STRM-LM Installation Guide

1PREPARING FOR YOUR

INSTALLATION

This chapter provides information for when planning your STRM-LM deployment

including:

•Deploying STRM-LM

•Additional Hardware Requirements

•Additional Software Requirements

•Browser Support

•Preparing Your Network Hierarchy

•Identifying Network Settings

•Identifying Security Monitoring Devices

Your STRM-LM deployment may consist of STRM-LM installed on one or multiple

systems. You can also connect one or multiple STRM 1601system to your

STRM-LM system. For more information on appliances, see the Hardware

Installation Guide.

To ensure a successful STRM-LM deployment, adhere to the recommendations in

this document.

Deploying

STRM-LM

You can deploy STRM-LM using appliances or STRM-LM software installed on

your own hardware. A STRM-LM appliance includes STRM-LM software and a

CentOS-4 operating system. For further information on STRM appliances, see the

Hardware Installation Guide.

STRM-LM components that may exist in your deployment include:

Note: For more information on each STRM-LM component, see the STRM-LM

Administration Guide.

•Console - Provides the interface for STRM-LM. The Console is accessed from

a standard web browser. When you access the system, a prompt appears for a

user name and password, which is configured during the installation process.

You must also have Java installed. For information on software requirements,

see Additional Software Requirements.

STRM-LM Installation Guide

4PREPARING FOR YOUR INSTALLATION

•Event Collector - The Event Collector gathers events from local and remote

device sources. The Event Collector normalizes events and sends the

information to the Event Processor. Before being sent to the Event Processor,

the Event Collector bundles identical events to conserve system usage.

•Event Processor - Processes events collected from one or more Event

Collector(s). Once received, the Event Processor correlates the information

from STRM-LM and distributes to the appropriate area, depending on the type

of event. Rules are applied to the events that allow the Event Processor to

process according to the configured rules.

Additional

Hardware

Requirements

Before installing your STRM-LM systems, make sure you have access to the

additional hardware components:

•Monitor and keyboard or a serial console

•To make sure that your STRM-LM data is preserved during a power failure, we

highly recommend that all STRM-LM appliances or systems running STRM-LM

software storing data (such as, Consoles or Event Processors) be equipped

with a Uninterrupted Power Supply (UPS).

Additional Software

Requirements

Before installing STRM-LM, make sure you have Java Runtime Environment

installed on your system. You can download Java version 1.5.0_15 at the following

web site: http://java.com/

Browser Support You must have a browser installed on your client system to access the STRM-LM

interface. STRM-LM supports the following web browsers:

- Microsoft Internet Explorer 6.0/7.0

- Firefox 2.0

Preparing Your

Network Hierarchy

STRM-LM uses the network hierarchy to understand your network traffic and

provide you with the ability to view network activity for your entire deployment.

STRM-LM supports any network hierarchy that can be defined by a range of IP

addresses. You can create your network based on many different variables,

including geographical or business units. For example, your network hierarchy

may include corporate IP address ranges (internal or external), physical

departments or areas, mails servers, and web servers.

Once you define the components you wish to add to your network hierarchy and

install STRM-LM, you can then configure the network hierarchy using the

STRM-LM interface. For each component you wish to add to your network

hierarchy, use the following table to indicate each component in your network map.

STRM-LM Installation Guide

Identifying Network Settings 5

At a minimum, we recommend that you define objects in the network hierarchy for:

•Internal/external Demilitarized zone (DMZ)

•VPN

•All internal IP address space (for example, 0.0.0.0/8)

•Proxy servers

•Network Address Translation (NAT) IP address range

•Server Network subnets

•Voice over IP (VoIP) subnets

For more information, see the STRM-LM Administration Guide - Setting Up

STRM-LM, Creating Your Network Hierarchy.

Identifying Network

Settings

Before you install STRM-LM, you must have the following information for each

system you wish to install:

•Hostname

•IP address

•Network Mask address

•Subnet Mask

•Default Gateway

•Primary DNS Server

•Secondary DNS Server (Optional)

•Public IP address for networks using Network Address Translation (NAT)

•E-mail Server

•NTP Server (Console only) or Time server

Identifying Security

Monitoring Devices

STRM-LM can collect and correlate events received from external sources such as

security equipment (for example, firewalls, VPNs, or IDSs) and host or application

security logs, such as, window logs. Device Support Modules (DSMs) allows you

to integrate STRM-LM with this external data.

STRM-LM Installation Guide

6PREPARING FOR YOUR INSTALLATION

STRM-LM automatically discovers sensor devices that are sending syslog

messages to an Event Collector. Any sensor devices that are automatically

discovered by STRM-LM appear in the Sensor Devices window within the

STRM-LM Administration Console. For more information, see Chapter 4 Using the

Deployment Editor of the STRM-LM Administration Guide.

Non-syslog based information sources must be added to your deployment

manually. For more information, see the Managing Sensor Devices Guide. For

each device you wish to add to your deployment, record the device in Ta b l e 1 - 2 .

Where:

•Link Speed & Type indicates the maximum network link (in Kbps) for firewall,

router, and VPN devices. Record the primary application of the host system, for

example, e-mail, anit-virus, domain controller, or a workstation.

•Msg Level indicates the message level you wish to log. For example, critical,

informational, debug.

•No. of Users indicates the maximum number of hosts/users using or being

served by tis device.

•Network Location indicates whether this device is located on the Internet

DMZ, Intranet, or Extranet DMZ.

•Geographic Location indicates if the device is located on the same LAN as

STRM-LM or sending logs over the WAN identified in the Link Speed & Type

column.

•Credibility indicates the integrity of an event as determined by the credibility

rating from source devices. Credibility increases as multiple sources report the

same event.
