A denial-of-service attack (DoS attack) or distributed denial-of-service attack (DDoS attack)
It is an attempt to make a machine or network resource unavailable to its intended users. Although the means to carry out, motives for, and targets of a DoS attack may vary, it generally consists of efforts to temporarily or indefinitely interrupt or suspend services of a host connected to the Internet.
Perpetrators of DoS attacks typically target sites or services hosted on high-profile web servers such as banks, credit card payment gateways, and even root nameservers. This technique has now seen extensive use in certain games, used by server owners, or disgruntled competitors on games.
One common method of attack involves saturating the target machine with external communications requests, so much so that it cannot respond to legitimate traffic, or responds so slowly as to be rendered essentially unavailable. Such attacks usually lead to a server overload. In general terms, DoS attacks are implemented by either forcing the targeted computer(s) to reset, or consuming its resources so that it can no longer provide its intended service or obstructing the communication media between the intended users and the victim so that they can no longer communicate adequately.
DDoS Prevention: By CloudFare
One of the many great features that CloudFlare provides is protection from Distributed Denial of Service (DDoS) attacks. A malicious party who wants to make your website or web service unavailable could try to overwhelm it with requests from compromised machines (or bots) all around the world. With a large enough volume of requests, your server may become overloaded and not be able to provide its services to legitimate clients. This is the typical scenario in a denial of service attack.
The attacking machines use the public domain name service (DNS) to look up the IP address that hosts your domain (www.sample.com) and send their traffic to that machine hoping to shut it down.
Signing up for CloudFlare is like taking your number out of the phone book, and putting in CloudFlare’s number under your name. When someone attempts to look up who hosts your domain, DNS will return an IP address in the CloudFlare network. If an attacker tries to take down your site, their traffic will go to CloudFlare machines around the world instead of directly to your web server. The CloudFlare network acts as a filter to block bad traffic and only send legitimate traffic through to your origin server.
