What are the protection strategies for information security

　　1. Database management security

　　In the specific computer network database security management, there are often all kinds of computer network database security hidden dangers caused by human factors, which have a greater adverse impact on the database security. For example, due to improper human operation, it may leave harmful programs in the computer network database, which will greatly affect the safe operation of the computer system and even bring huge economic losses to users. Based on this, modern computer users and managers should be able to take effective control measures according to different risk factors, pay real attention to security management protection from consciousness, and strengthen the security management of computer network database.

　　2. Enhance safety awareness

　　Everyone is often used in everyday life, various user login information, such as online banking account, weibo, WeChat and pay treasure, such as the use of this information is inevitable, but at the same time also became criminals steal these objectives, in an attempt to steal the user's information, the use of the logged in user terminal, the data within the user account information or money stolen. What is more serious is that many users in the current society are related to each account, once the theft of a successful account, the theft of other accounts is easy to bring greater economic losses to users. Therefore, users must always be vigilant, improve their security awareness, refuse to download unknown software, prohibit to click on unknown website, improve the security level of account password, prohibit multiple accounts to use the same password, strengthen their own security capabilities.

　　3. Scientific use of data encryption technology

　　For the computer network database security management, data encryption technology is an effective means, it can maximize to avoid and control the computer system by the virus damage, so as to protect the computer network database information security, and then to protect the vital interests of relevant users. Data encryption technology is characterized by concealment and security, specifically refers to the use of some language programs to complete the calculation of database or data encryption operations. At present, the most widely used computer data encryption technology in the market mainly includes secure communication, anti-copy technology and computer keys, etc. These encryption technologies have their own advantages and disadvantages, which have important practical significance for protecting user information and data. Therefore, in the computer daily safety management of network database, adopt scientific and advanced data encryption technology is necessary, in addition to his invasion of users can greatly reduce the virus program important data information, also can in the user's data information after being invaded, still have the ability to protect the data and information leakage problems. It should be noted that the computer system has a huge amount of data information, and it is obviously unrealistic to encrypt and protect each piece of data. Therefore, it is necessary to use the hierarchical division method to encrypt and process information reasonably according to the importance of different information, so as to ensure that important data information will not be destroyed or stolen.

　　4. Improve hardware quality

　　Factors that affect computer network information security is not only the software quality, and quality of hardware, and there are some difference between the two hardware systems, on the basis of considering the safety, also must pay attention to the use fixed number of year of hardware problems, as an important constitutive requirements of computer hardware, it has increased over time the characteristics of its performance will gradually reduce, the user should pay attention to this point, to strengthen in the daily maintenance and repair. For example, if a hard drive has an optimal life of two years, try not to use it for more than four years.

　　5. Improve the natural environment

　　To improve the natural environment means to improve the dust, humidity, temperature and other use of the computer environment. Specifically speaking, it is in the daily use of the computer to regularly clean up the dust on its surface, to ensure that the work in its clean environment, can effectively avoid the aging of computer hardware; It is best not to use the computer in the environment with too high temperature and humidity, pay attention to the external maintenance of the computer.

　　6. Install firewall and anti-virus software

　　Firewall can effectively control the access rights of the computer network, through the installation of a firewall, can automatically analyze the security of the network, the access to illegal sites to intercept, filtering the message may exist problems, to a certain extent to enhance the system's ability to resist, improve the security index of the network system. At the same time, also need to install anti-virus software, this kind of software can intercept and interrupt the virus that exists in the system, to improve the computer network security greatly.

　　7. Strengthen the application of computer intrusion detection technology

　　Intrusion detection is mainly aimed at the operating system of data transmission security detection. Through the use of IDS(intrusion detection system) intrusion detection system, abnormal phenomena between the computer and the network can be found in a timely manner and users can be prompted by the form of alarm. In order to better play the role of intrusion detection technology, the use of this technology will usually be supplemented by a series of technologies such as password cracking technology, data analysis technology, to ensure the security of computer network.

　　8. Other measures

　　Security measures for computer network security also include improving the awareness of account security management, strengthening the application of network monitoring technology, strengthening the computer network password setting, installation of system vulnerability patches and so on.
