Security Challenges in 5G Network: A technical features survey and analysis

5G networks control new technical concepts like ultra-low latency, ultra-high bandwidth, ultra-reliability, ultra-massive device access and manage the continually rising demands of diverse applications. The architecture and hierarchical framework of 5G networks need to understand and introduced. Security has been a primary focus for many telecommunications businesses since risks might have serious consequences for their front-line applications. A new class of security issues will be raised by network softwarization and new technologies including software-defined networking, network function virtualization, mobile-access edge computing and network slicing. This paper emphasizes the security concerns that 5G will raise and demands urgent security fixes. We also discuss the future of safe 5G systems and security fixes for these problems. To increase network security, DDOS attacks are detected and mitigated using a variety of SDN approaches.
