This thesis presents security issues and vulnerabilities in home and small office local area networks that can be used in cyber-attacks. There is previous research done on single vulnerabilities and attack vectors, but not many papers present full scale attack examples towards LAN. First this thesis categorizes different security threads and later in the paper methods to launch the attacks are shown by example. Offensive security and penetration testing is used as research methods in this thesis. As a result of this thesis an attack is conducted using vulnerabilities in WLAN, ARP protocol, browser as well as methods of social engineering. In the end reverse shell access is gained to the target machine. Ready-made tools are used in the attack and their inner workings are described. Prevention methods are presented towards the attacks in the end of the thesis.

Endogenous development is defined as development that values primarily locally available resources and the way people organized themselves for that purpose. It is a dynamic and evolving concept that also embraces innovations and complementation from other than endogenous sources of knowledge; however, only as far as they are based on mutual respect and the recognition of cultural and socioeconomic self-determination of each of the parties involved. Experiences that have been systematized in the context of the BioAndes Program are demonstrating that enhancing food security and food sovereignty on the basis of endogenous development can be best achieved by applying a ‘biocultural’ perspective: This means to promote and support actions that are simultaneously valuing biological (fauna, flora, soils, or agrobiodiversity) and sociocultural resources (forms of social organization, local knowledge and skills, norms, and the related worldviews). In Bolivia, that is one of the Latin-American countries with the highest levels of poverty (79% of the rural population) and undernourishment (22% of the total population), the Program BioAndes promotes food sovereignty and food security by revitalizing the knowledge of Andean indigenous people and strengthening their livelihood strategies. This starts by recognizing that Andean people have developed complex strategies to constantly adapt to highly diverse and changing socioenvironmental conditions. These strategies are characterized by organizing the communities, land use and livelihoods along a vertical gradient of the available eco-climatic zones; the resulting agricultural systems are evolving around the own sociocultural values of reciprocity and mutual cooperation, giving thus access to an extensive variety of food, fiber and energy sources. As the influences of markets, competition or individualization are increasingly affecting the life in the communities, people became aware of the need to find a new balance between endogenous and exogenous forms of knowledge. In this context, BioAndes starts by recognizing the wealth and potentials of local practices and aims to integrate its actions into the ongoing endogenous processes of innovation and adaptation. In order to avoid external impositions and biases, the program intervenes on the basis of a dialogue between exogenous, mainly scientific, and indigenous forms of knowledge. The paper presents an analysis of the strengths and weaknesses of enhancing endogenous development through a dialogue between scientific and indigenous knowledge by specifically focusing on its effects on food sovereignty and food security in three ‘biocultural’ rural areas of the Bolivian highlands. The paper shows how the dialogue between different forms of knowledge evolved alongside the following project activities: 1) recuperation and renovation of local seeds and crop varieties (potato – Solanum spp., quinoa – Chenopodium quinoa, cañahua – Chenopodium pallidicaule); 2) support for the elaboration of community-based norms and regulations for governing access and distribution of non-timber forest products, such as medicinal, fodder, and construction plants; 3) revitalization of ethnoveterinary knowledge for sheep and llama breeding; 4) improvement of local knowledge about the transformation of food products (sheep-cheese, lacayote – Cucurbita sp. - jam, dried llama meat, fours of cañahua and other Andean crops). The implementation of these activities fostered the community-based livelihoods of indigenous people by complementing them with carefully and jointly designed innovations based on internal and external sources of knowledge and resources. Through this process, the epistemological and ontological basis that underlies local practices was made visible. On this basis, local and external actors started to jointly define a renewed concept of food security and food sovereignty that, while oriented in the notions of well being according to a collectively re-crafted world view, was incorporating external contributions as well. Enabling and hindering factors, actors and conditions of these processes are discussed in the paper.

In the following pages, three well-known Latinoamericanists share their views on the current prospects for coups in Latin America. They are: Rut Diamint of the University Torcuatto de Tella in Buenos Aires, Argentina; Pablo Policzer of the University of Calgary in Canada; and Michael Shifter of the Inter-American Dialogue in Washington, DC. Each looks at the potential for coups from different perspectives but, all three come to similar conclusions. That is, that despite substantial gains in democracy, the threat of coups in Latin America remains latent. The authors agree that democracy is growing in the region. Opinion surveys such as the Americas Barometer consistently show that citizens in Latin America have gradually incorporated democracy as part of their core value system. Yet, the authors argue convincingly that Latin America faces new types of interruptions to its democratic process that should be considered coups, even if not following the traditional style of military coup that predominated in the past. Situations that have taken place in Peru, Ecuador, Nicaragua, Honduras and other countries serve to illustrate the new trends. More specifically, Professor Diamint argues that in Latin America a culture of intolerance, demonization of the opposition, and the utilization of any method to achieve power prevails. In a region with a very high threshold of violence, governments fail to set an example of establishing a culture of debate, consensus, and transparency. This culture is inclined to uncontrollable political expressions, preferring confrontational means to resolve conflict. Within this scenario, “messianic” solutions are promoted and coups cannot be discarded as an option that would never transpire. Professor Policzer looks more closely to the constitutional loopholes that allow for a transformation of limited into absolute power. He argues that coups can be constitutional or unconstitutional, and that a constitutional coup can occur when violations to democracy actually stem from the constitutions themselves. In Honduras, for example specific provisions in the Constitution itself created conditions for a constitutional crisis; similar provisions have also led to constitutional authoritarianism in Venezuela and other countries. Dr. Policzer stresses that when a head of state or the military take absolute power, even temporarily, based on provisions in their constitutions; they are in essence staging a constitutional coup. These blind spots in constitutions, he argues, may be more serious threat to democracy than that of traditional coups. Lastly, Dr. Shifter argues that some kind of coup should be expected in Latin America in coming years, not only because fundamental institutions remain weak in some countries, but because the regional political environment is less prepared to respond effectively to transgressions than it was a few years ago. The good news, however, is that only a handful of countries, show no interest in governing. The bad news is that in those few countries where situations are indeed shaky, they are also in some cases aggravated by rising food and fuel prices, and spreading criminality, which pose serious risks to the rule of law and democratic governance.

This paper identifies a number of critical infrastructure applications that are reliant on location services from cooperative location technologies such as GPS and GSM. We show that these location technologies can be represented in a general location model, such that the model components can be used for vulnerability analysis. We perform a vulnerability analysis on these components of GSM and GPS location systems as well as a number of augmentations to these systems.
