NetDefend Firewall UTM Services
Unified Threat Management
D-Link NetDefend UTM firewalls integrate an Intrusion Prevention System (IPS), gateway AntiVirus (AV),
and Web Content Filtering (WCF) for superior Layer 7 content inspection protection. An acceleration engine
increases throughput, while the real-time update service keeps the IPS information, antivirus signatures, and
URL databases current. Combined, these enhancements help to protect office networks from application
exploits, network worms, malicious code attacks, and provide everything a business needs to safely manage
employee Internet access. Maintaining an effective defense against the various threats originating from the
Internet requires that all three databases used by the UTM firewall are kept up-to-date. In order to provide
a robust defense, D-Link offers NetDefend Firewall UTM Services which include distinct NetDefend service
updates for each aspect of your defenses: IPS, AntiVirus, and WCF. NetDefend Firewall UTM Services ensure
that each of your UTM firewall’s service databases is always accurate and current.

NetDefend Intrusion Prevention System (IPS)
D-Link’s IPS service adopts a unique technology – component-based signatures, which are built to recognize
and protect against all varieties of known and unknown attacks, and which address all critical aspects of an
attack or potential attack including payload, NOP sled, infection, and exploits.
In terms of signature coverage, the IPS database includes attack information and data from a global attack
sensor-grid and exploits collected from public sites such as the National Vulnerability Database and Bugtrax.
D-Link is committed to delivering high quality IPS signatures by constantly creating and optimizing NetDefend
signatures via the D-Link Auto-Signature Sensor System. Without overloading existing security appliances,
D-Link IPS signatures ensure a high ratio of detection accuracy and the lowest ratio of false positives.
My D-Link
My D-Link provides a registration and
management platform for all D-Link customers.
D-Link customers need to register their
firewall to receive IPS update service from
the NetDefend Center’s My D-Link. The
current status of all registered products will
be presented, including Model Names, MAC
addresses, Serial Numbers, Registration dates,
and IPS Service Expiration dates. Customers
can easily maintain all firewalls registered
under My D-Link.
NetDefend Live
The NetDefend Center includes a ‘NetDefend Live’ service for our customers. NetDefend Live is a platform for
providing information about potential security breaches and associated advisories. When D-Link Security Center
discovers new exploits and releases new signatures, associated security advisories will be simultaneously
updated. This update frequency is provided on a 24x7x365 basis. The main purpose of NetDefend Live is to help
our customers know more about new signatures and vulnerabilities. MIS departments can use NetDefend Live
as reference to uproot threats and patch vulnerabilities within the enterprise before they are exploited. With
NetDefend firewalls as the first line of defense and NetDefend Live as the second, D-Link helps customers to
counteract emerging network threats promptly, before they have an impact on business.

Features and Benefits
Focus on Attack Payload, not Attackers or IP Addresses
The IPS scan engine is an in-depth inspection of data from Layer 2 to Layer 7 protecting against both false
positives and false negatives and preventing various types of network-based threats with a high degree of
Zero Day Attack Protection
IPS captures variations of attacks and stealthy malicious
traffic to prevent outbreaks of these threats without
creating unnecessary new signatures while still
protecting against Zero-Day attacks.
Continuous Automatic Signature Updates
All IPS signatures are continuously updated automatically
and made available through D-Link update servers
worldwide. The service keeps your IPS signature
database as current as possible at the outside of new
Comprehensive IPS Signature Database
Protect the system against network attacks using over
17,000 signatures as well as protocol anomaly inspection.
Complete IPS Signature Advisory
Complete IPS logs with vulnerability ID numbers, severity levels, attack descriptions, and recovery solutions
enable MIS personnel to know about and respond quickly to network attacks.

