12 Using Oracle Database Firewall with ArcSight SIEM

This appendix contains:

About the Integration of Oracle Database Firewall with ArcSight SIEM

The ArcSight Security Information Event Management (SIEM) system is a centralized system for logging, analyzing, and managing syslog messages from different sources. ArcSight SIEM enables Oracle Database Firewall to provide full details of any security alerts or other selected event types, including the message text, priority and IP address of any attacker. If you are using a Management Server, then it sends the ArcSight SIEM messages.

If you are also using the BIG-IP ASM interface, and an attack originates from the internet, Database Firewall provides the actual IP address of the attacking Web client. This feature enables you to pinpoint the source of the internet-based attack.

You do not need to install additional software if you want to integrate ArcSight SIEM with Database Firewall. You can configure the integration by using the Database Firewall Administration Console, which is described in the next section.

The syslog messages sent to the ArcSight SIEM Server are independent of any other syslog messages that may sent from Database Firewall. This means you can send standard syslog messages to a different destination.

Enabling the Oracle Database Firewall-ArcSight SIEM Integration

When you enable the Oracle Database Firewall and ArcSight SIEM integration, the settings take effect immediately. You do not need to restart Database Firewall.

To enable ArcSight SIEM for Oracle Database Firewall:

  1. Log in to the Administration Console for the standalone Database Firewall or the Management Server.

    See "Logging in to the Administration Console" for more information.

  2. Select the System tab.

  3. In the Connectors menu, select ArcSight SIEM.

    The ArcSight SIEM page appears.

  4. Specify the following options:

    • Enable ArcSight event forwarding: Select this check box to enable the ArcSight interface.

    • ArcSight destinations: Depending on the communications protocol you are using, enter the IP address or host name of the ArcSight server in the UDP or TCP field. This setting enables the syslog log output to be sent to this ArcSight server in Common Event Format (CEF).

    • Event categories: Select any combination of syslog categories depending on which type of messages that are needed in the ArcSight server. For detailed information about the message types, see "Oracle Database Firewall-ArcSight SIEM Syslog Mapping Tables".

    • Limit message length: To avoid sending large amounts of SQL text across the network, you can choose to limit the message to a specified number of characters.

    • Maximum message length (bytes): Enter the maximum length that you want. The range allowed is 1024 to 1048576 characters. The default is 256 bytes.

  5. Click the Apply button.

Oracle Database Firewall-ArcSight SIEM Syslog Mapping Tables

This section contains:

About the ArcSight SIEM Integration

You can send the ArcSight SEIM syslog output, as described in Oracle Database Firewall Security Management Guide. The following tables describe which messages are passed to ArcSight SIEM and the fields of the Oracle Database Firewall messages map to the relevant ArcSight keys.

Table 12-1 describes the message types that Oracle Database Firewall sends to ArcSight SIEM.

Table 12-1 Message Types Sent to ArcSight SIEM

Message Type Event Name Description

DBFW:3

Heartbeat

Heartbeat messages. One message is generated every second while Database Firewall is running.

DBFW:4

Property change

Property change message. Describes configuration changes that are made by users.

DBFW:8

Database audit

Database Object Auditing messages. These are generated by the Stored Procedure Auditing or User Role Auditing functionality of the Database Firewall.

DBFW:9

Statement alert

Statement alerts. An alert of this type is given to display a full SQL statement and associated details. If database response monitoring is enabled, the response information is included in the alert.

DBFW:10

Statement alert (WAF)

Statement Web Application Firewall (WAF) alerts. An alert of this type is given when the Database Firewall appliance is working together with a Web Application Firewall. If database response monitoring is enabled, the response information is included in the alert.

DBFW:11

Login alert

A user has attempted to log in to the database. If database response monitoring is enabled, the result of the login attempt (success or failure) is included in the alert.

DBFW:12

Logout alert

A user has explicitly logged out from the database, or their TCP session has been closed.

DBFW:system

System messages

System messages in operating system format. These are alerts generated by the underlying operating system on which Database Firewall is installed.


DBFW:3 (Heartbeat)

DBFW:3 heartbeat messages are generated every second while Database Firewall is running. The heartbeat message contains statement counts.
