As well, peak bandwidth of DDoS in 2013 exceeded 300 Gbps, which represents over three times that of 2010. The biggest peak bandwidth of DDoS in 2010 exceeded 100 Gbps, which represents 100% increase over the size of attack in 2009. Nowadays, DDoS attacks are able to launch a destructive power in a single attack. In 2011, DDoS attacks devastated five high-profile websites, namely, Visa, MasterCard, Sony, WordPress, and the CIA. In January 2001, Microsoft lost approximately 500 million USD over the course of a few days from a DDoS attack on its site. Likewise, during the DDoS attacks against eBay, availability was degraded from 100% to only 9.4%. According to the bookseller Amazon, the DDoS attack was a reason for losing 600,000 USD during the 10 hours of downtime. Analysts estimated that during the three hours Yahoo web site was down it lost about 500,000 USD.
DDOS ATTACK TOOL 2015 SERIES
Historically, a series of DDoS attacks that occurred in February 2000 against Amazon, Yahoo, and eBay websites had caused an estimated cumulative loss of 1.2 billion USD. Compared to the previous researches, our framework’s design provides an efficient protection for web applications against all sorts of DoS/DDoS attacks. Thirdly, the flexible advanced entropy based (FAEB) scheme is to eliminate high rate DDoS (HR-DDoS) and flash crowd (FC) attacks. Then, it traces back the true attacking IP source. Secondly, the service traceback oriented architecture (STBOA) scheme is to validate whether the incoming request is launched by a human or by an automated tool.

Firstly, an outer blocking (OB) scheme blocks attacking IP source if it is listed on the black list table. The innovative design of the FCMDPF framework handles all aspects of HTTP-based DoS/DDoS attacks through the following three subsequent framework’s schemes (layers). Therefore, this research aims to fix this gap by designing an alternative solution called a flexible, collaborative, multilayer, DDoS prevention framework (FCMDPF). Despite many researchers’ efforts, no optimal solution that addresses all sorts of HTTP DoS/DDoS attacks is on offer.

However, now this merit is threatened by complicated network-based attacks, such as denial of service (DoS) and distributed denial of service (DDoS) attacks. If you're in the mood for 120 pages of security data, the report is available online for free.The growth of web technology has brought convenience to our life, since it has become the most important communication channel. The increase of DDoS threats has also lit a fire under the firewall and DDoS mitigation business, as companies reported that 74% of their customers asked for more DDoS protection services during the past year.īesides DDoS attacks, the Arbor Networks 11th Annual Worldwide Infrastructure Security Report includes information on other security threats affecting companies around the world. Most of these attacks were attributed to "criminals demonstrating attack capabilities" while in second and third place came "online gaming-related" and "criminal extortion attempts."įor the first time, DDoS attacks that targeted DNS services were more frequent than the ones targeting HTTP, and SIP/VoIP attacks also grew to 19% from 9% last year. This figure went up from 29% last year and 19% two years ago, showing a greater dependency on online services and especially their "online" status.Īdditionally, 44% of all respondents also said they saw more than 21 DDoS attacks in a single month while 9% also claimed they saw DDoS attacks carried out via IPv6 infrastructure for the first time. DDoS attacks targeting DNS services surpassed HTTP for the first timeģ3% of all respondents said they were affected by DDoS attacks launched against cloud services. Two-thirds of the total DDoS attacks targeted end customers while the other third of attacks were aimed at the ISP itself, and inadvertently affected its customers as well. The report, which included responses from 354 industry professionals, showed that DDoS attacks, in general, grew in intensity, and besides the single 500 Gbps attack, companies also reported incidents that reached peak values of 450 Gbps, 425 Gbps, and also 337 Gbps.įurthermore, 20% of the respondents also admitted they saw attacks of over 50 Gbps peak value while another quarter reported on peak attacks that reached over 100 Gbps, values much greater than in the past years. Arbor Networks’ 11th Annual Worldwide Infrastructure Security Report reveals that, for the first time in history, a company reported a DDoS attack that surpassed the 500 Gbps mark, something that was almost unbelievable only a few years back.