NetDefend AntiVirus (AV) Subscription
NetDefend UTM firewalls implement stream-based virus scanning technology without first caching incoming
files, thus increasing inspection performance and easing network bottleneck nightmares while enabling
powerful virus defense capabilities.
D-Link’s firewalls use virus signatures from the known, respected antivirus company Kaspersky Labs to provide
our customers with prompt signature updates and reliable, accurate antivirus signatures.
Using a built-in extreme-performance AV acceleration engine together with stream-based virus scanning
technology, NetDefend UTM firewalls block viruses and malware before they ever reach your network’s
desktops or mobile devices. NetDefend firewalls create a safer network environment for companies of all
sizes, from SMBs to enterprises.
Features and Benefits
Up-to-date Protection
Kaspersky Labs is the market leader in AV signature creation, providing the fastest response to the most
dangerous viruses, Trojans, worms, and spyware programs, and D-Link firewall AV defenses rely on Kaspersky
Optimized Performance
D-Link’s AntiVirus solution has a built-in extreme-performance AV acceleration engine that allows D-Link’s
UTM firewalls to perform with a much higher throughput than other antivirus-capable UTM firewalls on the
Streaming-based Pattern Matching
A streaming-based scan engine inspects all payloads and matches the signature packet-by-packet. File-based
AV protection will never encounter a file-size limitation since D-Link firewalls do not need to store whole files
in memory for inspection purposes.
Fast Response Time
All AntiVirus signatures are updated hourly and made available through D-Link update servers worldwide.
Emergency signature releases protect against the latest, most virulent virus variations.
Comprehensive AntiVirus Signature Database
NetDefend’s proactive signature database protects each system against network worms, Trojans, and spyware
with signatures covering all Wild List threats and thousands of well-known OS exploits and application

NetDefend Web Content Filtering (WCF) Subscription
Web surfing control is becoming a critical concern for businesses of all sizes. D-Link’s Web Content Filtering
(WCF) service enforces access protection and management policy in terms of Internet resource allocation for
your organization.
NetDefend Web Content Filtering helps MIS monitor, manage, and control employee usage of and access to
the Internet. It puts management back in control, enabling a more business-orientated and cost effective use
of sometimes scarce Internet resources.
Organizations experience significant cost savings through:
1) A reduction in wasted staff time by reducing inappropriate web surfing.
2) Reduced Internet access costs and bandwidth savings by limiting and controlling non-business related
uses, thus improving network response.
3) Reducing legal exposure to workplace conflicts and liabilities (e.g. sexual harassment cases or child
pornography and the adverse publicity that such incidents can generate).
4) Reduced costs in recovering from attacks as much less inappropriate content will even be allowed to enter
the network.
Features and Benefits
Global Index Servers
Global index servers maintain databases of millions of URLs and collect real-time website information in order
to keep the data as current as possible. Multiple servers worldwide enhance performance and maximize
service availability wherever a NetDefend firewall is installed.
Performance Optimized
D-Link implements multiple index servers to enhance performance capacity and maximize service availability.
Categories of recently visited websites are cached locally in each UTM firewall to maximize performance for
subsequent requests.
Tight Integration with other D-Link Security Gateway Subsystems
D-Link allows you to define highly-granular policies for allowing or disallowing where and when access to
certain types of websites is permitted, and different policies can be applied to any combination of users,
interfaces, and IP networks.
Building networks for people
Static White and Black Lists
Define websites that will be explicitly allowed or blocked, independent of their classification. There are 32
default classification groups in NetDefend UTM firewalls to allow network administrators to control Internet
Active Content Handling
The WCF capabilities of D-Link UTM firewalls can strip potential malicious objects, such as Java applets,
JavaScripts / VBScripts, ActiveX objects and cookies, all of which are popular methods for hacker attacks.
Cost-Effective Web Content Filtering
D-Link’s WCF service is priced per firewall instead of per user, so an enterprise-level organization does not
need to contemplate a large TCO for licensing in order to manage the surfing privileges of all employees. One
subscription can provide web surfing control for an entire organization.
Multiple replicated databases are deployed worldwide to
maximize performance and availability.
2. A global database is queried for the
category of the web page.
2b. If the database does not contain the
requested information, the web page
is downloaded by the database and
analyzed using several techniques.
1. User requests a web page.
Public web server
3. If granted by the corporate surfing policy, the user
will gain access to the requested website.
