Chapter 76: Lu Yu Talks About the Firewall!

Li Da indeed let Lu Yu enter the machine room he considered sacred and inviolable, but his heart... was dripping blood.

His pair of eyes almost popped out of their sockets!

Li Da did not intend to let Lu Yu off.

Just now, Wang Meng didn't say that Lu Yu was their group leader, the best at technology among them?

So... as long as I give Lu Yu a tough problem at the exchange meeting, expose his true abilities, wouldn't that work?

Li Da, thinking this way, already had a new idea!

After the students had been in the machine room for a while, Lao Li and President Li Zhengming of Fu Dan Da Xue actually both came.

Accompanying them were several old professors, all specialists in electronic technology, who at Fu Dan Da Xue could be described as towering figures.

The standard of this exchange meeting was higher than anyone could imagine!

Lao Li and Li Zhengming coming was actually expected.

Those several old professors coming was actually Li Zhengming's idea.

Fu Dan Da Xue and Mo Du Electronic Science and Technology University are in a competitive relationship, but...

Li Zhengming knew the topic Professor Chen was researching, and he hoped Fu Dan Da Xue could contribute.

Because... this is a Huaxia topic!

This awareness of the older generation is indeed much stronger than that of many younger people.

At this moment, those several leaders had already sat at the back of the machine room.

Li Da, meanwhile, had come to the front of the machine room.

He will represent Fu Dan Da Xue in explaining their unique understanding of firewall technology.

Students from Mo Du Electronic Science and Technology University may ask questions freely.

If Li Da cannot answer, or if some points are not well explained, the professors behind will supplement.

Then...

The exchange study meeting officially begins!

"I would like to ask Lu Yu, do you know the significance of the existence of a firewall?"

Li Da had not even begun explaining the case when he directly posed a question to Lu Yu, and it was an extremely simple one.

Li Da did it on purpose.

Does a little kid know what a firewall is?

Certainly not!

If Lu Yu can't even answer this most basic question, then doesn't that already explain a lot?

At this moment, Old Li, Li Zhengming, and the others behind couldn't help but frown.

They sensed... Li Da's abnormality.

Lu Yu, however, stood up at this moment, smiling at Li Da, and said: "Li Da, this question you raised is excellent."

Li Da almost spat out a mouthful of old blood!

He was evaluating Lu Yu from a teacher's perspective, but because of that sentence from Lu Yu, Li Da became a student!

Li Da clenched his fists, but he did not erupt; he just stared at Lu Yu, wanting to see what the other could say so he could counterattack.

"Everyone knows we are researching the topic of firewalls."

"But before this, do we really understand what a firewall is?"

"Actually, I have long wanted to share this question with everyone."

"Is the firewall you think of just a wall that blocks others from snooping on your network?"

Lu Yu looked at the people present; he... really now resembled a teacher.

The students from Mo Du Electronic Science and Technology University all lowered their heads.

Although the Fu Dan Da Xue students weren't very clear about what had happened, they also followed suit and lowered their heads.

Lu Yu, however, shook his head at this moment and said: "This is not a true firewall."

"Everyone should take off, viruses are constantly changing, and the means of attacking firewalls are also constantly changing."

"So what a firewall must face is change, not constancy."

"Now, no matter how high-tech the firewall created, it remains unchanged."

"That is to say, the limit of what a firewall can block lies right there."

Having said this, Lu Yu paused for a moment and looked at the audience.

Everyone looked thoughtful, including those several old professors, and even... Li Da standing on the podium.

Lu Yu continued: "Using constancy to face change, the result goes without saying."

"So, I believe a firewall should not merely have the ability to resist external intrusion."

"It also needs learning ability, analytical ability, capable of analyzing virus updates and analyzing changes in attack methods."

Lu Yu spoke for over ten minutes before stopping.

This is his some views on firewalls, of course combined with some knowledge from later eras.

But after he finished speaking, the entire venue fell into silence.

This silence actually lasted two minutes!

The concept Lu Yu proposed can be said to be ahead of its time for this era; they probably had a vague sense of it before, but definitely lacked a clear concept.

So, they were all shocked.

"Um... Lu Yu... old classmate, I want to ask, how can we ensure that the firewall's learning ability can keep up with changes in viruses or attack methods?"

"Suddenly, a voice sounded."

"The voice came from behind the Computer Lab."

"The one asking the question was actually an old professor!"

"This old professor even raised his hand, as if... a student asking a teacher."

"This scene... is actually quite strange."

"But at this moment, no one paid attention to that; all eyes were on Lu Yu, and they all wanted to know the answer."

"Li Da on the podium at this moment... even his breathing became rapid."

"From the moment Lu Yu threw out a new concept, he had already... become completely engrossed, long forgetting that Lu Yu was a child, and even forgetting his own dissatisfaction with Lu Yu."

"Now he, eyes wide open, his face full of yearning for knowledge."

"\"No one can guarantee this. \""

"\"Technology is always progressing. \""

"\"What we need to do is continually improve our own technology. \""

"\"What we need to do is make the firewall's structure more complex, so it can resist or delay virus attacks. \""

"\"Then, we use the time the firewall creates for us to think of new solutions. \""

"\"Isn't this the meaning of the firewall? \""

"Lu Yu's expression also became serious."

"The professor who raised his hand kept his brows furrowed."

"He at this moment had already stood there, falling into contemplation."

"After a while, he then bowed slightly to Lu Yu and said, 'Thank you, thank you, Professor Lu's guidance.'"

"Yes!"

"This old professor actually wanted to call Lu Yu 'Professor Lu' from the start, but because he still retained his rationality at the time, he didn't speak it out."

"Now... the old professor actually still has his rationality."

"But he now completely ignores Lu Yu's age; even in his eyes, Lu Yu is no longer an elementary school student."

"And then..."

"The classroom fell into silence again."

"This time the silence wasn't because Lu Yu spoke, but because... Lu Yu didn't speak."

"The exchange study meeting has only just begun!"

"Lu Yu not speaking, the exchange meeting naturally paused."
