Design And Implementation Of Oracle Database Operation And Maintenance Control System

In the process of database information security protection,it is not only necessary to avoid the important information leakage hazards brought by external attacks,but also need to always pay attention to the security risks of database operation caused by internal violations,especially the security risks brought by database operation and maintenance process.At present,the operation and maintenance security audit system is limited to the operation and maintenance of the database for the responsibility of the accident,and there is no reasonable control of the authority and operation of the operation and maintenance personnel.Therefore,it is urgent to strengthen operation and maintenance control technology in database operation to achieve security.Based on the security of database operation and maintenance operation,this paper studies the defects and risks existing in the current database operation and maintenance operation process,introduces the agent mechanism and audit technology to design and implement the Oracle database operation and maintenance control system.The specific implementation contents are as follows:(1)The system supports prior approval in the early stage of operation and maintenance,and can set time strategy,designate operators,allocate operating equipment and configure operation and maintenance rules for a certain operation;(2)Support in-process control in the operation and maintenance process.By analyzing and restoring the TNS protocol applied in Oracle database,recording operation,data forwarding and constructing syntax parsing tree for rule filtering,the source,time and content of operation and maintenance operations can be monitored and recorded in real time in the operation and maintenance process of the database.In this way,we can analyze whether there are abnormal behaviors of operators and realize fine-grained control of operation and maintenance operations;(3)Support post-audit after the completion of operation and maintenance,display the operation and maintenance records in the form of character type and screen recording,and use Apriori algorithm to carry out abnormal detection on the structure of SQL statements to ensure the security of operation and maintenance operations.At the same time,regularly generate operation and maintenance reports for analysis and statistics of operation and maintenance operations.In this paper,the agent mechanism and audit technology are introduced to analyze and test the Oracle communication protocol,and the operation and maintenance control and audit accountability are effectively combined to ensure the accurate execution of operation and maintenance operations and the efficient implementation of audit operations.
