Chapter 246

.

In Jingya Court, Shi Lei deleted a small part of the source code for the virus-free antivirus firewall. He had a new idea in his mind.

There were indeed thousands of types of computer viruses. It could even be said that they were endless. To make an anti-virus software include all the virus characteristics, even if it was really possible to do it. But there were always new types of computer viruses. There would always be viruses that the anti-virus software could not identify!

Shi Lei had been thinking of a dead end. He wanted to defend himself against all the viruses without configuring a virus signature library. An anti-virus firewall that could achieve this effect could only be a real AI program.

For now, an AI program was just a beautiful lie!

That was to say, an anti-virus software that did not configure a virus signature library but could accurately identify all the viruses and automatically defend against them did not exist!

Although such anti-virus software did not exist, it did not mean that it could not achieve such an effect. It was like going to Rome. One did not have to take a plane. One could use other means of transportation to achieve his goal.

The moment Shi Lei deleted the source code for the anti-virus firewall, he thought of a brain-teaser.

The brain-teaser about storing the sea in a calabash. Ask how to store the sea in a calabash. The answer was to store the sea outside the calabash!

From this sudden twist in his brain, Shi Lei suddenly had a flash of inspiration.

Why did he have to identify viruses?

There were too many types of computer viruses. Even if he had a large number of virus signature libraries, he could not say that he could identify all the viruses. But there was no rule that he had to identify all the viruses!

It was like storing the sea outside the calabash. If he could not identify all the viruses, he might as well not identify the viruses. Instead, he would identify the files that needed to be protected!

The files in a computer system were fixed. They were not like viruses, which could change endlessly.

An anti-virus firewall software could be designed to directly protect the files in the computer system and the files that needed to be protected. It could ignore viruses and illegal malicious data packets.

Any computer viruses or illegal data packets, once they attempted to modify the protected files, they would be directly deleted!

There was no need to identify the unknown files to see if they were viruses or other unknown data packets. As long as they were malicious, they would be deleted immediately.

For example, the system of server No. 6 was based on the Linux system by Shi Lei. He had modified the kernel of the system. This Linux system's system files were fixed files. It was not like a computer virus that kept changing from time to time.

Shi Lei only needed to design a software to protect all the files in the system. He also needed to add the other files in server number one to the protection sequence.

Once a virus or illegal data packet invaded Server No.6 while Shi Lei was not paying attention and tried to modify the system settings, the system would change the configuration file, which would cause changes to the protected files. Then, the protection program would be triggered, and the file that attempted to modify the system settings would be deleted.

No matter what kind of virus that file was, or whether it was a garbage file released by an illegal data package, the anti-virus software did not need to know. The antivirus software only needed to know that the system it protected would not be compromised.

Once there was any file that attempted to infringe on the system's files or protected files, the anti-virus software would immediately stop its memory process and delete it!

Designing an anti-virus software in this way had already achieved Shi Lei's original intention. It didn't have any virus storage, but it could kill any virus!

In his mind, he thought about it carefully. Shi Lei could definitely make such a protection program!

After figuring out the anti-virus firewall model, Shi Lei immediately started coding in the programming software. His ten fingers danced on the keyboard like a beautiful butterfly.

In the online world, in the voice communication channel of the core of the Hacker Alliance, Black Heart, who was at the bottom of the core, shouted, "Black Devil, Black Devil, have you two researched anything? Can the Moon Virus be cracked? "

How could the Moon Virus outbreak in Voisin be hidden from Mr. Xia's Hacker Alliance?

As the representative of Mr. Xia's hacker community, the Hacker Alliance was responsible for monitoring Voisin's hacker community. One of the daily tasks of the Hacker Alliance was to observe the Voisin network at any time.

When Black Devil and Black Devil were browsing the Voisin network, they discovered that there was an extremely powerful virus outbreak in their network. It was even more troublesome than Mr. Xia's Sakura Virus outbreak!

"Black Heart, don't worry, don't worry. We are still researching it. The structure of the Moon Virus is very simple. It just controls the computer to perform low-level formatting. However, the transmission mode and packaging process are very advanced. We can't open it for the time being. "Black Devil's catchphrase was" don't worry. "

Black Heart snorted. "I'm not worried! Boss Black Saber is worried! Boss Black Saber is worried that the Moon Virus will spread into Mr. Xia's territory. I really don't know what Boss Black Saber is thinking. These things should be the CNS and the four major Internet security bureaus. What is Boss Black Saber worried about? "

Black Devil's muffled voice was heard. It was unknown if his voice had been modified by an electronic voice changer. His tone sounded very strange, as if something was strangling his neck.

