Database
The
rights for users to access a database should be controlled based on user
levels.

owner of application software has full control access to the software. It is
not recommended to grant an account with full control access of the software it
owns.

Database Management Permission
With
the database management permission, users can change storage and configuration
permissions of the database. Therefore the management permission of users must
be defined clearly. If a user only has to store data to a database, the user
only needs storage permission.

Users
are given the read permission, write permission and execute permission of files
and access permission of folders.
Owner of database Service or Daemon
The
owner of the database server or daemon must have a designated account.
Public Permission of the System Directory
Table
The
system directory table contains much useful information for database. To
prevent unauthorized users from accessing a database, only public information
can be reserved in the system directory table. Important information of the database
must be stored in other places of the OS.
Database User
Discrimination and Authentication
Discrimination
and authentication ensures that only authorized users can access the database.
User Account Authorization
If
any account in the OS is authorized to access database, the security of the
database may be under threat. Therefore only the users having the permission
can access database.
