Application Layer Dos / Ddos Attacks On E Commerce Sites

APPLICATION-LAYER DoS/DDoS ATTACKS ON E-COMMERCE SITES ABSTRACT A recent increase of application layer Denial of Service attacks (DoS) on the Internet has swiftly shifted the focus of the research community from traditional network-based denial of service. Denial of Service (DoS) and the associated Distributed Denial of Service (DDoS) are simply an attempt by cyber-attackers to exhaust the resources available to a network, application or service so that genuine users cannot gain access. Cyber-attackers find application-layer most vulnerable and are able to device more creative methods of attack, are able to recruit other zombie systems referred to as botnets to amplify their attacks and the apparent difficulty of detecting and mitigating the attacks, all of these with little known solution. Application-layer DoS/DDoS attacks emulate the same request syntax and network level traffic characteristics as those of legitimate clients, thereby making the attacks much harder to be detected and countered. Moreover, such attacks usually target bottleneck resources such as disk bandwidth, database bandwidth, and CPU resources. This paper overviews DoS/DDoS concepts, the various types of denial of service attacks, application layer DoS/DDoS and mitigation techniques to curb the growing trend. Keywords: DoS/DDoS, Botnets, Application-layer INTRODUCTION/BASIC CONCEPTS OF DoS/DDoS In the past, Denial of Service attacks were mainly concentrated on exploiting vulnerabilitiesShow MoreRelatedEvaluating The Objectives Of An E Commerce Security Program1712 Words   |  7 Pagescompanies’ risk is one of many steps in developing a security program.
