Users and Basic Security

Abstract

After you have installed the binaries, implemented a database, and created tablespaces, the next logical task is to secure your database and begin creating new users. When you create a database, several default user accounts are created by default. As a DBA, you must be aware of these accounts and how to manage them. The default accounts are frequently the first place a hacker will look to gain access to a database; therefore, you must take precautions to secure these users. Depending on what options you install and which version of the database you implement, there could be 20 or more default accounts.
