What Is the ProSecure Unified Threat Management (UTM)

Appliance?

The ProSecure Unified Threat Management (UTM) Appliance, hereafter referred to as the

UTM, connects your local area network (LAN) to the Internet through one or two external

broadband access devices such as cable modems, DSL modems, satellite dishes, or

wireless ISP radio antennas, or a combination of those. Dual wide area network (WAN) ports

allow you to increase the effective data rate to the Internet by utilizing both WAN ports to

carry session traffic, or to maintain a backup connection in case of failure of your primary

Internet connection.

As a complete security solution, the UTM combines a powerful, flexible firewall with a content

scan engine that uses NETGEAR Stream Scanning technology to protect your network from

denial of service (DoS) attacks, unwanted traffic, traffic with objectionable content, spam,

phishing, and web-borne threats such as spyware, viruses, and other malware threats.

Introduction

Multiple WAN Port Models for Increased Reliability or

Outbound Load Balancing

The UTM product line offers models with two broadband WAN ports. The second WAN port

allows you to connect a second broadband Internet line that can be configured on a mutually

exclusive basis to:

• Provide backup and rollover if one line is inoperable, ensuring that you are never

disconnected.

• Load balance, or use both Internet lines simultaneously for outgoing traffic. A UTM with

dual WAN ports balances users between the two lines for maximum bandwidth efficiency.

See Appendix C, Network Planning for Dual WAN Ports (Multiple WAN Port Models Only) for

the planning factors to consider when implementing the following capabilities with dual WAN

port gateways:

• Single or multiple exposed hosts

• Virtual private networks

Wireless Features

Wireless client connections are supported on the UTM9S with a UTM9SWLSN wireless

module installed. The UTM9S supports the following wireless features:

• 2.4-GHz radio and 5-GHz radio. Either 2.4-GHz band support with 802.11b/g/n/ wireless

modes or 5-GHz band support with 802.11a/n wireless modes.

• WMM QoS priority. Wi-Fi Multimedia (WMM) Quality of Service (QoS) priority settings to

map one of four queues to each Differentiated Services Code Point (DSCP) value.

• Wireless Distribution System (WDS). WDS enables expansion of a wireless network

through two or more access points that are interconnected.

Advanced VPN Support for Both IPSec and SSL

The UTM supports IPSec and SSL virtual private network (VPN) connections.

• IPSec VPN delivers full network access between a central office and branch offices, or

between a central office and telecommuters. Remote access by telecommuters requires

the installation of VPN client software on the remote computer.

-IPSec VPN with broad protocol support for secure connection to other IPSec

gateways and clients.

-Depending on the model, bundled with a one-user license of the NETGEAR ProSafe

VPN Client software (VPN01L).

• SSL VPN provides remote access for mobile users to selected corporate resources

without requiring a preinstalled VPN client on their computers.

-Uses the familiar Secure Sockets Layer (SSL) protocol, commonly used for

e-commerce transactions, to provide client-free access with customizable user portals

and support for a wide variety of user repositories.

-Allows browser-based, platform-independent remote access through a number of

popular browsers, such as Microsoft Internet Explorer, Mozilla Firefox, and Apple

Safari.

-Provides granular access to corporate resources based on user type or group

membership.

A Powerful, True Firewall

Unlike simple NAT routers, the UTM is a true firewall, using Stateful Packet Inspection (SPI)

to defend against hacker attacks. Its firewall features have the following capabilities:

• DoS protection. Automatically detects and thwarts denial of service (DoS) attacks such

as Ping of Death and SYN flood.

• Secure firewall. Blocks unwanted traffic from the Internet to your LAN.

• Schedule policies. Permits scheduling of firewall policies by day and time.

• Logs security incidents. Logs security events such as blocked incoming traffic, port

scans, attacks, and administrator logins. You can configure the firewall to email the log to

you at specified intervals. You can also configure the firewall to send immediate alert

messages to your email address or email pager whenever a significant event occurs.

Stream Scanning for Content Filtering

Stream Scanning is based on the simple observation that network traffic travels in streams.

The UTM scan engine starts receiving and analyzing traffic as the stream enters the network.

As soon as a number of bytes are available, scanning starts. The scan engine continues to

scan more bytes as they become available, while at the same time another thread starts to

deliver the bytes that have been scanned.

Introduction

ProSecure Unified Threat Management (UTM) Appliance

This multithreaded approach, in which the receiving, scanning, and delivering processes

occur concurrently, ensures that network performance remains unimpeded. The result is that

file scanning is up to five times faster than with traditional antivirus solutions—a performance

advantage that you will notice.

