I m p o r t a n t t o K n o w B e f o r e I n s t a l l a t i o n

Before you start the installation, you need to plan carefully the site that you are going to

install. Check that your operating system and hardware are supported and familiarize

yourself with the surrounding network components. Please, see the StoneGate IPS Release

Notes for further information. When planning StoneGate IPS installation, please see the

StoneGate IPS Administrator’s Reference for detailed information on the operation of

StoneGate IPS.

P la t f o r m s

StoneGate IPS System Components

A StoneGate IPS system consists of the Management Center, one or more Sensors, and

an Analyzer. The StoneGate Management Center consists of the following components:

• the Management Server

• one or more Log Servers

• one or more graphical user interface (GUI) clients.

The StoneGate IPS Sensors and Analyzers can be distributed as follows:

• a combined Sensor/Analyzer with these two components on a single machine.

• a single node Sensor.

• a Sensor cluster which consists of 2 to 16 machines with Sensors called cluster nodes or

nodes for short.

• an Analyzer which is required for the Sensors. An Analyzer located on a combined

Sensor/Analyzer can also be used by other Sensors.

Supported Platforms

For detailed information on the supported platforms, please see the StoneGate IPS

Hardware Requirements available at

http://www.stonesoft.com/

.

The Sensors and Analyzers have an integrated, hardened Linux operating system and

therefore they require no separate operating system installation. The integrated operating

system simplifies upgrading the Sensors and Analyzers significantly, as they can be

upgraded as a whole without having to separately upgrade the operating system and the

StoneGate IPS software.

(31)

Checking the Surrounding Network Environment

Checking the File Integrity

Before installing StoneGate IPS, check the installation file integrity using the MD5 or

SHA-1 file checksums. The checksums can be found on the StoneGate IPS installation

CD-ROM and from the product-specific download page at the Stonesoft Web site at

http://www.stonesoft.com/download/

. For more information on MD5 and SHA-1

algorithms, please see RFC1321 and RFC3174, respectively. The RFCs can be obtained

from

http://www.rfc-editor.org/

.

Windows does not have MD5 or SHA-1 checksum tools by default, but there are several

third-party programs available.

▼ To check MD5 or SHA-1 file checksum

1. Obtain the checksum from Stonesoft Web site at

http://www.stonesoft.com/

download/

.

2. Change to the directory that contains the file(s) to be checked.

3. Generate a checksum of the file using the command

md5sum filename

or

sha1sum filename

, where

filename

is the name of the installation file.

ILLUSTRATION 3.1 Checking the File Checksums

4. Compare the displayed output to the checksum on the Web site.

Caution – Do not use files that have invalid checksums. Contact Stonesoft technical

support to resolve the issue.

Switch SPAN Ports and Hubs

A Switched Port Analyzer (SPAN) port is used for capturing network traffic to a defined

port on a switch. This is also known as port mirroring. The capturing is done passively, so

it does not interfere with the traffic. With a hub, no special configuration such as a SPAN

port is needed as all the traffic going through the hub is directed to all ports.

A StoneGate IPS capturing interface can be connected directly to a SPAN port of a

switch. Then, all the traffic to be monitored need to be copied to this SPAN port. The

SPAN mode capturing interface is also used when connecting the capture interface to a

hub, although using a hub might not be suitable because of network performance

reasons.

Network TAPs

A Test Access Port (TAP) is a passive device located at the network wire between network

devices. The capturing is done passively, so it does not interfere with the traffic. With a

network TAP, the two directions of the network traffic is divided to separate wires. For

this reason, StoneGate IPS needs two capturing interfaces for a network TAP; one

capture interface for each direction of the traffic. The two related capturing interfaces are

handled in StoneGate IPS as one logical interface that combines the traffic of these two

interfaces for inspection.

The StoneGate IPS system consists of the Management Center, the Sensors, and the

Analyzers. The StoneGate Management Center (SMC) components can be installed

separately on different machines or on the same machine, depending on your

requirements. The Management Center can manage one or more StoneGate IPS Sensors

and Analyzers. The same SMC can also be used for managing StoneGate firewall and

VPN solutions.

The StoneGate IPS Analyzer can be either installed on a separate machine, or combined

with a Sensor on a single machine as a combined Sensor/Analyzer. The combined Sensor/

Analyzer is mainly aimed for small environments, whereas the separate Analyzer

machine should be used where higher performance is required.

The three basic types of StoneGate IPS Sensor installations are as follows:

• Single Sensor installation. A single Sensor has only one node. It does not support load

balancing or high availability. Instructions on defining a single Sensor element is

covered in

Defining a Single Sensor

, on page 73.

(33)

System Installation

• Sensor cluster installation. A StoneGate IPS Sensor cluster supports up to 16 nodes

functioning as a single virtual entity. Each node of the cluster uses the same security

policy configuration defined through the GUI client. A cluster can be configured for

dynamic load balancing or as a hot standby solution. Instructions on defining a Sensor

cluster element is covered in

Defining a Sensor Cluster

, on page 67.

• Combined Sensor/Analyzer installation. A combined Sensor/Analyzer is similar to

Single Sensor but it also has the Analyzer on the same physical machine. This

installation does not support load balancing or high availability. Instructions on

defining a combined Sensor/Analyzer element is covered in

Defining a Combined

Sensor/Analyzer

, on page 77.

For more information, please see the StoneGate IPS Administrator’s Reference and the

StoneGate IPS Administrator’s Guide.
