Based on the fact that many electronic devices are digitalized in our world in order to facilitate our lives, there is a large potential for development in the home. Smart Home solutions are giving us the opportunity to control and manage for example alarms, electricity and surveillance but the technology's rapid improvement paves the way for issues related to security. The objectives for this work will bring up common communication technologies, security and vulnerabilities in the context of a Smart Home and what could be done for future work.

This essay takes a look at Israel's security policy and the definition of threat as a major factor in building up the security policies. This essay brings up also the problems of having a realist way of acting towards a more constructivist problem, as it is in this case. To understand better the constructivist context an analysis of Israel's security policy and a research of its roots are made as well as how Palestine Liberation Organization (PLO), Hamas and Hezbollah are seen as threats to the Israeli state security. The aim is to look at the problem and at the basis of the foundation of both

Communication of confidential data over the internet is becoming more frequent every day. Individuals and organizations are sending their confidential data electronically. It is also common that hackers target these networks. In current times, protecting the data, software and hardware from viruses is, now more than ever, a need and not just a concern. What you need to know about networks these days? How security is implemented to ensure a network? How is security managed? In this paper we will try to address the above questions and give an idea of where we are now standing with the security o

The goal of the study is to create a laboratory infrastructure that allows instructors to quickly create virtualized environments for simulating various cyber threats. The testing environment for this demo consists of Windows 10, Ubuntu 16.4, Kali linux and OSSIM. Completed attacks together with potential moves are gathered and put into various attack tree diagrams for analysis so as to find out the most effective attacks against each host.

In today’s inter-connected world, threats from anywhere in the world can have serious global repercussions. In particular, two types of threats have a global impact: 1) cyber crime and 2) cyber and biological weapons. If a country’s environment is conducive to cyber criminal activities, cyber criminals will use that country as a basis to attack end-users around the world. Cyber weapons and biological weapons can now allow a small actor to inflict major damage on a major military power. If cyber and biological weapons are used in combination, the damage can be amplified significantly. Given tha

This thesis seeks to explain the discursive construction of national security threats facing the United States from 2001-2018. The driving argument is that the nation's perception of threats and conceptualization of itself are vulnerable to Presidential rhetoric. Presidents convey threats through rhetorical frameworks, a simplified means to present a manipulated perception of reality to a wider audience, which intentionally provoke reactions from the nation to garner consensus towards executive decision-making. Presidents apply frames from prior administrations as well as new frames to define

<p>The secessionist conflict in Transdniestrian region of the Republic of Moldova have led to more than a decade of political dialogueon finding a peaceful solution to conflict resolution, proving that the current format of negotiations is inefficient. The increased interest of the EU in the resolution of this conflict is caused by prospective inclusion of Romania in the EU, placing the Transdniestrian conflict at EU periphery, where confrontation is contrary to the all-European orientation at stability and integration. Presumably the involvement of the EU could lead to finding a political sol

Security Information and Event Management (SIEM) tools can be used to identify potential malicious insider activities.

A malicious actor often relies on security vulnerabilities of IT systems to launch a cyber attack. Most cloud services are supported by an orchestration of large and complex systems which are prone to vulnerabilities, making threat assessment very challenging. In this research, I developed formal and practical ontology-based techniques that enable automated evaluation of a cloud system's security threats. I use an architecture for threat assessment of cloud systems that leverages a dynamically generated ontology knowledge base. I created an ontology model and represented the components of a cl
