The Impact

One of the most notorious security issues in the IoT is the Distributed Denial of Service (DDoS) attack. Using a large number of agents, DDoS attack floods the host server with a huge number of requests causing interrupting and blocking the legitimate user requests. This paper proposes a detection and prevention algorithm for DDoS attacks. It is divided into two parts, one for detecting the DDoS attack in the IoT end devices and the other for mitigating the impact of the attack placed on the border router. Also, it has the ability to differentiate the High-rate from the Lowrate DDoS attack accurately and defend against these two types of attacks. It is implemented and tested against different scenarios to dissect their efficiency in detecting and mitigating the DDoS attack.

This article describes how in the summer of 1999, the Computer Incident Advisory Capability first reported about Distributed Denial of Service (DDoS) attack incidents and the nature of Denial of Service (DoS) attacks in a distributed environment that eliminates the availability of resources or data on a computer network. DDoS attack exhausts the network resources and disturbs the legitimate user. This article provides an explanation on DDoS attacks and nature of these attacks against Smartphones and Wi-Fi Technology and presents a taxonomy of various defense mechanisms. The smartphone is chosen for this study, as they have now become a necessity rather than a luxury item for the common people.

Global Financial System

One of the key areas in the formation of a single financial market within the Eurasian Economic Union (hereinafter, EAEU or Union) is the development of a single payment space (SPS) of the Union. In the context of growth and transformation of the risks of the payment and settlement infrastructure (PSI) of the global financial system (GFS) (sanctions, systemic, operational and other risks), the problem of effectively neutralizing their impact on the PSI of the EAEU countries is highly topical. The article clarifies the conceptual apparatus associated with the transformation of risks for the PSI of the GFS, and carries out their systematization. Sources of operational risk of the GFS’s PSI, including the threat of an increase in cybercrime, are analyzed. The authors assert that the main type of operational risk for the PSI of the GFS in the future will evidently be cyberattacks using trojans, ransomware viruses and phishing, as well as blocking user access to Internet sites using DDoS attacks. Nowadays, the number of DDoS attacks in Russia has been growing for several years in a row, and this growth may intensify in 2021 due to a number of factors set out in the article. It is indicated that, in Russia and other EAEU countries, growth in cybercrime is one of the main threats to the stable functioning of the national PSI as well as credit and financial systems in general. In this regard, the article substantiates the need to develop regional cooperation on cybersecurity issues within the EAEU using the experience of the European Union, where this issue is paid very serious attention. Besides, it is advisable to build up international cooperation between the countries of the world within the UN in order to enhance the cybersecurity of the GFS’s PSI and ensure the successful development of the SPS in the EAEU.

At present, issues related to information security are highly relevant. DoS and DDoS attacks are carried out by cybercriminals quite often, because cyberattacks can bring almost any system to failure, leaving no legally significant evidence. At the same time, the failure of the attacked subsystem can be an intermediate stage towards the target system. The most vulnerable to DDoS attacks are online stores, online payment systems, news resources and companies, whose activities depend on the frequency of user access to the resource. The main methods of protection against cyberattacks and DDoS attacks, in particular, are currently antivirus programs and firewalls. The article presents a description of some types of DDoS attacks as well as the results of a comparative analysis of several existing methods of networks security from DDoS attacks, which will simplify the choice of the optimal solution to ensure reliable protection of a telecommunication facility. Considering all the advantages and disadvantages, the method of organizing a network protection system against DDoS attacks based on the technology of artificial neural networks is the most suitable solution for ensuring the information security of networks of various purpose.

Internet becomes unavoidable and it provides us with a wealth of information and allows us to keep in touch with the outside world. However, there can also be risks on the internet that is, for example, even a naive hacker can access information and easily learn to generate a large scale DDoS attack with the help of downloadable user-friendly attacking tools. Nowadays, this has made even small businesses in trouble. One of the extensive DDoS attacks was done on October 2016 which is called “Mirai botnet”. In that, the attackers send 30 million packets per second to attack the financial department, industries, home system, etc. were affected. In the future, the attackers may hit the hardest even as banks, government sectors, and corporate sectors, etc. On DDoS attack time, the attackers are sending a lot of malicious packets to the server/victims. So the attacker’s throughput is increased and legitimate user throughput is decreased on time of the attack. In this paper, a novel approach is proposed to detect the DDoS attacks using Chi-Square method which compares the normal packets and current packets statistics to discriminate whether the particular flow is DDoS or not. Further; it identifies the IP address of attacking source using entropy statistic. The proposed method can be used to control internet crimes. The experimental results show that the proposed method outperforms the existing approaches by detecting the DDoS attack and also by identifying the wrongdoer IP address. In addition, it takes minimum time to perform the above.
