事务日志及其解析在医院信息安全中的应用

Transaction log and its analysis applied to hospital information security

目的:探讨事务日志及其解析在医院信息安全中的应用,维护数据安全、防止数据丢失、处理数据异常。方法:介绍事物日志在日志备份及数据库恢复2个方面的应用,分析日志解析在医院信息系统中具体操作方法,即采用Oracle中自带的Sqlplus与Ftp工具对日志进行解析。结果:通过对日志文件的追踪与剖析,可准确查明事件的前因后果,及时发现程序漏洞,找回丢失数据。结论:日志备份、数据库恢复及日志解析三大应用是保障医院信息系统安全运行的重要手段与方法。突破日志解析目前存在的局限性将是今后的重点研究方向。

Objective To study transaction log and apply its analysis to hospital information security to prevent data loss and treat abnormal data. Methods The application of transaction log was described in log backup and database recovery, and the optration of log analysis was explored in HIS. Sqlplus and Ftp tools in Oracle were used to analyze the transaction log.Results The tracking and analysis of the log files contributed to making clear the incident, finding program bug, getting back lost data. Conclusion Log backup, database recovery and log analysis were of great importance for hospital information security,and log analysis has to be emphasized on in the future.
