A method for security breach detection through file access monitoring and pattern recognition

In the enterprise context a common requirement is to protect confidential information, such as sensitive customer data, internal corporate data, or research findings, not only against external, but also internal unauthorized access. The rapidly changing technology environment has seriously affected the computer security of organizations and governments around the world. According to the 2013 Data Breach Investigations Report from Verizon, more than 47,000 reported security incidents, 621 confirmed data breaches, and 44 million compromised records have been analyzed in 2012. Security breaches cause enormous damage and cost organizations billions of dollars annually. Intrusion Detection Systems (IDS) or Intrusion Prevention Systems (IPS) are typical protection mechanisms that monitor security breaches. Nevertheless, these systems suffer from several major drawbacks, such as increased configuration complexity, high cost, high maintenance, high number of false alarms, and requiring a security administrator that can react with countermeasures to a security breach. In this context, the goal of this thesis is to develop a novel Breach Detection System (BDS) able to overcome the disadvantages of current IDSs or IPSs. In order to detect and analyze security breaches at the operating system level, with a special focus on file operations, a BDS will be conceptualized and implemented. The aim of this BDS is to enable Security Breach Detection through File Access Monitoring and Pattern Recognition. For this purpose, a sensor is used to gather information about the system behavior while the system is running in a controlled state. Additional, a pattern recognition engine derives patterns from file access events. These patterns are used to monitor a process that accesses a certain file, and to determine the legitimacy of the file operations. It can also be used to suggest a possible access permission to an administrator

Devaluation as a balance of payments corrective measure in Turkey

Ankara : The Department of Management and Graduate School of Business Administration of Bilkent Univ. , 1990.Thesis (Master's) -- Bilkent University, 1990.Includes bibliographical references leaves 44-45.The main purpose of this study is to examine emiprically whether or not devaluation could be relied upon as a means fo r correcting the balance of payments deficits in Turkey. The time period is the years between 1968-1984. In this study, an international trade model for Turkey is established to find out price and income elasticities of import and export demands. Restricted form of Marshal 1-Lerner condition (Harberger condition) is applied to see the effectiveness of devaluation. Import and export demands functions are estimated by both Ordinary Least Square and Two Stage Least Square methods to see how Turkey's case fits into the methodological controversy. Another issue considered is the choice between static and dynamic formulations of the export and import functions. It is found that import demand of Turkey is income elastic but price inelastic, whereas export demand for Turkey is elastic both w ith respect to the relative prices and income. Devaluation con be used as an effective tool in correcting the balance of payments in Turkey according to the study’s findings.Öztürk, ZeynepM.S

The usability of voluntary carbon markets as a financial instrument in Turkish forestry sector

There have been many international studies and cooperations to avoid global warming and climate change as being global disasters. As a result of these studies, to avoid these problems, bilateral, regional and multilateral cooperations, legal instruments, incentive mechanisms and international funds are developed. One of these instruments is global carbon market as a cost-effective method to combat climate change. Thanks to carbon markets, projects in renewable energy, energy efficiency, waste management and forestry sectors aiming to reduce greenhouse gas emissions can be developed at. As forests are the most important terrestrial carbon sinks and deforestation and forest degradation are the third-largest source of carbon emissions, forestry sector is one of the crucial sectors in this process. In this context, Turkish forestry sector should benefit from international markets for protection, improvement and sustainable management of forest resources. Currently, Turkish forestry sector has not taken any financial support from these markets. In this study, it is aimed to determine and evaluate opportunities provided by voluntary carbon markets for Turkish forestry sector financing

Sustainable ecotourism management in protected areas

In recent years, there is an increase in social and environmental awareness. As a result of this, tourists prefer tourism types which do not affect cultural and natural resources negatively. Thus, sustainable tourism and ecotourism activities in protected areas such as National Park and Natural Park have gained importance. Within this period, tourists and local community in these areas are most important stakeholders. There is no consensus about evaluation of sustainability, but overall approach is that sustainability can be defined with criteria ad indicators. In this study it is aimed to evaluate possible criteria and indicators for sustainable ecotourism in protected areas within the context of Turkish forestry

Tobin Tax - reducing the negative effects of capital controls and short-term capital movements

The phenomenon liberalization, with the influence of the Bretton Woods system that collapsed subsequent to the Oil Shock in 1970, first began with the efforts to discover markets to value the investments of these countries in the developed countries. In order to provide the desired capital figures, in the 1980s the developed countries, squeezed under the debt load together with insufficient capital accumulation and low saving rates, needed the foreign resources and, at this point, the liberalization process of capital gained importance. Realizing the growth and developmental targets of countries’ economies, their integration in the liberalization gained great importance. The developing countries’ integration in the system without the necessary arrangement in their financial structures had an effect in terms of disturbing the stability of the economies, particularly in short-term capital inflows. As much as the problem created by the speculative capital inflow, the immediate outflow of this capital, disturbing the balance of economies, also caused crisis. To minimize the negative influence of short-term capital, capital controls are emphasized. Just as these controls can have various application ways, the most emphasized and discussed application was Tobin tax. Even though there are various disagreements in terms of whether or not Tobin tax affected the capital inflows, the examples of Malaysia and Chile represent successful results. In the first section of this study, the development of the liberalization process will be examined. In the second section, the effects created by the capital movements, and particularly short-term capital movements, on the countries’ economies will be emphasized. In the third section, the capital controls and Tobin tax, suggested for reducing the negative effects of the short-term capital movements will be considered and the applicability and limitations of Tobin tax will be examined

