Computers and the Internet have gradually become part of the social development of our country. The emergence of the computer network has greatly changed people's way of life and work. The whole society has entered a completely new stage of development. However, with the in-depth development of computer network technology, there are many problems in the use of the process, security technology has become an important factor affecting the development of the computer, a variety of problems restricting the development of the computer system. Therefore, in order to ensure the stable operation of the computer, the relevant personnel must solve these problems, strengthen the development of computer software, only in this way can improve the security of the computer operation.

Computer security technology refers to the protection of various software systems, including the protection of the system internal data, system software, system hardware. The biggest advantage of security technology is that it can effectively prevent the computer system from malicious attack or virus invasion, can resist the attack behavior to a certain extent, so as to ensure the security of the computer internal software, ensure the normal operation of the computer system. In addition, reasonable use of security technology can ensure the security of users' privacy information, prevent hackers from intruding, and ensure the normal use of computer software.

Under normal circumstances, if the computer itself a variety of basic equipment, network communication equipment and other physical facilities damaged, it will directly affect the security of the computer system. There are many reasons for physical equipment damage, such as circuit aging, natural disasters, man-made damage, etc., these will lead to the computer can not run normally, serious will also lead to network equipment damage, computer system crash, etc., so as to allow users to cause a large loss. The reasons for the damage of physical equipment are complex, which increases the difficulty of using security technology invisibly. Because these are uncontrollable factors, it will directly affect the development of computer software once it happens. Therefore, regular maintenance, maintenance, clean computer equipment is very important, but also check whether the circuit is complete, operation is reasonable, only in this way can ensure the stable operation of the computer, so as to improve the security of the computer.

Hacker attack refers to the use of their own computer knowledge, in view of the existing problems of the computer system, through technical tools to attack the computer, resulting in computer system paralysis, which has a great impact on software development work. Nowadays, there are many cases of hacker attacks on the Internet. Only by improving vigilance and taking measures can we reduce unnecessary losses. Once attacked by hackers, it will not only damage the computer system and equipment, but also cause the leakage of user information, posing a serious threat to user privacy. Computer virus attack is very powerful, and the spread of the virus quickly, once infected, quickly into the various components of a computer system, the damage caused by not forecast, especially in the process of software development, it will not only reduce the speed of the computer, and can damage the important document, the destruction of computer hardware.

Hardware and software are important components of computer system, but in the current computer software market, some irregular and pirated software has occupied most of the market proportion, which leads to some legitimate software into a sales bottleneck period, and the security of computer system cannot be guaranteed. In addition, there is no timely update of all kinds of computer software, hardware and other accessories, can not detect the vulnerability of the system in time, thereby reducing the security of the computer system.

At present, People's Daily life, work more and more inseparable from the help of computers, computers are widely used in all walks of life; However, due to the weak knowledge of many computer users, there are a lot of improper behaviors in the operation. For example, users continue to use the computer even if there are problems with the computer, which causes harm to the computer system. In addition, most computer users network security awareness is not in place, do not understand the various configurations of the computer, such as the use of unreasonable firewall, computer protection is not standard, these will affect the system security.

Nowadays, all kinds of computer security technology emerge in the market, the overall application effect is also very ideal, firewall technology is no exception. The technology can protect computer systems by keeping all kinds of unsafe information out of the safe range, but some audited applications can enter. The technology also has the function of dividing internal network to some extent, which can protect important network segments through isolation, thus improving security. Vulnerability scanning technology refers to the detection and repair of vulnerability before the computer system is attacked. It can ensure the security of the computer system to a large extent by scanning the computer system to analyze the security index of the network system. Information encryption technology can rearrange all kinds of information to hide the real information, so as to improve the security of information system and reduce the information loss of users.

In recent years, China has developed a new intrusion detection technology, and the overall use effect is very obvious. This technology can quickly analyze the computer system, network system, once found abnormal behavior in the system, will automatically sound the alarm, so as to ensure the stable operation of the computer. Intrusion detection technology is a combination of reasoning technology, communication technology and statistical technology. It also involves artificial intelligence, which can monitor computer systems in real time and intelligently identify abnormal behaviors, thus ensuring user information security. There are many types of intrusion detection technologies, which are mainly divided into different monitoring objects. For example, network intrusion detection technology mainly guarantees the security of the whole network. Intrusion detection technology mainly guarantees host security; Hybrid intrusion detection technology combines the advantages of the above mentioned two, and the protection range is broader and the application effect is more obvious.

Anti-computer virus technology can be used to eliminate the virus that spreads fast and destroys strongly. Inspection, prevention, elimination is an important entry point of the technology, can achieve the goal of ensuring the security of the computer system, among which: prevention of viruses refers to the installation of relevant anti-virus programs in the computer, so as to reduce the probability of virus intrusion into the system, the actual operation will also take information encryption or system monitoring and other measures. In anti-virus technology, there are two ways to check the virus. The second is to compare the operation data of a certain period of time, so as to get the results. No matter what method is used, as long as the virus is determined to invade the computer system, the relevant personnel should take immediate measures to solve the problem. It should be noted that although the installation of anti-virus software is one of the most frequently used methods, but because of the virus update rate is very fast, if you cannot update the software in time, then it will not be able to detect whether the virus invasion, resulting in unnecessary losses.

With the continuous development and progress of the society, I believe that in the future development, the growth space of computer and network system will be very broad; However, today's computer security problems have not been solved, can not protect users' personal information. Therefore, only by constantly strengthening computer security technology and constantly improving the relevant software design, can we enhance the role and value of the computer. In the actual work process, relevant personnel can hire professional software team, combined with the status of the computer to formulate targeted solutions, so as to ensure the stable operation of the computer system, to ensure the security of computer software development.
