with the corona COVID-19 virus outbreak; the need for online jobs and working remotely has increased, many daily jobs that require face-toface communications has converted into online jobs as well, with all that and especially with the ever-evolving cyber-threats; comes a bigger need to provide more security for the cyber-space for a better and more reliable work environment. For those reasons and for others; many researches have been conducted to assure the security of computer networks using various ideas and based on different aspects and one of them comes the Software-Defined Networks (SDN) paradigm which is merely a new way of managing the network more that it is a new technology but, this methodology despite its short lifespan proved to be more and more reliable and there are many researches that use SDN to secure or patch issues in some other fields of technology or use other fields of technology to secure SDN and that proves how SDN is not just important and effective but, its ability to be integrated with other technologies. Over the last few years of its age; SDN has proved to be effective in solving some network management issues and provided some quick solutions for some threats but, in the same time with its ability to cure some cyberdiseases; it gives the opportunity for other cyber-threats to emerge.
