Slide 11 - Fundamental data security requirements Introduction Making data available to the authorized users & application programs Slide 11 - Fundamental data security requirements Introduction The ability to prevent the effective denial of an act. Slide 11 - Countermeasures To protect databases against these types of threats four kinds of countermeasures can be implemented: Access control Inference control Flow control Encryption Slide 11 - Access control The security mechanism of a DBMS for restricting access to the database as a whole Handled by creating user accounts and passwords to control login process by the DBMS. Two types of database security mechanisms: Discretionary security mechanisms (DAC) Mandatory security mechanisms (MAC) Slide 11 - A DBMS typically includes a database security and authorization subsystem that is responsible for ensuring the security portions of a database against unauthorized access. Inference control The security problem associated with databases is that .
