One third of IPv4 addresses affected by DoS over past two years

5 Nov 2017

A study conducted by a team of researchers at the University of Carolina San Diego, Saarland University, and University of Twente has revealed that one third of all IPv4 address space estimated to be in use have been affected by at least one denial-of-service (DoS) attack over the past two years. The researchers based their study on data from four global Internet measurement sources: backscatter traffic to a large network telescope; logs from amplification honeypots; a Domain Name System (DNS) measurement platform covering 60% of the current namespace; and a DNS-based data set focusing on DDoS Protection Services (DPS) adoption. Other main findings of the report: often targets are simultaneously hit by different types of attack; web servers were the most prominent DoS attack target; and an average of 3% of domain names registered in .com, .net, and .org were involved in DoS attacks daily; the most commonly targeted countries were the USA, China, Russia, France, and Germany.

Cybersecurity is among the main concerns of governments, Internet users, technical and business communities. Cyberthreats and cyberattacks are on the increase, and so is the extent of the financial loss. 

Yet, when the Internet was first invented, security was not a concern for the inventors. In fact, the Internet was originally designed for use by a closed circle of (mainly) academics. Communication among its users was open.

Cybersecurity came into sharper focus with the Internet expansion beyond the circle of the Internet pioneers. The Internet reiterated the old truism that technology can be both enabling and threatening. What can be used to the advantage of society can also be used to its disadvantage.

Internet Protocol numbers (IP numbers) are unique numeric addresses that all devices connected to the Internet must have. Generally speaking, two devices connected to the Internet cannot have the same IP number.

The Domain Name System (DNS) handles Internet domain names (such as www.google.com) and converts them to Internet Protocol (IP) numbers (and the other way around).
