Up 1000% since 2005
The distributed denial-of-service (DDoS) attacks have reached the 100 Gbps attack barrier for the first time in 2010, said a report by Arbor Networks, a provider of security and network management offerings.
The sixth edition of the Network Infrastructure Security Report said Botnet-driven DDoS attacks are likely to continue as a low cost, high-profile form of cyber-protest in future.
The report also reveals attackers are targeting infrastructure such as DNS, VoIP and IPv6.
Arbor Networks solutions architect Roland Dobbins said network operators are facing an Internet insurgency driven by the ubiquity of botnets.
Dobbins added, "Adding to the challenges facing operators is the increasing number of attack vectors, including applications and services, not to mention the proliferation of mobile devices."
Mobile and fixed wireless operators may be the least prepared to defend themselves and their customers against attack, said the report.
Operators have expressed concern over lack of visibility into IPv6 network traffic and their inability to control that traffic to the same degree they control IPv4 traffic.
The report said DNS has emerged as one of the easiest ways to DDoS a server/service/application.
