## 1 Introduction  
The next generation of wireless networks will require a unified platform to support the vast numbers of devices, users, and services with different data rates and latency requirements. Current wireless technologies like 3G and 4G-LTE have several limitations that restrict any possible enhancement of the systems to meet these demands. Accordingly, researchers have developed an advanced wireless communication technology called 5G to satisfy the requirements above. After several scientific research studies, it was found that this fifth-generation technology has limitations too: it cannot be used for long-distance communication or low-power wide-area technology. This indicates that current communication technology will not be fully and effectively able to meet demands in the future. A highly advanced digital civilization backed by limitless wireless connectivity is also anticipated to have arisen by the year 2030 [1]. Within the context of 5G technology, the Internet of Things (IoT) has arisen as a groundbreaking idea, where technologies and solutions are incorporated to connect objects, people, platforms, and software via the Internet. To create comprehensive IoT networks, deviceswill be endogenously fully equipped with IoT modules that enable D2D communication with one another [2]. Furthermore, RAT will be supported by 5G to connect these devices. New radio technologies, such as NOMA, massive MIMO, mmWave, and several other IoT communication technologies, will be introduced in the 5G network. One of the primary requirements for 5G systems and beyond is security related to 5G technologies. To investigate security in networks, 4G networks use cryptography protocols for user authentication [3], while 3G networks use two-way authentication to prevent connection establishment with fake base stations [4]. A new age has begun with the introduction of 5G technology, which presents distinct security and privacy challenges beyond those faced by earlier systems. An innovative approach to security procedures is necessary given the changing architecture and the introduction of new services. Researchers have added new ideas like visibility and centralized policy in addition to the fundamental security principles of confidentiality, integrity, and availability. These updates are intended to strengthen data protection in the face of evolving threats by enhancing security safeguards [5; 6] as shown in Figure 1.  
One of the most important security requirements in the 5G security model is data confidentiality; it is the parameter that can protect the transmission data from disclosure to unauthorized entities: it means ensuring that the sender's message in the 5G network is only readable by the proposed destination. To preserve data secrecy in the context of 5G network applications, encryption methods have evolved into essential instruments. Data within 5G networks can be safely secured and decrypted by using symmetric key encryption. Sensitive information is kept secure by being protected from unauthorized access or interception due to this critical security defense [7]. Data integrity relates to keeping data from being altered or modified while transformed from one location to another. To achieve the principle of integrity authentication technique used by 5G-AKA (authentication and key agreement), the fact that the 5G new radio (NR) offers user integrity protection is a significant improvement in 5G security. This is significant because user plane integrity protection was not supported by 4G. Small data transmissions can take advantage of this new feature, especially for IoT devices with constrained bandwidth [8; 9]. Availability issues in most cases are related to DoS attacks and are conducted in a wireless network by jamming. Spread-spectrum techniques can prevent jamming effectively, but they cannot be used in IoT nodes with limited resources (e.g., sensors). Fifth-generation networks do not implement new techniques to test availability.
