Gao Ming turned around and wrote his name on the whiteboard with a pen, the words were a little scribbled, but Gao Ming didn't take it seriously, and those who learned computers used the keyboard to speak.

    "I am your teacher. In the future, I will teach the course "Cybersecurity". Now, let's take a lesson. ”

    The audience was silent, and everyone did not wake up from the shocking scene in front of them.

    "Oh buy ga, how can he be a teacher?" It's dead, it's dead. A girl covered her head with a surprised face.

    Silence, stagnant silence.

    After the silence, it's boiling.

    "Dude, don't be funny, hurry down, today is 8 months before April Fool's Day." A boy in a T-shirt shouted from below.

    "That's it, buddy, you don't even take the book, pretend to be that teacher, hurry up, there's an empty seat here." "There are people below who are coaxing together, there are many cases of senior brothers and sisters in the university fooling younger brothers and sisters like this, they are not those random freshmen.

    ……

    "I'm not kidding you. Gao Ming knocked on the podium.

    "Then you bring us your teacher card, staff card and the like, otherwise, don't blame us for beating you out as a liar." A boy in a tight vest, showing off his strong muscles, stood up and pointed at Gao Ming.

    To be honest, although Chujiang University is just an ordinary book, the new teachers who can go to the podium must at least have a master's degree, a master's degree, how can ordinary people be more than 20 years old, but Gao Ming looks only about 20. In terms of physiognomy, it really doesn't look like it.

    Gao Ming glanced at him, this is a classroom, not a meeting of the underworld, it seems that they really need me to re-educate.

    "You'll have to go to the HR office for this, all my information is with them." Gao Ming can only express regret, as a newcomer, he is also helpless.

    "Well, the school's Taoism is quite familiar, isn't it, no, just get out of here, don't stick green onions in the pig's nose there - pretend to be an elephant." ”

    The acne man who spoke was even more arrogant, digging his nostrils with one hand and hugging his girlfriend who was dressed extremely coolly with the other, giving people the overall feeling of two words - "arrogant".

    On a hot day, he was still wearing a small suit with three-quarter sleeves, Armani's, this brand Gao Ming knows. is not only arrogant, but also pretending to be forced, Gao Ming gave him a new definition.

    Men who love to pretend to be forced are generally not very men, and Gao Ming is the most unhappy with such people.

    "Whether you believe it or not, I'm here, I won't leave, I won't leave, if you don't believe it, you can leave this classroom now, and this classmate, this is a classroom, not a hotel, if you can't wait, you can go out and do what you love first, I don't remember your absence." Gao Ming said unceremoniously.

    "Who do you think you are?" What do I like to do, what do you care? The acne man stood up and pointed at Gao Ming and scolded.

    "Classmate, just because you don't respect the teacher, I can deduct your usual conduct points, and I will also revise the exam. ”

    Gao Ming has never been afraid of threats, and he picked up the most commonly used nuclear stick of the teacher, especially such a guy who dares to pretend to be with the teacher.

    "You kid have to say it again? You're really thinking of yourself as a green onion. The acne man's face was full of acne, and he had never met a kid in the class who dared to argue with him like this, even if it was really a teacher.

     "Okay, don't make any noise, are you our teacher, let's take the exam." Li Shengnan stood up and said.

    Wearing a sundress and denim shorts, Li Shengnan has a pair of long legs that women envy, and the man's straight eyes are longer than the desk in front of him. The whole classroom couldn't help but light up.

    Li Shengnan is obviously very authoritative in the class, as soon as she said this, the whole class fell silent, even the acne man didn't speak, pointed and mingled, and sat down again.

    "Oh, how do you want to take the test?" Gao Ming raised his eyebrows, the corners of his mouth rose, and he was dismissed by the students in the first class, which was a little fresh.

    "Since you are the teacher who taught us "Cybersecurity", you can first tell us about the core issues of cybersecurity, and let us understand before learning this course. ”

    "Do other students have any questions?" Gao Ming looked around.

    "No"," only a few people answered.

    "The core problem of cybersecurity is that there is no security. ”

    The whole class fell into a deathly silence again, if this is really the teacher, it is too, to give us the course of cyber security, but to tell us that we are not safe.

    The corners of Gao Ming's mouth rose again, obviously satisfied with the effect of his words, which were a bit earth-shattering for the students.

    "If you think that if you learn network security, you can have the ability to ensure that your network is secure, then you are very wrong, because with our current physical communication structure and protocol system and operating system, no matter how you prevent it, there will always be a large number of vulnerabilities for hackers to invade.

    It's like if you wear a piece of clothing that is not of the same quality, today you find a hole, you can patch it, but in two days, you will find another hole, and then you will find that no matter how you patch it, the hole will always appear.

    But unfortunately, you still have to wear it, because you can't find another piece of clothing to wear. ”

    "Teacher, do you mean that we can give up this course altogether, anyway, whether to learn or not, the network is always insecure. Someone bravely stood up and asked.

    "Hehe, this classmate, since we understand the world, we know that one day we will die, so do you think that we are going to die anyway, so it is better to start waiting for nothing now?" No way. Gao Ming smiled slightly.

    " No. The student who got up to ask the question shook his head hurriedly.

    Several students who listened intently couldn't help but chuckle.

    "We all know that we will leave one day, but none of us choose to lie in bed and wait, why, because we all want to roll up our own waves in the long river of time.

    Network security is the same, because of technical limitations, there is no absolute security, and no matter how strict the prevention is, there will be vulnerabilities. But all we have to do is stop the saboteur before he can do it. We don't need to worry about how many vulnerabilities we haven't found yet, we just need to be stronger than the saboteurs. ”

    Surprised, admired, delighted, several emotions appeared on the students' faces, and some began to quickly turn the book, trying to find what Gao Ming said from the book.

    Obviously, there will be no such answer in the book.

    Gao Ming's words just now were a little different from the previous teachers who taught according to the progress of the book, and he was subverting it first.

    However, this kind of knowledge, which is completely detached from the textbook, is more interesting to students who like to accept new things.

    "Anyone can say it with their mouths, but they don't know what the level of their hands is? Li Shengnan naturally wouldn't bow down just because of Gao Ming's words, and muttered in a voice that only Gao Ming could hear on the podium.

    "Hehe, let's do it, let me show you that the so-called network security is not secure. Gao Ming smiled, took out his domestic large-screen mobile phone from his arms, scratched it for a long time, and then clicked a few times.

    Everyone is a little baffled, what do you have to do with network security when you hold your mobile phone and send text messages?

    "Okay, now look at your phones. ”

    Strong curiosity drove everyone to quickly take out their mobile phones from their purses and backpacks, and then there was an uproar.

    It's amazing, some more than they can imagine.
