Dissertation (MSc Information Technology)The aim of this study was to determine factors that affect the security and operation performance into the Management of Land Information System (MOLIS) at the Ministry of Land, Housing and Human Settlement Development (MLHHSD). The researcher used the case study design; whereby both qualitative and quantitative approaches were used for gathering data for this study. The study investigated on the potential security issues and operation details of the network, hosts/servers, and applications such as MOLIS. Questionnaires were used for gathering important details from ICT experts, system users as well as customers. The observation method was used for collecting potential details from system users as well as system operation behaviours. Moreover, the researcher employed the use of security vulnerability scanners such as; GFI LanGuard 2012 and Nmap 7.01 for the collection of potential security technical details of network, system and computers. The Statistical Package for Social Sciences (SPSS) version 20 and Microsoft excel were used during analysis for the data, whereby, both qualitative and quantitative analysis methods were used. The use of descriptive statistics method was employed in order to determine the different percentages of the respondents. Then, qualitative data was analyzed with the use of content analysis to get meaningful information. Findings from the study reveal several factors that were contributing in security and operation performance degradation in MOLIS; whereby factors such as weak system administration, system design flaws, poor system configurations, system backdoor activities, bureaucracy, corruption, were some of the mentioned factors associated to. Moreover, the study used Adobe vulnerability severity rating for categorization and assessment for the potential vulnerability revealed during the study.
