Chapter 283 Professor Qi is my idol!
Her steps were as fast as the wind, leaving only an angry back behind.
Tears glistened in her eyes, and a tear slid down her face as she rushed out of the classroom.
Two students who cared about her said worriedly, "Professor, I'm worried something might have happened to her. Let me go check on her."
"Professor, Yuanyuan just has a childish personality."
Qi Tongwei shook his head and said, "She's already in her early twenties. How can she be a child? She must learn to be responsible for her own actions."
"If she always relies on others' tolerance like this, she will never grow up. If people like you were in the army, I'm afraid the parents of those who were punished wouldn't even recognize you."
"In the military, discipline is ironclad and cannot be slacked off. You must understand that only by strictly demanding of yourselves can you become truly useful."
His tone was firm and unquestionable, like a stern elder teaching a younger generation.
There were ten minutes left before the class ended. Qi Tongwei stood on the podium, his eyes seemingly casually scanning every student in the classroom.
He knew in his heart that with Cui Yuanyuan's ability, it was impossible for her to cause any big stir in such a short time.
However, he was still cautious and continued teaching while quietly checking Cui Yuanyuan's location.
When Qi Tongwei saw that Cui Yuanyuan's location showed that she was always at school, he felt a little relieved.
His little action did not attract anyone's attention. He was like a chess player who controlled the overall situation and planned every move in an orderly manner.
Qi Tongwei's figure on the podium appeared particularly tall and straight, his eyes were deep and sharp, as if he could see through the minds of every student.
His voice is steady and powerful, and every piece of knowledge that comes out of his mouth seems to be endowed with magic. Even those obscure professional knowledge become vivid and interesting under his explanation.
During his lectures, he would also insert some examples from his own practical experience to help students understand those abstract concepts more intuitively.
"Students, cybersecurity is like a war without gunpowder smoke, and the firewall we build is our fortress.
Every line of code is a brick, and the quality and placement of the bricks determine the strength of the fortress.
Just like when I was on a real combat mission, facing the enemy's cyber attack, our firewall was like an indestructible wall, withstanding wave after wave of attacks.
This is why it's so important to build a precise firewall." Qi Tongwei's story made the students feel as if they were in the middle of a fierce cyber battlefield.
"Building a firewall involves many key elements, the first of which is the proper setting of the access control list (ACL).
ACL is like the access control system of a castle. It defines rules to determine which network traffic can enter or leave the network.
For example, we can set rules based on parameters such as source IP address, destination IP address, port number, etc. to prevent unauthorized access.
This requires us to configure each rule precisely to avoid loopholes, otherwise it would be like a malfunction in the castle's access control, allowing the enemy to break in."
"Furthermore, stateful inspection technology is also an important part of firewall construction.
Unlike traditional packet filtering firewalls that only filter based on a single data packet, it tracks the state of the connection.
For example, establishing a TCP connection requires a three-way handshake. The stateful inspection firewall will record the status information of this process, and only data packets that meet the normal connection status will be allowed to pass.
It’s like the guards at a castle not only checking the identity of everyone entering and leaving, but also confirming that their behavior complies with normal procedures.”
“There is also deep packet inspection (DPI) technology, which is a technology that performs in-depth analysis of network data packets.
It can inspect the contents of packets, not just the header information.
For example, it can identify application layer protocols and detect threats such as malware and viruses hidden in data packets.
It’s like setting up a special search team in the castle to carefully check every package entering the castle to prevent any dangerous items from being hidden inside.”
As soon as the get out of class was over, Qi Tongwei was stopped by the dean Ma Wanming with a flattering look on his face.
Ma Wanming's face was filled with a flattering smile, his eyes narrowed into slits, like a cunning fox.
He rubbed his hands and said, "Professor Qi, Xiao Hao is ignorant. Please don't argue with him."
Qi Tongwei snorted coldly, his eyes revealing a cold and disdainful look.
He raised his chin slightly and said, "He's not a three-year-old child anymore. If he can't be responsible for his words and actions, then I don't mind teaching him a lesson."
His voice was not loud, but it was full of majesty, like a gust of cold wind blowing, making Ma Wanming shiver.
Ma Wanming's face changed. He knew in his heart that the power behind Qi Tongwei was not someone he could easily provoke.
His smile instantly became a little stiff, but he still forced himself to say, "It's okay, it's okay. I'll go back and talk to him."
"By the way, Professor Qi, what do you think of my last proposal?" Ma Wanming asked cautiously.
Qi Tongwei suddenly said, "I remember Hao Zhichao was among the participants in the research project you mentioned?"
Ma Wanming looked embarrassed. He scratched his head and said, "Yes, if you mind, I'll tell him..."
Ma Wanming was like an ant on a hot pan at this time. He didn't want to offend either side directly, and beads of sweat had already appeared on his forehead.
Qi Tongwei smiled evilly, and his smile was full of confidence and mystery.
He said, "No, it's more interesting with him."
Ma Wanming was confused. He widened his eyes and looked at Qi Tongwei with a puzzled look.
Qi Tongwei said, "I'll participate."
Then, he left in front of all the students who were watching.
When the students saw this scene, they were all impressed by Qi Tongwei's personal charm.
When dealing with the conflict with Hao Zhichao, he showed an attitude that was magnanimous yet dignified.
He did not take advantage of Hao Zhichao's provocation and was unreasonable, but he would not easily let go of the opportunity to make Hao Zhichao realize his mistakes.
Moreover, when facing Dean Ma Wanming, he did not show any fear or flattery. It was a completely equal dialogue, and he even had a certain degree of initiative.
His wonderful lectures at the podium left a deep impression on the students.
He is not only knowledgeable, but also able to explain the knowledge in a simple and easy-to-understand way.
The practical experience he shared attracted the students like a magnet, making them yearn for the field of network security.
His confidence, wisdom, magnanimity and strong ability have successfully made many students become his fans.
"Wow, Professor Qi is so handsome, he is definitely my idol." A boy said with admiration on his face.
