Abstract
Taxonomies are known to provide a systematic and theoretical classification of elements in a particular domain and could be efficiently used to express concepts in a structural manner. Unfortunately, security literature witnesses a few taxonomies having about 40 nodes on average in mostly a narrowed scope and maximum of 25 nodes on mobile scope only. This study surveyed security related taxonomies with quality criteria and proposes new comprehensive mobile security taxonomy and mobile malware analysis subtaxonomy from not only defensive but also offensive point of view. We have developed a levelling scheme and notation for security taxonomies in general and proposed a new definite method to build the taxonomies having over 1,300 nodes. We have also visualized our taxonomies for researchers, security professionals and even common end users to provide comprehensible, well structured, and handy maps. As security threats and vulnerabilities dynamically increase and diversify, these new taxonomies would help to see the entire perspective of mobile security without losing any details and present new perspective to bring mobile computing and cyber security disciplines closer.

Abstract
Application permissions at the core of Android security mechanism are the first leading transparent feature for users to assess any mobile application before download or installation and for experts to analyse any malware. Representing vast, dispersed permissions and achieving clarity is not a trivial matter. In this study, we first examined Android permissions, their groups and formal representations with the limitations. We also surveyed limited studies on clustering/visualization of permissions. We grouped 251 Android permissions into 12 clusters semantically and proposed a new visualization approach that looks more conventional to both end users and experts and helps comprehending permissions easily and quickly. We applied the proposed clustering and visualization on calculated discriminative malign permissions concept for malware analysis and demonstrated potential effectiveness of the approach. Our approach improves expressing and understanding of large number of mobile application permissions in a better context, provides more understanding and insight, and helps interpreting or inferring interesting patterns related to permissions for malware classification.

Abstract
This study presents the differences of two main focus points on cyber security: computer networks and software or application security. While the threats are heading towards the application layer, the defense seems to mainly concentrate on link, internet and transportation layers. This study addresses the imbalance that is confirmed with the latest statistics: latest cyber attacks having worldwide impact, and even in the topics covered in information and cyber security literature and conferences like the ones in Turkey lately.

Abstract
Keyloggers are powerful tools that can perform many task. Standard security measures for machine-to-machine interfaces do not protect computer systems from keylogger attacks. Human-to-machine interfaces must be considered to combat keylogger intrusions. The judicious use of keyloggers by employers and computer owners could, in some situations, improve security, privacy, and efficiency. But the possible positive effects must be balanced against the possible negative effects on employees, users, and children.

Abstract
In this study, spyware threatening information and computer security; cyber crime threatening privacy and personal security and current legal regulations in this scope preventing the threats in Turkey and in the world are reviewed. On one hand, the progress and enhancement in information technologies bring considerable benefits. While on the other hand, cyber crime against privacy and computer security increases significantly due to availability many spyware. Consequently, it is determined that since the e-structures in Turkey are not advanced, the interest in this matter and the legal regulations in this frame are limited and insufficient comparing to the countries having advanced e-structures. It is necessary to reconsider the subject by government, universities and NGOs in Turkey and prepare the dissuasive and comprehensive legal regulations that minimize the cyber crime and protect the privacy and computer security.

Abstract
This study introduces the threats encountered by children and teenagers using computer systems and Internet, revises what could be done to protect them, and presents some suggestions how the threats could be minimized. We can conclude that being aware of the usefulness of Internet facilities would not be enough to use Internet efficiently. Families and responsible state units should be focused on how to protect children, what sort of precautions are supposed to be done, how the experiences and knowledge could be improved and what sort of reactions to protect children and teenagers should be taken for further achievements.

Abstract
Although computer system security being upgraded day by day, the attacks against the systems have also increased. The attacks attempting to bypass the system increase in diversity and quantity. Monitoring and evaluating the attacks are essential requirements for building up a sufficient and efficient information and computer security system. In this study, we have reviewed the attacks conducted to computer system; evaluated attack-attacker relation; presented the common characteristics of attacks; inspected the tendency of the conducted attacks and fundamental attacks types. Consequently, the methods and methodology used in the attacks against computer systems must be studied. Targeted systems under attacks must be secured and upgraded. The characteristics of the attacks must be traced. The targeted vulnerabilities and weak points must be eliminated, and the attacker profile must be taken into account while determining the precautions. We can conclude that it is necessary to apply the security life cycle in securing the systems truly and efficiently to liminate the weaknesses and deficiencies faced in computer security systems to reduce the losses.

