Chapter 280 Do It Yourself
As for firewalls and anti-virus software, the most essential difference between the two is that the main function of anti-virus software is to prevent viruses; while firewall software is used to defend against hacker attacks.

The positioning of anti-virus software and firewall software is different. After installing anti-virus software, it cannot prevent hackers from attacking, so it is necessary to install firewall software to protect system security.

At the same time, the firewall does not deal with viruses, so you need to install anti-virus software.

A firewall is software located between a computer and the network to which it is connected. All network communications flowing in and out of a computer with a firewall installed must pass through the firewall.

Using a firewall is also the first step to ensure network security. It is essential to have a firewall, and a firewall is also an indispensable barrier to protect information security.

Now that you can do it yourself, why do you pretend to be someone else; and the firewalls on the market now have various bugs.

For hackers, it is the same as not installing.

Sun Chao remembered something while debugging.

By the way, your own supercomputer should be almost there.

When Sun Chao decided to participate in this competition, he asked Ren Haijun to prepare a supercomputer for himself. In fact, Sun Chao planned to directly hack a supercomputer for his own use at the beginning, but Sun Chao felt that it would be safest to buy one by himself, after all This is my first springboard.

In addition, Sun Chao was afraid that his skills would not work.

If you want to ask Sun Chao what he bought the supercomputer for, of course it is used as a server.

After Sun Chao got it right, the war of words between Wang Bin and Fan Kexin was over, and in the end Wang Bin was defeated.

In the past few days, Sun Chao has skipped all the classes except the compulsory ones.

This made Sun Chao's classmates very curious.

Sun Chao planned to skip all the other classes after finishing the compulsory class today; today he can finish the rest.

Sun Chao rode his bicycle directly to the opposite dormitory of his classmates.

Wang Qing sharp-eyed saw Sun Chao riding his bicycle towards the dormitory.

Wang Qing is the girl who wanted to chase after Sun Chao when she saw Sun Chao at the beginning of school.

Although this thought has been dismissed now, as long as she can see Sun Chao, Wang Qing's eyes cannot be separated from Sun Chao, and her eyes often drift to Sun Chao's face.

So as soon as Sun Chao left the team, Wang Qing discovered it immediately.

Once outside the classroom, everyone went to the classroom for the next class together.

Wang Qing and her roommates also walked to the classroom together.

The topic of conversation among the girls on the road was also Sun Chao.

Wang Qing said to her companion, "Have you seen it? Chaoshen skipped class again."

After all, a person who never skipped class, now skipped class, which made everyone very curious.

"Do you think the school girl is in love?" the girl next to her asked, blinking her big Kazilan eyes.

Wang Qing was the first to object: "Impossible, if the school girl fell in love, the campus network would have exploded."

"Yes." The girl nodded in agreement.

"When I go back at night, I also check the campus website to see if there are any new photos of the school grass."

"I'll take a look too. Do you know that girls who never used to go to the campus network now go around when they have something to do?"

Here, the other boys in the class also got together and started gossiping.

"What do you think Chaoshen is busy with these days? People who never skip classes even skipped classes for several days in a row."

"I think Sun Chao may be busy making up computer science courses recently. It's normal for him to be busy for a few months to complete the one-year course."

"I think this is the most likely possibility. No matter how awesome the super god is, no matter how good the memory is, it doesn't mean that you have to read all the knowledge in the book. It doesn't take time."

Some people are also curious whether Sun Chao will break the record of being the first in computer science.

He asked: "You said, Chaoshen has just transferred to the computer for a few days, and the quarterly exam will start on the first of next month. Do you think Chaoshen will fall from the first place in the grade? "

The two classmates next to him looked at this person like a fool, "Don't you know the speed of Chaoshen's reading? You fell down, you are thinking too much."

This man has obsessive confidence in Sun Chao.

If Sun Chao heard it, he would say: Brother, you have too much confidence in me, I don't even have it myself.

The male student who spoke just now really doesn't know, he doesn't have enough time to study every day, so how can he have time to chat.

Confused and asked: "What does it mean that Super God reads quickly?"

"I really don't know? Your news is too closed." The boy next to him said something directly.

While they were there, they told the science popularizer: "Even if you don't know how fast Super God can read books, you do know Sun Chao's memory, right?"

The boy nodded in agreement. There are still a few people who don't know about this.

"We have pre-exam review for each exam. Do you think Sun Chao's memory can be lost? I think you are thinking too much."

"Then what do you mean by reading fast?"

The boy still wanted to understand what they were talking about.

"Before, Shen Yue said that he went to Sun Chao's dormitory and saw that Sun Chao's reading speed was very fast."

The classmate next to him added: "Sun Chao's roommate said that Sun Chao can turn a page in a few seconds or ten seconds, and can memorize a book two or three times; that is really terrifying."

"I guess Chaoshen doesn't go to the library to read because he is afraid of hurting everyone."

There are also those who disagree: "I think Sun Chao is afraid of being regarded as flipping through books."

"What you said is not right." A classmate who saw the grand occasion in the library said.

Several people looked at this classmate together, "I saw that when Chaoshen was reading in the library, the girls next to him were not in the mood to read; I think this is the reason why Chaoshen didn't go to the library to read, who would like to read books by themselves? Someone is watching me all the time while reading; if it were me, I would definitely feel uncomfortable all over."

"..."

Today Sun Chao finally completed the firewall he was satisfied with.

Sun Chao named his firewall, Mount Tai.

When Sun Chao returned to the dormitory, there was no one in the dormitory who happened to facilitate his operations.

Sun Chao turned on the laptop and desktop computer together.

Sun Chao plans to try the effect of Taishan Firewall.

Sun Chao first used the scanner in his laptop to scan the campus network inside the school.

Sun Chao tried it before, but the tool was not convenient, so Sun Chao gave up directly.

After all, when he first entered school, Sun Chao knew very little computer knowledge, and this was a top university, so there were quite a few computer professionals.

Now Sun Chao wanted to try it out, and taking down the campus network shouldn't be a problem.

Sun Chao intends to use the server of the campus network as his own broiler. The server of Sun Chao's school is very good.

Even if you spend money to buy servers on the surface, you can only buy this level.

Soon the scanner came out with results, and Sun Chao's screen showed more than a dozen loopholes. Sun Chao knew that some of these were honeypots, which were left on purpose by the managers. After screening, Sun Chao still found two real loopholes.

Sun Chao hacked directly, planning to get an administrator account for himself.