"You don't have to worry about that. We found the existence of IP restrictions in the Moon Virus. As long as Mr. Xia's people don't jump to Voisin's IP browsing, they won't be infected by the Moon Virus! "

Black Heart asked curiously, "Black Devil, Black Devil, do you think this Moon Virus was created by Mr. M? Although Mr. M made a statement on NHK's official website, after the outbreak of the Moon Virus, Mr. M mysteriously disappeared without any news! "

"Black Heart, don't worry. We will know when the time comes. If it is really Mr. M, I think Mr. M will stand up and admit it. If it is not Mr. M, Voisin's Ministry of Foreign Affairs International Intelligence Service will also stand up and make an announcement. "Black Devil laughed twice and said.

"Hmph! Black Devil, can you stop talking and don't worry? " Black Heart was a little annoyed. "Black Devil, Voisin is in big trouble this time. Why don't we, the Hacker Alliance, launch another attack on them? It's already the end of the year. Give them New Year's gifts in advance! "

Black Devil said in a muffled voice, "You ask Boss Black Saber! Black Devil, let's go to the encrypted channel. Black Heart is so noisy! "

Sure enough, Black Ghost and Black Demon established an encrypted channel to reject Blackheart, making Blackheart groan.

"Hmph! You two virus maniacs! I'll contact Second Brother and instigate him so that Second Brother can organize the third invasion of the Walsang Kingdom this year! " Black Heart whispered to himself. The Second Brother he mentioned was the second-in-command of the Hacker Alliance, Black Tiger.

Black Tiger was impulsive, and his technology was inclined to attack and invade. He was very interested in invading Voisin.

With the outbreak of the Moon Virus, the Hacker Alliance might target Voisin and launch the third cyber war in 7551!

Jingya Court. Shi Lei was completely immersed in writing a new anti-virus firewall.

According to the theory of reverse thinking, Shi Lei made the entire anti-virus firewall from nothing to some outline, and then gradually full of feathers.

After four o 'clock in the morning, Shi Lei stretched his back. His spine and waist made a sound of joints. Looking at the program that was being debugged line by line, Shi Lei's eyes showed a satisfied look.

After more than eight hours of continuous struggle, Shi Lei finally wrote the anti-virus firewall in his heart.

Looking at the console debugging line by line and passing one by one, the smile on Shi Lei's face became more and more obvious. After more than an hour, all the code of the anti-virus firewall was finally debugged.

There were some small mistakes, and in the process of line debugging, Shi Lei corrected them one by one. After confirming that there were no errors, Shi Lei clicked to run the newly written anti-virus firewall.

The anti-virus firewall ran smoothly. After only a few minutes, Shi Lei closed the anti-virus firewall and began to seal and encrypt the anti-virus firewall.

The encryption process used the behavior dynamic capture program to make the encryption of the entire program impeccable.

After the sealing was completed, it was copied out through the USB drive and installed on the laptop. This laptop was Shi Lei's old laptop before school started.

The laptop brought back from Voisin, because it was installed with the FCH system, was sold to the Shuangqing Bureau together with the Steel Hao.

After installing the newly written anti-virus firewall on his old laptop, Shi Lei first started to set up the protection list, the access rules allowed by the firewall, and the packet filtering rules.

After setting up, Shi Lei started the anti-virus firewall and then used Server No.6 to hack into his old laptop.

The performance of Server No.6 was only a little better than a high-end personal computer, about ten times that of the old laptop. With Shi Lei's skills, it was almost easy to hack into the old laptop through Server No.6.

However, this time, Shi Lei ran into trouble!

The mail bombs and Trojan viruses sent through Server No.6 were directly deleted by the fireproof software. It was impossible for them to enter the old laptop.

Although the old laptop's system resources were almost all occupied by the anti-virus firewall when Shi Lei attacked, it still resisted tenaciously.

Seeing that the viruses and Trojan viruses and mail bombs could not enter, Shi Lei changed his method. He chose a loophole in the laptop's system and tried to enter from the outside through the loophole in the laptop's system.

However, when Shi Lei invaded the loophole, he was directly blocked by the anti-virus firewall. Non-permitted normal access could not pass through the restrictions of the anti-virus firewall and was rejected.

Shi Lei was surprised. He attacked the loophole in the system, but the anti-virus firewall could actually defend against it!

After more than half an hour of continuous testing, the performance of Server No.6 was ten times better than the old laptop's. In addition, Shi Lei was the world's top hacker, but he could not break through the anti-virus firewall.

Shi Lei was not angry. Instead, he laughed happily!

The anti-virus firewall of the virus-free database was a success!

The excited Shi Lei tried again. He disguised it as a normal access and entered the old laptop's system through port 35.

The disguised normal access successfully deceived the anti-virus firewall, but Shi Lei could not do anything. Otherwise, the anti-virus firewall would be triggered and it would automatically defend itself.

Shi Lei did not trigger any other settings. Instead, he attacked the anti-virus firewall itself on a whim …
