CloudShield Helps Mitigate DDoS Attacks at EveryDNS.Impact on DNS (Domain Name System) A system for converting host names and domain names into IP addresses on the Internet or on local networks that use the TCP/IP protocol. For example, when a Web site address is given to the DNS either by typing a URL in a browser or behind the Customers Solved within Minutes of CloudShield Installation SUNNYVALE, Calif. -- CloudShield Technologies, Inc., a leading provider of IP services control and security solutions, has helped stop a major distributed denial-of-service (DDoS) attack aimed at EveryDNS, an organization that offers free authoritative Domain Name System (DNS) services to the public with over 100,000 domains hosted today. EveryDNS first noticed the behavior, which knocked the site offline and affected more than 100,000 customers, on Friday. With the help of DNS experts, including Richard Steenbergen of nLayer Communications, EveryDNS was able to completely stop the attack by Saturday, but the activity resumed on Tuesday. At that time, EveryDNS contacted CloudShield, who responded immediately to help mitigate the attacks on the EveryDNS infrastructure. CloudShield was able to deliver and install an effective working solution within a few hours. The attacks that began Friday had changed and needed deep packet inspection Analyzing network traffic to discover the type of application that sent the data. In order to prioritize traffic or filter out unwanted data, deep packet inspection can differentiate data, such as video, audio, chat, voice over IP (VoIP), e-mail and Web. (DPI (Dots Per Inch) The measurement of the resolution of display and printing systems. A typical CRT screen provides 96 dpi, which provides 9,216 dots per square inch (96x96). Flat panel displays from 110 to 200 dpi have also been developed. ) capabilities to accurately identify and classify the attack versus valid DNS queries. CloudShield was able to mitigate the attacks within minutes of installation. The other key piece to solving the problem was provided by nLayer Communications, a leading provider of wholesale high-performance Internet capacity, operating an advanced IP/MPLS IP/MPLS Internet Protocol/Multi-Protocol Label Switching network spanning North America North America, third largest continent (1990 est. pop. 365,000,000), c.9,400,000 sq mi (24,346,000 sq km), the northern of the two continents of the Western Hemisphere. . nLayer Communications responded to the Denial of Service attack An assault on a network that floods it with so many additional requests that regular traffic is either slowed or completely interrupted. Unlike a virus or worm, which can cause severe damage to databases, a denial of service attack interrupts network service for some period. against EveryDNS and quickly filled the company's regular Internet circuits by donating a gigabit/sec of network capacity.
