7New Challenges and Trends in Security, SDN and IoT

7.1. Introduction

Nowadays, the classical architecture of networks is being left behind, to the detriment of new technologies, among which we can mention the SDN (software-defined network). The new technology has different characteristics and architectures that can cause different attacks compared to traditional networks. This scenario presents specific challenges that require appropriate security solutions.

The SDN architecture was developed with the aim of making a network virtual. It makes the control panel virtual by moving it from each peripheral device to a central network entity for control and rule generation, called the SDN controller.

Indeed, smart objects are beginning to dominate all areas, connected to one another via a network and evolving increasingly towards intelligence and automation. This considerable evolution presents limitations with respect to security challenges at every level. These specific challenges demand appropriate security solutions. This kind of network is a potential target for intrusion insofar as the connected smart objects and the automation they offer provide pirates with key control and spy points. These vulnerabilities make security especially important in the IoT/IoE.

7.2. SDN security

Networks are progressively migrating towards automation and virtualization, which opens the door to a new trend in security that is specific to SDNs.
