In fact, there are multiple protective measures. For example, in the system, copying of certain confidential files is prohibited. Once you try to copy, the alarm system will be triggered immediately.
In addition, there is permission locking. Without certain permissions, you have no right to access and copy files. The virus is not omnipotent, and it has no thinking. In order to ensure its concealment, it must also act within the permission rules of the entire system.
It is impossible to obtain the highest authority of the system, because almost every birth of the highest authority of these supercomputer systems will require notification of other owners of the same authority, and trigger an alarm system at that time.
The whole process is very complicated.
It can be said that this kind of multiple means of protection makes it almost impossible for current supercomputer systems to be invaded by viruses and steal information, and it is also impossible to control permissions. That is, only ordinary personal computers can be controlled.
Of course, it is another matter for someone to forcibly invade, and it is not the same concept as a virus gaining permissions.
"Yes, so I have already studied this virus. It is a very clever virus. The way it copies data is not to copy the entire document, but to copy part of the text at a time."
"The entire file was copied at least tens of thousands of times, and all the copied data were scrambled and disguised as other files."
"If there is a network, the virus will automatically copy the entire file directly to any new computer that is connected to this computer. As long as it is not found, it will copy itself, including tools such as mobile hard drives, where it will be hidden."
"Under such circumstances, as long as it is not discovered, it will directly and continuously infect and spread. Unless your supercomputer does not have any contact with the outside world, even if you do not use transfer tools such as mobile hard disks, this is simply impossible."
"As long as it is used, it will always have the opportunity to infect confidential computers and steal the files inside." Jiang Yan Hai explained the principle of this virus.
"In other words, you are using a similar virus principle to infect the enemy's supercomputer?" Old Liu They all understood.
"That's right. The requirements for modern files are getting larger and larger. In the past, our files were very small, including viruses, because they were easily detected when the files were large."
"But now, when an ultra-high-definition photo is 20 to 30 MB in size, I believe all professors should know the size of the data copied on a large scale. Many units use G to describe it. It is too simple to hide some pure text information."
Jiang Yan Hai said seriously.
"I think you can give it a try." Old Liu thought for a while and then said.
"What do you think?"
"I don't have any objection, but we can't decide on this thing, and if we want this computer virus to steal our files and send them back, we can bring your virus back with us."
"We also need to carefully consider how to design these stolen documents."
"Well, Xiao Jiang, you go back first. We may have to discuss it before we can decide, and it's not our decision." Old Liu said simply.
"Yes!" Jiang Yan Hai didn't waste any words and agreed directly.
After finalizing the matter here, Jiang Yan Hai no longer needs to stay here. He can leave directly. As for his fighter jet, it has been prepared for him. A J10C, the latest improved model, is a little more advanced than the one he flew before taking over J10S Azure Dragon.
That one seemed to be a J10B.
But no matter what, when you drive your beloved small phone, although it is no longer your last small phone, it is still your own small phone. Whether you can drive the J20 next depends on whether you work hard enough.
So Jiang Yan Hai, who came back, was immediately assigned a flight mission, but what he didn't expect was that the new fighter jet he flew back was re-sprayed with stars, but instead of three stars, it became four stars!
"You kid... if you find another chance, maybe you will be the first Ace Pilot after we enter the new century!" Zhang Mingwu looked at the stars on the Jiang Yan Hai fighter with some envy.
He was one of the earlier pilots, but all he got in the end was just a star on his fighter jet.
And now this young man has four!
There is only the last one left before the internationally recognized five-star Ace Pilot!
Although sometimes you may not be able to get this one in your life, but if you don't say anything else, even with these four stars, you are considered awesome.
"Okay, your fighter jets have been arranged, and then you can go on the mission tomorrow." Zhang Mingwu took out a mission report directly from his drawer and threw it to Jiang Yan Hai.
Jiang Yan Hai took a look at the report and was immediately dumbfounded.
"Didn't you ask me to carry out the mission? Why did I go to the northeast?" Jiang Yan Hai was a little confused. Commander, we have something to say. You were performing the mission, why did you go to the northeast all at once?
"Yes, I just want you to perform a mission and fly to the northeast for half a month." Zhang Mingwu said matter-of-factly.
Jiang Yan Hai: "..."
"What are you doing? You don't know what you did? Just keep a low profile here at this time." Zhang Mingwu said with a smile.
Jiang Yan Hai is even more speechless. You asked me to keep a low profile. Why are you giving me four stars? Why keep a low profile when you have that thing?
"Okay, let's go." Zhang Mingwu smiled.
Jiang Yan Hai What else can I say? Just go ahead and pack your equipment. I didn't have time to say hello to Wu Di. They are still patrolling.
"Eagle's Nest, Eagle's Nest, the Falcon is requesting to take off." Jiang Yan Hai glanced at the girl in the white T-shirt. After boarding the plane, he placed the photo directly outside, so it was naturally visible at this moment.
"The Falcon can take off. After taking off, it will extend the border all the way north to complete the border patrol mission, then arrive near the target to complete an aerial refueling, and then land at Air Force Base, which belongs to the northern theater." Eagle's Nest responded directly.
"Falcon understands!" Jiang Yan Hai responded, decisively and skillfully adding oil and pulling the lever to take off.
