This paper first expounds the overview of computer security technology, then analyzes the security application of computers in e-commerce, summarizes the importance of computer security to computer development, and finally puts forward the countermeasures of computer security for readers' reference.

1. Privacy security of computer users

Everyone has their own privacy, mostly involving aspects that people don't want people to know. Due to the popularity of new shopping methods such as online shopping at this stage, it has brought a lot of convenience to people's lives. People can often sit at home and browse the goods all over the country and buy them calmly. Because of the low operating cost of online stores, customers can often enjoy high quality and low price services. But everyone fills in personal data when shopping online, even including password accounts that third-party software needs to fill in. Is this safe? These problems are also increasingly prominent. Recently, the relevant media reported many security problems in the online shopping process, such as the personal information of users being attacked by hacker software, which led to the disclosure of personal information such as user account passwords and damage to people's personal property.

Online shopping is a kind of C2C e-commerce. Now it seems to be a good supplement to the current consumption pattern, but as long as the security problem is not solved, it will be a constraint that puzzles its development.

2. Virus

Not only China, but also all countries with rapid development of computer technology will encounter this problem. First of all, we mentioned the virus in the online shopping we discussed before. Many websites now have Trojans. At the same time, when we download what we want from the Internet, it is often mixed with virus programs. Even a newly installed computer is likely to be caught in a Trojan horse by some people with ulterior motives in the installed hard disk. These Trojan horses can be said to be pervasive and hard to prevent. Among them, there are many network viruses that have caused an uproar in recent years. Of course, these viruses are not limited to Trojan horse viruses. For example, the panda burning incense is a variant worm virus, and there is the famous Trojan virus, which can sneak into your computer disguised as a utility or other programs, and then there will be endless troubles. As you can imagine, your computer portal is wide open, and all your information is clearly peeped.

3. Hacking

Network hackers are also a big challenge to computer security. Many people think that cyber hackers are mostly experts in network decision-making, not to mention few, and they are definitely not aimed at ordinary people, so these cyber hackers will never attack their personal computers at leisure. Actually, it is not. Just search on major search engines and you will find many kinds of hacker software. For example, there are more than a dozen hacking softwares in China, such as chasing snow, tamping knives and glaciers. These hacker softwares range from password decoding to tampering. As for the method of use, you can find detailed instructions, and most of them are not troublesome. If these methods are used to deal with the national system, of course, it will not work, but if they are only used to deal with the personal computers of ordinary users, it will be more than enough. Of course, in recent years, the college entrance examination marking system has also been attacked by hackers and the company system has been paralyzed. The former uses hacker software, and the latter uses information bombs to send a lot of junk information, which leads to the paralysis of the other company's network system and causes a lot of economic losses. On the one hand, these cases show that computer security is in jeopardy under the attack of hackers, on the other hand, it also shows that the Ministry of Telecommunications does not pay enough attention to network security.

At present, we have encountered so many computer security problems, and we have many ways to solve these problems. Although I dare not say that all the disadvantages will be swept away in an instant, I believe that one day our network will be more secure. So what measures should be taken to curb these problems? In my humble opinion, we should pay more attention to the following points:

1. Cybercrime should be cracked down in legislation: in this respect, China obviously lags behind developed countries, and the number of netizens in China has now exceeded 600 million. But these 600 million people have no special laws to protect their network security, including the security of a large number of personal information in their networks. In troubled times, the application of codes is emphasized, and the online world in China today is really troubled times. A large number of people with ulterior motives wantonly create and spread false information, and even openly insult and insult others. They are so arrogant because our rule of law is not perfect. The principle that there are laws to follow, laws to be followed and law enforcement to be strict advocated by our country is lacking in network management, which also encourages the arrogance of cyber criminals. The sentencing method of cyber hackers is also vague, and there is no special law to investigate it, so there are only a few cyber hackers who make trouble, but it is these people who are really shocking! Therefore, we call on the state to introduce targeted legal provisions as soon as possible to limit network security issues.

2. The Ministry of Industry and Information Technology should pay more attention to everyone's network security: in fact, many hacker attacks can be avoided. Although some hackers have high-end technology, the Ministry of Industry and Information Technology, a lower-level hacker, can still avoid it through its own attention. As long as the Ministry of Industry and Information Technology adds a security system to our computer link, many hacker attacks can be filtered out. Because most computers in our country are hung in the Ministry of Industry and Information Technology, whether it's computers used by hackers or our personal computers, as long as our network links are secure enough and a large number of low-end hackers can't touch our computers at all, these problems can naturally be avoided. What is more gratifying to everyone is that after experiencing early unfamiliarity, the Ministry of Industry and Information Technology has begun to pay attention to the network security of the majority of netizens. Therefore, we can see that the Ministry of Industry and Information Technology has increased its investment in network security in recent years, and the development of network link protection programs has also increased, which shows us the hope and determination to put an end to hackers.

3. The development of network security software should be more targeted: Now many people say that our network security has so many problems and that I am sensational, because they say that they have various firewalls, so their computers are very safe. Most computers in China must be more or less, or there were all kinds of Trojan viruses in the past or now. Then why can't you stop pervasive viruses and invading hackers when you have a firewall installed? The makers of these firewalls will tell you that the virus has mutated. We have a powerful virus database, but we can't let it constantly mutate. Can you try to estimate the evolutionary possibility of the virus, try to plan ahead if possible, think about the possible evolutionary direction of the virus in advance, and defend it in advance? But I think this is a wise game between security software designers and hacker viruses, but how many hackers can there be, and how many designers and practitioners of our network security software? I believe that as long as we work together, then I believe we will definitely create a safer firewall, a firewall without a short board. I believe this day is just around the corner.

4. Netizens should strengthen their awareness of network security: Even if our telecom departments try harder, the legislation is stricter and the firewall is safer, if we don't strengthen our awareness of network security, everything will be empty talk. First of all, we should always pay special attention to the security of our personal information, and we must never leave our personal information casually. Secondly, when browsing the web, we should not browse pornographic and other bad websites, because these websites are often virus libraries, and if you enter, you will increase your sense of insecurity. Moreover, don't think that the firewall is not omnipotent, its imperfection is relative. At least for most known viruses, our current firewall can still effectively intercept them. Finally, try to use genuine software. Genuine software will never be infected with viruses. If you have to download software from the Internet, try to download it from a big and guaranteed website, and remember not to advertise at will. If the firewall prompts a malicious virus during downloading, it should immediately stop downloading and kill it.

Computer security has become an important part of the development of computer technology. Although we are facing such and such problems at present, I imagine that if we unite in all aspects and give 600 million netizens a safe and healthy computer environment, we will definitely overcome these problems.
