times, and they were disappointed once they saw it, Hu Yifei was like growing on the chair, he didn't move a nest all afternoon, and he didn't go to the toilet, so he had never seen such a shameless person, and he didn't treat himself as a person for 500 yuan.

"Brute!" The security guards cursed, turned and left, and after less than half an hour, they cursed again.

When he was about to get off work in the afternoon, Hu Yifei finally finished 20 IPs, and to see that there was still a little time, he hung up another ten.

This can make those security guards worried, looking forward to it for a long time, but I haven't touched the computer all day, it's really numb, soft and weak, and my stomach cramps, anyway, it's uncomfortable all over my body, if I can't touch the computer today, wait for the next time it's my turn to rest on the weekend, but I don't know when.

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

"Yes, I know!" Hu Yifei looked at the tutorial and didn't raise his eyes, "There is still something on my hands, I will leave when I am done!" ”

The security guard scolded in his heart, the dog said, this network security department is the most idle department in the whole building, the latest to work, the earliest to get off work, I have never seen anyone come in on weekends, why did an intern change the day, the work is too busy to finish, and I have to work overtime, this is not an evil door. Immediately, the two security guards looked at each other and said, "That's the case, we will take over the shift in a while, so we have to close the door of the building in advance......"

Hu Yifei knew at a glance that the two security guards were bullying themselves as newcomers, and said, "Usually, when you take over the shift, you also have to drive out the people in this entire building?" ”

The two security guards were dumbfounded, although this kid is tender, but it is not easy to deal with, immediately discouraged, ready to retreat, it seems that touching the computer is no fun.

"Do you want to play games?" Hu Yifei suddenly asked, the two security guards ran 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 the smell is.

The two security guards shook their heads and waved their hands, "No, no, we have regulations, we can't trespass into the work area, let alone use office supplies, especially computers." ”

Hu Yifei is not a fool, and said: "You guys are playing games here, and no one can find out?" ”

"We're here to turn off the computer in the morning, what, save electricity, and eliminate waste!" A security guard looks like he's slick on the face.

Another followed: "Yes, no waste!" Shame on waste! ”

Hu Yifei laughed, "It doesn't matter if you don't tell the truth, I'll report to the general director tomorrow about your game here!" ”

"Don't mind, don't mind!" The security guard was anxious and took a few steps closer, and the oily guy gritted his teeth and said, "Little brother, let me tell you this, that is, you are a newcomer, so you take this place seriously." In fact, in this building, who doesn't know, this cyber security department is, to put it bluntly, a barren land, and birds don't come to! ”

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

"What's going on? Tell me about it! "Hu Yifei came twice, and each time he felt that the cyber security department was a little strange, and now listening to what the security guard said, it seems that there is really a problem.

"Well, when I entered this building as a security guard, I heard that this network security department is known as a 'one-person department', except for that Director Hui is a character, the others are waste!" The security guard said, glanced at Hu Yifei, and said strangely: "You just came in, it's not counted!" ”

"What waste? Do you understand, that's called a relative of the emperor! The security guard who likes to repeat other people's words will not repeat this time, and said: "My brother-in-law has been a security guard here for five years, and he knows best, he said that the people in this network security department are all relatives of the chairman and president." That fat man who smiles all day long, you know, he is the president's brother-in-law! When the security guard's brother-in-law mentioned the president's brother-in-law, he was envious, and the gap was too big.

"It's rubbish! Last time in the monitoring room, I saw those guys being scolded by Director Hui so bloody, if it was really a brother-in-law, Director Hui dared to scold and try? ”

The two security guards quarreled with each other, and the oily head said that this is a place to raise waste, and the brother-in-law said that this is a place to support the emperor's relatives and relatives, and the two of them each cited the facts and argued, and finally picked up the walkie-talkie, ready to call someone to testify for themselves.

Hu Yifei's brain hurts, damn, it seems that this network security department is really a place of right and wrong, and it doesn't seem very wise to come here for an internship by yourself.

"Stop arguing!" 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, people came here to play games in the evenings and on weekends! The game is still the garbage that installed it itself! ”

"No, my brother-in-law started when he was a security guard here!"

Hu Yifei has even more headaches, damn, that is to say, the security guards have been using this place as an Internet café for at least five years. Cobra is a security master, how can he not find out about the actions of the security guards for so long, he must have turned a blind eye, as if he didn't find it, the door chain is not there, maybe he is still deliberately indulgent, he is just an intern here, and he can't break the rules of others, and he just treats it as if he didn't see it.

"Okay, I got it!" Hu Yifei dragged the two security guards who were together again, "Then I'll get off work, you continue, I'll come back tomorrow, you just don't exist when I don't exist!" ”

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

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

"I said, that intern is really righteous!"

"Yes, that's right!" With the computer, the security guard began to repeat the emphasis again.
