Chapter 11. Users and Security

If a company has more than one employee who needs access to the Oracle database, then the security of the database is a prime concern for the DBA. The data integrity of the database and the level of security in the database are maintained, in part, by preventing unauthorized or unintentional actions in the database.

Database security can be divided into roughly two areas: data security and system security. Data security includes monitoring and assigning users permissions to the various objects in the database. System security covers the user login process, how much disk space is assigned to each user, and what kinds of actions each user can perform.
