Proposing a secure component-based-application logic and system’s integration testing approach

Software engineering moved from traditional methods of software enterprise applications to com-ponent based development for distributed system’s applications. This new era has grown up forlast few years, with component-based methods, for design and rapid development of systems, butfact is that , deployment of all secure software features of technology into practical e-commercedistributed systems are higher rated target for intruders. Although most of research has been con-ducted on web application services that use a large share of the present software, but on the otherside Component Based Software in the middle tier ,which rapidly develops application logic, alsoopen security breaching opportunities .This research paper focus on a burning issue for researchersand scientists ,a weakest link in component based distributed system, logical attacks, that cannotbe detected with any intrusion detection system within the middle tier e-commerce distributed ap-plications. We proposed An Approach of Secure Designing application logic for distributed system,while dealing with logically vulnerability issue

A design recording framework to facilitate knowledge sharing in collaborative software engineering

This paper describes an environment that allows a development team to share knowledge about software artefacts by recording decisions and rationales as well as supporting the team in formulating and maintaining design constraints. It explores the use of multi-dimensional design spaces for capturing various issues arising during development and presenting this meta-information using a network of views. It describes a framework to underlie the collaborative environment and shows the supporting architecture and its implementation. It addresses how the artefacts and their meta-information are captured in a non-invasive way and shows how an artefact repository is embedded to store and manage the artefacts

The Value Proposition of Service-Oriented Architecture

The author of this thesis evaluates Service-Oriented Architecture (SOA) design and implementation strategies. The purpose is to provide the reader with the definition of Service-Oriented Architecture. This report discusses: (1) The definition of Service-Oriented Architecture, (2) The problems solved by Service-Oriented Architecture, (3) Application of design principles to achieve Service-Oriented Architecture. As a result of this investigation, Service-Oriented Architecture is a design style that is fundamentally about sharing and reuse of functionality across diverse applications, so that organizations can quickly adapt to changing business requirements while increasing IT asset reuse and minimizing integration and development costs

Web Based Candidate Assessment System

Devplex Technologies Limited is a privately owned company based in Galway Ireland. They have been operating for over two years and currently undertake contract projects for the travel and financial industries. The projects are varied and a wide range of skills are necessary. Devplex Technologies are currently undergoing expansion and intend to hire a number of new employees with varying levels of experience. Devplex Technologies also employ a high number of contractors, with varying skills and contract periods range from one month to twenty four months. The current technical leaders are all very busy with project work. The human resource manager actively advertises positions on both the internet and local newspapers which results in a large number of responses. It is difficult to sort through all the applicants as a high level of technical knowledge is required to vet them. When the human resource (HR) manager selects a number of potential candidates from the vetted curriculum vitas, phone interviews are conducted. The HR manger pools questions which have been submitted from employees who have experience in the relevant technologies. The HR manager has to decide if the candidate\u27s answers are satisfactory for the questions. The most successful candidates are then requested to attend a formal interview. Once a candidate presents for interview they are requested to take a short 10 minute written exam where they are asked to answer five questions relevant to the position they are applying for. Regardless of the outcome of the exam the candidate then proceeds to a formal interview where two or more employees from Devplex Technology interview the candidate and take note of their findings. Once the candidate has left the interview, the HR manager and interviewers meet to discuss the exam and interview and decide if the candidate should be brought for a second interview. If the candidate\u27s second interview is successful the candidate is hired. Devplex Technology interviews a high number of unsuccessful candidates resulting in wasted time and effort. Sometimes employees who are not technically strong enough can be erroneously hired. Devplex Technology wishes to reduce this workload and hire more suitable people by implementing an enterprise based candidate assessment system. The system should allow the remote assessment of potential candidates. It should also allow the HR manager to easily retrieve questions and answers on a selected topic. The system should test the candidates only on subjects which apply to the role they are hired for, the questions should progressively get harder as the candidate gets more questions correct, this will allow for a truly strong candidate achieve the highest score. The overall aim of the system is to reduce workload and help find the best possible candidate for Devplex Technologies

An Architecture for Information Commerce Systems

The increasing use of the Internet in business and commerce has created a number of new business opportunities and the need for supporting models and platforms. One of these opportunities is information commerce (i-commerce), a special case of ecommerce focused on the purchase and sale of information as a commodity. In this paper we present an architecture for i-commerce systems using OPELIX (Open Personalized Electronic Information Commerce System) [11] as an example. OPELIX provides an open information commerce platform that enables enterprises to produce, sell, deliver, and manage information products and related services over the Internet. We focus on the notion of information marketplace, a virtual location that enables i-commerce, describe the business and domain model for an information marketplace, and discuss the role of intermediaries in this environment. The domain model is used as the basis for the software architecture of the OPELIX system. We discuss the characteristics of the OPELIX architecture and compare our approach to related work in the field

Analysis of Web Services on J2EE Application Servers

The Internet became a standard way of exchanging business data between B2B and B2C applications and with this came the need for providing various services on the web instead of just static text and images. Web services are a new type of services offered via the web that aid in the creation of globally distributed applications. Web services are enhanced e-business applications that are easier to advertise and easier to discover on the Internet because of their flexibility and uniformity. In a real life scenario it is highly difficult to decide which J2EE application server to go for when deploying a enterprise web service. This thesis analyzes the various ways by which web services can be developed & deployed. Underlying protocols and crucial issues like EAI (enterprise application integration), asynchronous messaging, Registry tModel architecture etc have been considered in this research. This paper presents a report by analyzing what various J2EE application servers provide by doing a case study and by developing applications to test functionality
