Answer:

Introduction

5G network is mobile communication that provides data and voice communications which can be incorporated to other technologies of internet of things (IoT) [1]. This network provides services to vertical companies that incorporate various forms of communication and networking services. There are various technologies that promote the capability of 5G. These technologies are Network finance Virtualizations, and Software Defined Network. These technologies enable 5G to server many companies more effectively.

With the new 5G technologies, an emergence of new threats that comes into play. These threats raises various security issues that need to be address in order to ensure that the services provided by the 5G network is efficient and more reliable. 

Background

The main aim of using 5G network is to ensure that there is high and reliable level of security across the entire mobile network. 5G therefore is expected to provide quality solutions to the existing mobile networks problems using other networks such as 4G, 3G and 2G. There are main areas that are targeted by the attackers in computer networks [2]. These are network access, user equipment and mobile core and external networks. 5G network therefore comes with solutions on how to address and manage these security issues as discussed below.

Network equipment

Network or user equipment consists of devices such as tablets and smartphones that are 5G enabled. These devices are mainly targeted due to their popularity in usage, use of third party programs that are open source, having a wide connectivity variety ranging from wifi, Bluetooth, 2G, 3G and 4G network. Using these devices an attacker can easily penetrate into a network using malwares, which hide innocently on downloadable applications. In auditing, malicious attack such as information theft, hacking can also occur on other networks [3]. All these issues targeted to user equipment are well addressed on 5G network. The network dynamically detect any kind of malicious actions or node and distinguish it from other network devices. 5G carries out an experiment of the new device introduced to the network in order to determine whether the equipment has been compromised or not.

Network Access

To prevent an authorized network access, 5G implements a strong end user authentication mechanism that prevents intrusion to the targeted network. This is done by use of two techniques, which are applied cryptography algorithm and credential storage. This makes it impossible for an attacker to implement weak cryptography algorithm and access the network as it is the case with earlier generations of network used. An end user credentials therefore ought to be placed in a much secured and highly resistant place.

Mobile core and external networks

This attack takes place through the use of DDoS attacks which amplifies the network signal and targets external networks or equipment via the end user network.  This occurs mostly especially, where users use their own devices to connect onto the network commonly known as bring-your-own-device approach. To prevent this the 5G network implement cross layer fault management, which detects any fault occurrence, diagnose the fault and recover from it. This prevents an intruder from attacking other IP networks from the 5G device [4] .

Conclusion

Its is therefore evident that 5G addresses major security issues that has been experienced in other network generations more effectively thus making 5G network more reliable for enterprise business companies. The network comes with fault tolerance and security mechanisms that prevent intruders from conducting malicious attacks using the 5G connected devices.
