Information systems security issues have usually been considered only after the system has been developed completely, and rarely during its design, coding, testing or deployment. However, the advisability of considering security from the very beginning of the system development has recently begun to be appreciated, and in particular in the system(More)
Requirements engineering is the disciplined and systematic approach to elicit, specify, analyze, commit, validate, and manage requirements while considering user, technical, economic, and business-oriented needs and objectives. It spans the entire lifecycle, often involving distributed teams and supply chains. Tools facilitate consistency and ef ciency in(More)
Requirements engineering (RE) has attracted a great deal of attention from researchers and practitioners in recent years. Requirements engineering education (REE) is therefore an important undertaking if the field is to have professionals who are capable of successfully accomplishing software projects. This increasing interest demands that academia should(More)
In recent years, Web Engineering development projects have grown increasingly complex for and critical to the smooth running of organizations. However, recent studies reveal that a high percentage of these projects fail to attain the quality parameters required by stakeholders. The inadequate consideration of requirements management activities together with(More)
In order to integrate requirements into the current Model-Driven Engineering (MDE) approach, the traditional document-based requirements specification process should be changed into a requirements modelling process. To achieve this we propose a requirements metamodel called REMM (Requirements Engineering MetaModel) which includes the elements that should(More)
The use of ontologies for representing knowledge provides us with organization, communication and reusability. Information security is a serious requirement which must be carefully considered. Concepts and relations managed by any scientific community need to be formally defined and ontological engineering supports their definition. In this paper, the(More)
