DDoS attackThe end goal of Denial-of-service attack (DoS attack) or distributed denial-of-service attack (DDoS attack) is to make a resource unavailable to its users. The attack can be carried out on different levels, depending on the target and people involved. In essence, the attack represents a highly intense attempt by one person or more to hinder web sites or specialized internet services from running properly, causing financial losses to the owner of that resource.

Depending on the motivation behind the attack, different targets might suffer from it. The attack can be implemented by a single person, carrying out a personal agenda. Such an attack is highly unlikely to cause too much trouble and will only be temporary. A much bigger problem are organized attacks performed by a group of individuals in pursuit of financial gains. Such attacks can be sustained for longer periods of time and might as well ruin companies relying on online presence. Banks, online retailers, government sites, payment gateways and even root nameservers can become easy prey for organized DDoS attacks.

The most common method of attack involves flooding the web site (and web server along with it) with external communications requests to such a level that it cannot respond to legitimate traffic generated by regular users. Needles to say, precious business is driven away. Unprotected parties might sometime be forced by their hosting provider to move their website to different hosting, due to the fact that the attack intended to render one site unusable is preventing the whole web server (thousands or tens of thousand sites) from delivering their content to visitors.

Saboteurs are usually after a hefty ransom, threatening to continue the attack for as long as they have to, unless the amount is paid. Such people are considered outlaws and are threatened by up to 10 years in prison, depending on local law.

There are ways to protect your online business from such attacks and usually it is best to be proactive. Wikipedia.org and Cisco.com are two good points to start from, should you be interested in learning more about prevention and actions you might take. If you are the proud owner of a small website with modest amount of traffic you shouldn't be too worried about the DDoS attack. That does not mean you can't monitor your website or server. For as low as 9$ per month you can be aware of whether your site is being a victim of malevolent attacks.
