The results clearly indicate a continued growth in research interest with the most significant in 2022. These results are an indication that research in the field of IoT security protocols is still in its infancy in the African continent compared to other continents. Hence, African countries still have the opportunity to do more research in the field of IoT security protocols. Hence, identifying and finding ways to fill these gaps is the main contribution of this paper.
More work is need in securing IoT systems through continued protocol development including standardized guidelines and can advance more resilience in securing the operations of the devices.
The findings of this study will be significant and instructive, giving the community and industry additional information and a better understanding of the state of research today and its development trends. The current study can promote new applications, advance Internet of Things security protocols research, and suggest new channels for disseminating knowledge in the area

CONCLUSIONS AND FUTURE WORK
To better understand the research trends on IoT security protocols, a review study that entailed assessing the status of the existing research in the field of IoT security protocols was conducted. This was achieved through a bibliometric analysis of scientific publications (i.e. articles, books, book chapters, and conference papers) for the period between 2016 and 2022. It emerged that IoT security protocols are an active ongoing research field with American and Asian affiliations (institutions) being the most contributors in terms of producing research papers in this field. In addition, America and Asia are identified to be the top two continents dominating in terms of publications and are the most prominent in the collaboration network. It has also emerged that Africa is still lagging behind compared to the two mentioned continents, namely America and Asia. Nevertheless, some kind of effort has been noted from the African continent. For example, the study findings revealed that Tunisia is the only collaborative country in Africa that shows collaboration with Saudi Arabia.

Keywords co-occurrence network
Keywords co-occurrence network is illustrated in three clusters. A keyword co-occurrence network is about identifying the appearance of the most frequently used keywords in a document such as a research paper, an article, a book, etc. In other words, it is about checking the number of times the keywords appear in a document during bibliometric analysis. In the context of this review study, a maximum of 50 keywords were extracted from bibliometrix, with 3 as the minimum number of occurrences. Therefore, in this review study, the keywords were separated into 3 clusters and these 3 clusters were further analysed by means of the strength association method.
Cluster 1 (red) has the most keywords related to IoT device security (e.g., authentication, blockchain, network security, public key cryptography), whereas Cluster 2 (blue) has words related to IoT and Data security (Internet of Things, network security, cyber-attacks, cybersecurity, security, security protocols), and Cluster 3 (purple) has keywords related to cyber-attacks (denial-of-service-attack, malware, distributed denial of service). The most common keywords are the internet of things, network security, and cyber-attacks.

The overall objective of IoT network security is to offer protection by preserving integrity, availability, and confidentiality of system resources.
IoT architecture allows diverse connectivity platforms and technologies such as the Radio-Frequency Identification (RFID), Wireless Sensor Networks (WSN), Machine-to-machine; making it more challenging in the provision of reliable and secure solutions.
Depending on the nature of network topologies, each connected device would work with some protocol such as UDP or TCP. However, it is through these protocols that vulnerabilities can be exploited by threat actors.
Although industry experts develop specific protocols to address these vulnerabilities, there are still inadequate in dealing with ever emerging security threats. Examples of specific protocols developed and being used are OS4I, Bluetooth Low Energy (BLE), Zigbee, Z-Wave, Wireless Hart, Sigfox and LoRaWAN.

The following guidelines are recommended as a way to secure IoT systems:
• Account for all the data that is being collected and stored within the environment
• Security configuration should be made to each and every device connected to the network
• Organisations should always assume compromise at some stage in the operations of IoT systems.
• Apply physical security to each and every device.
However, despite guidelines, there are still new cyber-attacks that are emerging everyday.
Clearly, IoT has become ubiquitous and pervasive within most of our daily lives such as home, cars, hospitals etc. although it has come with associated security and privacy issues.
Despite many efforts, it is interesting to note that there is still lack of standardised security and privacy guidelines for reliable and secure utilisation of IoT systems and services.

The underlying technological nature of IoT devices may allow security vulnerabilities when performing the following activities
• Gathering of abundant data – IoT devices and sensors normally collect large scale data, detailed in nature within their environments and users. This data, of which some of it is necessary for their own operation is vulnerable to attacks if not properly secured.
• Connection of virtual and physical environments – A greater impact on attacks is created due to shortened distance created between the virtual and physical systems.
• Creation of complex environments – the complexity and dynamic interactions within the environment in which a single IoT operates increases the attack surface.
• Centralization of architecture – the traditional approach that requires IoT devices and sensors to collect data and send to a base station can have a detrimental effect of security.

The rate at which cyber-attacks are exploiting IoT device vulnerabilities has been increasing while the IoT services remain pervasive.
In order to secure data and mitigate threats, a number of protocols, technologies, tools and techniques are involved.
Hence, a constant review and analysis of effectiveness of IoT associated security protocols is critical for their secure operation.
There has been limited comparative studies on analysis of the research trends on IoT security protocols.
The main objective of this paper was to carry out a systematic bibliometric analysis to identify emerging trends in finding evidence about security protocols designed to support IoT devices from cyber-attacks and to accomplish this goal, a systematic literature review of articles about publisher’s performance, collaboration patterns, and research constituents was conducted, along with an investigation of the intellectual structure of Internet of Things security protocols in the existing literature
Further, in realising this, the study categorised and visualised collected research output documents with respect to annual scientific production, top five sources with the highest number of citations, most relevant authors, keywords used and sources. the analysis also considered top countries with their most prolific affiliations including collaborative work ensured.

The upsurge of the fourth industrial revolution brings about an emergence of cloud-based technologies such as the Internet of Things (IoT). By design, these devices and systems are bound to operate in complex environments that require secure assurances at the same time the need for mechanisms to achieve resilience in an event of threats or attacks.
IoTs have become like everyday objects used in many operational areas such as personal wellness tracking, home, or vehicle automation etc. and are rapidly increasing worldwide.
IoT consists of interconnected devices or machines that have the capability of transferring data on a communication network without much of physical human intervention.
However, Traditional defense strategies are failing to successfully counter emerging cloud-based threats and attacks.
We have also observed that little attention has been paid to finding evidence about security protocols designed to support IoT devices from cyber-attacks.
To accomplish this, however, would require a literature review study on current trends, concerns, and ongoing research in the field of Internet of Things security protocols.
This is the gap that this study is aimed to fill through an analysis of scientific paper publications.
