STRM Installation Guide
1PREPARING FOR YOUR
INSTALLATION
This chapter provides information for when planning your STRM deployment
including:
•Deploying STRM
•Additional Hardware Requirements
•Additional Software Requirements
•Browser Support
•Preparing Your Network Hierarchy
•Identifying Network Settings
•Identifying Security Monitoring Devices and Flow Data Sources
•Identifying Network Assets
Your STRM deployment may consist of STRM installed on one or multiple
systems. You can use the STRM three-tier architecture to install any or all
components on a single server for small enterprises or distributed across multiple
servers for maximum performance and scalability in large enterprise
environments.
To ensure a successful STRM deployment, adhere to the recommendations in this
document.

STRM Installation Guide
6PREPARING FOR YOUR INSTALLATION
Deploying STRM You can deploy STRM using STRM appliances or STRM software installed on your
own hardware. This section provides information on deploying STRM including:
•STRM Components
A STRM appliance includes STRM software and a CentOS-4 operating system.
For further information on STRM appliances, see the Hardware Installation Guide.
STRM Components STRM components that may exist in your deployment include:
Note: For more information on each STRM component, see the STRM
Administration Guide.
•Flow Collector - Passively collects traffic flows from your network through span
ports or network taps. The Flow Collector also supports the collection of
external flow-based data sources, such as NetFlow. You can install a Flow
Collector on your own hardware or use one of the QFlow appliances.
•Flow Processor - Normalizes flows sent from one or more Flow Collector(s) by
consolidating, aggregating, and removing duplicate flows. The Flow Collector
can also create superflows (aggregate flows) before the flows reach the
Classification Engine.
•Classification Engine - Analyzes flows to classify and identify all traffic in the
enterprise network into multiple objects.
•Console - Provides the interface for STRM. The Console provides real time
views, reports, alerts, and in-depth flow views of network traffic and security
threats. This Console is also used to manage distributed STRM deployments.
The Console is accessed from a standard web browser. When you access the
system, a prompt appears for a user name and password, which must be
configured during the installation process. You must also have Java installed.
For information on software requirements, see Additional Software
Requirements.
•Update Daemon - Stores the database and TopN data. Typically, the Update
Daemon is installed on the Console.
•Flow Writer - Stores the flow and asset profile data.
•Offense Resolution - Offense Resolution is a module that provides
enterprise-wide intrusion prevention for your network and includes Resolvers,
Resolutions and Resolver Agents.
•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. During
this process, Magistrate risk factors map the events to the STRM Identification
System, and creates the bundles.
•Event Processor - Processes events collected from one or more Event
Collector(s). Once received, the Event Processor correlates the information

STRM Installation Guide
Additional Hardware Requirements 7
from STRM and distributes to the appropriate area, depending on the type of
event. The Event Processor also includes information gathered by STRM to
indicate any behavioral changes or policy violations for the event. Rules are
applied to the events that allow the Event Processor to process according to the
configured rules. Once complete, the Event Processor sends the events to the
Magistrate.
•Magistrate - Provides the core processing components. You can add one
Magistrate component for each deployment. The Magistrate provides views,
reports, alerts, and analysis of network traffic and security events. The
Magistrate processes the event against the defined custom rules to create an
offense. If no custom rules exist, the Magistrate uses the default rules to
process the event. An offense is an event that has been processed through
STRM using multiple inputs, individual events, and events combined with
analyzed behavior and vulnerabilities. Magistrate prioritizes the offenses and
assigns a magnitude value based on several factors, including number of
events, severity, relevance, and credibility.
Additional
Hardware
Requirements
Before installing your STRM systems, make sure you have access to the additional
hardware components:
•Monitor and keyboard or a serial console
•To make sure that your STRM data is preserved during a power failure, we
highly recommend that all STRM appliances or systems running STRM
software storing data (such as, Consoles, Event Processors, or Flow
Processors) be equipped with a Uninterrupted Power Supply (UPS).
AdditionalSoftware
Requirements Before installing STRM, make sure you have Java Runtime Environment installed
on your system. You can download Java version 1.5.0_12 at the following web
site: http://java.com/.
Browser Support You must have a browser installed on your client system to access the STRM
interface. STRM supports the following web browsers:
- Microsoft Internet Explorer 6.0/7.0
- Firefox 2.0
Preparing Your
Network Hierarchy STRM uses the network hierarchy to understand your network traffic and provide
you with the ability to view network activity for your entire deployment. STRM
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.

STRM Installation Guide
8PREPARING FOR YOUR INSTALLATION
Once you define the components you wish to add to your network hierarchy and
install STRM, you can then configure the network hierarchy using the STRM
interface. For each component you wish to add to your network hierarchy, use the
following table to indicate each component in your network map.
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 Administration Guide - Setting Up STRM,
Creating Your Network Hierarchy.
Identifying Network
Settings Before you install STRM, 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

STRM Installation Guide
Identifying Security Monitoring Devices and Flow Data Sources 9
Identifying Security
Monitoring Devices
and Flow Data
Sources
STRM 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) and Flow
Collectors allows you to integrate STRM with this external data.
STRM automatically discovers sensor devices that are sending syslog messages
to an Event Collector. Any sensor devices that are automatically discovered by
STRM appear in the Sensor Devices window within the STRM Administration
Console. Once auto discovery is complete, you should disable the Auto Detection
Enabled option in the Event Collector configuration. For more information, see
Chapter 4 Using the Deployment Editor of the STRM 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 Table 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 devices is located on the same LAN as
STRM or sending logs over the WAN identified in the Link Speed & Type
column.
•Credibility indicates the integrity of an event or offense as determined by the
credibility rating from source devices. Credibility increases as the multiple
sources report the same event.

Identifying Network
Assets STRM can learn about your network and server infrastructure based on flow data.
The Server Discovery function uses STRM’s Asset Profile database to discover
many types of servers.
Defining certain additional server and IP address types also improves tuning
results. Table 1-3 provides a list of possible servers. When identified, see the
STRM Users Guide for information on defining severs within STRM. If your
network includes a large number of servers, you can use CIDR or IP subnet
addresses within the server networks category.
