Opis:
A key role in the development of smart Internet of Things (IoT) solutions is played by wireless communication technologies, especially LPWAN (Low-Power Wide-Area Network), which are becoming increasingly popular due to their advantages: long range, low power consumption and the ability to connect multiple edge devices. However, in addition to the advantages of communication and low power consumption, the security of transmitted data is also important. End devices very often have a small amount of memory, which makes it impossible to implement advanced cryptographic algorithms on them. The article analyzes the advantages and disadvantages of solutions based on LPWAN communication and reviews platforms for IoT device communication in the LoRaWAN (LoRa Wide Area Network) standard in terms of configuration complexity. It describes how to configure an experimental LPWAN system being built at the Department of Computer Science and Telecommunications at Poznan University of Technology for research related to smart buildings.

Opis:
Exploitation characteristics behaves as a decreasing valors factor (DVF) which can be connected with degradation processes. It is a structure that consists of independent attributes which represent situations generally connected with a given exploitation factor. The multi-attribute structure contains attributes directly and indirectly referring to the main factor. Attribute states, by definition, can only maintain or decrease their values. Such situations are met in security, reliability, exploitation, fatigues and many complex one-directed or irreversible processes. The main goal refers to protocol security analysis during the realization of the communication run that specifies the assessment of the level of current and oncoming threats connected with cryptography authentication. In the communication run, the operations of different protocols mutually interleave. Our concept is based on the algorithm of attributes correction during exploitation process realization (Blanchet et al., 2008). The monitoring and correcting procedures make it possible to provide forecast information about possible threats on the basis of the structure of the current attribute values.

Opis:
The goal of this exploratory case study is to identify different facets of news reporting on surveillance, privacy and data security, and more specifically, how risks in this context are portrayed. The theoretical foundation consists of two elements: 1) the concept of mediatized risk culture, and 2) the discursive arena model of risk communication, which provides the normative background for assessing news reporting. A text-mining approach (topic modeling) is applied to analyze relevant coverage of the German quality newspaper Süddeutsche Zeitung. The study yields a total of seven topics which belong to three categories: violation of privacy norms, power and law enforcement, and datafication. The results show that despite the de-mystification of digital technology after the Snowden leaks, coverage has recently become more affirmative and less focused on risk. We conclude that this may indicate a normalization of mass surveillance and data harvesting even in Germany, a society which traditionally values privacy. In order to add more context to our findings, however, further qualitative analyses were needed. The paper serves as a starting point for further research on media reporting of surveillance, privacy and data security.

Opis:
The penetration of media and information technologies into the absolute majority of citizens' lives requires that, in defending and pursuing its intentions in the subject-matter area, the State should view it in the most erudite manner and should be capable of responding to it professionally. This fact is even more crucial in the post-socialist countries, where, in light of their totalitarian past, state bodies are often perceived through the lens of stereotypes as being deformed in the sense that the State performs more repressive than protective roles; that it is a bad owner in general terms; or even that it mismanages the tax payers’ money. The situation in the field of security is of special seriousness, where the State, being its principal guarantor, must seek to attain the highest possible level of credibility. However, one of the phenomena that may damage or weaken this credibility is a leak of State-classified information, as a result of which the credibility of an institution responsible for administering the security of classified information could be damaged significantly.
Obecność mediów i technologii informacyjnych w życiu dużej większości obywateli wymaga aby państwo w sposób profesjonalny reagowało na to zjawisko. Jest to szczególne ważne w byłych krajach socjalistycznych gdzie, w świetle ich totalitarnej przeszłości, rola państwa jest często rozpatrywana w kontekście władzy represyjnej a nie protekcyjnej. Jest to więc władza definiowana jako zły gospodarz, które źle zarządza publicznymi pieniędzmi. Szczególnie ważna jest kwestia bezpieczeństwa, której głównym gwarantem jest państwo osiągające wysoki poziom wiarygodności. Jednak jednym ze zjawisk, które mogą zniszczyć lub osłabić tę wiarygodność jest przeciek tajnych infor-macji. W skutek takiego przecieku, autorytet instytucji państwowych odpowie-dzialnych za utrzymanie bezpieczeństwa tajnych informacji, może zostać bardzo poważnie podważony.

Opis:
The subject of the work is the issue of analysis and interpretation of non-verbal behavior referenced to the security context and its threats. The fundamental thesis of the work is to prove the crucial role of knowledge and practical skills in the recognition and presentation of nonverbal behavior in crisis situations and emergencies. The author also points out the possibility of preparing and carrying out training in dealing with non-verbal messages for members of dispositional groups. In the analysis, the issue of the difference between the non-verbal and verbal behavior is discussed. Then the environmental issues of communication are analyzed in the form of importance of factors such as perception of situation, perception of time, presence of other people and architectural elements. In the same area dimensions of relations, knowledge on environment and people are located. The scope of non-verbal communication also includes close surroundings of a person and things possessed by him/her. Other important elements of the communication environment analysis are territory and personal space. Distinction is made between types of territory. In connection with the issue of space the author also introduced categorization of distance to the partner. In conclusion the need and usefulness of communication behavior model constructing, and conducting empirical research in this area are pointed out.

