29 CHAPTER 3 Planning StoneGate IPS Installation This chapter provides general information about the installation, hardware and software prerequisites, and other important information to take into account before the actual StoneGate IPS installation can be performed. This chapter includes the following sections: Important to Know Before Installation, on page 30 System Components and Supported Platforms, on page 30 Checking the Surrounding Network Environment, on page 31 System Installation, on page 32 Overview to the Installation Procedure, on page 37. StoneGate IPS Installation Guide 29

30 Chapter 3: Planning StoneGate IPS Installation Important to Know Before Installation 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. System Components and Supported Platforms 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 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. 30

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 For more information on MD5 and SHA-1 algorithms, please see RFC1321 and RFC3174, respectively. The RFCs can be obtained from 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 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 $ md5sum sg_engine_ iso 869aecd7dc39321aa2e0cfaf7fafdb8f sg_engine_ iso 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. Checking the Surrounding Network Environment StoneGate IPS can be connected to a switch SPAN port, a network TAP, or a hub to capture network traffic. The considerations for these connection methods are explained below. For more specific information on compatibility of different network devices and StoneGate IPS, please refer to the Stonesoft Web site at support/. StoneGate IPS Installation Guide 31

32 Chapter 3: Planning StoneGate IPS Installation 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. System Installation 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

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. Example Network Scenario Three example Sensor installations are described in this Guide: a combined Sensor/Analyzer a single Sensor a Sensor cluster installation. The two different Analyzer installations are illustrated with a combined Sensor/Analyzer an Analyzer on a separate machine. The network scenario for these installations is based on the example network in Figure 3.1. The scenario illustration can also be found in the front of the book. StoneGate IPS Installation Guide 33
