To connect to a wireless network a user needs to be authenticated by and be associated with an access point. Management frames and control frames are used for authentication, association and giving a user access to the wireless network. Management frames and control frames are sent in clear text and can expose the wireless network to security attacks such as media access control spoofing and session hijacking attacks. An attacker with the packet sniffer software can intercept packets and extract Media Access Control addresses of the access point or other users. MAC address is used to associate a client with the access point in wireless networks. An attacker can use a spoofed Media Access Control address of the real access point to disconnect the legitimate users from the network and takeover any existing TCP session that has already been established. Since the legitimate user is already authenticated in the network, an attacker with the spoofed MAC address will not require authentication. Such an exploitation of a valid computer session to gain unauthorized access to information or services through a network is referred to as session hijacking attack. There are proposed methods for dealing with MAC address spoofing. Some methods produce lots of false positives and false negatives while others require a lot of infrastructural overhead as well as computational overhead. In this study some of the existing MAC addresses spoofing detection and prevention methods are reviewed, with strengths and weaknesses analysed. Factors considered in the analysis include reliability and robustness of the methods, and performance in terms of computational overhead and efficiency.","PeriodicalId":326074,"journal":{"name":"2016 IST-Africa Week Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123518835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been used for quickly solving a myriad of social and business challenges by tapping into the diversity of the unknown crowd. Nevertheless, there are still a number of research challenges that are found in various microtasking initiatives, such as lack of user profiling, quality of task submissions, poor task design and assignment, ambiguous task assessments, and lack of diverse platforms to cater for the needs of differently skilled crowds. Most prominent microtasking platforms do not consider or even exploit the profile of the crowd in improving task design, assignment, and eventually quality of completed microtasks. In this paper, the objective was to explore the design and evaluation of a conceptual approach that could be implemented in microtasking environments for purposes of improving task assignments and eventually quality. A design science research methodology was adopted to build the proposed artefact, which was evaluated for relevance using comparative analysis and crowdsourcing metrics. The results suggest that exploiting micro workers' profiles could improve task design, assignment, assessment, and ultimately quality. However, stakeholders' awareness of effective microtasking approaches still requires research attention.","PeriodicalId":326074,"journal":{"name":"2016 IST-Africa Week Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121951671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

e-Government development in Sub-Saharan Africa (SSA): Relationship with macro level indices and possible implications 撒哈拉以南非洲的电子政务发展:与宏观指标的关系及其可能的影响

However, there are still great disparities in the level of e-government development between the developed and developing worlds, with Sub-Saharan Africa (SSA) lagging behind all other regions. The reason for these disparities has so far been attributed to differences in national income; nonetheless, some resource-poor countries have succeeded to make great strides in e-government development. As such, there has been a call to examine other indicators of e-government development, since national income alone does not paint a detailed picture. In this light, this study examined a total of six indicators (corruption, gender equality, population age, national income, cybersecurity, and innovation) that are believed to influence e-government development using SSA as the case study. Macro-level indices were used to capture country level data from 49 SSA countries. The findings indicated that all the factors significantly influenced e-government development in SSA. The paper culminates with a discussion of the possible implications of the findings.","PeriodicalId":326074,"journal":{"name":"2016 IST-Africa Week Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121668413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
