5G systems to meet these high-performance goals, a variety of cutting-edge technologies are used. Among these are network slicing, D2D communications, mm Wave, softwaredefined networks (SDN), heterogeneous networks (HetNet), massive multiple-input multiple-output (MIMO), and network functions virtualization (NFV). Despite these advancements, the standardization process for 5G wireless technology is still in its early stages. Security of wireless communications is a hot topic, and 5G offers unique prospects and difficulties in this field. Security features like secrecy, integrity, and authentication can be provided, although there are limitations due to the limited bandwidth of the broadcast format. Modern cellular networks provide security threats at the media access control layer (MAC) and physical layer (PHY) because of potential attacks, vulnerabilities, and privacy issues. Features like communication route protection, mutual authentication between the network and user equipment (UE), and user identity management are included in conventional security designs for voice and data security. One example of how legacy cellular networks provide a high degree of security and dependability is Long Term Evolution (LTE).
technology is 5G cellular network security. The way we use and engage with technology is about to undergo a radical change thanks to the fifth generation of mobile networks, which also presents new security problems and opportunities. Since 5G networks are expected to be more intricate and interconnected than those of previous generations, strong and all-encompassing security measures will be necessary to guarantee that confidential and safe sensitive data is transferred over the network from cyber-attacks. It is the joint responsibility of network operators, device manufacturers, and service providers to ensure the security of 5G networks. Network administrators must enforce stringent security measures and make sure that security is incorporated into the network architecture from the beginning. It is the responsibility of device manufacturers to guarantee that their products are patched quickly, have the most recent security software and hardware, and are safe. In addition to putting policies in place to identify and handle security problems, service providers need to assume accountability for the security of the apps and services they provide.

1.INTRODUCTION
Both encryption of user communication and mutual authentication between UEs and base stations are standard operations. However, because 5G has special qualities like low latency and excellent energy efficiency, there are further security concerns. This paper explores the quickly developing field of security protocols designed to satisfy 5G network specifications. It carefully looks at how different state-of-the-art technologies, such as device-to-device interactions, heterogeneous networks, software-defined networks (SDN), massive multiple-input multiple-output (MIMO), and the Internet of Things (IoT), actively contribute to improving the overall security framework of 5G networks. Examining these cutting-edge technologies highlights how 5G's security environment is dynamic and how conventional methods might not be sufficient to handle the new threats that arise from this generation's unique characteristics. For example, the Internet of Things brings a variety of networked devices, therefore strong security measures are required to ensure the integrity of data transfer. Like this, software-defined networks offer new factors to ensure secure communication while also providing flexibility and programmability to network management. While they
The existing 4G/International Mobile Telecommunications (IMT)-Advanced Systems are not as capable as the fifth generation (5G) of wireless systems, which represents a breakthrough in mobile wireless telecommunications. Beyond merely being a cellular network, 5G is an allencompassing system with distinct features and objectives that unlock a multitude of service opportunities. One of the primary goals of 5G is to provide mobile broadband users with denser networks and higher bandwidth than 4G. The integration of massive machine-type communications and device-to-device (D2D) communications capabilities makes the network more flexible. Furthermore, 5G planning includes enhancements for Internet of Things (IoT) implementation, with a focus on low latency and low energy usage. The groundbreaking nature of 5G wireless systems is further demonstrated by its eight key characteristics: 100% coverage, an astounding 99.999% availability, 1000 times more bandwidth per unit area, ultra-fast (1–10 Gbps) connections to field endpoints, an astounding 1 millisecond latency, the ability to connect 10-100 times more devices,
