    Integrated Intrusion Detection Security System Model
    (Strathmore university, 2014-06) Katana, Mwatete Dominic; Ateya, Ismail Lukandu; Orero, Joseph Onderi; Kiraka, Ruth
    Organizations are investing heavily in security systems to secure their premises and assets . In an effort to enhance security, organizations have turned to the adoption of Intrusion Detection Systems. lDSs have improved in efficiency and effectiveness in the way they detect and respond to intrusions. They are moving from manual detection of intrusions to automated detection of intrusions. Most of the existing IDSs are stand-alone hence making it difficult to associate intrusions. They also cannot offer a complete organization security hence needs to be integrated with other system security components. Exploratory research design was adopted in coming up with the solution due to the nature of the study. Data was collected through questionnaires, journals, theses and observation of existing security systems. The collected data was organized and analyzed using SPSS tool. The finding and analysis of the data were presented in descriptive statistics where tables, percentage and charts were used. The model developed was informed by the research findings that showed most organizations secure their premises and assets but lack a standardized model to integrate different security system components. An Integrated Intrusion Detection Security System Model provides a standard for developing systems to integrate different security system components in an organization. The integration of heterogeneous IDSs and different security system components improves the security performance as this associates different security system components to share intrusion information.

    Software as a Service Application Evaluation Framework Addressing Configurability
    (Strathmore university, 2014-06) Owiti, Yvonne Mwajuma; Marwanga (Dr.), Reuben; Orero, Joseph Onderi; Kiraka, Ruth
    Software as a Service (SaaS) is a global technology trend to watch as adoption keeps soaring, yet configurability concerns linger. SaaS users may make uninformed decisions when choosing an application by failing to factor in configurability limitations. In view of the frameworks reviewed by the researcher, there is no framework for SaaS applications that can be used to evaluate a system that meets users' requirements with configurability limitations addressed. In an attempt to determine the specific configurability limitations currently experienced by SaaS users in Kenya, the study listed sixteen (16) configurability items. Fifty (50) percent of them were reported to have configurability limitations. These include; custom fields' definition, data export, in-house application integration, domain name modification, listing report pagination, custom fields' behavior modification, plug-in installation and dashboard customization. SaaS industry is yet to mature the processes and models of dealing with these configurability concerns. This means that configurability limitations will still linger. SaaS users therefore need to be armed with the knowledge of such weaknesses ill order to source wisely for a SaaS application. An evaluation framework was proposed by the researcher. This was validated by two IT managers. The feedback from the validation process (usefulness -100%, effectiveness - 100%, completeness- 90% and accuracy 95%) was used to further enhance the framework. This framework will help prospective SaaS users make the right choices during sourcing.

    User interface design standardization matrix for mobile applications
    (Strathmore University, 2014-07) Muiruri, Chege Mark Brian; Omwenga, Vincent O; Orero, Joseph Onderi; Kiraka, Ruth
    Mobile applications are becoming increasingly popular in the modern setting due to mass adoption of mobile devices and associated technology. However, mobile applications development has been faced by many challenges specifically in user interface design. Recent studies have shown that user interfaces for mobile applications are neglected and rarely meet user needs and expectations. This is largely due to a combination of factors such lack of user participation, programming errors and crossplatform consistency. This paper adopts an exploratory research design in its attempt to provide a solution to the aforementioned problem which is attributed to lack of standardization in user interface design for mobile applications. In an attempt to address this problem, this paper analyzed the features and examined the principles of user interface design for mobile-applications. This-paper proposes a user interface design-standardization matrix as the solutions which should guide designers of user interfaces for mobile applications. The implementation of the standardization matrix is done at the design stage of the user interface and after the interface has been designed. This enables designers to compare the expected design and the actual user interface design. Adoption of this matrix by designers will lead to better quality and superior user interface designs which will in turn improve the usability of mobile applications and user experience. Therefore, the basis of this research is user interface design for mobile applications which is modeled around user interface design features and principles as the key components.
