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
4PREPARING 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.
•QFlow Collector - Passively collects traffic flows from your network through
span ports or network taps. The QFlow Collector also supports the collection of
external flow-based data sources, such as NetFlow. You can install a QFlow
Collector on your own hardware or use one of the QFlow appliances.
•Flow Processor - Normalizes flows sent from one or more QFlow Collector(s)
by consolidating, aggregating, and removing duplicate flows. The QFlow
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.

STRM Installation Guide
Additional Hardware Requirements 5
•Event Processor - Processes events collected from one or more Event
Collector(s). Once received, the Event Processor correlates the information
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).
Additional Software
Requirements
Before installing STRM, 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
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.

STRM Installation Guide
6PREPARING FOR YOUR INSTALLATION
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, 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)
