Software defined networking, distributed denial of service, anomaly detection This research explains DDoS attacks and the anomaly detection as one of the famous detection techniques for intelligent networks. Such attacks can easily bring down the entire network by bringing down the controller. The centralized role of the controller in SDN makes it a perfect target for the attackers. However, the separation leads to the emergence of new types of distributed denial-of-service (DDOS) attacks on SDN networks. SDN is a new networking approach that is introduced with the goal to simplify the network management by separating the data and control planes. One of the famous attacks is distributed denial of service (DDoS). Issue of security is one of the big challenges of SDN because different attacks may affect performance and these attacks can be classified into different types. Software defined network (SDN) is a network architecture in which the network traffic may be operated and managed dynamically according to user requirements and demands. To learn more about the principles behind Kaspersky DDoS Protection, read this document.Volume: 8 | Issue: 2 | Pages: 2724-2730 | April 2018 | Abstract The complete text of the stats is available at. Kaspersky Lab’s stats on botnet activity in Q1 was prepared based on the data collected by DDoS Intelligence. DDoS Intelligence is a system that analyzes the information sent from C&C servers to botnets, and aims to improve protection against DDoS attacks. Thus, Kaspersky DDoS Protection combines Kaspersky Lab’s proven expertise with in-house technology such as DDoS Intelligence. Kaspersky Lab recommends the use of dedicated security solutions to filter cybercriminals’ junk requests from legitimate web traffic. web resources,” commented Evgeny Vigovsky, Head of Kaspersky DDoS Protection, Kaspersky Lab. Although cybercriminals do not limit their DDoS toolkits to botnets alone, this is still a widespread and dangerous tool, and it demands preventive protection measures from potential targets, i.e. This often makes it more complicated to investigate attacks, take down botnets and catch those responsible. “A DDoS attack is often a cross-border effort the customer is located in one country, the executor in another, the C&C servers are hosted in a third country, and the bots involved in the DDoS attack are scattered across the world. China and the USA’s leading positions in both rankings can be explained by the relatively cheap prices for web hosting in these countries, so most data centers are located there. These attacks were commanded by C&C servers predominantly located in the USA, China and the UK. Information systems located in China, the USA and Canada in Q1 suffered most from DDoS attacks. These affected targets in 76 countries, up 15% from the 66 countries affected in Q4, 2014. There were a total of 23,095 attacks in Q1. The most protracted botnet attack in Q1 was almost six days long. In Q4 2014, the equivalent figure was 16. The greatest number of attacks on a single web resource in Q1 was 21 – about two attacks a week.
Servers in the USA, Canada and China were most frequently targeted, while the top 10 victims also included resources in Europe and the Asia-Pacific region, according to Kaspersky Lab’s latest stats. Cybercriminals in Q1 2015 carried out more than 23,000 botnet-assisted DDoS attacks on web resources located in 76 countries.
