Chapter 213 Attack is always easier than defense?

Although not every company can achieve the top international level.

But it is expected that in seven or eight years, even with ordinary technology, it will not be a problem to deal with the current rampant mobile phone viruses/viruses.

In the case of having an enterprise-class hard drive from a previous company.

Lin Hui believed that if he rummaged around, he might find something else.

However, this still needs further investigation, and Lin Hui is not absolutely sure yet.

Although he applied for a patent, Lin Hui was not doing it for money this time.

Lin Hui wants to use technology to do positive things.

Since you want to make a contribution, why do you need to create a patent, which is very similar to a technical barrier?

Of course, this is to guard against some unethical companies.

There is no charge for making a patent.

Lin Hui can license the patent to the security department for free without asking for money.

But if it is not made into a patented form:

Do you dare to open source your technology today?

Tomorrow some companies will be able to apply for some similar patents in seconds.

The most disgusting thing is that plagiarists will beat you up.

In turn, it sues you for patent infringement.

Very outrageous.

But this is the reality of the world.

In this Internet environment, being too naive will suffer a big loss.

Lin Hui has always used the worst possible ill will to speculate on his colleagues in China.

After all, Lin Hui is no longer a newbie entering society.

Putting yourself first as a villain and then as a gentleman is not a wrong thing after all.

Specific to the technology against mobile phone viruses/viruses.

Lin Hui rummaged through the enterprise-level hard drive in his previous life for a long time.

After a lot of effort, Lin Hui found some materials related to patents on mobile phone virus/virus prevention.

Uh, mobile phone virus/virus detection method based on base station...

Judging from the data, although this kind of mobile phone virus/virus detection based on 4G base stations has good results.

But this is obviously not suitable for Lin Hui now.

You must know that the current 4G base stations have just started commercial use not long ago.

Many irrelevant people should not know the detailed technical specifications of 4G base stations.

Later generations plant trees, and former generations enjoy the shade

Under such circumstances, what if someone like Lin Hui, who is incompetent with 4G base stations in academia, wants to come up with a device for detecting viruses based on base stations?

In short, virus detection based on base stations is obviously not suitable for Lin Hui.

At least it's not suitable for Lin Hui now.

When it comes to technical handling, the stronger is not the better, the most suitable is the best.

For Lin Hui, there are technologies that are so powerful that they subvert people's current cognition or that have fatal holes in the logical chain.

Moving hastily will only bring endless risks.

Lin Hui didn't want to take some avoidable risks.

Although base station-based virus detection is not very suitable for Lin Hui.

But it wasn't a big problem. Lin Hui quickly found a patent for detecting mobile phone viruses/viruses that was more suitable for him.

Let’s call this patent the SCAN mobile device virus/virus detection patent.

As its name suggests, this patent mainly implements virus/virus detection through scanning.

The principle of this patent is to use specific strings, binary strings or code strings contained in each virus/virus body to detect and scan mobile phone files.

If the detected file matches successfully, it means that the file represents or contains this type of virus/virus.

This detection technology is somewhat similar to molecular probes in biology.

But they are only slightly similar in nature.

The prerequisite for this kind of security measure to play a positive role is to have a strong virus/virus library.

According to this method, it is obvious that the more viruses/viruses there are in the virus/virus library, the more viruses/viruses can be found.

It stands to reason that this kind of technology is not clever, and even a bit stupid.

Compared with some virus dynamic defense technologies or even more advanced artificial intelligence virus dynamic defense.

This kind of technology is completely inadequate.

Even if it is not compared with these advanced anti-virus technologies in the next few years.

Even compared to the technologies used by some current mainstream Internet security companies.

Such technology cannot be called advanced.

Why do you say that?

First of all, the technology of using virus database to detect viruses is a static virus defense technology.

This is destined to be a passive technology to a certain extent.

Secondly, this technology of using virus/virus databases to detect viruses is largely similar to an open-book examination.

Know the "content of the exam in the book" in advance before answering the questions.

If "content outside the book" appears, it will be easy to GG.

This virus detection technology is able to detect known viruses with ease.

But it is easy for unknown viruses/viruses to take hold.

In practical applications, this kind of technology is the norm.

Even in previous lives, such a technology had little use.

After all, viruses cannot always be in the virus reservoir.

Even if there are corresponding security personnel, they will always update the virus/virus types in the technical virus/virus library.

However, the update speed of viruses in the virus database is generally not as fast as the iteration speed of viruses in the external environment.

This is not because security personnel are not trying hard enough.

But because of some obvious reasons:

——It is always easier to attack than to defend.

In the past, after the advent of this technology, the technology of using virus/virus databases for scanning often only served as an afterthought.

Because of this, the people who originally developed this technology did not seem to attach much importance to this technology.

All the technologies related to this previous patent have been simply encapsulated except for the virus/virus library.

The rest of the technology sits on its working hard drive with almost no encryption.

This is undoubtedly cheaper for Lin Hui.

It can be said that it is basically effortless for Lin Hui to reproduce this patent.

Although this technology was useless against mobile phone viruses/viruses of the same period in its previous life.

But this does not hinder the value of this technology to forest ash.

You know, the same method is to use the mobile phone virus/virus database to answer questions.

The question given to Lin Hui was the Internet environment of 2014.

However, Lin Hui was referring to the "examination materials" from 2021.

Although the 21-year-old mobile phone virus/virus library in the previous life still cannot 100% prevent the mobile phone viruses/viruses that have emerged in endlessly in the same period.

However, the types of mobile phone viruses/viruses collected by this mobile phone virus/virus database cover almost all mobile phone viruses/viruses in the previous life before 2021 (containing specific strings, binary strings or code strings).

In this case, the mobile phone virus/virus library naturally covers all mobile phone viruses/viruses that have been released from 2014 to 2021.

In this case, new forms of mobile phone viruses/viruses will continue to emerge even in the Internet environment.

If you want to break through Lin Hui's simple mobile phone virus/virus detection technology, it will take a lot of brain cells.

Unless there are some mobile phone viruses/viruses that have not appeared in previous lives before 2021.

Perhaps we can break through the technology of forest ash transportation.

Putting aside artificially targeted malicious attacks, the technology that Lin Hui is trying to transport is still useful.
