Part Number E16543-01
Welcome to Oracle Database Security Guide. This guide describes how you can configure security for Oracle Database by using the default database features.
This preface contains these topics:
Oracle Database Security Guide is intended for database administrators (DBAs), security administrators, application developers, and others tasked with performing the following operations securely and efficiently:
Designing and implementing security policies to protect the data of an organization, users, and applications from accidental, inappropriate, or unauthorized actions
Creating and enforcing policies and practices of auditing and accountability for inappropriate or unauthorized actions
Creating, maintaining, and terminating user accounts, passwords, roles, and privileges
Developing applications that provide desired services securely in a variety of computational models, leveraging database and directory services to maximize both efficiency and ease of use
To use this document, you need a basic understanding of how and why a database is used, and basic familiarity with SQL.
Our goal is to make Oracle products, services, and supporting documentation accessible to all users, including users that are disabled. To that end, our documentation includes features that make information available to users of assistive technology. This documentation is available in HTML format, and contains markup to facilitate access by the disabled community. Accessibility standards will continue to evolve over time, and Oracle is actively engaged with other market-leading technology vendors to address technical obstacles so that our documentation can be accessible to all of our customers.
