The computer management system of 1. 1 was hacked.
Systems are usually hacked. Some hackers use some illegal means to invade the enterprise computer information management system, which leads to the destruction of the system, the modification of the enterprise website information, and the theft of internal business secrets. At the same time, some information that is not conducive to the development of enterprises will be attached to the website. If the situation is serious, it will lead to computer paralysis, which will cause immeasurable economic losses to enterprises and bring certain negative effects to society.
1.2 Spreading computer viruses and other destructive programs
Some people often download a large number of hacker viruses on the network, implant these viruses into the nodes of the computer network, and attack the computer network system, which will eventually slow down the system, then cause the computer to crash, and finally lead to the system crash. From the management and technical factors, poor management of managers is an important reason for this situation. However, the lack of firewall in computer system is the key factor of security problem.
1.3 Destroy computer system data and programs
Some hackers often seize the loopholes in the system to illegally attack the computer network system and remotely control the computer system, so that these important files and materials in the computer system are deleted, and even the deleted files and materials cannot be recovered at all, which makes the computer network system unable to operate normally and leads to the paralysis of the computer network system [2].
1.4 Destroy the computer network system
In many cases, hackers generally use illegal programs to attack the computers of state organs and units, modify and change important data and files in the computers, and some even successfully cracked the passwords of computer systems and set up personal accounts. Stealing the secrets of the state and enterprises by this means makes the whole computer network controlled by them, which brings great harm to society.
2 computer information management system security countermeasures
2. 1 Strengthen the security prevention and management of computer information systems
Improving the management technology of computer information system is an important content to improve the system security and an effective means to ensure the normal operation of the system. Therefore, we should establish a perfect computer management system's authority control, access function, security management and technical service module. Strengthening security prevention and control is not only a key measure for security prevention and control of computer information management system, but also an important measure to ensure the safe operation of the system. In addition, we can also strengthen the use of system firewall. Firewall is a security barrier between the system and the outside world, which can effectively prevent the invasion of illegal users and effectively provide security for computer systems.
2.2 Ensure that the computer management system structure design is scientific and reasonable.
Enterprises should pay more attention to information management system and improve the rationality of computer management system design. On this basis, they should focus on the network operation quality and network security of computer information system, formulate the optimal scheme that conforms to themselves, ensure the rationality of design, and then ensure the security of computer information management system. In addition, in the process of data dissemination, data is often stolen, which is caused by the limitations of the Internet. Therefore, in this case, various ways should be taken to realize the security control and prevention of the computer information management system on the LAN to ensure the safe operation of the computer information management system [3].
2.3 gradually establish and improve the computer information management system and mechanism.
Perfecting the security management system and mechanism of computer information system can effectively guarantee the security of computer network system, standardize the security management and maintenance of the system, reduce the system intrusion events, and provide a foundation for the normal operation of the system. On the one hand, we should turn our attention to the hardware equipment of the computer information management system, always pay attention to the running situation and environment of the computer information management system, and carry out irregular testing and maintenance; On the other hand, we should do a good job in the confidentiality of computer information management system, which is also the key content of system security management. We should reasonably use encryption technology to prevent the disclosure of confidential documents and information, which greatly improves work efficiency.
2.4 Establish employees' awareness of system safety.
In addition to strengthening the security of information management system in technology, employees should also be alert to computer information security issues in their work, put safety first and deal with security issues in a reasonable way. With the abnormal situation of the system, employees should deal with it promptly and effectively to minimize hidden dangers.
3 Conclusion
With the rapid development of information technology, computer information security has been paid more and more attention. For the security management of computer management system, only by establishing a perfect network security management system can we prevent viruses from invading and stealing important information resources. In addition, strengthen the protection of databases and systems, so that the functions of computers can be brought into normal play and the information management system can run safely and effectively.
