| With the continuous development of computer technology,the process of information construction in colleges and universities is advancing by leaps and bounds,bringing many conveniences to teaching,scientific research and office work,and the teaching mode has also been greatly changed.As the main platform for external publicity and interaction with users,university websites play an extremely important role in the construction of a smart campus.Due to the lack of security awareness of developers and managers,the security problems brought about are also constantly highlighted.How to let administrators know the situation of website tampering in the first place and minimize the impact of tampered pages on schools is a research topic of great practical significance.In order to solve the problem of pages being tampered with in the management of university websites,this paper designs and implements a tamper monitoring platform for university websites by using the method of webpage tampering detection.First of all,this paper analyzes the current situation of website tamper resistance,and briefly introduces the characteristics of website tamper resistance.Then,through the requirement analysis,the tamper monitoring platform is designed briefly and in detail.Finally,through asp.net technology,a tamper monitoring system for university websites is implemented.The main work of this paper includes:(1)Design a tamper detection strategy for university websites.Using crawler to grab the links of campus websites and download the page codes,a reasonable crawling strategy is planned for the crawler.By comparing DOM tree nodes of different timestamp web page codes,whether the web page has been tampered with or not can be detected.After detecting that the content of the website has changed,disconnect the public network access of the website server through the firewall command interface and push the alarm information to the administrator through the SMS machine interface.(2)Through the requirement analysis of the system and a systematic design,the monitoring system for university websites tampering is developed by Bootstrap framework and asp.net technology,including the functions of information management,detection of task management,tamper site processing,tamper site query,password management,etc.The tamper monitoring system of university websites provides great convenience for the tamper management of university websites.By disconnecting the public network access of the tampered website in time,the spread of tampered information is blocked,and relevant personnel are reminded to carry out emergency treatment in time by pushing alarm information,which has practical significance for promoting the in-depth application of information technology in colleges and universities. |
