Cyber Intelligence and OSINT: Developing Mitigation Techniques Against Cybercrime Threats on Social Media

Open Source Intelligence (OSINT) involve the collection or processes of gathering data and profiling of publicly available private and public sector information sources about individuals and business intelligence purposes. These sources includes internet and other social media platforms such as Facebook, emails, twitters, what’s apps for. Much debate and research has been done on the threats, vulnerabilities and the impact of the use of social media sites but this study is to minimize bias. Objective: To systematic review and synthesis findings on current empirical research topic on cyber intelligence and open source intelligence profiling to identifying both the threats and vulnerabilities on online social networks for mitigation purposes. Methods: A systematic narrative review of research using rigorous searching on online databases. The results were then subjected to review using a quantitative and quality appraisal tool and a narrative synthesis methodology. A theoretical framework was developed for the synthesis using concepts from the literature ‘The Effectiveness of Neighborhood Watch’. A Campbell Systematic Review Results: The systematic search retrieved 18 original research papers investigating and exploring the effects of online social media technologies on open source intelligence concepts. The use of social media were reported as enhancing social cohesion among peers, improving business opportunities as information gets to customers quickly. Safe identity experimentations, OSINT and cyber intelligence social media gathering is especially vital in the modern war on terror. Understanding terrorist network topologies, crime data analysis and mining, countering improvised explosive devices. The study also highlighted potential negative impacts and threats and the effect of social engineering threats in SNSs, threats of social networking and identity crime. Vulnerabilities of HTTP header information and cookies being sent to third-party aggregators as well harmful effects of exposure to threats. Conclusion: The systematic review has revealed extraordinary evidences and contradictory concepts. It has also revealed the underlining research challenges impacting on open source intelligence. Due to the invincibility nature of social media technologies, social media platforms are constantly being used for social, business and intelligence gathering purposes but to ensure proper and advance mitigating circumstance, further research is required to gain situational awareness and appropriate counter measure

Ghana’S Pension Reforms in Perspective: Can the Pension Benefits Provide a House a Real Need of the Retiree?

The Government of Ghana enacted another pension reform in 2008 to establish a three-tier Pension Scheme with the objective of enhancing pension payments, financial independence to the retired worker and also for capital mobilization for national development. The purpose of any policy reforms that seeks to protect vulnerability of people must be significant to address identified inadequacies in a previous one. This paper is very critical of the new pension reform (Act 716) of 2008 as it provides unrealistic benefit to the pensioner to meet vital needs (i. e A HOUSE), a cultural demand, the lack of it, is killing many retirees in Ghana. The significance of the concept of building a house in Ghanaian cultural setting and retirees is discussed extensively. The mortgage industry which the Act or Scheme relies on is also evaluated. The conclusions are very revealing that the mortgage industry in Ghana is very expensive, unaffordable and therefore unreliable to provide any low cost housing to low income earners and many civil servants in Ghana. The paper proposes that a holistic Pension Scheme that is focused and targeted to identified cultural needs must be established. Financial independence as emphasized in the pension reform act is good but myopic and cannot guarantee longevity. Keywords: Pension Reforms, Retirees, House Mortgage

A framework for place based health planning

Place based health planning is an effective approach to health planning with enormous benefits including the use of local characteristics, organisations and partnerships to effectively and efficiently identify and prioritise needs, and develop and deliver programs and services. Despite its inherent advantages, place based health planning has not been extensively used by health professionals, neither has it been given adequate attention in the literature. This article provides a framework to guide and encourage health professionals to use place based health planning. The framework has three main parts, namely needs assessment, program planning and implementation, and covers most aspects of the identification of needs, and the development and delivery of programs and services to address those needs. The article also includes a proposed index of prioritisation to enable health professionals to prioritise needs and improve program and service provision

Population mapping in informal settlements with high-resolution satellite imagery and equitable ground-truth

