Information leakage can be prevented by controlling use of external media (such as CD/DVD, USB drive, and external hard disk) and PCs that are connected to the database, and restricting the removal of data from the database.
Remove external media and printers that will not be used in operations, and restrict connection of external media to which information may be written.
Restrict connections for external media and printers to control the writing of information to these devices.
Prevent leakage of information from PCs connected to the database:
Limit connections of external media to PCs
Implement security measures to make the PC robust
Implement individual authentication for access from the PC
Manage the installed software and monitor the software usage status
Limit connections to printers
