Liu Xiao came to Zhang Xiaohua's house for the third time, the first two times he was very arrogant, but this time he was a little restrained, sitting on the big sofa in the living room and not moving.

Zhang Xiaohua was very unaccustomed to Liu Xiao's change, which made her a little inexplicable, picked up an apple and handed it over, "You eat fruit!"

Liu Xiao just took the apple, but he didn't take his mouth and asked, "When will your father come back?"

Zhang Xiaohua glanced at the clock and said, "It's almost over!" I called him, and he said that he would be back soon. ”

"What the hell is he looking for me?" Liu Xiao asked humbly.

Zhang Xiaohua was happy when she saw it, it turned out that this kid had been worried about this, no wonder he didn't pull it, "Don't worry, my dad won't eat you again!"

"I'm good if I can eat it!" Liu Xiao grabbed the apple and took a bite hatefully.

As soon as the words fell, the doorbell rang, and the nanny Aunt Han ran over to pick up the video phone by the door, and Zhang Chunsheng's figure came out of it, and Aunt Han hurriedly opened the door.

"Liu Xiao's kid is here, right?" Before Zhang Chunsheng entered the door, he asked Aunt Han first, and when he came in and saw Liu Xiao, his laughter got up, and he hurried to Liu Xiao.

Liu Xiao hurriedly stood up, and just as he was about to say hello, he was hugged by Zhang Chunsheng with a bear hug, which made him almost hold his breath.

Zhang Chunsheng let go of his arm, looking very excited, "You kid is here, you counted me down that day, and you were happy when you were done, and as soon as you left, I didn't have a decline in the past few days, I couldn't eat well, and I couldn't sleep well." ”

Liu Xiao could hear it, Zhang Chunsheng said this, but there was no meaning of blame in his words, it seemed that he really figured it out, Liu Xiao was a little embarrassed now, and said: "The kid is young, and he doesn't have a depth of speech, you must not go to your heart!"

"Why are you standing, sit!" Zhang Chunsheng pressed Liu Xiao into the sofa, "How can I blame you, it's too late for me to thank you." When he saw that Liu Xiao only had a cup of tea in front of him, Zhang Chunsheng shouted, "Mother Han, you go and take out my best red robe." ”

Zhang Xiaohua next to her had an opinion, and said to Liu Xiao: "You see how partial my father is, he usually hides those good teas tightly, I can't touch them if I want to." ”

"You dead girl, you know what a good tea is, and you don't want to see a strange thing that spoils my tea leaves for nothing. Zhang Chunsheng scolded with a smile and sat down himself.

Zhang Xiaohua pouted, "Then you know that he understands tea?"

Liu Xiao laughed dryly, he didn't say anything, but it was just a joke.

Zhang Chunsheng looked at Liu Xiao and said with emotion: "My old Zhang's family was poor when he was a child, and he went to other people's houses to do short-term jobs every day. But since I started my career, no one dares to train me with a gun and a stick like that, and you kid is the first one. ”

Liu Xiao coughed, "I ......"

"Don't say anything, I understand Lao Zhang!" Zhang Chunsheng cut off Liu Xiao's words, "Among all these people who have scolded me Lao Zhang, I can hold a grudge, but there are only two people, not only can I not hold a grudge, I also have to thank him." This first one, it's my big brother Chen, if it weren't for his scolding back then, I'm afraid that my old Zhang would have found a short-term and reported to Lord Yama, how could there be a good day today; But you are different, everything you say is a sure fact, and the analysis is also objective and fair, you scolded me Lao Zhang is speechless, and I was convinced. ”

The more Zhang Chunsheng spoke, the more excited he became: "My old Zhang is a little bit of a chicken intestine with a small belly, and his brain is a little confused, but I can still distinguish the good from the bad, you kid didn't treat me as an outsider, it was for my good, so you scolded me." If it was a passerby, he would definitely like to see my jokes, and he couldn't wait to go up and fan the flames again, I just wanted people to scold me, and people were not happy. ”

Liu Xiao panicked for a while, his face was so hot, Zhang Chunsheng blew himself into a flower, but how could he be so noble, he just had an appointment with Zhang Xiaohua in advance, for the 100,000 yuan, Zhang Chunsheng definitely didn't know about this agreement, if he knew, he wouldn't have said so.

