Every Industry Is A Target Of DDoS Attack: Verisign
A new report from the internet security firm Versign shows that Distributed Denial of Service (DDoS) attacks have increased in size, scope, and frequency. The report shows that there was an 85 percent increase in DDoS attacks during the fourth quarter of 2015.
This is quite a striking rise in their frequency given that the number of attacks has almost doubled when compared to the forth quarter of 2014. There was also a 15 per cent increase in DDoS attacks when compared to the third quarter of 2015. The attacks have become more persistent with some targets being attacked up to 16 times during a three month time period.
Verisign also recorded an attack in 2015 which targeted a company in the telecommunications industry that was sent 125 million packets per second (Mpps) which resulted in 65 gigabits per second being sent to the companies’ servers. This is quite an increase from an attack in 2014 where a flood of 91 Mpps was used in a DDoS attack. The average attack size observed by Verisign continues to be high at 6.88 Gbps, with nearly a third of attacks peaking over 5 Gbps, said Verisign.
Companies involved in IT, cloud, and software services were the most targeted, with 32 per cent of all DDoS attacks directed at them. Media and entertainment companies were not far behind though and received 30 per cent of the attacks that occurred in 2015 while the financial sector was the least affected by DDoS attacks and only received 15 per cent.
The most common attacks Verisign mitigated were User Datagram Protocol (UDP) floods, including Network Time Protocol (NTP), Domain Name System (DNS), and Simple Service Discovery Protocol (SSDP) floods, which collectively accounted for approximately 75 percent of attacks in Q4 2015.
With DDoS attacks on the rise, Verisign recommends that companies augment their existing DNS capacity with a managed DNS service or with one that is hosted in the cloud.
