Study on the Technical Security Factor for the Implementation of Secure DB System

Sunhee Yoon

This paper introduces Database security to prevent the rapidly increasing issue of private informationleakage. The Database security examined in the paper separates into DB access control area and DBencryption area which further leads the paper to analyze the factors of the two areas and suggestnecessary elements for creating stable Database security. In addition, the paper examines previous DBsecurity programs by areas and analyzes pros and cons from the tested result. The experiment indicatedthat while DB access control presents less degradation and reduced the need to modify the existing DBMS since the access control operates at the end point of the network, DB encryption presented strength inprotecting the data from unauthorized access. On the other hand, DB access control is less useful inpreventing the attack in advance which leaves the log to enable tracking afterward while DB encryptioncan only be operated by limited types of Database and causes degradation due to system load and showshigher percentage of failure when creating the system. This paper examines characteristics of Databasesecurity areas in order to be used as a reference for institutions or companies seeking stable Databasesecurity.
