Pille Pullonen, Jake Tom, Raimundas Matulevičius, Aivo Toots

Software and Systems Modeling > 2019 > 18 > 6 > 3235-3264

Privacy-enhancing technologies play an important role in preventing the disclosure of private data as information is transmitted and processed. Although business process model and notation (BPMN) is well suited for expressing stakeholder collaboration and business processes support by technical solutions, little is done to depict and analyze the flow of private information and its technical safeguards...

An Approach to Capture Role-Based Access Control Models from Spring Web Applications

Andrey Sergeev, Raimundas Matulevicius

2017 IEEE 21st International Enterprise Distributed Object Computing Conference (EDOC) > 159 - 164

2017 IEEE 21st International Enterprise Distributed Object Computing Conference (EDOC)

To mitigate potential misinterpretation and security violations, software developers should use tools that reflect the state of web applications and visualise them as graphical models. Modelling helps to ensure that functionality and access control mechanisms are consistently interconnected. In this paper, we propose an approach to support Web application development using the Spring platform. Our...

A Systematic Approach to Define the Domain of Information System Security Risk Management

Éric Dubois, Patrick Heymans, Nicolas Mayer, Raimundas Matulevičius

Intentional Perspectives on Information Systems Engineering > 289-306

Today, security concerns are at the heart of information systems, both at technological and organizational levels. With over 200 practitioner-oriented risk management methods and several academic security modelling frameworks available, a major challenge is to select the most suitable approach. Choice is made even more difficult by the absence of a real understanding of the security risk management...

Validity of the Documentation Availability Model: Experimental Definition of Quality Interpretation

Raimundas Matulevičius, Naji Habra, Flora Kamseu

Lecture Notes in Computer Science > Advanced Information Systems Engineering > Session 6: Case Studies and Experiences > 236-250

System and software documentation is a necessity when making selection and acquisition decisions, when developing new and/or improving existing system and software functionality. A proper documentation becomes even more crucial for open source systems (OSS), where, typically, stakeholders from different communities are involved. However there exist only limited or no methodology to assess documentation...

Tool Support and Specification Quality: Experimental Validation of an RE-Tool Evaluation Framework

Raimundas Matulevičius, Guttorm Sindre

Lecture Notes in Computer Science > Perspectives in Conceptual Modeling > Quality Driven Processes > 433-443

Automated support for the requirements engineering (RE) process is a recognised research area. However, the practice still relies on office tools rather than RE-tools. Reasons include financial causes and difficulty to evaluate the available RE-tools. This work reports on an experiment trying to validate a previously proposed framework for evaluating RE-tools. The experiment participants used several...

Visually Effective Goal Models Using KAOS

Raimundas Matulevičius, Patrick Heymans

Lecture Notes in Computer Science > Advances in Conceptual Modeling – Foundations and Applications > Requirements and Goals – Methods > 265-275

Goal modelling languages are visual modelling languages. To communicate ideas effectively with a visual modelling language, one should follow some basic principles. One is modularity, i.e. organising diagrams in manageable modules to avoid confusing the reader with overly complex diagrams. Another is emphasis, i.e. visually drawing the attention to the most important pieces of information. In this...

A Large Scope Transformational Approach for Distributed Architecture Design

Fabian Gilson, Vincent Englebert, Raimundas Matulevičius

Lecture Notes in Computer Science > Software Architecture > Research Challenge Papers > 330-333

Many Architecture Description Languages (ADLs) appeared in order to model complex software solutions. Unfortunately, current modeling approaches do not take into account infrastructure related constraints and do not add non-functional requirements to architecture constructs. This paper describes a transformation-oriented method to design distributed software architectures. Our method is based on an...

Adapting Secure Tropos for Security Risk Management in the Early Phases of Information Systems Development

Raimundas Matulevičius, Nicolas Mayer, Haralambos Mouratidis, Eric Dubois, more

Lecture Notes in Computer Science > Advanced Information Systems Engineering > Information Systems Engineering > 541-555

Security is a major target for today’s information systems (IS) designers. Security modelling languages exist to reason on security in the early phases of IS development, when the most crucial design decisions are made. Reasoning on security involves analysing risk, and effectively communicating risk-related information. However, we think that current languages can be improved in this respect. In...