We propose a generalizable framework for the population estimation of dense, informal settlements in low-income urban areas–so called ’slums’–using high-resolution satellite imagery. Precise population estimates are a crucial factor for efficient resource allocations by government authorities and NGO’s, for instance in medical emergencies. We utilize equitable ground-truth data, which is gathered in collaboration with local communities: Through training and community mapping, the local population contributes their unique domain knowledge, while also maintaining agency over their data. This practice allows us to avoid carrying forward potential biases into the modeling pipeline, which might arise from a less rigorous ground-truthing approach. We contextualize our approach in respect to the ongoing discussion within the machine learning community, aiming to make real-world machine learning applications more inclusive, fair and accountable. Because of the resource intensive ground-truth generation process, our training data is limited. We propose a gridded population estimation model, enabling flexible and customizable spatial resolutions. We test our pipeline on three experimental site in Nigeria, utilizing pre-trained and fine-tune vision networks to overcome data sparsity. Our findings highlight the difficulties of transferring common benchmark models to real-world tasks. We discuss this and propose steps forward

Cybercrime and Risks for Cyber Physical Systems

Cyber Physical Systems (CPS) is the integration of computation and physical systems that make a complete system such as the network, software, embedded systems, and physical components. Major industries such as industrial plants, transport, national grid, and communication systems depend heavily on CPS for financial and economic growth. However, these components may have inherent threats and vulnerabilities on them that may run the risk of being attacked, manipulated or exploited by cyber attackers and commit cybercrimes. Cybercriminals in their quest to bring down these systems may cause disruption of services either for fame, data theft, revenge, political motive, economic war, cyber terrorism, and cyberwar. Therefore, identifying the risks has become imperative in mitigating the cybercrimes. This paper seeks to identify cybercrimes and risks that are associated with a smart grid business application system to determine the motives and intents of the cybercriminal. The paper identified four goals to mitigate the risks: as business value, organizational requirements, threat agent and impact vectors. We used the Analytical Hierarchy Process (AHP) to determine the importance of the goals that contribute to identifying cybercrime and risks in CPS. For the results, a case study is used to identify the threat and vulnerable spots and the prioritized goals are then used to assess the risks using a semi-quantitative approach to determine the net threat level. The results indicate that using the AHP approach to identify cybercrime and risk on CPS provides specific risk mitigation goals

Blood haemoglobin measurement as a predictive indicator for the progression of HIV/AIDS in resource-limited setting

<p>Abstract</p> <p>Background</p> <p>Anaemia is a frequent complication of infection with the human immunodeficiency virus (HIV) and may have multiple causes. The objective of this study was to find out if blood haemoglobin measurement could be used as an indicator for the progression of HIV/AIDS in resource-limited setting.</p> <p>Methods</p> <p>Two hundred and twenty-eight (228) consented People Living with HIV/AIDS (PLWHAs) who were placed in three groups according to their CD4 counts were used in the study. The three groups were those with CD4 counts (1) ≥ 500 mm-³; (2) 200-499 mm-³; and (3) <it><</it>200 mm-³. One hundred (100) sex, age-matched and healthy HIV-seronegative individuals were used as control subjects. Blood haemoglobin, blood haematocrit, Red cell indices which included Mean Cell Volume, Mean Cell Haemoglobin Concentration and Mean Cell Haemoglobin and CD4 count were analysed in all subjects.</p> <p>Results</p> <p>The mean blood haemoglobin concentrations in those with CD4 counts <it><</it>200 mm-³, 200-499 mm-³and ≥ 500 mm-³(8.83 ± 0.22 g/dl, 10.03 ± 0.31 g/dl and 11.3 ± 0.44 g/dl respectively) were significantly lower when compared with the control group (14.29 ± 0.77 g/dl) (<it>p </it>< 0.0001). The mean blood haematocrit levels in those with CD4 counts <it><</it>200 mm-³, 200-499 mm-³and ≥ 500 mm-³(23.53 ± 0.85%, 28.28 ± 0.77% and 33.54 ± 1.35% respectively) were also significantly lower when compared with the control group (41.15 ± 2.15%) (<it>p </it>< 0.0001). The red cell indices were also lower in the subjects when compared with the control group. Using the Pearson's correlation, there was a significant and positive correlation between the blood haemoglobin level and their CD4 counts <it>(</it>r²= 0.1755; <it>p < 0.0001)</it>.</p> <p>Conclusion</p> <p>Anaemia in People Living with HIV/AIDS, if persistent, is associated with substantially decreased survival. From our analysis, there was a decrease in the blood haemoglobin, levels as the HIV infection progressed and our findings are consistent with those of other studies of anaemia as a prognostic factor in HIV infection. Haemoglobin levels could be measured easily where resources for more sophisticated laboratory markers such as viral load or even CD4 lymphocyte count are not available given that measurement of the CD4 lymphocyte count requires flow cytometry, an expensive technique unavailable in many developing countries. Regular measurements could help to determine which patients are at greatest risk of disease progression, allowing these patients to be identified for closer monitoring or therapeutic intervention.</p

