Cybercriminals have started launching distributed denial-of-service (DDoS) attacks against networks that transmit data over IPv6 (Internet Protocol version 6), according to a reportpublished recently by DDoS mitigation vendor Arbor Networks.
Even though 2011 was the first year when IPv6 DDoS attacks were recorded, such incidents remain rare because they are not economically relevant for Internet criminals.
Some companies have projected increases of more than 100 percent for their IPv6 traffic volumes over the next 12 months, but the changes will be insignificant compared to the overall traffic volume.
The majority of organizations remain reluctant to switch to the new IP protocol version because their existent network security and traffic analysis equipment is not fully compatible with it.
Many infrastructure solutions currently do not offer the same features and functionality for IPv6 as they do for IPv4. This lack of feature parity means that security teams do not have the same visibility and mitigation capabilities when trying to identify and block IPv6-based attacks against targets.
