Confronting The Challenges of Insecurity in Ondo State: The Role of Geospatial Surveillance and Mapping

The situation of insecurity in Nigeria has ignited different levels of government to form their security networks. One such effort was made by the Ondo State Government by creating Amotekun Security Network for Ondo State. This is to improve the security of life and property of people in the state. This was a result of the persistent siege laid by marauders on the highways and farms in the state. There is no doubt about the good intensions of the Governor which he has backed up with action in the inauguration of Amotekun Security Network for Ondo State. However, the trend of combatting crime and terrorism in this 21st century has gone more sophisticated to the extent that conventional security architecture has become grossly inadequate, thus the need to upgrade security architecture to the level whereby security system and the personnel can combat the crime and even nip it in the bud before attacks. This can only be possible by complementing the conventional structure with available geospatial apparatus for security surveillance in confronting the challenges of insecurity not only in Ondo State but Nigeria at large. This paper thus appraises the challenges of insecurity in Ondo State and the role of geospatial surveillance and mapping. The paper was based on a review of literature and qualitative technique of analysis. This paper was structured into background information about Ondo State, an overview of security challenges in Nigeria with attention on Ondo State, the take-off of Ondo State Security Network Agency called Amotekun, and highlights on geospatial technology solutions for security surveillance in confronting insecurity challenges. This paper thus concludes that insecurity in Ondo State and the entire Nigeria could be curbed if security network can be complemented with geospatial surveillance and mapping technique.

Overview of 5G Security Challenges and Solutions

5G networks will use novel technological concepts to meet the requirements of broadband access everywhere, high user and device mobility, and connectivity of massive number of devices (e.g., the Internet of Things) in an ultra-reliable and affordable way. Software defined networking and network functions virtualization leveraging the advances in cloud computing such as mobile edge computing are the most sought out technologies to meet these requirements. However, securely using these technologies and providing user privacy in future wireless networks are the new concerns. Therefore, this article provides an overview of the security challenges in clouds, software defined networking, and network functions virtualization, and the challenges of user privacy. Henceforth, this article presents solutions to these challenges and future directions for secure 5G systems.

A decade of security research in ubiquitous computing: results of a systematic literature review

Purpose Ever since Mark Weiser coined the term “ubiquitous computing” (ubicomp) in 1988, there has been a general interest in proposing various solutions that would support his vision. However, attacks targeting devices and services of a ubicomp environment have demonstrated not only different privacy issues, but also a risk of endangering user’s life (e.g. by modifying medical sensor readings). Thus, the aim of this paper is to provide a comprehensive overview of security challenges of ubicomp environments and the corresponding countermeasures proposed over the past decade. Design/methodology/approach The results of this paper are based on a literature review method originally used in evidence-based medicine called systematic literature review (SLR), which identifies, filters, classifies and summarizes the findings. Findings Starting from the bibliometric results that clearly show an increasing interest in the topic of ubicomp security worldwide, the findings reveal specific types of attacks and vulnerabilities that have motivated the research over the past decade. This review describes most commonly proposed countermeasures – context-aware access control and authentication mechanisms, cryptographic protocols that account for device’s resource constraints, privacy-preserving mechanisms, and trust mechanisms for wireless ad hoc and sensor networks. Originality/value To the best of our knowledge, this is the first SLR on security challenges in ubicomp. The findings should serve as a reference to an extensive list of scientific contributions, as well as a guiding point for the researchers’ novel to the security research in ubicomp.

Migrating from Closed Source Software to OSS–Security Issues and Challenges

Open source software (OSS) allows users and developers to, amongst others, study, modify and redistribute the source code. At the other end of the spectrum, closed source software (CSS – the antonym of OSS) disallows users and developers to access and modify any source code. This paper presents an overview of the migration from closed source systems (CSS) to open source systems (OSS) with respect to Security Issues and Challenges. The paper proposes a Model to address such challenges. The various OSS initiatives undergone by different national governments are highlighted. A comparison of OSS security and CSS security aspects, and an overview of security challenges during migrations to OSS are presented. On the strength of these comparisons, and using summative content analysis, a model to address security challenges during migrations to OSS is proposed. The model is developed through enhancements of previous models aimed at addressing security threats and protecting sensitive information during system migrations.
