(Great Zimbabwe University, 2025) Njodzi Ranganai; Magoso Mercy Nyasha; Zivanai Lemias; Sambo Paul; Muwani Tendai Shelton
This paper explores Zimbabwe’s public sector AI readiness and preparedness. There is an urgent need to find out the drivers of preparedness since AI is becoming more mainstream in the hands of governments in an attempt to increase governance and service delivery. The methods that the authors use are a combination of mixed approaches that include quantitative surveys of different organizations operating in the public sector and qualitative interviews with some of the stakeholders in the area of focus. The key elements of AI preparation such as skills of the work force, organizational culture, data and technological infrastructure are defined and measured by authors in quantifiable terms. The results indicate that the degree of preparedness in the firms has considerable differences that can be attributed to a combination of diverse factors including the opportunity to train and resource allocation. The research paper provides the urgent need of the customized plans of optimizing the AI application in the state sector in Zimbabwe. In addition to equipping policymakers and government administrators with operational knowledge enabled to achieve innovation and enhance governance, this study may be applied to create successful implementation strategies of AI, since the study may offer an effective metrics framework. Finally, to make sure that the AI technology could be successfully adopted by the public sector organizations to promote the services delivery and communication with citizens, AI Metrics on public sectors as recommended by the authors.

The 4th Industrial Revolution has also been triggered by the high intensity of artificial intelligence (AI), Internet of Things (IoT), and big data, which is bringing a revolution in knowledge work, but also posing unprecedented cybersecurity threats. Even with technological advancement, organizations are finding it difficult to ensure that sensitive intellectual property is not compromised by advanced cyber attacks, which is also a cause of concern to data integrity, privacy and operational resilience. This study project was intended to answer the following questions: How do new technologies in the 4th Industrial Revolution transform the problem of cybersecurity in knowledge-based industries? How can organizations ensure that they reduce cyber risks to embrace digital transformation? How is policy frameworks and the preparedness of the workforce contributing to enhancing cyber defenses? This paper was a crucial point of intersection between cybersecurity and the 4th Industrial Revolution, which provided a glimpse into how knowledge work can be secured in the age of hyperconnectivity. The research establishes certain gaps in IoT and cloud governance and suggests a hybrid system comprising of NIST CSF and Zero Trust principles in knowledge-intensive systems. This paper will use a mixed-methodology in order to assess cybersecurity strategies. It combines case studies, analyses of breach patterns using quantitative data, interviews with experts, and a literature review and interprets the findings in terms of the NIST Cybersecurity Framework, Zero Trust Architecture, and human-centric security models. The results showed that AI and automation bring defensive and attack types; those companies that are adaptive and layered in their security measures also exhibit greater resilience. Regulatory loopholes and lack of skills also negatively impact successful management of cyber risks, and coordinative structures (public-private partnerships) improve the sharing of threat intelligence. Due to the redefinition of knowledge work provided by the 4th Industrial Revolution, active cybersecurity strategies should also transform. This study emphasizes the importance of agile policies, upskilling of work forces, and integrating technology into security to tap all the potential of the revolution in a secure way.
From Policy to Practice: Evaluation of Telecom Cybersecurity Regulation and Capacity in Southern Africa.
(Great Zimbabwe University, 2025) Njodzi Ranganai; Magoso Mercy Nyasha; Chidoko Clainos; Sambo Paul; Mushamainza Zvishamiso; Zivanai Lemias
The authors inquired on the effectiveness of cybersecurity controls and regulations within the telecommunications industry in Southern Africa and expounded the strengths and weaknesses of the effective governance frameworks. Complex cyber threats are much targeted to digital technology infrastructure and resilience is important to provide economic stability, consumer protection as well as national security. The investigation used a mixed method design that includes the surveys of telecom operators, policy documents study, and interviews with regulators and industry actors, the research also determines some crucial tendencies. The findings of the research show the inconsistency of policy implementation in a country, disordered compliance with regulations by telecom operator and lack of enforcement frameworks on a state level. Moreover, the absence of cross border cooperation, resource insufficiency, and the dissimilarity of the institution capabilities prevent the mutuality of cybersecurity activities. The absence of user consciousness that persists also reduces the strength of resilience as the users are still under the threat of phishing, mobile money attacks and SIM-swap fraud. The positive advances in this study also include the emergence of national Computer emergency response teams (CERT), the adoption and congruency of policies with global standards and the increasing political intent to prevent the cyber threat. To sum up, it is important to note that despite the significant improvement, the telecom industry in the region is at the lowest level of cybersecurity. The paper takes into account standardization of cybersecurity at regional level, increased regulatory controls, capacity-building and sensitization efforts through skills and awareness gimmicks, and regional integration to produce a healthier, more sensitive and secure telecom environment in Southern Africa.
