Assuming that one of the attacks used to defraud Zambian banks was a DDoS attack, describe in depth with the aid of a diagram what a Distributed Denial of Service (DDoS) attack is. Give the steps that could be followed by the banks in the event of the DDoS assault on their systems | According to Microsoft's estimate, in 2014 about one half if all adults connected to the internet werevictims of cybercrime. This costs the world economy 500 billion dollars; 20% of all small and medium-sized enterprises (SMES) have been hit. These estimations are confirmed by Meril Lynch GlobalResearch, who, in a 2015 report, also predict a potential "Cybergeddon" in 2020, when cybercrimecould extract up to one-fifth of the value generated by the Internet.As far as the African continent is concerned, there are fewer available data this shows the absence ofmeasuring tools and of control of cybercrime.However, and to serve as an illustration: a study conducted by International Data Group Connectshowed that each year, cybercrime cost the South African economy an estimated 573 million dollars.For the Nigerian economy the cost was estimated to be 500 million dollars, and for the Kenyaneconomy, 36 million dollars.Proportionally speaking, for middle income countries this represents enormous sums. Another studyconducted by Deloitte and dating back to 2011 showed that financial institutions in Kenya, Rwanda,Uganda, Tanzania, and Zambia had sustained losses of 245 million dollars, attributable to cyberfraud.Lastly, several Zambian commercial banks were defrauded of over 4 million dollars in the first semesterof 2013, as a result of a complex cybercrime scheme involving Zambians as well as foreign nationals.In francophone Africa, the phenomenon is mostly to be found in the main regional economies. Forinstance, in 2013 the estimated cost of cybercrime in the Ivory Coast was 26 billion CFA Francs (3.8million euros). In Senegal the cost was estimated to be 15 billion CFA francs (22 million euros). At aninternational forum on cybercrime in 2016 in Dakar, Charles Kouamé, in charge of governance in theIvorian Authority for the regulation of telecommunications, pointed out that 1.409 complaints had beenlodged and acted on by the Ivorian courts last year. According to him, the global volume of Web basedfraud in the country seems to have started to decrease, falling from 5.8 billion CFA francs (8.9 millioneuros) in 2014 to 4 billion CFA francs (6,1 billion euros) in 2015.These figures show the size of the problem in a part of the world which is currently experiencingexponential growth, fed by the rise in the prices of raw materials and the boom in the technologicalsector, to which one could add the rise in the incomes of the middle classes. Even if they can't buy the usual computer "kit" (PCs, printers, routers etc) they can now connect to the Internet with smart phones,the prices of these devices having dropped significantly in the last ten years.This explains why, in 2013, in Sub-Saharan Africa alone 311 million mobile phone users were counted|(a penetration rate of 36 %). The figure should reach 504 million in 2020 (49% penetration rate). For itspart, the International Telecommunications Union (ITU) estimates that one African out of every five nowuses the Internet.Source: (Online] https://www.scidev.net/sub-saharan-africalicts/feature/cybercrime-africa-facts-figures.html#-text=Hundreds%20of%20millions%20of%20cyber%20attacks%20take%20place,a%20heavy%20price?% 20BY%3A%20Jean%2OShiloh%2C%20Amzath%20Fassassi (Accessed on: 11 May-2020]
