The websites of Novosti-Armenia (newsarmenia.am) and ARKA (arka.am) news agencies came Tuesday under heavy DDoS-attacks, hampering access to these resources for half an hour.
An inquiry found that the attacks were carried out from Russian IP addresses, but this does not mean that the order came from that country. The administrations of both websites have managed to eliminate the problem.
DDoS attack is short for Distributed Denial of Service Attack. DDoS is characterized by an explicit attempt by attackers to prevent legitimate users of a service from using that service. There are two general forms of DoS attacks: those that crash services and those that flood services.
The most serious attacks are distributed and in many or most cases involve forging of IP sender addresses so that the location of the attacking machines cannot easily be identified, nor can filtering be done based on the source address.
