D-Link adds CAPTCHA to home routers to prevent against attacks

A series of recent Internet security attacks on home and small office computers are compromising networks where users least expect it - their routers. These malicious software invasions, in which users unknowingly download a Trojan horse when performing common tasks, invade the router to detect wireless capabilities, then alter the victim's domain name system (DNS) records so that all future traffic is diverted through the, attackers' network first.

In response to the growing number of these attacks and subsequent user security concerns, D-Link Systems Inc. has integrated CAPTCHA, a system, designed to detect whether responses are human or computer-generated, into its home and small office routers as an extra safety measure.

CAPTCHAs are used to prevent malicious software from performing actions that degrade the quality of service on a network, such as those found in worms, viruses and Trojan horses.

D-Link of Fountain Valley, California is a global provider of connectivity solutions for small, medium and large enterprise business networking. The company designs, develops and manufactures networking, broadband, digital electronics, voice and data communications solutions for the digital home, small office/home office (SOHO), small to medium business (SMB), and workgroup to enterprise environments.

The term CAPTCHA is an acronym for Completely Automated Public Turing test to tell Computers and Humans Apart.

CAPTCHA is a type of challenge-response test used in computing to ensure that responses are generated by humans, not computers. A common type of CAPTCHA requires the user to type letters or numbers from a distorted image that appears on the screen.

"Unlike other brands, the majority of D-Link routers are not as easy to be compromised since our design is proprietary. However, we're excited to be the first in the market to announce we have taken the initiative to implement CAPTCHA into our CNC router machines, thus providing yet another layer of security to our customers," said AJ Wang, chief technology officer of D-Link.
