Research on Key Technology of Computer Security Monitoring System

The development of information technology has brought new challenges to information security. Computer security monitoring system is an effective mechanism to ensure information security. It protects and monitors all kinds of information and user operation in local or remote computer through data acquisition, analysis and processing, rule discrimination, violation prevention and full record. This paper mainly studies the key technologies of document, text and user operation, and analyzes the realization mechanism and application environment of these key technologies by experiment. It is very important to strengthen the system function and improve the efficiency and stability of monitoring.