Zhang Chunsheng moved to Liu Xiao's side and grabbed Liu Xiao's hand, "I'm so happy, if you don't dislike it, our friend will be considered a friend in the future." ”

Liu Xiao nodded hurriedly, unable to shout any good words in his mouth, and said vigorously: "It's an honor, it's an honor." ”

Zhang Chunsheng was overjoyed and stood up, "Okay, I'll call you Brother Liu in the future!"

"Huh?" Liu Xiao was startled, jumped up, and hurriedly shook his head, "No, no, this is absolutely not good!"

"What?" Zhang Chunsheng was displeased, "You don't like my friend Lao Zhang?"

"No, that's not what I mean!" Liu Xiao waved his hand again and again, "I can't stand your voice, brother, you are two years older than my father, Xiaohua and I are alumni, I still call you Uncle Zhang." If you really call me Brother Liu, then when I see Xiaohua in the future, won't I take advantage of her. ”

Zhang Xiaohua next to her finally opened her mouth, "Dad, why are you like this, you call everyone a brother." It's long time since I don't like this, do you still want to rub the grass for incense and tie the knot Jinlan!"

Zhang Chunsheng smiled awkwardly, "I'm a little excited, since you young people don't like this, then follow yours, follow yours." ”

Everyone sat down again, Zhang Chunsheng looked at Liu Xiao and said: "Liu Xiao, I have thought about it carefully in the past few days, and I think that I should move the computer back to the company again. As for the ferrying attack you talked about last time, they don't seem to have any effective solutions, I think about it, I have to discuss this matter with you, I think you are better than them. ”

Liu Xiao smiled a little embarrassedly, "Actually, I also lied that day, this kind of ferry attack is not a normal hacking method, so far, only some very professional cyber spies will use this method, this technology is difficult to master, and the general security company does not understand this method, so there is no good way to prevent it." ”

"Then do you have anything you can do?" asked Zhang Chunsheng, who was more concerned about the issue.

"Actually, it's just to guard against ferry attacks, which is very easy to do!"

Zhang Chunsheng was overjoyed, "I knew I could find you!"

Liu Xiao shook his head, "I don't mean this, I mean, if you really move the computer and network back to the company, you may face more than just a ferry attack, on the Internet, hackers have more diverse attack methods, and sometimes it is really difficult to prevent." I'll give you an example, if we have now prevented the ferry attack, then the hackers will naturally change their methods, I see that many people in the company's address book have EMAIL, and some employees even have their own EMAIL addresses printed on business cards, these things should not belong to any secrets, right?"

Zhang Chunsheng nodded, and he saw that Secretary Xiao Li's business card seemed to have this EMAIL.

"IN OUR OPINION, EMAIL IS JUST A MEANS OF COMMUNICATION, AND IT HAS NO VALUE IN ITSELF, BUT IN THE EYES OF HACKERS, THESE EMAILS ARE SIMPLY A ****, AND HE CAN DO A LOT OF TRICKS ON THIS EMAIL. FIRST, HE GOT YOUR EMAIL ADDRESS, AND USED BRUTE FORCE GUESSING TO CRACK OUT YOUR EMAIL PASSWORD, SO THAT HE COULD EASILY GET ALL THE INFORMATION IN YOUR MAILBOX; SECOND, IF THERE IS NO VALUABLE INFORMATION IN YOUR MAILBOX, IT DOESN'T MATTER, HE CAN FIND THE EMAIL OF YOUR CUSTOMER OR COLLEAGUE FROM THE RECORD OF YOUR SENDING AND RECEIVING EMAILS, SO THAT HE MAY GET THE INFORMATION IN THESE EMAILS, AND BY EXTENSION, HE WILL ALSO GET THE INFORMATION OF YOUR COLLEAGUES' COLLEAGUES; THIRD, SOME HACKERS WITH MORE SOPHISTICATED MEANS, AFTER HE KNOWS YOUR EMAIL, HE CAN IMPERSONATE YOUR EMAIL TO SEND EMAILS TO YOUR COLLEAGUES OR SUBORDINATESOnce the email is received, the Trojan horse will be installed on the computer, waiting for the opportunity to steal the data. ”

