Data Mining Approach for Detection of DDoS Attacks Utilizing SSL/TLS Protocol

2015

Denial of Service attacks remain one of the most serious threats to the Internet nowadays. In this study, we propose an algorithm for detection of Denial of Service attacks that utilize SSL/TLS protocol. These protocols encrypt the data of network connections on the application layer which makes it impossible to detect attackers activity based on the analysis of packet payload. For this reason, we concentrate on statistics that can be extracted from packet headers. Based on these statistics, we build a model of normal user behavior by using several data mining algorithms. Once the model has been built, it is used to detect DoS attacks. The proposed framework is tested on the data obtained w…

A Battery-free Asset Monitoring System based on RF Wireless Power Transfer

2020

In the Internet of Things (IoT) era, asset monitoring represents an appealing implementation of Wireless Sensor Networks due to the enormous benefits associated with being able to monitor and record the exact position and transportation conditions of assets, personal objects, and the like. This kind of infrastructure enables the provision of increasingly advanced services, including the ability to measure the movement speed of a monitored asset using relatively inexpensive nodes with sensing capabilities and wireless transmission and reception. These nodes would ideally employ battery-free sensors that do not require any maintenance, but conventional power supply management systems cannot s…

Trust-enhanced data integrity model

2012

In this paper we propose an enhancement of data integrity model. The proposed model is based on the idea of Biba integrity model but uses more elaborated integrity measurements. Since integrity can be seen as “trustworthiness of data and resources”, we propose to utilize trustworthiness opinions from subjective logic and express levels of integrity as levels of trustworthiness.

A method to optimize a typology-based classification system

2014

This study sought to provide guidelines for implementing typology-based qualitative analysis of human movement patterns.Fifteen participant-analysts were instructed how to classify treading water behaviours into eight different categories using a training set of videos. They were later provided with two additional sets of videos called validation, and test sets. Results first identified reliable (n=9), and not reliable (n=6) analysts. A decision study outlined that one analyst was sufficient to reliably categorize the behaviours in the ‘reliable’ analyst group, whereas up to four were necessary in the ‘unreliable’ group. These data provided new insights into more objective qualitative analy…

Seismic Behavior of Lisbon Mixed Masonry-RC Buildings With Historical Value: A Contribution for the Practical Assessment

2018

The fact that linear analysis is still the most used procedure in the design engineering offices, studies which addresses issues associated to the estimation of the structural behavior factor values are relevant. In this study, the behavior factor of a particular type of mixed masonry-reinforced concrete buildings in Lisbon is estimated. The typology chosen in this study represents 30% of building stock in Lisbon; these buildings were built between 1930 and 1960 and thus were designed without considering the seismic-design requirements proposed in current codes. The evaluation of the behavior factors was based on the use of nonlinear static analyses, performed in the form of the sensitivity…

Determination of priority groups of indicators for threats identification to the financial security of insurance market

2017

The object of research is economic processes in insurance market of Ukraine. Generally there is no methodology for financial security assessment of the individual insurer and the insurance market in Ukraine, approved within the regulatory impact and determining financial security is not considered that hinders the practice of providing threats identification. To achieve the objectives author used the following methods: analysis and synthesis, logic synthesis, hierarchy analysis method. Methodological basis of the study is insurance theory and insurance concepts.As a result the aim of research was achieved, namely the priority groups of indicators for threats identification to the financial …

A Security Framework for Smart Ubiquitous Industrial Resources

2007

Conventional approaches to manage and control security seem to have reached their limits in new complex environments. These environments are open, dynamic, heterogeneous, distributed, self-managing, collaborative, international, nomadic, and ubiquitous. We are currently working on a middleware platform focused on the industrial needs, UBIWARE. UBIWARE integrates Ubiquitous Computing with Semantic Web, Distributed AI, Security and Privacy, and Enterprise Application Integration. In this paper, we describe our long-term vision for the security and privacy management in complex multi-agent systems like UBIWARE, SURPAS. The security infrastructure has to become pervasive, interoperable and inte…

Transformation of the European security system in the context of current geopolitical challenges

2017

W artykule rozważa się problem modernizacji europejskiego systemu bezpieczeństwa w kontekście współczesnych wyzwań geopolitycznych, zwłaszcza agresywnej polityki Federacji Rosyjskiej. Przeprowadzono analizę kształtowania systemu europejskiego bezpieczeństwa, biorąc pod uwagę wielowymiarowość i zdolność systemu, wyznaczono czynniki zagrożenia i wyzwania, które decydują obecnie o jego funkcjonowaniu. Autorzy zwracają uwagę na nieefektywność europejskiego systemu bezpieczeństwa, jego problemy i możliwe sposoby jego reformowania. Przeanalizowane główne instytucje europejskiego systemu bezpieczeństwa: NATO (szczególny wkład tej struktury w gwarantowanie pokoju i bezpieczeństwa na kontynencie eur…

L’occupation de l’Iraq. Le Conseil de sécurité, le droit de la guerre et le droit des peuples à disposer d’eux-mêmes

2004

By Resolutions No. 1483 and 1511 (2003), the Security Council authorized the occupying powers in Iraq to intervene in the political and economic affairs of the occupied territory beyond the limits provided for by international law of war. At the same time, this authorization restricts the right of the Iraqui peole to self- determination, considered in its external aspect. Thus, the problem arises whether it is within the Security Council's powers to adopt resolutions which restrict the enjoyment of rights protected by rules of jus cogens. Furthermore, because the occupying government interpreted these resolutions broadly, it may be asked whether this interpretation is lawful. From a close e…
