1 Traditional colleges and universities Website production management model
Usually, the campus website is composed of the school homepage, department website, college website, student association website, etc. In daily work, some special pages will be established as required, and the network management center will provide server and website system services. In the past management, most schools were responsible for the design and production of the school homepage in the network management, and the publicity department was responsible for the data update and maintenance of the school homepage, such as campus news, notices and announcements. The websites of other departments, colleges and student associations are designed and produced by themselves, and the data is updated and maintained later. This decentralized construction mode has brought many problems to the management of campus websites, such as non-uniform technical standards, long construction period, many security risks, various construction styles, and so on.
2 Site management of website group system
The website group system is an information management system for the construction, management and maintenance of multiple web sites. It has the characteristics of unified planning, unified specifications and unified standards. It can be managed uniformly or independently, and can build multiple sites with unified appearance and style in a short time.
In the site management of the website group system, the school homepage, department website, college website and student association website are independent management sites. The system administrator formulates the specifications, standards, and styles of website construction, provides website construction templates, and adds, modifies, and improves various website components as needed, such as website navigation, article lists, pop-up windows, message boards, online surveys, calendars, weather forecasts, electronic maps, and so on. After the system administrator allocates website space and website administrator authority to each website, the website administrator can design, build and maintain the website as required, and assign column administrator authority as required.
The website group system adopts flexible user rights management, as shown in Figure 1. The website group system allocates management permissions based on websites and columns. Site administrators can manage one or more sites, and a site can have multiple site administrators. The website administrator can design the website, make pages, set columns, etc., or publish information in the website. The column administrator can only publish information in the assigned columns. A column administrator can have the right to publish information on one or more columns, and can also have the right to publish information on different website columns. For websites that need to strictly control the release of information, you can set an information release review process, so that the information added by the administrator will not be published directly, and only after being approved by a higher level administrator will the information be published on the website.
3 Web site cluster system deployment network model
The website administrator designs, makes and manages the website on the website group management server through the campus network. After completing the website design and production, the website needs to be published to the website group publishing server, and both campus users and off campus users can only access the website group publishing server. In order to improve the security of the website group management system, the website group management system can add a separate database server and data backup server, and assign internal IP addresses to the website group management server, database server, and data backup server through a three-tier switch to prevent off campus users from accessing and attacking the core services of the website group system.
4 Website information statistics of website group system
The completion of website design, production and information release is just the first step of website management. Daily website management must also be able to understand the operation status of the website at any time, such as the number of visits and popularity of the page and other information, and use the analysis results to finally make adjustments to the relevant content. Only in this way can the website be optimized, so that the pertinence of the website construction is greatly enhanced, so as to improve the website's access and give play to the website's due effect. For example, through the analysis and statistics of the access logs, we can get the peak hours, monthly visits, annual visits, and total visits per day. Through the analysis and statistics of website content, website columns and administrators, we can get the statistics of information released by administrators, the statistics of column news, the ranking of column information, and the statistical ranking of visits to published information.
5 Security management of website group system
For traditional website management, the homepage of each department, college and student association is designed and produced by itself, and some are directly handed to students. In the development and production, each site lacks a unified plan and standard, and a variety of development languages are selected, such as PHP, ASP, JSP NET and other databases, such as SQL SERVER, MYSQL, ACCESS, etc. Due to the lack of experience in website design and production, the site produced has many loopholes, and often downloads ready-made program code from the network. These codes are often implanted with trojans or have loopholes, which makes the website easy to be hacked, hung up, implanted backdoor programs, etc. A site invaded will cause the entire website or even the entire server to be controlled by hackers, It seriously affects the security of the server.
Website group system can improve information security and system security through various ways. The use of modular components in website construction not only reduces code writing in the development process, but also greatly reduces security risks; The access log can record the access records of all website visitors, and also record the log information such as SQL injection and XSS cross site script attack of the visitors to the website, so that the administrator can view such information at any time and optimize the website security in a timely manner; The station cluster monitoring mechanism can view the administrator users currently logged in, and can restrict the administrator's IP address to log in to the system to effectively protect the maintenance security of the website; Anti DDOS attack configuration can block malicious attack users from visiting websites.
Through the system backup mechanism, the administrator can back up and restore the website content and data information at any time during the website maintenance process, or can set the automatic backup function to regularly back up the website content and data information, thus effectively ensuring the security of the data of each website.
6 Conclusion
Compared with the traditional website construction management mode, the website group system has obvious technical advantages and can well meet the needs of campus website management. Unified planning, standardization and standards are conducive to centralized deployment, reducing repeated server investment and management difficulty; The use of template development and modular design of application functions can effectively reduce the time for website design and development, unify the website style and shorten the construction period; The use of hierarchical authority management mechanism and information audit process management ensures the standardization and order of website information release; Reduce the code writing in the development process, reduce the technical threshold of website management and maintenance, and improve the security of the website.
