H Ports Used by Oracle Audit Vault and Database Firewall

Oracle Audit Vault and Database Firewall uses specific TCP and UDP ports.

H.1 Ports for Deploying Database Firewall for Targets

You must configure two classes of ports when deploying Database Firewall for targets.

These following two classes of ports must be open in external network firewalls for the following types of Database Firewall deployments:

  • When you configure Database Firewall to protect a target database, traffic directed to that database must be able to pass through external network firewalls to Database Firewall. The ports required are configured in the target's page in Audit Vault Server.

  • You can configure Database Firewall to accept proxy connections which are passed on to the database. The ports required for proxy connections are configured in the Network Configuration page on Database Firewall.

Note:

It is recommend that you do not change these ports.

H.2 Ports for Services Provided by Audit Vault Server

Learn about the ports for services that are provided by Audit Vault Server.

Table H-1 lists the ports for services that are provided by Audit Vault Server. These services are used by external users of the system. Access to most of these ports can be controlled within Oracle AVDF. If you use external network firewalls, then these ports must be open to enable connections from the users, or clients, of these services to Audit Vault Server.

H.3 Ports for Services Provided by Database Firewall

Learn about the ports for services that are provided by Database Firewall.

Table H-2 lists ports for general services provided by Database Firewall. These services are used by outside users of the system, and access to all them can be controlled within Oracle Audit Vault and Database Firewall. If you use external network firewalls, then these ports must be open to enable connections from the users, or clients, of these services to the Database Firewall configurations in Oracle Audit Vault and Database Firewall.

Audit Vault and Database Firewall Internal Protocol

Incoming traffic captured from Host Monitor Agent. The Host Monitor Agent forwards the data securely to Database Firewall.

This applies when deployed in Host Monitor mode and ports need not be open during out-of-band or proxy mode.

For each monitoring point, a unique port is created in the given range. The exact port for each monitoring point can be found at /usr/local/dbfw/va/XX/etc/appliance.conf where XX represents the monitoring points created and have the value of 1, 2, 3…..N.

REMOTE_AGENT_LISTEN_PORT is the key in appliance.conf file that represents the port Database Firewall is listening for data from Host Monitor Agent.

The exact port number used by a monitoring point can be found in the Advanced settings.

H.4 Ports for External Network Access by Audit Vault Server

You must configure the correct external network firewall ports to enable Audit Vault Server to access them as a client.

Table H-3 lists ports for external services that Audit Vault Server can use. If you use external network firewalls, then the correct ports must be open so that Audit Vault Server can use these services as a client.
