Part I describes how to manage user authentication and authorization.

• Managing Security for Oracle Database Users
  You can manage the security for Oracle Database users in many ways, such as enforcing restrictions on the way that passwords are created.
• Configuring Authentication
  Authentication means to verify the identity of users or other entities that connect to the database.
• Configuring Privilege and Role Authorization
  Privilege and role authorization controls the permissions that users have to perform day-to-day tasks.
• Performing Privilege Analysis to Find Privilege Use
  Privilege analysis dynamically analyzes the privileges and roles that users use and do not use.
• Configuring Centrally Managed Users with Microsoft Active Directory
  Oracle Database can authenticate and authorize Microsoft Active Directory users with the database directly without intermediate directories or Oracle Enterprise User Security.
• Managing Security for Definer's Rights and Invoker's Rights
  Invoker’s rights and definer’s rights have several security advantages when used to control access to privileges during user-defined procedure executions.
• Managing Fine-Grained Access in PL/SQL Packages and Types
  Oracle Database provides PL/SQL packages and types for fine-grained access to control access to external network services and wallets.
• Managing Security for a Multitenant Environment in Enterprise Manager
  You can manage common and local users and roles by using Oracle Enterprise Manager.