Comparing Goal Modelling Languages: An Experiment

Raimundas Matulevičius, Patrick Heymans

Lecture Notes in Computer Science > Requirements Engineering: Foundation for Software Quality > 18-32

Although goal modelling is a recognised research area, only few empirical studies are reported. In this work we present an experiment where the quality of two goal languages – i* and KAOS – is investigated by means of the semiotic quality framework. We believed that a high quality language would contribute to effective and efficient modelling, and result in high quality models. But the experiment...

How Requirements Specification Quality Depends on Tools: A Case Study

Raimundas Matulevičius

Lecture Notes in Computer Science > Advanced Information Systems Engineering > Requirements Engineering > 353-367

Requirements specification is a complex activity, where the automated support by the requirements engineering (RE) tools plays an important role. However, the surveys report that the mainstream practice relies on office and modelling tools rather than the targeted RE-tools. This work performs a case study, where two requirements specification processes are analyzed. In order to prepare a requirements...

Modelling families of business process variants: A decomposition driven method

Fredrik Milani, Marlon Dumas, Naved Ahmed, Raimundas Matulevičius

Information Systems > 2016 > 56 > C > 55-72

Business processes usually do not exist as singular entities that can be managed in isolation, but rather as families of business process variants. When modelling such families of variants, analysts are confronted with the choice between modelling each variant separately, or modelling multiple or all variants in a single model. Modelling each variant separately leads to a proliferation of models that...

Criteria and Heuristics for Business Process Model Decomposition

Fredrik Milani, Marlon Dumas, Raimundas Matulevičius, Naved Ahmed, more

Business & Information Systems Engineering > 2016 > 58 > 1 > 7-17

It is generally agreed that large process models should be decomposed into sub-processes in order to enhance understandability and maintainability. Accordingly, a number of process decomposition criteria and heuristics have been proposed in the literature. This paper presents a review of the field revealing distinct classes of criteria and heuristics. The study raises the question of how different...

Securing business processes using security risk-oriented patterns

Naved Ahmed, Raimundas Matulevičius, N. Ahmed, R. Matulevicius

Computer Standards & Interfaces > 2014 > 36 > 4 > 723-733

Business process modelling and security engineering are two important concerns when developing information system. However current practices report that security is addressed at the later development stages (i.e. design and implementation). This raises a question whether the business processes are performed securely. In this paper, we propose a method to introduce security requirements to the business...

A taxonomy for assessing security in business process modelling

Naved Ahmed, Raimundas Matulevicius

IEEE 7th International Conference on Research Challenges in Information Science (RCIS) > 1 - 10

2013 IEEE Seventh International Conference on Research Challenges in Information Science (RCIS)

The idea of business processes as a key concept to underpin organisational activities are increasingly recognised. Business processes must be able to accommodate security engineering from the early stages rather at the later stages of process development (i.e., design and implementation). This raises a question whether the business processes are performed securely. In this paper, we take a deeper...

The Unified Enterprise Modelling Language—Overview and further work

Victor Anaya, Giuseppe Berio, Mounira Harzallah, Patrick Heymans, more

Computers in Industry > 2010 > 61 > 2 > 99-111

The Unified Enterprise Modelling Language (UEML) aims at supporting integrated use of enterprise and IS models expressed using different languages. To achieve this aim, UEML offers a hub through which modelling languages can be connected, thereby paving the way for also connecting the models expressed in those languages. This paper motivates and presents the most central parts of the UEML approach:...

Visual syntax does matter: improving the cognitive effectiveness of the i* visual notation

Daniel L. Moody, Patrick Heymans, Raimundas Matulevičius

Requirements Engineering > 2010 > 15 > 2 > 141-175

Goal-oriented modelling is one of the most important research developments in the requirements engineering (RE) field. This paper conducts a systematic analysis of the visual syntax of i*, one of the leading goal-oriented languages. Like most RE notations, i* is highly visual. Yet surprisingly, there has been little debate about or modification to its graphical conventions since it was proposed more...
