Effects of PSD2 on security architecture of mobile banking : a review of literature
2017
This thesis aims to find out the changes that the Payment Service Directive (PSD2) will bring to the security architecture of mobile banking. PSD2 will create a situation where security mechanisms are separated from the actual banking application. Payment service providers must provide their Application Programming Interface for third party developers to give them access to authentication of payment transactions. PSD2 requires payments service providers to offer strong customer authentication with separate authentication mechanism from the banking application. This thesis found that academic literature about the security architecture of mobile banking does not provide a model where a separa…
Tietoturvan toteutus SD-WAN -operaattoripalveluissa
2017
Tutkielmassa selvitettiin vaihtoehtoja, joiden avulla palomuuraukseen liittyvä tekninen tietoturva voidaan toteuttaa uusissa SD-WAN -pohjaisissa verkottamisratkaisuissa ja niihin liittyvissä hybridiverkoissa operaattorin näkökulmasta. Palomuuraukseen liittyvää ratkaisua tulisi voida hyödyntää operaattorin asiakasverkoissa ja sen tulee skaalautua asiakkaiden käyttämien palveluiden mukaisesti. Tutkielmassa analysoitiin, kuinka SDN- ja NFV-teknologioita voidaan hyödyntää palomuurauksen toteutuksessa ja kannattaako palomuuraus toteuttaa SDN-pohjaisessa verkossa keskitetysti vai hajautetusti. Lisäksi pohdittiin, kuinka verkon hallinta voidaan toteuttaa keskitetysti, jotta jokaista verkon laitett…
Hajautettujen keinotekoisten neuroverkkojen soveltaminen langattomien lähiverkkojen tunkeutumisen havaitsemisjärjestelmiin
2011
Langattomien lähiverkkojen yleistyminen tarjoaa mahdollisille tunkeutujille uusia reittejä tietojärjestelmiin. Samaan aikaan tietojärjestelmien merkitys ihmisten ja yhteiskunnan kannalta kasvaa koko ajan. Tietojärjestelmiä turvaamaan tarvitaan tunkeutumisyritykset havaitsevia järjestelmiä. Tietotekniikan arkipäiväistyessä tietojärjestelmien käyttö koskettaa yhä useampia ihmisiä, joten järjestelmien helppokäyttöisyys korostuu entisestään. Tutkimuksessa selvitettiin itseoppiviin hajautettuihin neuroverkkoihin perustuvan tunkeutumisen havaitsemisjärjestelmän toteutusmahdollisuuksia. Tutkimuksen tuloksena esitellään tällaisen järjestelmän arkkitehtuuri. Arkkitehtuurin perusteella toteutettiin e…
Systemic Management of Architectural Decisions in Enterprise Architecture Planning. Four Dimensions and Three Abstraction Levels
2006
This paper presents a process model for the management of architectural decisions in enterprise architecture planning. First, decisions are made at the enterprise level, with strategic business considerations on the enterprise information, systems and technology strategy and governance issues. The next step is to define the domains, to then go on with domain architecture decisions. At the systems level, the enterprise and domain architecture decisions are collected and converted into architecture descriptions accurate in precision, form and detail to be given as input to the information systems development process, following the architectural planning. The model is derived from previous wor…
Basic Elements of Cyber Security for a Smart Terminal Process
2023
Global maritime transportation and logistics systems are essential parts of critical infrastructures in every society, and a crucial part of maritime logistics processes are seaports. Digitalization helps improve the efficiency of terminal systems in the processes of these ports. In Finland this development is going on and it is called SMARTER research program. In the best cases, digitalization can also promote the reduction of emissions by optimizing port operations and enhancing cargo and people flows while improving the experience for all stakeholders. The improvement of port processes relies on the development of Information and Communication Technology (ICT) and as well as on Industria…
Defining Complexity Factors for Architecture Evaluation Framework
2006
The design and implementation of telecommunication systems is an incremental and iterative process, and system architectures may need to be revised and refined several times during their lifetime. Formal evaluation facilitates the identification of the weak points, where improvements are due in these architectures. In the domain of telecommunications, such evaluation can be based on the Architecture Evaluation Framework (AEF). During the evaluation, a deep understanding of the processes within a system is needed. Meanwhile, the systems being designed are usually complex systems encompassing a large number of components with an intricate pattern of interaction between them. As a result, it i…
Elements of Sustainability for Public Sector Software : Mosaic Enterprise Architecture, Macroservices, and Low-Code
2021
Public sector is a large consumer for software. In countries such as Finland, many of the systems are made to order by consultancy companies that participate in public tenders. These tenders initiated by the state, cities, and other public sector organizations. Furthermore, as public sector tasks are often decomposed to various actors, each and every one of them makes their purchase based on their own needs. In this paper, we argue that to maintain software sustainability in this context, there is a need for three key elements. Firstly, there is a need for an enterprise architecture where independent services from various vendors are can be easily deployed and integrated. Secondly, these se…
Introduction to software product lines : Engineering, service, and management minitrack
2013
Software has become the key asset for competitive products and services in all industries. Thus, competitiveness in software development, maintenance, and related services has become a concern for organizations. Competitiveness can be increased through (1) internal strategies such as the strategic creation and reuse of software assets and (2) external strategies such as outsourcing software development, maintenance, and/or services from third party service providers and acquiring off-the-shelf components from providers and open source communities. A viable third strategy is to enact both strategies in parallel. This minitrack focuses on the first and third strategy. The minitrack accepted f…
Development of Network Security Education
2021
Distance education has grown tremendously over the last decade. Internet technologies have enabled a large-scale dispensation of lectures, exercises, and training. Virtual Learning Management Systems (LMSs) offer a number of tools to realize distance education and distance learning. In this work, we present a virtual system architecture for training cyber security professionals with hands-on skills. The architecture is based on a VirtualBox virtualization environment. Guest machines are installed on an instance of VirtualBox. The installed environment offers a safe and isolated workbench for experiments. After installation and configuration of the environment, students perform a number of i…
Genre and ontology based business information architecture framework (GOBIAF)
2007
Tiedon määrän kasvu on johtanut organisaatioiden tehokkuuteen kielteisesti vaikuttavaan tietotulvaan. Liiketoiminnan kannalta kriittisen tiedon asianmukainen hallinta on keskeistä organisaatioiden päätöksenteossa. Turo Kilpeläinen tarkastelee väitöstutkimuksessaan organisaatioiden strategisen päätöksenteon tukena käytetyn kokonaisarkkitehtuurin kehitystä liiketoimintaprosesseissa välittyvän kriittisen tiedon näkökulmasta.- Liiketoimintaprosesseissa käytettävä ja välittyvä tieto on yksi organisaatioiden pysyvä ja keskeinen hallittava kokonaisuus. Tiedon saatavuus halutaan varmistaa koko organisaatiossa. Esimerkiksi tuotantoprosessien aikana tiedon, tai sen puutteen merkitys konkretisoituu on…