Stream Scanning also enables organizations to withstand massive spikes in traffic, as in the

event of a malware outbreak. The scan engine has the following capabilities:

• Real-time protection. The patent-pending Stream Scanning technology enables

scanning of previously undefended real-time protocols, such as HTTP. Network activities

susceptible to latency (for example, web browsing) are no longer brought to a standstill.

• Comprehensive protection. Provides both web and email security, covering six major

network protocols: HTTP, HTTPS, FTP, SMTP, POP3, and IMAP. The UTM uses

enterprise-class scan engines employing both signature-based and distributed spam

analysis to stop both known and unknown threats. The malware database contains

hundreds of thousands of signatures of spyware, viruses, and other malware.

• Objectionable traffic protection. The UTM prevents objectionable content from

reaching your computers. You can control access to the Internet content by screening for

web services, web addresses, and keywords within web addresses. You can log and

report attempts to access objectionable Internet sites.

• Automatic signature updates. Malware signatures are updated as frequently as every

hour, and the UTM can check automatically for new signatures as frequently as every 15

minutes.

Security Features

The UTM is equipped with several features designed to maintain security:

• PCs hidden by NAT. NAT opens a temporary path to the Internet for requests originating

from the local network. Requests originating from outside the LAN are discarded,

preventing users outside the LAN from finding and directly accessing the computers on

the LAN.

• Port forwarding with NAT. Although NAT prevents Internet locations from directly

accessing the PCs on the LAN, the UTM allows you to direct incoming traffic to specific

PCs based on the service port number of the incoming request. You can specify

forwarding of single ports or ranges of ports.

• DMZ port. Incoming traffic from the Internet is usually discarded by the UTM unless the

traffic is a response to one of your local computers or a service for which you have

configured an inbound rule. Instead of discarding this traffic, you can use the dedicated

demilitarized zone (DMZ) port to forward the traffic to one PC on your network.

Autosensing Ethernet Connections with Auto Uplink

With its internal four- or six-port 10/100/1000 Mbps switch and single or dual

(model-dependant) 10/100/1000 WAN ports, the UTM can connect to either a 10 Mbps

standard Ethernet network, a 100 Mbps Fast Ethernet network, or a 1000 Mbps Gigabit

Introduction

ProSecure Unified Threat Management (UTM) Appliance

Ethernet network. The four LAN and one or two WAN interfaces are autosensing and capable

of full-duplex or half-duplex operation.

The UTM incorporates Auto UplinkTM technology. Each Ethernet port automatically senses

whether the Ethernet cable plugged into the port should have a normal connection such as to

a PC or an uplink connection such as to a switch or hub. That port then configures itself

correctly. This feature eliminates the need for you to think about crossover cables, as Auto

Uplink accommodates either type of cable to make the right connection.

Extensive Protocol Support

The UTM supports the Transmission Control Protocol/Internet Protocol (TCP/IP) and Routing

Information Protocol (RIP). For further information about TCP/IP, see Internet Configuration

Requirements on page 558. The UTM provides the following protocol support:

• IP address sharing by NAT. The UTM allows many networked PCs to share an Internet

account using only a single IP address, which might be statically or dynamically assigned

by your Internet service provider (ISP). This technique, known as Network Address

Translation (NAT), allows the use of an inexpensive single-user ISP account.

• Automatic configuration of attached PCs by DHCP. The UTM dynamically assigns

network configuration information, including IP, gateway, and Domain Name Server

(DNS) addresses, to attached PCs on the LAN using the Dynamic Host Configuration

Protocol (DHCP). This feature greatly simplifies configuration of PCs on your local

network.

• DNS proxy. When DHCP is enabled and no DNS addresses are specified, the firewall

provides its own address as a DNS server to the attached PCs. The firewall obtains

actual DNS addresses from the ISP during connection setup and forwards DNS requests

from the LAN.

• PPP over Ethernet (PPPoE). PPPoE is a protocol for connecting remote hosts to the

Internet over a DSL connection by simulating a dial-up connection.

• Quality of Service (QoS). The UTM supports QoS, including traffic prioritization and

traffic classification with Type of Service (ToS) and Differentiated Services Code Point

(DSCP) marking.

Easy Installation and Management

You can install, configure, and operate the UTM within minutes after connecting it to the

network. The following features simplify installation and management tasks:

• Browser-based management. Browser-based configuration allows you to easily

configure the UTM from almost any type of operating system, such as Windows,

Macintosh, or Linux. A user-friendly Setup Wizard is provided, and online help

documentation is built into the browser-based web management interface.

• Autodetection of ISP. The UTM automatically senses the type of Internet connection,

asking you only for the information required for your type of ISP account.
