Defect another world

Chapter 231 Who Buried the Loophole?
"Well, I did write these codes."

Meng Fei tapped the keyboard, and the codes were directly displayed on the screen.

"Every line of code is written by me, in my style."

At that time, his predecessor, Meng Fei, had just graduated, and he had no memory of his predecessor, Meng Fei.

But he read a lot of code written by his predecessor Meng Fei.You can see many habits that are inherited in one continuous line.

"But in fact, Ouyang Cong asked me to write these codes."

This is an inference of Meng Fei.

At that time, his predecessor had just graduated. As a novice, he joined the project of developing a security system for the Bureau of Secrets, and it was absolutely impossible for him to make such a major design on his own.

There is only one possibility, that is, the boss put forward the requirements, and then he did detailed design and coding.Meng Fei's boss has always been Ouyang Cong.

"But Ouyang Cong has been missing for a long time."

Roan spread his hands obviously pretending.

"Are you trying to push things on someone you can't find?"

"No no no."

Meng Fei shook his head.

"So I looked through all the historical emails and chat records between me and Ouyang Cong, trying to find out what he told me to develop this set of debugging information."

"Have you found it?"

Roan asked very calmly.

"No. But isn't that weird?

"I thought about it later, and I don't think it's surprising.

"Saving decrypted data in debug logs is actually a security hole.

"Because the encryption strength of the debug log is much weaker than the encryption strength of the encryption system. This is equivalent to reducing the encryption strength of the data.

"I had just graduated at the time, and I had no experience in these things, so I might not necessarily challenge this kind of design.

"But Ouyang Cong is a very cautious person, if he receives such a request, what will he do?
"Since it is his boss who made the request, he will definitely not refuse. But if this incident really leads to data leakage in the future, wouldn't he be held responsible?"

"So he's definitely going to try to get away with it.

"First, he will verbally explain the demand, and will not use software chat or email to send the demand to me. This will not leave any evidence against him.

"Second, what if he is involved in my accident? He will definitely leave evidence of your communication with him. "

In front of everyone, Meng Fei logged into Mantis's office system, and then selected Ouyang Cong's intranet chat records.

Roan's eyes changed slightly.

"How can you log in to Ouyang Cong's intranet office account?"

"It's very simple, I cracked it."

This is the same as asking "Why do you have someone else's house key" and the person responding "It's simple I stole one".

Everyone fell into silence, no one challenged, no one questioned.Because it doesn't matter at all.

"Then go back to five years ago, June 8015, 6..."

"You turned over so many chat records."

Roan sneered.

Meng Fei turned the mouse wheel to flip through the chat records, and replied:

"Not only chat records, but also emails. I think if Ouyang Cong wants to be safer, he should send an email to confirm the request.

"But I went through all his emails and couldn't find anything.

"It's also possible that there was an email, but you deleted it.

"It's here. This is the message Ouyang Cong sent you at eleven o'clock that night. Look at the content——

"'Boss, if the debugging information of the decryption system is designed according to your idea, there will be too much information saved.

"'What if it leads to a data breach in the future?'"

"Then your answer is:

"'It is better to have more detailed debugging information in the development stage. Just turn off all these debugging information when it is officially released.'

"Ouyang Cong replied 'OK'."

Meng Fei felt that his throat was a bit dry, and after drinking a small sip of water, he immediately recovered his clear voice.

"Ouyang Cong is indeed a very smart person. He is not really asking for instructions when he asks you like this.

"He did this only to leave a record. In the future, if the data is leaked and the designer is held accountable, he will not have to bear it alone.

"Because your answer has proved that you are the one who made the design, not Ouyang Cong!
"As for me, I am a person who writes code. I will write whatever code the boss asks me to write.

"I'm just your tool man, you are the mastermind behind the scenes!"

Roan's complexion was not very good.He thought he was very thorough in his work, but he never expected to meet a more watertight Ouyang Cong.This is his mistake.

There have been some subtle changes in the atmosphere of the situation, and Antu and the others looked more and more solemnly, focusing more on Luo An.

In fact, they were also more nervous.Because if it was Luo An to deal with, it would be much more difficult than dealing with Meng Fei.

No one knows how much this Xuannv's disciple, a young genius of origin studies, really has.

"Relying on a chat history from five years ago, you have indeed managed to get rid of the suspicion of writing code.

"But this record does not mean that I am suspected of deliberately burying a back door to steal negative entropy. This is at best a design error."

Luo An leaned back, crossed his legs, and said An Ran.

"It's you, how do you explain the negative entropy you found in the Secret Bureau and then lost?

"According to what you said, the recovered negative entropy can be kept in the underground computer room of the Secret Bureau.

"I've never been in that place before. Don't you want to push it on my head?

"Or do you want to admit that when you designed to catch the demon spirits, you really got it wrong?

"It was you who put the real negative entropy data into the car, and was stolen by the gluttonous people in the end, and the garbage data was left in the computer room?"

Meng Fei did not answer his question directly, but shifted the topic to the national air computer.

"I checked the history of access to the national air computer.

"I found out that since the National Air Computer was built, the only time you have access is from around 05:30 pm to [-]:[-] pm today.

"Isn't that kind of weird?

"Later, I checked some information and found out that this is stipulated in the "National Air Force Algorithm".

"Anyone who has participated in the design and construction of the national air computer is normally prohibited from accessing the national air computer.

"In this way, even if you designers and builders leave a back door that only you know about during the design or construction process, it is useless.

"Because you don't allow access to the air computer at all, and you can't use it with a back door.

"Not only you, but also your teacher, Xuannv, is also on the blacklist. Because the computer was built by the Origin Society."

"But you got access this afternoon.

"Because you captured the demon spirit in the battle of the dense forest reservoir. Not everyone can touch such a dangerous thing.

"The devil needs to do a consciousness test, which can only be operated by you, so you must access the national air computer."

"So what if I plug into the National Air Computer?"

Roan still had an indifferent attitude.

Meng Fei gritted his teeth a bit.

Although he admires Luo An very much, he can't bear to get angry when he thinks that the negative entropy recovered after working hard for several days and nights has been wiped into garbage data!
