  • This paper will feature designs for security vulnerability based on MS-SQL Database and OLE connectivity by checking the MS-SQL database password policy, the user account password access attempts, a user without password, and password does not be changed for a period of time. This paper uses the MS-SQL database and C++ linkage in order to use the OLE DB function. The design module should judge presence or absence of security vulnerability by checking database password policy, the user account password access attempts, a user without password, password does not be changed for a period of time. The MS-SQL database password associated with a feature, judging from the many features allows you to check for security vulnerability. This paper strengthen the security of the MS-SQL database by taking the advantage of the proposed ability.

  • In this paper, we discuss the development of an integrated HMI system based on OPC(OLE for Process Control) to control and monitor an automation equipment in the diverse environment. We implement an embedded OPC server according to the OPC standard which is proposed as the communication standard mechanism in the process control field, and design the interface module in which the output data of the OPC server can be connected to various HMI environment such as the local application, intranet client and Web page. This paper will be contributed in the HMI system implementation for the ubiquitous environment because it is possible to make remote control on the network and Web monitoring as well as the connection and data exchange of heterogeneous equipments by applying to various control systems.
