Oracle 数据库认证：梦想开始的地方（oracle 数据库认证）

Dreams start with an idea, and for Oracle databasemakers, the idea begins with a successful database authentication system. Oracle’s database authentication technology takes the form of an operating system-specific system or a network-based technology such as Oracle Advanced Security. By requiring an authorized user to provide a valid user ID and password to gain access to the database, Oracle’s database authentication technology makes it much harder for hackers to gain control of the system while still allowing legitimate users to access the system.

In this article, we’ll take a closer look at the database authentication system that Oracle provides. We’ll explore how it works, how to configure it and the types of authentication methods available to Oracle database administrators.

The first step when setting up database authentication is to create a database user account that is going to be used to authenticate the database connection. Oracle includes an Enterprise Manager GUI (Graphical User Interface) which allows database administrators to easily create and manage the user accounts. Once the account is set up, Oracle can assign the user an authentication method, such as a password, challenge code, public key infrastructure, biometric method or a combination of methods.

The database administrator will then configure the system to validate the user’s credentials by either using the database password file or a centrally stored database service. This helps ensure that the database is only accessed by authorized users. Additionally, Oracle provides a “login lockout” mechanism to help protect the database from brute-force login attempts. This allows database administrators to specify how many unsuccessful login attempts a user can make before they are automatically locked out.

Oracle also provides a comprehensive audit trail that tracks all database access and helps administrators track who is making changes to their database. In addition to the audit trail, Oracle provides a database security warning system that can alert the database administrators to any suspicious activities that occur within the database.

Finally, Oracle’s database authentication system provides support for auditing and activity-tracking features. These features are important for database administrators who want to ensure that their database is secure, and that any suspicious activity is monitored and addressed quickly.

In summary, Oracle provides a comprehensive database authentication system that helps protect databases from unauthorized users, provides support for auditing and activity-tracking features and helps ensure that database administrators have a secure system. While it may take some time to set up and manage, Oracle’s database authentication system is one of the most reliable and secure methods available for any database system.
