Research And Implementation Of The Operation And Maintenance Audit Of The Character Terminal Session Based On SSH

Operation and maintenance audit system is an application system for security management of system maintenance operations. It isolated the operation and maintenance personnel and operation and maintenance server through the fortress machine, in order to prevent malicious attacks and damage. However, the operator’s account rights and operation and maintenance operations also need security protection. SSH protocol as a remote login security protocol, can be very good to meet the operation and maintenance of the operation and maintenance of the terminal operation and maintenance of access. Therefore, it is a very meaningful work to develop a set of operation and maintenance audit system to meet the needs of the SSH session.Firstly, this paper finds and summarizes the existing problems which they will lead to after deep research and analysis of the situation of operation and maintenance work. There are four main issues:SSH session reuse rate is low, operation and maintenance process password management is complex, record file security level is low, operation and maintenance operation and operation and maintenance personnel is not suitable. Then, this paper researches the technology used for solving these problems and describes their theories briefly After that, system architecture committed to addressing the problems is designed. With user needs, the overall design and detailed design of the system are completed according to software engineering methods. In this part, the functional composition of the system and the workflow of important module are introduced. The SSH operation and maintenance session audit system designed in this paper has good performance in portability and security, it can be well integrated with other systems. At last, with the open source library libssh, development of the system is accomplished. An audit system module which can process agent forwarding, data logging and process track playback SSH character operation and maintenance audit sessions is completed.With the integration of the information operation and maintenance audit systems, this system has been fully tested in the actual operation and maintenance environment. It can improve the security of operation and maintenance.
