Zhang Gong took Liao Gong's words and said: "We had an information loss incident before, and the information was taken from the external equipment such as the USB flash drive, so we customized a new chassis, which did not hinder the normal use of the employees. We are also strictly selected in computer accessories, and all accessories with wireless transmission function are not purchased. There is also an electronic lock on this chassis, which can be connected to the motherboard, and the situation of the electronic lock is displayed on our monitoring system, if anyone has touched the lock, we can find out! ”

Hu Yifei was completely stupid, he had never been exposed to anything in this area before, judging from his cognitive level, this was already safe enough, no, it was absolutely safe!

"There's only one place in the company where computers can be connected to external devices, and that's the print room!" Liao Gong smiled, "However, we have also done processing on the computer there, even if it is connected to an external device, it can only transmit the data from the external device to the printer, but it cannot write any data to the external device!" ”

"There is also a system in the printing room, all printed things have serial numbers, and employees have to register the serial number and printed content with their own employee cards when printing. Every day before leaving work at the latest, we will do an inventory of the whereabouts of these printed documents, and the documents that need to be destroyed will be destroyed after verification, and then the serial number of the documents will be cancelled; Documents that need to be archived are stored in the database with serial numbers that are retained until they are destroyed or invalidated. If a document is lost, we will investigate it in a timely manner based on the registered employee card number! ”

Zhang Gong added at this time, "The access control system will have the information of these employees, and they are not allowed to leave the company until the documents are transferred, archived, and destroyed." ”

Hu Yifei was about to say this, but he didn't expect people to think of it a long time ago, but after thinking about it, he felt that the document could be taken out of the company by printing it out and others taking it with their mobile phones.

"What I just said is mainly for some ordinary administrative documents that are said to be in the work, and we have another system for confidential documents, which is stricter than this!" Liao Gong smiled, as if he saw Hu Yifei's thoughts.

Hu Yifei was frustrated, he had nothing to say, today was really an eye-opener, he originally thought that network security and information security were anti-hacker and anti-virus, but he didn't expect that it could include so many things, Jinlong Pharmaceutical was even stronger than anti-foreign thieves in terms of preventing thieves.

The two took Hu Yifei to visit the office area of the administrative building and took him to the test building. This is the place to study the prescription and analyze the surname of the medicine, Hu Yifei saw a lot of mice here, of course, there are more cameras, and the system here in the test building is stricter, not to mention taking the documents out, it is impossible to take a small piece of paper out.

Because it was a controlled area, the three of them could only watch it for a while, and Hu Yifei did not find any place to use.

Back in the previous office, Zeng Xuanli was already sitting there waiting, and when she saw Hu Yifei, she asked with a smile: "How is it, Expert Hu, have you found anything that needs to be improved?" ”

Hu Yifei had a black face, Zeng Xuanli's expression was obviously schadenfreude, she arranged for the two of them to take her to visit, and Bacheng wanted to see her jokes. However, he still admired the safety of Jinlong Pharmaceutical, and said: "Your systems and measures are very good, I took a cursory look and found nothing!" ”

"Well, what I saw just now is all superficial things!" Zhang Gong echoed on the side, "Whether there is a safety risk depends on the specific details of the system!" ”

Hu Yifei has read the security system information given by COBRA and knows that in order to verify whether the security system of the enterprise is risky, it is very important to analyze the loopholes in the details of the system, but these system details are the foundation of people's security, and they must sign a series of agreements and get authorization before the security agency can get it.

"You're safe here, I don't think there's anything to improve!" Hu Yifei looked at Zeng Xuanli, "Then I'll go back first!" He originally planned to pretend, but after a trip just now, he didn't even have the courage to pretend, and there were two experts standing here, and he would definitely have to show his stuff as soon as he made a move.

"Don't worry!" Zeng Xuanli stood up, "I came to you today, not to let you find the loopholes of those superficial things, but there are specific things that you need to analyze and analyze!" ”

Hu Yifei glared at Zeng Xuanli unhappily, this girl really plans to play with herself, before turning just now, why didn't you say that there were specific things to analyze, and after a big turn, Lao Tzu's confidence was gone, so you said specific things.

