3 Terms, Definitions and Abbreviations
3.1 Terms and Definitions
For the purposes of this standard, the terms and definitions defined in GB 17859-1999 and GB/T 20271-2006 and those listed below apply.
3.1.1
Security of database management system
Characterization of the confidentiality, integrity and availability of the stored, transported and processed information in database management system.
3.1.2
Security technology of database management system
All security technologies required for realizing the security of all kinds of database management systems.
3.1.3
Security subsystem of database management system
A generic term for security protection devices in database management, including hardware, firmware, software and combined entity responsible for executing security policy. It establishes a basic security protection environment of database management system and provides additional user service required by security database management system.
Note: SSODB (security subsystem of database management system) is TCB of database management system according to the definition of TCB (trusted computing base) in GB 17859-1999.
3.1.4
SSODB security policy
A group of rules to manage, protect and distribute SSODB resource. One SSODB may have one or more security policies.
3.1.5
Security function policy
Security policy adopted to realize the function required for SSODB security element.
