0 introduction
In recent years, although computer information systems have been established by the public security organs throughout the country, there are still problems, and we are aware of the complexity of the cyberworld, and the security of the computer information network as a public security organ deserves greater attention. The security of public security information in the public security organs is of special importance and importance. We must guard against attacks by “blackers” and hostile elements at home and abroad against the computer information network of public security. Strengthening the security index of the public security computer information network and ensuring the security of information are central issues in the development of the public security computer information network. The enhanced information security management of the public security system has led to significant improvements in the efficiency and effectiveness of the public security system as a whole, as well as to further improvements in service functions. The current computer information system for public security in our country can help us to organize information efficiently, and the sharing of resources can be achieved once effective information is entered into the database. Thus, the computer information of the public security organs plays an important role, and we must make great efforts to improve the security management of the computer network。
1 overview of computer information security
In ensuring the security of computer information, we can use relevant technologies and management in information processing systems to protect the security of information, which is to protect the integrity and control of information systems. The rapid development of technology in the information age has made our lives dependent on computer networks, which have many characteristics, such as openness, diversity of connectivity and interconnectivity, but which also have technical disadvantages such as vulnerability to malicious software to enter and breed viruses. We must confront the weaknesses of computer networks in terms of security management and protection. Computer information security includes several aspects: hardware security, hardware security, including the security of the medium in which information is stored, and computer system software security. We need to take effective measures to protect hardware from viruses and maintain normal working conditions. The second is software security, which is the security of computer internal network systems. Invasion of software can lead to web pages being tampered with, destroyed and personal information being lost and maintenance functions being illegally duplicated. The third is operational service security, that is, ensuring the proper functioning of the systems in the computer network while ensuring a normal flow of information, for which we should monitor and manage the functioning of the computer system at all times, issue timely alerts where problems arise and take remedial action to address insecurity. Fourth is data security, which means effective measures stored in the network to protect data from malicious manipulation and use, to protect data security against data addition, deletion and duplication, and to protect data for our most fundamental purpose of protecting network security. To achieve the goal of protecting cybersecurity, several requirements must be met: first, the confidentiality of information should be strictly ensured and information should not be illegally disclosed. Secondly, it is to strictly ensure the integrity of information, to protect it from unlawful manipulation, deletion, insertion and destruction, and to protect it from disorder and loss. Protecting the integrity of information is our primary purpose of protecting information security. Third, the availability of information should be strictly guaranteed, mainly for authorized users, and regular access to information should be guaranteed. It is then necessary to ensure the control of information, primarily with regard to the authority authorizing the information, which ensures control over its dissemination and content, as well as some control over the flow of information within a given mandate and the mode of movement. Finally, it is necessary to strictly ensure that information is reviewable, that web-based information browsing leaves search marks and that both parties using the network for information exchange keep records。
1. 1 inadequate security and reliability of network systems themselves
The security of network systems includes, inter alia, information and communication transmission channels and the security of network communications equipment. According to the current state of the country's public security computer network system, with the exception of some self-built fibre-optics and microwave channels, most of the communications channels are rented, such as mail and telecommunications lines, frame relays, dnn, isdn, etc., but there are some security risks inherent in these channels. For example, the lack of stability and quality of the circuits, combined with excessive middle links, could affect the functioning of normal network operations if problems arose and no first-time testing and maintenance were performed. In particular, where there are no dedicated lines but can only be accessed by dial-up numbers, the increase in dial-up numbers can make networks vulnerable to intrusion by illegal users. On the other hand, the network system consists mainly of network equipment, such as routers, switches, which, while providing remote maintenance and remote dial-up access, has security risks that are controlled by illegal users, ultimately leading to a reduction in the security of the overall public security computer network system。
1. 2 lack of security and confidentiality of information systems
The security of information systems includes, inter alia, security of operating systems, security of databases and security of applications. The operating system is a public platform for applications and service operations. Currently, most of the public security services use microsoft's windows nt and windows98 operating systems with low security levels and limited user certification, access control and security audit capabilities. The security of the database is the platform for the operation of the public security operational information system, which currently does not have encrypted protection of information that requires priority confidentiality, much less a ca identification system. Public security information systems often use systems that are downloaded free of charge on the internet and may carry viruses that threaten the security of public security information systems。
1. 3 inadequate awareness of the safety of management personnel
Public security technicians are mistaken in their view that the public security information network is a dedicated network and is not subject to “blackers” intrusion, and that the public security information network, as the basis for the security of national information, is seriously affected by any intrusion. Therefore, we must increase security awareness and manage information network security precautions, while paying attention to gaps in network internal security checks。
1. 4 inadequate capacity to manage and address issues
At present, some of the public security information network systems do not have adequate audit management functions, and if the network operates, it will not be possible to diagnose it in a timely manner, make it even less possible to effectively detect attacks, protect the site and report in a timely manner, thus delaying the best opportunity to locate hackers. In response to the current security concerns in the computer information network system of the public security organs, we need to raise security awareness, improve technical skills and improve the security management system of the computer information network of the public security organs。
Optimizing the security management of the computer information network for public security
We can begin in several ways to address the security risks of the current computer system for public security and to enhance the security of information on the public security network。
2. 1 increased risk prevention awareness among public security technicians
The web-based world is complex, and the internet poses many security risks, and the public security information network, as a branch of the network, can cause a malfunction in the operation of the entire information network system if problems arise at any point. Therefore, raising awareness of the safety and security of staff is the main task, and it is in the day-to-day work of the staff that the concept of security and safety is applied to improve the level of management of the public security information network as a whole。
2. 2 enhanced security education training
The information network system has been evolving, and our safety protection against cyber-risks has to be updated to respond to the invasion of cyber-viruses at all times. The current computer-based public security information network continues to have a number of hazards. We need to improve the professional skills and comprehensive quality of our staff. This requires increased technical education of our staff to avoid the negative effects of mismanagement。
2. 3 enhanced user and password management
In managing the security of the public security information network, greater attention must be paid to the management of user names and passwords. The management of users and passwords can be strengthened in several ways, including by setting password protection in the information management of the public security network, and by placing user names and passwords on the public security network when searching for information. The security level of the password is also subject to some regulation, which may be in the form of a digital combination of letters。
2. 4 establishment of professional security management teams
The establishment of a professional team of the public security network is an essential requirement for the security of the network. In the construction process, we need to strengthen the management of the infrastructure, deal with irregular operations in a timely manner, and conduct regular monitoring and maintenance of network security and safety. Management needs to place greater emphasis on the security management of network information and detect violations in units and departments in a timely manner。
3 concluding remarks
In the light of the above, there are a number of security risks in the security management of the public security computer information network, and the security awareness of the public security network needs to be further enhanced. At the same time, we need to develop a well-developed management system to ensure that the concept of security prevention is translated into practice. At present, the public security system is gradually being improved, allowing for timely responses to the larger risks that arise in the network, as well as for small risks. But we need to further improve and strengthen the security management of the public security information network。