"Yes!" Zhang Gong began to echo again, "That's right, last month, there were two hacking incidents in our Jinlong Pharmaceutical Co., Ltd. The first time, the hacker bypassed our firewall and was then discovered by our intrusion detection system; But soon, the hackers also got the intrusion detection system together, but when they finally stole the data, they were discovered by our data monitoring system, and they didn't let him succeed. After the incident, we changed the password of the firewall and upgraded the intrusion detection system, but we still have no traces left by the hackers, and we don't know what exactly happened to the vulnerability, so that they succeeded in the invasion three times and twice. Zhang Gong smiled after speaking, "This will have to trouble Expert Hu!" ”

Hu Yifei had a headache, you veterans can't find clues, Lao Tzu is a novice, a hunter who has only studied for two weeks, how can he find clues, Zeng Xuanli laughed on the side: "Hu Yi...... Expert Hu, now that the matter has been made clear, you won't say that you can't do it, right? ”

Hu Yifei has the mind to strangle Zeng Xuanli to death, this girl just wants Lao Tzu to be soft, Lao Tzu, I don't want to, a big man, if I am wrong, I will be wrong to the end, I would rather humiliate you than say half a word. Hu Yifei gritted his teeth at the moment, "Okay, I'll help you take a look!" ”

Zhang Gong and Liao Gong were happy, but Zeng Xuanli looked like he was falling through glasses, and said in his heart that Hu Yifei was really a cow, and he would not turn back if he did not hit the south wall.

Hu Yifei recalled the hunter knowledge he had learned these days, and said, "I'm going to go to your server first and see if I can find any clues!" ”

Zhang Gong and Liao Gong went to see Zeng Xuanli, and when he saw Zeng Xuanli nodding, he said, "Okay, I'll take Expert Hu over to have a look!" ”

The four of them were divided into three echelons, and each entered the switchboard room with their own hearts.

Zhang Gong pointed to a running machine and said, "This is the server!" After finishing a point, he pointed to a chassis on the ground and said, "This is the second time that hackers have come in and tried to steal the computer, and we have also moved here." ”

Hu Yifei stepped forward and successfully opened the server's Yue Zhi, the first step was successfully completed, and he couldn't help but breathe a sigh of relief, if he couldn't find where the Yue Zhi was, he turned around and asked what day the hacker invasion was, and he found the Yue Zhi of that day, but it was empty, and the Yue Zhi had already been cleared. He went to a few other places where he might leave traces and looked at it, but he didn't find anything, Hu Yifei was face black at that time, and the hunter knowledge he had learned so far was limited to this level, and he hadn't touched it yet.

"Is the data unpacking done?" Hu Yifei pretended to be very expert and asked.

"It's done! No, no way to determine how the other party got in! Liao Gong replied, wondering in his heart, this Hu expert's methods are very ordinary, and he didn't find anything special.

Hu Yifei thought about it, buckled the cord in his pocket for a while, took out the USB flash drive, and said, "I have a few more professional scanners here, let's scan the server first!" Hu Yifei is the best at this, if you don't use it at this time, you can only invalidate it.

Zhang Gong stepped forward to take it, but it was plugged into another machine and said, "Just use this machine to scan!" ”

Hu Yifei went over and pulled out all the scanners he usually used, asked the IP, and started scanning.

Zhang Gong and Liao Gong glanced at each other, and said that they had already scanned these scanners several times, and the server did not have any security vulnerabilities. The two wanted to tell Hu Yifei that this was useless, but when they saw Zeng Xuanli observing Hu Yifei's actions with interest on the side, the two had to shake their heads and give up, thinking that they would observe patiently for a while to see where this Hu expert's "brick" was hidden.

Hu Yifei finished scanning one and didn't find it, so he changed to another scanner.

At this time, Liao Gong couldn't help it, and stepped forward and said: "What, Expert Hu, the version of your scanner is a bit old, I have the latest version here, and the scanning information is more comprehensive!" With that, he clicked on the machine and pulled out an identical scanner.

"Giggle......!" Zeng Xuanli couldn't hold it back anymore at this time, and covered his stomach with laughter, Hu Yifei is so funny, this is all oolong home, even if you pretend to be an expert, you can pretend to be professional anyway, and even use an outdated tool to fool people.

Hu Yifei's face turned red, and he stood there for a long time without speaking, looking annoyed and angry.

Zhang Gong and Liao Gong on the side were completely confused, and they didn't know what tricks these two people were doing.

"Hu ...... Hu Yifei! Zeng Xuanli couldn't breathe with laughter, "You just ...... That's it......"

Before she finished speaking, Hu Yifei had already exploded, "rubbed" and pulled out his USB flash drive, and said, "Do you think your network is very safe?" I just don't want to embarrass you, and with security measures like yours, I have a hundred ways to take your information without you noticing! After speaking, Hu Yifei snorted coldly, turned around and walked out of the computer room.

Zeng Xuanli was dumbfounded, hurriedly chased out, and shouted: "Hu Yifei, don't be so stingy, okay, I'm just teasing you, just kidding!" ”

Hu Yifei stopped, turned around and said coldly: "I'm not joking!" Come to me this time next week, and I'll show you how vulnerable your internet is here! ”

"Then I'll send you back!" Zeng Xuanli shouted in the back, but saw that Hu Yifei didn't look back, and walked out of the gate of Jinlong Pharmaceutical.

"It's stingy!" Zeng Xuanli said in a low voice, pouting, she just thought that Hu Yifei's appearance of the cow was very funny, but she didn't expect it to really him off.
