## 3 Security and Privacy of Computing Paradigms
### Edge-Related Aspects  
Since Cloud computing's performance dropped greatly caused by various factors, including the growing number of nodes, Edge computing has provided a significant paradigm shift. Edge Computing is observed as an innovation because it can carry applications with its new technological capabilities in shared computing while also performing information processing right at the point of need, without transporting the data to the Cloud. Users overall have a better feeling when data are processed close to them, improving their response time. This is made possible thanks to the computation that is directly carried out at the nodes of distributed equipment [62].  
Fifth Generation (5G) networks are taking over many areas and operations of our daily activities [63]. Edge computing is undeniably the pivot of all these changes being a part of 5G network, making it vital in terms of smaller resource-constrained devices and how they interact. Edge Computing shows a relationship with heterogeneous equipment and several cross-connected networks. The inter-connectivity of these Edge supporting technologies exposes it to the most concerning aspect of any device, technology, network, and above all, organizations, which is safety. The threats involved here cannot be taken for granted, and this now led us to the subject matter, security, and privacy in Edge Computing. With computation at the node of Edge devices, other security circumstances will show up and still require continuous research work for improvements [64].  
In Edge, the chances for imminent threats and attacks are very likely because of the decentralized design of the Edge computing system, even though the processing of information at the nodes offers some security and privacy protection. Smart devices also expose security issues and dangerous malware to Edge computing. The structure of Edge computing cannot adequately support the mechanisms for securing and protecting information. This, therefore, implies that the complexity of this Edge node at the network leaves the data very exposed and hard to secure.  
Despite the growing nature of Edge computing technologies, its security and privacy development remain a continuous process and tells why there exist not so many research findings. Researchers and other academics globally have been putting every effort in performing relevant research work to develop countermeasures to improve the security and privacy of Edge systems. Different simple mobile Edge computing methods were used for carrying out security checks, presentation of an overall security and protection scheme with proposals from the research work done. The Edge security findings do present a relevant citation from a theoretical approach. As mentioned previously, the existing known issues in this work relating to Edge computing information security and privacy are partitioned into four separate parts [65]: Access Control, Identity Authentication, Information Security, and Privacy Protection. Based on the focused theme of this work, \"Security and Privacy Aspects\", we shall be looking more into only Information security and data protection.
