Chapter 4. Security

Oracle provides a variety of features that can help secure your database from unauthorized access and can help protect your data from being seen or manipulated by unauthorized users. This chapter focuses on the major security-related concepts for Oracle—authentication, profiles, privileges, roles, and auditing—and specifies the syntax for controlling security in an Oracle database.

In addition, we include brief discussions of some of the more advanced security options for Oracle. Detailed information on these more specialized and/or extra-cost options is outside the scope of this book. If your site has purchased the Advanced Security or Label Security options, consult Oracle documentation for information.
