Denial of Service attacks and mitigation techniques: Real time implementation with detailed analysis

Amongst various online attacks hampering IT security, Denial of Service (DoS) has the most devastating effects. It has also put tremendous pressure over the security experts lately, in bringing out effective defense solutions. These attacks could be implemented diversely with a variety of tools and codes. Since there is not a single solution for DoS, this attack has managed to prevail on internet for nearly a decade. Hence, it becomes indispensable to carry out these attacks in small test bed environments in order to understand them better. Unlike other theoretical studies, this project lays down the steps involved in implementing these attacks in real time networks. These real time attacks are measured and analyzed using network traffic monitors. In addition to that, this project also details various defense strategies that could be enabled on Cisco routers in order to mitigate these attacks. The detection and mitigation mechanisms designed here are effective for small network topologies and can also be extended to analogous large domains.
