The image illustrates the In-line (bridge) mode of the database firewall deployment. The database firewall intercepts all communications between users or applications in the external network and the database services in the internal network.

The upper part of the diagram consists of two blocks. The left block has icons of Oracle Audit Vault Server and Database Firewall. The Oracle Audit Vault Server is connected to the database firewall. The database firewall icon is then connected to the database firewall traffic source and database firewall and switch source icons in the second block on the right.

The second block on the right is of the database network. It contains multiple icons. The first icon on the top is of the database firewall traffic and switch source. Below that is the database firewall traffic source icon. They are linked to one or more databases on the right which is part of the database network.

The block at the bottom is of the client network. It consists of the users or applications. The clients connect to the database network through the switch, which is part of the client network. It appears that the clients are connected to the database. However, they are connected to the database firewall.