Zhang Chunsheng's face was a little green, according to Liu Xiao, the computer would not work.

Liu Xiao hurriedly said his subject, " Therefore, in order to fundamentally prevent hacker intrusion, first, it is necessary to improve the quality of employees, enhance their security awareness, develop good security habits, and reduce the ways of leaking information as much as possible; second, establish a complete enterprise network security system, install anti-virus software and anti-espionage programs, and appoint professional security personnel to be responsible for maintenance, so as to make 24-hour anti-intrusion preparations; third, divide the level of enterprise information, configure information according to authority, increase the difficulty of hackers stealing confidential information, and do a good job of encrypting enterprise information in the process of preservation and transmission, so that even if hackers steal information, they will not be able to decipher the true content of information。 ”

"Okay, good, great!" Zhang Chunsheng patted his thigh fiercely, still the same sentence, "I knew you kid was good! Hearing you say this, I have the bottom in my heart, you are much better than those people in professional companies, and you can say this point at once." ”

Liu Xiao smiled, "Uncle Zhang, don't be too happy, although what I said can basically prevent invasion, but to fully realize it, it requires a lot of funds and manpower, and it is not like spending millions casually like last time, and then everyone can solve it with a computer." ”

"What are you afraid of spending some money!" Zhang Chunsheng waved his hand, looking wealthy, but he still asked very cautiously, "How much do you roughly estimate?"

"I don't really know about that, but I estimate it will be at least around 20 million, and you have to talk to the security companies about the exact number. ”

After Zhang Chunsheng heard this number, he began to calculate in his heart, businessman, just like that, you have to calculate the costs and benefits.

Zhang Xiaohua couldn't get used to her father's old money fan, and said: "Dad, you still have to think about 20 million, you won't lose money, don't worry!"

Liu Xiao looked at Zhang Chunsheng, "20 million is not a small amount, but I personally think that investing this money in the construction of the company's network and information system is absolutely worth it, which is a development trend." Just as we usually see the news of a plane crash on the news, we cannot deny that the plane is still the safest and fastest way of transmission among all means of transportation. This is very similar to the network, the hacker intrusion, did not stop those large enterprises to do everything to engage in their own network construction, because they know very well that this is a future investment. ”

"Yes, yes!" Zhang Xiaohua nodded again and again, pushing Zhang Chunsheng, "No one is a fool, you see those companies that are much bigger than our Zhang family, they are all shrewd to death, why do they have to spend money desperately on the Internet." ”

Zhang Chunsheng still didn't seem to be able to pay attention, muttered for a long time, and said: "Since you want to do it, you have to do it well, you have to have a comprehensive consideration, let me plan again!"

Zhang Chunsheng no longer rejects computers, and Liu Xiao's task is completed, as for Zhang Chunsheng's investment problem, it is not something that Liu Xiao can manage, so he no longer persuades him.

Zhang Xiaohua didn't give up, and continued to mumble for a while, but Zhang Chunsheng didn't agree happily when he arrived, and this matter ended here. Zhang Chunsheng left Liu Xiao to eat at home, and the two killed two more games of chess, and it was very late to see that Zhang Chunsheng had to put down the chess pieces, make an appointment to fight again next time, and then asked the driver to send Liu Xiao back.