Chiefs, changing trust relations and land use planning in Ghana

In Ghana, both statutes and customs designate chiefs as trustees of customary lands. Based on evidence from four case study areas, the study establishes that, some chiefs are redefining their roles as trustees and are increasingly becoming the principal beneficiaries of revenue that accrue from granting of community lands. This drives chiefs to alter land use plans or engage unqualified people to prepare defective ‘land use plans’, that become the basis for guiding the growth of human settlements. These practices contribute to the poor state of planning delivery. Based on the findings, the study recommends that strengthening the capacity of state planning institutions and empowering communities to demand accountability from chiefs are crucial in the quest to improve land use planning delivery in Ghana.Keywords: Accountability, customary land tenure, chiefs, trusteeship, land use plannin

Participation in online activation (#) campaigns: A look at the drivers in an African setting

Online brand activation is in vogue and has been used by several brand giants (e.g. Apple, Adidas, etc.) to create viral campaigns that invite consumers to join brand-initiated conversations. The opportunities therein for brand visibility and customer engagement are immense. However, to leverage it, brand communicators must first understand the characteristics of persons most likely to participate in it and target them, a question that is yet to be addressed in the budding literature on the subject. For brand communicators, particularly in developing economies such as Ghana where low internet penetration levels and high associated costs may hinder participation, this is a critical gap in their quest to justify the relevance of online activations to boost brand visibility and customer engagement. This study sought to address this gap by testing a model of the drivers of participation in online activations using a consumer survey (N = 278), set in a recent online activation campaign in Ghana. The findings suggest that persons who trust the activated brand would be inclined to participate in it, suggesting the need for brand communicators to first work on building trust. The study also finds that individuals who are susceptible to interpersonal influence are less likely to participate in such activations. Possible explanations for this are explored in the study along with their implications

A Linear Model for the Collection of Institutional Plastic Wastes in Ghana: A Case of the Council for Scientific and Industrial Research-Institute of Industrial Research (CSIR-IIR)

The collection of plastic wastes (p-wastes) in Ghana has received attention in recent years. However, there are persistent disposal of the p-wastes into the environment with associated costs to life on land, sea and in the air. The collection of domestic and industrial p-wastes, con­tributes to the national recycling rates whilst the intuitional p-wastes lags behind with minimal backing and contributions. For this reason, the study sought to explore the structures required to improve plastic wastes collection at the workplace to enhance recycling and greener jobs. In the pilot study, workers at the CSIR-IIR were interviewed to determine a premier model for the efficient collection of the institutional plastic wastes. The methodology included random administration and retrieval of questionnaires, coding and tallying of survey responses, and the processing of generated data. The research questions bordered on the most generated solid and plastic wastes, the preferred mode of collection and the expected gains to the institution. Quali­tatively, plastic wastes were the most generated solid wastes. Purified water sachets formed the bulk of generated p-wastes. Source sorting was favoured over the mixed mode of collecting the solid wastes, which will contribute to income generation and a linear collection model.
