点击翻译按钮获取中文摘要

Attacks on data availability are commonly referred to as Denial of Service (DoS) attacks, with Distributed Denial of Service (DDoS) attacks being their most potent form. Nowadays, the means to carry out sophisticated and potent DDoS attacks are within easy reach of anyone with a computer and an Internet connection. Do-it-yourself simple-to-deploy DDoS attack tools can be obtained for only a few $100. Botnets-for-rent are also available for as little as $50 per one hour of rental time. Due to their great affordability combined with a significant damage potential, DDoS attacks have emerged as the weapon of choice for a number of different individual/groups, ranging from financially-motivated cyber criminals to politically-motivated ‘hacktivists’. Last year in the US alone an average of 28 DDoS attacks occurred every hour, with the average cost of 1 hour of DDoS-caused downtime estimated at $100,000. More than 40% of companies affected by DDoS have experienced consequent losses of over $1,000,000 (each).
