Last month we talked about basic Oracle security, and set out principles for a top notch secure system. These included passwords, the principle of least privilege, and roles.

This month we journey into the fascinating world of Oracle Network Security. The topics covered will not involve the Oracle Advanced Security option: it's too big to cover here, and it is an added expense that many companies do not want. Instead, we will go over basic network security that can be implemented by anyone who uses Oracle. It is built in and so is already part of your system.
