Zagrożenia bezpieczeństwa wewnętrznego Niemiec jako konsekwencja procesów imigracyjnych
2017
In the Federal Republic of Germany there is a visible growth of the importance of immigration policy, of the weight of the problem of integration/lack of integration of mi- grants with the German society is visible, and of the need for permanent monitoring of internal security threats and difficulties with their prevention and fighting them. Many researchers working on the internal security of Germany admit that the current threats are linked, by the majority of Germans, with the influx of immigrants to this country. The migrants are seen as a source of potential risks, dangers and internal conflicts. It might be argued that there is an undeniable correlation between migra tion and security…
Organisational GDPR Investments and Impacts
2023
The aim of this empirical multi-case study is to understand the GDPR investments and impacts of the organisations. Among these, the measuring experiences related to GDPR and information security (Isec), and the future expectations are examined. Several interesting findings were recognised, which also enabled further suggestions. First, an understanding of the organisations’ investments and their impact is built by gathering information about the actions that organisations made to fulfil the GDPR requirements. In the second phase, it is deemed necessary to examine how organisations experience the measures and evaluation of GDPR development and progress, in order to understand how respondents…
APT Cyber-attack Modelling: Building a General Model
2022
The global community continues to experience an increase in the scale, sophistication, and successful perpetration of cyber-attacks. As the quantity and value of electronic information have increased, so too have the efforts of criminals and other malicious actors who have embraced the Internet as a more anonymous, convenient, and profitable way of carrying out their activities. The systems are attacked more and more by single or multiple hacktivists, state sponsored hackers, cyber criminals, cyber terrorists, cyber spies, or cyber warfare warfighters. The cyber security approach requires a balance of cyber threat intelligence, real time cyber-attack detection and especially the cyber early…
Le renouvellement du contrôle juridictionnel de l’administration au moyen du recours pour excès de pouvoir
2017
The role of the administrative judge (the excess of power) has evolved due to the implementation of the various texts adopted recently as well as the developments in the case-law in recent years. In many areas, its role now goes beyond the mere confrontation of an administrative act with the rule of law. At the heart of the annulment decision is a statement and an assessment of the facts, apart from the interpretation of the law, which were usually separated by the principle of separation between the administration and its judge.Some jurisprudence which has become very classical, as well as others more recent, can be considered as characteristic manifestations of this new tendency of the ju…
Method and Practical Guidelines for Overcoming Enterprise Architecture Adoption Challenges
2017
During the last few years, interest towards Enterprise Architecture (EA) has increased, not least due to anticipated benefits resulting from adopting it. For instance, EA has been argued to provide cost reduction, technology standardisation, process improvement, and strategic differentiation. Despite these benefits, the EA adoption rate and maturity are still low. Consequently, EA benefits are not realised. A major reason hindering the adoption is that EA is not understood correctly. This paper aims for minimising the effect of the lack of understanding EA to adopting EA. Based on the research conducted in Finnish public sector, we propose an improved Enterprise Architecture Adoption Method…
The end of the Euro-Atlantic pluralistic security community? the new agenda of transatlantic security relations in the global political system
2009
The chapter analyses security relations between the US and the EU, as reflected in the new agenda of transatlantic security relations and in its outcomes. Differences in international actorness, in the strategic culture and in threat perception between the two international actors are analyzed. It is noted that, the emerging of security challenges not strictly of a military type, most often transnational in nature, creates an incentive for the two actors to cooperate. An empirical analysis of the answers given by the US-EU to international security crises in the period 1990-2000 is conducted to show that a US-EU cooperation nucleus, built on the long practice of the Atlantic cooperation, is…
Unsupervised network intrusion detection systems for zero-day fast-spreading network attacks and botnets
2015
Today, the occurrence of zero-day and complex attacks in high-speed networks is increasingly common due to the high number vulnerabilities in the cyber world. As a result, intrusions become more sophisticated and fast to detrimental the networks and hosts. Due to these reasons real-time monitoring, processing and intrusion detection are now among the key features of NIDS. Traditional types of intrusion detection systems such as signature base IDS are not able detect intrusions with new and complex strategies. Now days, automatic traffic analysis and anomaly intrusion detection became more efficient in field of network security however they suffer from high number of false alarms. Among all …
Safety Evaluation of Turbo-Roundabouts with and without Internal Traffic Separations Considering Autonomous Vehicles Operation
2021
The paper presents a microsimulation approach for assessing the safety performance of turbo-roundabouts where Cooperative Autonomous Vehicles “CAVs” have been introduced into the traffic mix alongside conventional vehicles “CVs”. Based on the analysis of vehicle trajectories from VISSIM and subsequent analysis of traffic conflicts through the Surrogate Safety Assessment Model (SSAM), the research aims to evaluate the safety benefits of turbo-roundabouts where the lanes are physically separated by raised curbs, compared to roundabouts without such curbs. The paper will then describe the methodological path followed to build VISSIM models of turbo-roundabouts with and without raised curbs in …
Masquerader detection in mobile context based on behaviour and environment monitoring
2007
Mobiilipäätelaitteiden, matkapuhelimien ja kämmentietokoneiden yleistymisen myötä riski näiden laitteiden väärinkäytölle on kasvanut. Matkapuhelimia ja kämmentietokoneita varastetaan ja hukataan koko ajan. Tällöin on mahdollista laitteen päätyminen henkilölle, joka voi käyttää laitetta luvattomasti. Luvattoman käytön estämiseksi on syntynyt tarve turvajärjestelmälle, jonka avulla voidaan varmistaa, että mobiilipäätelaitetta käyttävällä henkilöllä on oikeus laitteen käyttöön.Mazhelis kehitti väitöskirjassaan menetelmää, jonka avulla mobiilipäätelaitteen laillinen käyttäjä erotetaan muista henkilöistä. Tähän pyritään käytön aikaista toimintaa ja toimintaympäristön informaatiota analysoimalla.…
Intervention Effect Rates as a Path to Research Relevance : Information Systems Security Example
2018
In the current information systems security (ISS) research, new theory contributions are especially valued. This research typically reflects the following formula: Suggest a new theory (or set of constructs) of ISS and show that it is empirically supported, then suggest another new theory (or set of constructs with some linkages) and show that it is empirically supported, and so on. Despite the merits of this approach, it leaves out many important scientific aspects. For example, after more than 30 years of ISS research, (1) we know little about the conditions and situations to which new theories (or constructs) do not apply; (2) we do not know which new theories are more effective than oth…
