Security management is typically performed at three different levels:
??? Database level
??? Operating system level
??? Network level
At the operating system level, DBAs should have the ability to create and delete files
related to the database, whereas typical database users do not need these privileges.
Oracle includes operating-system-specific security information as part of its standard
documentation set. In many large organizations, DBAs or database security
administrators work closely with computer system administrators to coordinate
security specifications and practices.
