It is based on the fraud diamond which comprises four components: pressure (i.e. motive), opportunity, capability and rationalisation. In general, it has been found that a criminal must have the motive and opportunity to commit a crime. However, the criminal must also have the capability to commit crime particularly in the cybercrime domain. Furthermore, criminals tend to rationalise (i.e. excuse) their crimes. The model presented here involves leveraging the fraud diamond to predict and prevent insider threats. Typically insider threat prediction and prevention models tend to overlook the privacy concerns of insiders. Hence the deployment of the model involves gathering information about the insider's possible intent within a privacy-preserving context. This will help to identify high risk insider threats while balancing privacy concerns.","PeriodicalId":221523,"journal":{"name":"2015 Annual Global Online Conference on Information and Computer Technology (GOCICT)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115667871","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}

Equally important is the use of methodologies for software design. In just over six decades, we have seen the progress of software design from an amorphous set of informal methodologies to structured techniques, formal methodologies, and object-oriented methodologies. In the area of object-oriented methodologies (OOM), the unified modeling language (UML) has made a significant contribution in defining a set of methodologies that can be applied to any software engineering effort. This paper draws on the UML methodologies and proposes three methodologies that could add richness and additional flexibility to the software engineering experience. They are system topology charts, object/entity specification grid, and the extended operation specification. The system topology charts include an information topology chart (ITC) that presents the object types and/or information entities in the way they will be managed in the software system, and a user interface topology chart (UITC) that presents operations the way they will appear in the system. The object/entity specification grid (O/ESG) adopts the conventions of the UML class diagram, but expands it to include additional critical information that lead to better software construction. The extended operation specification (EOS) embraces the UML guidelines for the activity diagram, but is flexible enough to include other techniques such as pseudo-code, Warnier-Orr diagram, and collaboration diagram. It also allows for the specification of other critical information not covered in these standard techniques.","PeriodicalId":221523,"journal":{"name":"2015 Annual Global Online Conference on Information and Computer Technology (GOCICT)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124903677","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}

However secure and reliable dissemination of data over a lossy wireless network is challenging due to security attacks and network dynamics. The current proposed schemes require high computational capability of the devices which may not be feasible in most of hand held receivers. Furthermore, in many scenarios, data may need to be relayed via multiple links before reaching to the end users posing potential data breach. Our proposed scheme alleviates computational requirements along with transmission overhead by exploiting the new transmission technique, namely network coding. Our propose scheme utilizes a hierarchical key structure for efficient security key management. In addition, we utilize the null space of network coding to enable secure relay of data via multiple hops. Also, by exploiting network coding, our scheme don' require cooperation among the relay nodes which significantly reduce the communication overhead. Our analysis results show that under some condition, our propose scheme can save up to 50% transmission bandwidth compared with the traditional approach where users share a common group key. We also show that our proposed scheme can achieve high security under relay attacks. The proposed scheme is also efficient with light computation that would be feasible for mobile devices.","PeriodicalId":221523,"journal":{"name":"2015 Annual Global Online Conference on Information and Computer Technology (GOCICT)","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134126503","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}

Although the number of government sites has increased rapidly in the past few years, their ultimate success will largely depend on their accessibility, quality and performance. This paper reports the results of an evaluative study of 19 e-government websites and portals using a common set of Web diagnostic engines. The findings reveal that none of the sites evaluated meet the recommended Priority AA conformance level. A number of accessibility, quality, and performance weaknesses were identified. Majority of the sites assessed fail to comply with perceivable, operable, understandable, and robust principles of the Web Content Accessibility Guidelines (WCAG). Several non-compliance errors were found on the websites. The page load time for most sites falls far below the acceptable level, spelling errors and bad links were also found. Significant work needs to be done in order to make these websites examples of best practice e-government sites.","PeriodicalId":221523,"journal":{"name":"2015 Annual Global Online Conference on Information and Computer Technology (GOCICT)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132539155","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}
