This chapter explores using service-oriented computing to reengineer non-secure legacy software applications to create new secure target applications. Two objectives of this chapter are: (1) to analyze the architectural changes required in order to adopt new web technologies and cope with resultant vulnerabilities in source code; and (2) to measure the level of effort required to modernize software by adopting new web technologies and adding security countermeasures. To meet these objectives, a model-driven Scrum for Service-Oriented Software Reengineering (mScrum4SOSR) methodology was chosen and applied to a reengineering project. Scrum is employed to manage the reengineering project, as well as to measure implementation effort related to the modernization process. Further, a re-documentation technique called 5W1H Re-Doc is used to re-document the non-secure software application at a high level of abstraction in order to help project participants comprehend what is needed to identify candidate services for service-oriented reengineering. Case studies with and without security features are created for different types of applications - a desktop graphical user interface, a web application, a web services application, a restful web services application, and an enterprise service bus application.

AbstractNoSQL technologies have become a common component in many information systems and software applications. These technologies are focused on performance, enabling scalable processing of large volumes of structured and unstructured data. Unfortunately, most developments over NoSQL technologies consider security as an afterthought, putting at risk personal data of individuals and potentially causing severe economic loses as well as reputation crisis. In order to avoid these situations, companies require an approach that introduces security mechanisms into their systems without scrapping already in-place solutions to restart all over again the design process. Therefore, in this paper we propose the first modernization approach for introducing security in NoSQL databases, focusing on access control and thereby improving the security of their associated information systems and applications. Our approach analyzes the existing NoSQL solution of the organization, using a domain ontology to detect sensitive information and creating a conceptual model of the database. Together with this model, a series of security issues related to access control are listed, allowing database designers to identify the security mechanisms that must be incorporated into their existing solution. For each security issue, our approach automatically generates a proposed solution, consisting of a combination of privilege modifications, new roles and views to improve access control. In order to test our approach, we apply our process to a medical database implemented using the popular document-oriented NoSQL database, MongoDB. The great advantages of our approach are that: (1) it takes into account the context of the system thanks to the introduction of domain ontologies, (2) it helps to avoid missing critical access control issues since the analysis is performed automatically, (3) it reduces the effort and costs of the modernization process thanks to the automated steps in the process, (4) it can be used with different NoSQL document-based technologies in a successful way by adjusting the metamodel, and (5) it is lined up with known standards, hence allowing the application of guidelines and best practices.

Organizations are highly dependent on their software in carrying out their daily activities. Unfortunately, the repeated changes that are applied to these systems make their evolution difficult. This evolution may be necessary to maintain the software, replace or upgrade it. In the case of complex and poorly documented legacy systems, modernization is the only feasible solution to achieving the evolution goals. The OMG (Object Management Group) consortium created the Architecture-Driven Modernization (ADM) initiative to cope with the challenges of modernization. This initiative proposes, among other things, modernization through model-driven engineering (MDE). In this context, the modernization of a legacy system, not developed in an MDE environment, begins with its migration towards this type of environment. This migration raises the problem of finding the models necessary for the use of MDE representing this system.In this paper, we present a new bimodal approach to ADM modernization by enabling automatic and interactive modes to discover a view of the implementation platform of a legacy object-oriented system. Also, we present the key ideas of the algorithms behind this discovery process. Finally, we describe our prototype tool that implements our approach. This tool has been validated on several systems written in C# and Java languages.

А new approach to policy-making in the field of economic reforms in modernizing countries (on the sample of SME promotion) is the subject of this article. Based on summarizing the ten-year experience of de-bureaucratization policy implementation to reduce the administrative pressure on SME, the conclusion of its insufficient efficiency and sustainability is made. The alternative possibility is the positive reintegration approach, which provides multiparty policy-making process, special compensation mechanisms for the losing sides, monitoring and enforcement operations. In conclusion matching between positive reintegration principles and socio-cultural factors inherent in modernization process is provided.
