and respond quickly to network attacks

The IPS service for D-Link NetDefend firewall adopts 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.

IPS signatures are constantly created and optimized signatures via the Auto-Signature

Sensor System. Without overloading existing security appliances, IPS signatures ensure a

high ratio of detection accuracy and the lowest ratio of false positives.

NetDefend users need to register their firewall to receive IPS update service from the

NetDefend Center. The current status of all registered products will be presented, including

Model Names, MAC addresses, Serial Numbers, Registration dates, and IPS Service

Expiration dates.

The NetDefend Center includes a “NetDefend Live” service for users. 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 an around-the-clock basis. The main purpose of NetDefend Live

is to help users 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.