Opis:
Defending against DoS (denial of service) attacks has become a great challenge, especially for institutions that provide access to their services in the public network. State-of-the-art identity concealing tools and vast number of computers connected to the network require ensuring appropriate means for entities at risk to enable defence from the particular type of threats. This article presents a concept of user authentication in IP communication. The concept consists in providing the receiver with the possibility to determine sender՚s identity at the Internet layer level. This provides both the capability of defence against DoS attacks and possibility of utilizing the presented model over existing Internet network, which is directly responsible for transmission. The authors hope that the concept is a significant step in the perception of public network data transmission.

Opis:
Visible Light Communication (VLC) is a technique for high-speed, low-cost wireless data transmission based on LED luminaries. Wireless LAN environments are a major application of VLC. In these environments, VLC is used in place of traditional systems such as Wi-Fi. Because of the physical characteristics of visible light, VLC is considered to be superior to traditional radio-based communication in terms of security. However, as in all wireless systems, the security of VLC with respect to eavesdropping, signal jamming and modification must be analyzed. This paper focuses on the aspect of jamming in VLC networks. In environments where multiple VLC transmitters are used, there is the possibility that one or more transmitters will be hostile (or "rogue"). This leads to communication disruption, and in some cases, the hijacking of the legitimate data stream. In this paper we present the theoretical system model that is used in simulations to evaluate various rogue transmission scenarios in a typical indoor enviro.The typical approach used so far in jamming analysis assumes that all disruptive transmissions may be modeled as Gaussian noise, but this assumption may be too simplistic. We analyze and compare two models of VLC jamming: the simplified Gaussian and the exact model, where the full characteristics of the interfering signal are taken into account. Our aim is to determine which methodology is adequate for studying signal jamming in VLC systems.

Opis:
Contemporary time, interpreted by the prism of security, is no longer dominated by easy to describe inter-state conflicts or regional threats. Experts every now and then define new types of threats such as cybercrime, cyberterrorism or cyberwar. The intense and multi-level uncertainty affects the understanding of the present and the predicted future, and thus the search for security by all of us. The answer depends in part on whether we are able to understand contemporary security environment. These issues are, to my mind, independent of the place in which we are. Using tools for diagnosing and monitoring security remains an open question. At the moment we are searching for a solution to this problem by means of modern technologies. The paper stresses the importance and application of e.g. Internet technology and global telecommunication. Interpersonal relations are being replaced with technological solutions. Nowadays, a phone or a computer connected to the web is sufficient to make contact with another person or check what information official sources are bringing us today. Actions for security as a result of incorrect reception of a message may be associated with erroneous perception of the content and propaganda. As a result, the recipient is consciously manipulated. New technologies take the form of nonconventional, organized activities for security. Any number of people can cooperate through the web for security management without actual superior authority. Members of such groups, established ad hoc, may use their knowledge to express objections or dissatisfaction. The paper also presents another aspect of using technology. According to the author, there are situations in which technologies acting for reinforcing security often cause objection, motivated by restricting civil freedoms and by the threat of an attack on a free and open society.

Subject and purpose of work: The main goal is to offer more productive approach to security culture: viewing culture as a logical system which can be understood using theories and principles developed. Materials and methods: Cultural security issue collaborative research and discovery of literature to fully exploit social networks and open source material. Results: Cultural security issue analyzes the hard and soft power of antiquities, artworks, religious monuments, and historic structures as indicators of the political economy of cultural property. Conclusions. Analyses of the political significance of historic structures and religious monuments and the licit and illicit global market for antiquities and artworks provide insights into the strategic role of cultural property in diplomacy and international security. Integrating operational cultural principles into the specific conditions is the future and will bring depth to touchstones such as “no better friend, no worse enemy,” and “first, do no harm”.
Subject and purpose of work: Głównym celem pracy jest zaproponowanie bardziej efektywnego podejścia do kultury bezpieczeństwa: postrzegania kultury jako logicznego systemu, który można zrozumieć za pomocą opracowanych teorii i zasad. Materiały i metody: Badania nad bezpieczeństwem kulturowym realizowane w ramach współpracy oraz przegląd literatury, aby w pełni wykorzystać sieci społecznościowe i publiczne materiały źródłowe. Wyniki: Bezpieczeństwo kulturowe analizuje twardą i miękką siłę antyków, dzieł sztuki, zabytków sakralnych i budowli historycznych jako wskaźników ekonomii politycznej dóbr kultury. Wnioski: Analizy politycznego znaczenia budowli historycznych i zabytków religijnych oraz legalnego i nielegalnego globalnego rynku antyków i dzieł sztuki umożliwiają wgląd w strategiczną rolę dóbr kultury w dyplomacji i bezpieczeństwie międzynarodowym. Włączenie operacyjnych zasad kulturowych w określone warunki to kwestia przyszłości, która nada również głębszy wyraz takim fundamentalnym zasadom, jak „nie ma lepszego przyjaciela, ani gorszego wroga” oraz „po pierwsze, nie szkodzić”.
