VNC-based Graphical Event Analysis System In Operation And Maintenance

Development of IT technology is proposing higher and higher demands on the security of information systems.Traditional information security focuses on the prevention of external hacker attacks, and network access control of the border, while the lack of effective management of internal staff, especially the operation and maintenance personnel with higher information system access rights, which the enterprise operation and maintenance safety audit appear particularly important. VNC as a cross-platform remote control software is increasingly being accepted by businesses and individuals in the security systems. However, the direct application of commercial VNC software has a large amount of data and redundant information, and difficult to position the client’s abnormal operating defects in a short time. A client software which can quickly locate operations on the server is designed in the thesis, and the operation is carried out by the client event log management, remote monitoring log extraction system. The paper extends the functionality of VNC, the main work is as follows:(1) Learn and revise VNC source code and transform the client to log on to the server via VNC and record a client server operation data stream.(2) To write the player to resolve the interested in the data stream for playback. which is to locate the abnormal operation of the client quickly.Monitoring the functionality of the client operating.(3) Parsing the data stream, extract the data stream playback operation events corresponding to the picture, the picture processing input carried by the OCR software to recognize the text, the last operating events integrated into the log file.The system does not need to install agent software on the client, you can achieve the requirements of the audit, and enhance the security of the system. The system for enterprise audit system can greatly improve the efficiency of audit work, efficient containment of illegal operations in the network, and the system will also bring improved efficiency and profit growth.
