The use of distributed denial-of-service (DDoS) attacks by cybercriminals remains an effective and affordable strategy to compromise large targets. DDoS attacks topping 20Gbps during the first two quarters of 2014 doubled when compared to all four quarters of 2013 - and there have been more than 100 DDoS-related attacks with speeds of 100Gbps or higher so far.
Large-scale DDoS attacks are most worrisome for security experts, as thousands of compromised machines can flood targets with tremendous amounts of traffic. As more households have faster Internet service, the threat is becoming more complicated and difficult to properly prevent.
"The frequency of very large attacks continues to be an issue, and organizations should take an integrated, multi-layered approach to protection," said Darren Anstee, Arbor Networks Director of Solutions Architects, in a statement. "Even organizations with significant amounts of Internet connectivity can now see that capacity exhausted relatively easily by the attacks that are going on out there."
