Nowadays, mostly security solutions are mainly focused on how to defend against various threats, including insider threats and outsider threats, instead of trying to solve security issues from their sources. In this paper, a security requirements engineering process is presented for security requirements elicitation and analysis. And the proposed process will deal with the security requirements...

Software systems of today are characterized by the increasing size, complexity, distribution and heterogeneity. Understanding and supporting the interaction between software requirements and architectures remains one of the challenging problems in software engineering research. In this paper we present an approach for integration of system requirements and software architectures within the cont...

This tutorial describes the activities and work products that contribute to the specification and validation of the software requirements of a system. Although requirements practices are closely related to specific software development life cycle models, the general activities described in this paper are common to most process models. The activities of elicitation, analysis, specification, vali...

The requirements elicited from stakeholders suffer from various afflictions, including informality, incompleteness, ambiguity, vagueness, inconsistencies, and more. It is the task of requirements engineering pREq processes to derive from these an eligible (formal, complete enough, unambiguous, consistent, measurable, satisfiable, modifiable and traceable) requirements specification that truly c...

In requirements engineering, there are several approaches for requirements modeling such as goal-oriented, aspect-driven, and system requirements modeling. In practice, companies often customize a given approach to their specific needs. Thus, we seek a solution that allows customization in a systematic way. In this paper, we propose a metamodel for requirements models (called core metamodel) an...

Long-lived software systems often undergo evolution over an extended period. Evolution of these systems is inevitable as they need to continue to satisfy changing business needs, new regulations and standards, and introduction of novel technologies. Such evolution may involve changes that add, remove, or modify features; or that migrate the system from one operating platform to another. These c...

background: in process industries, production, storage, transportation, usage and disposal of chemicals are inherently dangerous and the risk of catastrophic accident occurrence is potentially high. to improve safety level in these industries, establishment of process safety management (psm) system is considered as the most effective measures. this study was conducted to determine the degree of...

nowadays, given different definitions and conceptions on development, territorial planning lends to for various economic, social and geographical aspects, however its defensive and security perspectives have been taken into account to less extent. the present research is aimed to specify passive defense legal requirements in territorial planning through outlining the most important rules on pas...

integrated rice-fish farming requires very little input and provides off season employment tofarm labors. it has been observed that combination of rice and fish farming is mutuallybeneficial. although, in implementation, it can be faced with several challenges and it demandssome requirements. so, this study was conducted to identify challenges and requirements ofintegrated rice-fish farming in ...

Systems requirements errors are numerous, persistent, and expensive. To detect such errors, and focus on critical ones during the development of a requirements document, we have defined Root Requirements Analysis. This simple technique is based on: generalizing requirements to form root requirements, exhaustively comparing the root requirements, and applying simple metrics to the resultant comp...
