Impact of DoS Attack in Software Defined Network for Virtual Network

Abstract

A virtual network is a computer network which does not contain any physical link between two computational nodes instead they connect through the virtual links. In recent years the virtual network is managed by Software Defined Network (SDN). SDN is one of the most emerging network technologies in the current trends. Most of the companies configure their networks in SDN. It has been found important to understand the security issues that are being raised in any large scale developments from any new technologies that have been raised in recent years. Though the system acquires lot of benefits from SDN the system have to do some little work in security phase. This work confers four kinds of Denial-of-Service (DoS) attacks that are specific to networks in the OpenFlow SDN in different layers. Those attacks are Ping of Death, HTTP Unbearable Load King, SYN flood and Smurf attack. We introduced these attacks in SDN. These have been emulated on Mininet and an analysis is provided that was obtained on the consequence of these attacks. The DoS attack that is more severe than others has been found out and a suitable prevention techniques for that DoS attack is suggested.

Attacks classification and security mechanisms in Wireless Sensor Networks

“…In a WSN, resources depletion leads to the complete collapse of the network. Attackers aim to waste limited energy resources of nodes using various processing and transmission tasks [34].…”

A Review of Anomaly Detection Techniques and Distributed Denial of Service (DDoS) on Software Defined Network (SDN)

“…Though the system acquires many benefits from SDN, the system has to do some work in security phase. This work confers four kinds of DoS attacks that are specific to networks in the OpenFlow (OF) SDN in different layers [5].…”

“…The largest of these issues was a lack of a single clear motivation for deployment. Although many applications for the technology could be described, none of them provided a compelling reason for system deployment [5]. Without this reason, network operators had no incentive to deploy the extensive hardware upgrades that would have been required to support the system [6].…”

“…This focus was prompted by the increase in traffic volumes as the internet grew in size, leading administrators to search for a new control interface for their networks. Early technologies attempted different methods of creating a separation between control and data planes [4,5]. However, many of these technologies proposed the use of standard APIs for control of the data-plane, while leaving the operation of the data-plane essentially unchanged.…”

“…However, many of these technologies proposed the use of standard APIs for control of the data-plane, while leaving the operation of the data-plane essentially unchanged. These designs left little incentive for adoption by hardware vendors [5], as they would have allowed new competitors access to their products. New technologies were soon proposed that created clean-slate designs for centralized network control [7,8].…”