Abstract
Due to the rapid update of Internet newspapers or news sites, the page layout of Internet newspapers should be arranged so that the users can read easily and the page has minimum wasted space. Since the number of articles that users require and their contents are different it is hard to prepare an optimum page layout quickly. It is not possible to prepare these pages being updated frequently and used intensively by means of manual or classical methods in time. The appearance of this kind of pages should be well readable. Furthermore, the pages must be prepared depending on the settings of the user’s web browser. In this study, simulated annealing algorithm is used for the layout optimization of Internet newspapers. The articles that users inquire are placed on the page in the browser in users computers in an optimum layout. Making the page layout in real-time on the client-side as soon as all the articles are downloaded from the web server relieves the server load. The experimental results have showed that the implementation of simulated annealing algorithm is very effective and fast in real-time optimization of web page layout.

Abstract
Binary classification is one of the most frequent studies in applied machine learning problems in various domains, from medicine to biology to meteorology to malware analysis. Many researchers use some performance metrics in their classification studies to report their success. However, the
literature has shown a widespread confusion about the terminology and ignorance of the fundamental aspects behind metrics. This paper clarifies the confusing terminology, suggests formal rules to distinguish between measures and metrics for the first time, and proposes a new comprehensive visualized roadmap in a leveled structure for 22 measures and 22 metrics for exploring binary classification performance. Additionally, we introduced novel concepts such as canonical notation, duality, and complementation for measures/metrics, and suggested two new canonical base measures simplifying equations. It is expected that the study will guide other studies to have standardized approach to performance metrics for machine learning based solutions.

Abstract
Mobile devices as the most pervasive technology enablers also bring new security risks in cyberspace. However, related cyber security studies mainly focus on technologies and practices rather than fundamentals and root causes. These studies may also omit the current scientific knowledge gained on other relevant or irrelevant domains that may be adapted to cyber security and ignore human nature that is more important than technology and processes. This study surveys and associates all the analogical methods and proposes them to avoid such problems. Several examples on each analogical method are collectively provided to explore cyber/mobile security as a multidisciplinary complex domain and uncover some unknown facts or inconspicuous matters from other domains. As cyber attacks continue globally and effective cyber security could not be established, analogical methods will be method of choice. The study also extends the scientific inquiry with analogy and proposes a new comprehensive allegoric approach that is unprecedented in cyber security literature and questions mobile technologies and their security based on Plato’s infamous allegory of the cave.

Abstract
This Technical Report describes the requirement for a secure and automated information exchange between a NATO SECRET domain and lower level domains. The document presents some possible solutions to implement an Information Exchange Gateway (IEG) that support a secure and automated information exchange from a domain with classification up to SECRET to lower level domains (e.g. UNCLASSIFIED). The IEG Scenario D (IEG-D) is relevant for the interconnection of a NATO CIS with a NNEs CIS and specific use cases are introduced to describe the operational need of secure information sharing between NATO and other entities (such as International Organizations (IOs), Governmental Organization (GO), Non-Governmental Organization (NGOs)). The IEG-D is detailed in terms of system architecture and by proposing a specific possible implementation that can address the identified use cases.

Abstract
Conventional energy grids growing in time have become complex, inefficient and expensive to operate and use. They are critical because of providing the whole energy needs of the technologies required for our modern life but also cumbersome entities. "Smarting" the grids by automating, facilitating the troubleshooting and productivity analysis with the help of information technologies infrastructure, reinforcing the controls, charging the services in details makes it possible to administrate efficiently and provide high-level quality services. But, cyber threats have involved in as a game-changer. This paper summarizes the inevitable strategic cyber security approach to be demonstrated against cyber threats and attacks exploiting the vulnerabilities of the smart grids that are one of the cyber-physical systems in critical infrastructures of many national cyber security strategies.
