Security Study of 5G Heterogeneous Network: Current Solutions, Limitations & Future Direction

Now-a-days security study of heterogeneous systems within SDN based 5G Network is a highly prioritized research discussion. Usually 5G heterogeneous network manages all sorts of networks by using Software Defined intelligent Network System. Virtually the security system will also be designed based on control unit. The objective of this paper is to find the weaknesses of 5G heterogeneous network along with different barriers and difficulties and their corresponding countermeasures as well. This paper shortly discusses the vulnerabilities of different types of cellular networks integrated within 5G heterogeneous network along with its weakness, possible attacks and countermeasures. Finally, it also discusses a standardization method for the detection of security attacks on 5G networks.