Kliniksel Denetim Modelinin Mesleki ve Teknik Anadolu Lisesinde Uygulanabilirliği İle İlgili Yönetici ve Öğretmen Görüşleri

Klasik denetim yaklaşımları ve oluşturdukları imaj, denetime karşı olumsuz bir bakış açısı geliştirmiş olmakla beraber, denetim, yalnızca olanı ortaya koymaya çalışmaktan öteye geçememiştir. Günümüzde artık yeni denetim yaklaşımlarına ihtiyaç duyulduğu açıktır. Bu yaklaşımlar öğretmenin denetime olan bakış açısını değiştiren, kendisini mesleki anlamda geliştiren, öğretmen-denetmen işbirliğini doğuran etkili uygulamalar olmalıdır. Bu araştırmada, Çağdaş Denetim Yaklaşımlarından biri olan Kliniksel Denetimin, Mesleki ve Teknik Anadolu Lisesi’nde uygulanabilirliği ve öğretmenlerin bu yaklaşımın aşamaları ve alt boyutlarına bakış açıları, bir nitel araştırma türü olan durum çalışması ile ortaya konulmaya çalışılmıştır. Bu kapsamda 8 öğretmen ile görüşülmüş ve Kliniksel Denetim Yaklaşımının alt temalarını yansıtan sorular yöneltilmiştir. Verilen cevaplar doğrultusunda katılımcıların yalnızca 4’ünün Kliniksel Denetim’in bütün aşamalarına olumlu baktığı, diğer 4 öğretmenin ise kısmen olumlu bulduğu görülmüştür. Sonuç olarak bu yöntemin kullanılmasının olumlu sonuç vermeyeceği kanısına varılmıştır. Ayrıca öğretmenlerin bu denetim yaklaşımlarıyla ilgili eğitim almalarının, bakış açılarını değiştireceği düşünülmektedir

An Integrative Perspective on Understanding Human Functioning: Positive Clinical Psychology

The number of studies conducted with a holistic perspective as an alternative to the traditional clinical psychology approach has increased. It is noteworthy that studies examine the effects of positive concepts on human health in addition to discomfort. In this study, it was aimed to examine four concepts that are frequently researched in positive psychology, namely well-being, psychological resilience, hope and coping in an integrative context. Also, it was aimed to give information about the positive clinical psychology approach and the studies which investigate these four positive concepts. Studies were searched through PsycARTICLE, EBSCO and Pubmed electronic databases. Totally 208 studies were reached and 26 articles were included in this review article. As a result, the effective results in treatment of psychological disorders and increase of well-being of an individual with positive psychology interventions suggest that it is important to expand the positive perspective in clinical psychology. It is thought that it may be clinically important that the presence/increase of positive concepts as well as the absence/decrease of psychopathologies should be one of the treatment targets of mental health specialists. It is hoped that adopting an integrative perspective in future studies will enrich empirical research in the field of psychotherapy

Axonal Endoplasmic Reticulum Dynamics and Its Roles in Neurodegeneration.

The physical continuity of axons over long cellular distances poses challenges for their maintenance. One organelle that faces this challenge is endoplasmic reticulum (ER); unlike other intracellular organelles, this forms a physically continuous network throughout the cell, with a single membrane and a single lumen. In axons, ER is mainly smooth, forming a tubular network with occasional sheets or cisternae and low amounts of rough ER. It has many potential roles: lipid biosynthesis, glucose homeostasis, a Ca2+ store, protein export, and contacting and regulating other organelles. This tubular network structure is determined by ER-shaping proteins, mutations in some of which are causative for neurodegenerative disorders such as hereditary spastic paraplegia (HSP). While axonal ER shares many features with the tubular ER network in other contexts, these features must be adapted to the long and narrow dimensions of axons. ER appears to be physically continuous throughout axons, over distances that are enormous on a subcellular scale. It is therefore a potential channel for long-distance or regional communication within neurons, independent of action potentials or physical transport of cargos, but involving its physiological roles such as Ca2+ or organelle homeostasis. Despite its apparent stability, axonal ER is highly dynamic, showing features like anterograde and retrograde transport, potentially reflecting continuous fusion and breakage of the network. Here we discuss the transport processes that must contribute to this dynamic behavior of ER. We also discuss the model that these processes underpin a homeostatic process that ensures both enough ER to maintain continuity of the network and repair breaks in it, but not too much ER that might disrupt local cellular physiology. Finally, we discuss how failure of ER organization in axons could lead to axon degenerative diseases, and how a requirement for ER continuity could make distal axons most susceptible to degeneration in conditions that disrupt ER continuity
