Security Architecture for the TEAMDEC System
… presenting big challenges to network security. In general, the web was designed with little concern for security. Thus, the issue of security is important in the design of network-based applications. The software architecture proposed in this thesis allows for the secure and efficient …

A Defense-In-Depth Security Architecture for Software Defined Radio Systems
… a system. Previous research concerning wireless security mainly focuses on vulnerabilities within pro- tocols rather than in the radios themselves. This dissertation specifically addresses this new threat against software radios and introduces a new security model intended to mitigate this …

An Arctic Nuclear Weapons Free Zone – In Search of a Security Architecture for the Arctic
… (the inclusion of partial territory, negative security assurances, members of a collective security alliance joining a NWFZ, and the prohibition of the transit of nuclear weapons through the high seas of a NWFZ). The second contribution is the elaboration of a ‘menu’ of Arctic-specific CBMs and …

Security management for mobile ad hoc network of networks (MANoN
… MANoN makes such networks highly vulnerable to security attacks compared with wired networks or even normal mobile ad hoc networks. This thesis presents a novel security-management system based upon the Recommendation ITU-T M.3400, which is used to evaluate, report on the behaviour of our MANoN …

Understanding and Improving Security of the Android Operating System
<p>Successful realization of practical computer security improvements requires an understanding and insight into the system's security architecture, combined with a consideration of end-users' needs as well as the system's design tenets. In the case of Android, a system with an open, modular …

NATO and post-Cold War German-American relations (1990-1997
… integration, and a continued German-American security connection within the Atlantic Alliance are the defining elements. This thesis examines some of the implications of NATO's new cooperative relations with former adversaries in Central and Eastern Europe and of the construction process of …

Strengthening embedded system security with PUF enhanced cryptographic engines
Mobile security is a vast research world with an ever-changing landscape. Researchers develop security solution one day just to see them overcome a week later. Protocols and specifications are generated that attempt to create order out of the chaos and provide a clear roadmap to the future of …

Automated Defense Against Worm Propagation.
… destruction over the last few years. Network security elements such as firewalls, IDS, etc have been ineffective against worms. Some worms are so fast that a manual intervention is not possible. This brings in the need for a stronger security architecture which can automatically react to stop …

African Union Peacekeeping and Civilian Protection. An Evaluation of the EU Strategy for Africa and the G8/Africa Joint Plan.
… is in the process of developing its peace and security architecture. Over the past decade, the international community has been supporting African peacekeeping, both to build AU capacity and to provide direct operational support. In 2005 the international community agreed a collective …

Holistic Security Engineering for Software-Defined Vehicles
… from cyberattacks by designing and implementing security concepts in the main phases of a vehicle's lifecycle. We use SAE level 4 prototype vehicles to evaluate our proposed techniques. We start with a systematic security requirement analysis using the ISA-62443 standard series, demonstrating how …

Capability-based access control for cyber physical systems
… creating technical, usability, and economic security challenges beyond those of information systems. Their distributed and hierarchical nature, real-time and safety-critical requirements, and limited resources create new vulnerability classes and severely constrain the security solution …

CAESAR8: an agile enterprise architecture approach to managing information security risks in business change projects
Implementing an Enterprise Architecture (EA) should enable organizations to increase the accuracy of information security risk assessments. Studies show that EAs provide an holistic perspective that improves information security risk management (ISRM). However, many organizations have been unable …

Computer Virus Spread Containment Using Feedback Control.
In this research, a security architecture based on the feedback control theory has been proposed. The first loop has been designed, developed and tested. The architecture proposes a feedback model with many controllers located at different stages of network. The controller at each stage gives …

A virtual machine architecture for IT-security laboratories
This thesis discusses challenges in IT security education, points out a gap between e-learning and practical education, and presents a work to fill the gap. E-learning is a flexible and personalized alternative to traditional education. Nonetheless, existing e-learning systems for IT security …
