A Software Defined Network (SDN) architecture is used to protect against SLOW HTTP DOS attacks

In this digital era, all the information are stored and accessed digitally by large scale of users across the world. Where there is confidential information, there lies the threat as well. Analogous to this, several digital security threats have evolved drastically in the past years. Researchers have proposed many mitigation methods to overcome such hazards. However, there are some drawbacks along with those methods in terms variety of performance metrics. In this project, we have proposed a solution for such security threats that occur in Software Defined Network (SDN) environment. Our proposed work has completely removed the presence of attack from the system. We implemented 4 different scenarios to illustrate the working efficiency of our system. The first one is SDN architecture with no attack, the second one is SDN architecture with slow HTTP DoS attack, the third one is proposed SDSec architecture with no attack and the final one is proposed SDSec architecture with slow HTTP DoS attack. Each of these scenarios is implemented as well as explained in detail. Finally, the performance of the system is analyzed in terms of throughput, delay and packet delivery ratio. The experimental observation stands for the novelty and efficiency of the proposed system
