Violence maybe is the biggest difficulty of mankind nowadays. And a virtual unity here is not much different from the real world. Those dreamy times went away, when collective appearance of hacker was a sly man, breaking up defense of bank and pumping over a tidy sum on the account. Hard times are hard dispositions. Now hackers by an attack on a server block its work, and then propose owners the requirements. Virtual terror is in a clean kind. A few month goes without scandalous commentaries in the the media that one or another server was exposed to the ddos attack.A ddos attack is reduction from Distributed Denial Of Service Attack. The feature of this type of computer crime is that malefactors do not put the aim illegal access in the protected computer system with the purpose of burglary or elimination of information. Idea of this attack is to paralyze work of the attacked web site. The chart of ddos attacks is the next: on the server chosen as a target the enormous stream of fake queries is brought down from the great number of computers from different doomsdays simultaneously. As a result a server outlays all resources on protection of these queries and becomes unattainable basically. To get under pressure of ddos attack is a nightmarish scenario for any system administrator, specialist on safety or supplier of access. As a rule an attack begins instantly and without warning and not stopped in course of time - the system does not answer, a network is locked, routers are overloaded. An actual and fast answer to stop ddos attack is not easy to be found, and often depends on third parties, such as ISP providers. Frequently the most efficient means of ddos protection is a firewall installed. For example, most firewalls can be constructed so as to limit the number of simultaneous connections from any individual IP-addresses or networks, thus avoiding a number of simple attacks. dedicated servers are also needed to minimize the hurt that can be triggered by ddos attack. These servers are more trustworthy and they are capable of resist high loads over a longer period of time. From the right tuning of server the role of all applied applications depends not only but also frequently, the correctly configured server is less liable different births to the attacks on a refuse in service.
