Building secure database applications is done on the assumption that the database is already operating securely. To ensure this happens, you often have to perform certain tasks to create a tighter security implementation. There are many important lessons in this chapter.

Securing database schemas means ensuring not only new schemas are created and managed properly but also that the default schemas are secured. The default schemas and their passwords are well known. There are several ways to prevent unwanted and unauthorized users from connecting to these well known and highly privileged accounts. Several techniques were shown for applying the defense in depth principle.

An understanding of Oracle’s use of passwords is necessary because password authentication represents the most common authentication mechanism to the database. The database supports both password complexity routines and password profiles to support the secure and proper use of passwords.

Oracle’s default roles exist today for legacy reasons and should rarely be used, and revoking existing privileges and limiting grants to the user group PUBLIC is essential for securing the database.

A final necessary piece of the security puzzle is network security. The entire security of an application and database can be subverted through poor network security. The database provides several ways to prevent this from happening. Applying security at the network tier ensures all the links in the security chain are strong.
