Security Inspectionn Study And Tool Development Based On Isolated Information System

With the development of the Internet in China and the deepening understanding of the importance of information security, many enterprises physically cut off office network from the Internet and other public networks, so as to avoid the damage of rampant trojan horses and viruses, and prevent interior information from being stolen.Given this fact, conducting corresponding inspections regularly, and establishing rational inspection procedures will effectively strengthen system security. In real practice, due to difficulties in data collection and analysis, inspection will not always reflect all problems.In this context, the study analyzed the threats to current isolated information systems, identifying the key technologies and main characteristics of basic network structure and network security, formulate a pertinent inspection process and specific procedures, and developed an inspection platform able to collect data, process data and produce reports. Standardized function and compatibility tests were carried out to evaluate the platform's effects. The study results have been successfully applied to the security inspection works of relevant enterprises and institutions.This project has some theoretical value and practical significance.
