Managing Sensor Devices Guide

1MANAGING SENSOR DEVICES

You can configure STRM Log Management to log and correlate events received

from external sources such as security equipment (for example, firewalls and

IDSs) and network equipment (for example, switches and routers). Sensor devices

allow you to integrate STRM Log Management with these external devices. This

chapter provides information on configuring sensor devices to the system

including:

•Configuring STRM Log Management to Receive Events

•Managing Sensor Devices

•Configuring Protocols

•Grouping Sensor Devices

Configuring STRM

Log Management to

Receive Events

STRM Log Management allows you to automatically discover sensor devices in

your deployment that are sending syslog messages. Any sensor devices that are

automatically discovered by STRM Log Management appear in the Sensor

Devices window. Automatic discovery of sensor devices can be configured on a

per Event Collector basis using the Auto Detection Enabled parameter in the Event

Collector configuration. For more information, see the STRM Log Management

Administration Guide, Using the Deployment Editor.

To configure STRM Log Management to receive events from devices, you must:

Step 1 Configure the device to send events to STRM Log Management.

For information on configuring DSMs, see the Configuring DSMs Guide and your

vendor documentation.

Step 2 Configure STRM Log Management to receive events from specific devices. See

Managing Sensor Devices.

Note: You must have administrative privileges to configure sensor devices in

STRM Log Management. For more information on accessing the Administration

Console, see the STRM Log Management Administration Guide.

Step 3 Configure the necessary protocols. See Configuring Protocols.

Managing Sensor

Devices

A sensor device provides events to your deployment through DSMs. Using the

Administration Console, you can:

•Add a sensor device. See Adding a Sensor Device.

•Edit an existing sensor device. See Editing Sensor Devices.

•Enable or disable a sensor device. See Enabling/Disabling Sensor Devices.

•Delete a sensor device. See Deleting a Sensor Device.

Adding a Sensor

Device

To add a sensor device to your deployment:

Step 1 In the Administration Console, click the SIM Configuration tab.

The SIM Configuration panel appears.

Step 2 Click the Sensor Devices icon.

The Sensor Devices window appears.

Step 3 Click Add.

The Add a sensor device window appears.

Step 4 Enter values for the parameters:

Managing Sensor Devices Guide

Managing Sensor Devices 5

Table 1-1 Add a Sensor Device Parameters

Parameter Description

Device Name Specify the desired name of the device.

Sensor Device Type Using the drop-down list, select the type of sensor

device you wish to add.

Protocol Configuration Using the drop-down list box, select the protocol you

wish to use for this sensor device. If the device uses

syslog, a default syslog configuration is automatically

applied. For more information on configuring protocols,

see Adding a Protocol.

Device Description Specify a description for the sensor device (optional).

Device Hostname/IP Specify the hostname or IP address for the device. If

you wish to add the device using the hostname, please

note that you must enter the hostname as it exactly

appears in the logs sent to STRM Log Management.

Otherwise, STRM Log Management will not process

the events.

Credibility Specify the credibility of the device. The range is from 0

to 10. The credibility indicates the integrity of an event

or offense as determined by the credibility rating from

source devices. Credibility increases if multiple sources

report the same event. The default is 5.

Target Event Collector Using the drop-down list box, select the Event Collector

you wish to use as the target for this device.

Coalescing Events Enables or disables the ability of a sensor device to

coalesce (bundle) events. The default is Yes.

By default, all auto detected sensor devices use the

value configured in the Coalescing Events parameter in

the STRM Settings window. However, when you create

a new sensor device or update the configuration for an

auto detected sensor device, the value configured in

the individual sensor device is the value used by the

sensor device. For more information, see the STRM

Log Management Administration Guide.

Store Event Payload Enables or disables the ability for a sensor device to

store event payload information. The default is Yes.

By default, all auto detected sensor devices use the

value configured in the Store Event Payload parameter

in the STRM Settings window. However, when you

create a new sensor device or update the configuration

for an auto detected sensor device, the value

configured in the individual sensor device is the value

used by the sensor device. For more information, see

the STRM Log Management Administration Guide.

Step 5 Click Save.

The Sensor Devices window appears.

Editing Sensor

Devices

To edit a sensor device:

Step 1 In the Administration Console, click the SIM Configuration tab.

The SIM Configuration panel appears.

Step 2 Click the Sensor Devices icon.

The Sensor Devices window appears.

Step 3 Select the sensor device you wish to edit.

Step 4 Click Edit.

The Edit a sensor device window appears.

Device Extension Using the drop-down list box, select the device

extension you wish to use for this sensor device.

Device extensions allow you to immediately extend the

parsing routines of specific devices, which ensures

DSMs send valid data to STRM.

For more information on device extensions, see

Creating a Device Extension.

Extension Use Condition Using the drop-down list box, select the extension use

condition that you wish to use for this sensor device:

•Parsing Enhancement - When the DSM is unable

to parse correctly or is unable to retrieve specific

information from the DSM, the selected device

extension overrides the failed parsing by the DSM.

This is the default setting.

•Parsing Override - When the DSM parses correctly

for most fields, but needs either one or two fields

corrected, the incorrectly parsed field values are

enhanced.

Groups Select any groups of which you wish this sensor device

to be a member.
