Digital Campus System Of Safety Audit And Analsis

The building of Digital campus has been the most useful way to enhance the competitiveness of education and widen the influence of university. In recent years, with the widespread of computer virus, security of Digital campus system has been one of the most important issues on building Digital campus system. However, security audit is one of ways to protect network security. It's good for us to build the digital campus system.This paper summarized the features of the internal network user's behavior and the abnormal behaviors, and summed up the feature detection of behavior events, such as content correlation and time serial correlation. According to arithmetic of the two correlations, a distributed user's behavior audit system is designed and implemented based on an openxdas which is open-source code. It can collect the distributed user's behavior information through the network and host, and carry out security audit analysis through matching rules. This article also focuses on design and implementation of the time-series statistical detection model. It can collect the distributed user's behavior information through the network and host, and carry out security audit analysis through statistical detection.This system use C language and C# language to compile on visual studio 2008. Now the system has completed a model of time-series statistical detection. System makes log data a preprocessing, and then sent to the server-side to make an analysis. At last, system uses a platform to display the results of security audit, and results of real-time display to remind the user whether there is any abnormal event.
