Introduction

As most of the applications that are using Oracle Databases are two or three tiered, communication over network is involved. The network and its components are probably the most vulnerable area due to the increased amount of exposure. Network communication layer attacks are usually one of the hardest to detect as the majority of them do not require a direct connection to the database server, but instead are targeted towards the network traffic and the data in flight. In the following chapter we will present some of the most widely used attack and defense techniques against the Oracle network components.
