Service Oriented Architecture (SOA) Security Models
… efficiency, and interoperability.</p> <p>Many security technologies, models and systems have been developed for SOA, covering one or a combination of security aspects such as authentication, authorization, encryption, trust, confidentiality or access control. Even though many security areas …

Security models in rewriting logic for cryptographic protocols and browsers
… tackles crucial issues of web browser security. Web browsers are now a central part of the trusted code base of any end-user computer system, as more and more usage shifts to services provided by web sites that are accessed through those browsers. Towards this goal we identify three key …

Decentralized information flow control on a cluster
Information flow control security models can prevent programs from divulging sensitive information in unexpected ways. There has been significant work on tracking information flow between processes in the same computer at the operating system level. I present a modification to the Flume information …

Adaptive chosen all inputs model for analyzing key derivation functions against bit-flip and timing side-channel attacks
… any types of attacks. Nowadays, there are five security models used to analyze the security of KDF proposals. However, none of these security models take into account the KDF analysis against the bit-flipping attack and timing side-channel attack. Therefore, this research proposes a new security …

A Comparison of WAP Development in C# and Java.
… different session management techniques, and security aspects.</p> <p>Generation of dynamic content for WAP devices can be done in a variety of server side languages. C# and Java are two of those languages. Numerical computations and database access performance are important in WAP …

A systems-theoretic security model for large scale, complex systems applied to the US air transportation system
Classical risk-based or game-theoretic security models rely on assumptions from reliability theory and rational expectations economics that are not applicable to security threats. Additionally, these models suffer from serious deficiencies when they are applied to software-intensive, …

The Structure of Secure Multi-Party Computation
… task. Depending on the precise model of security, different sets of tasks admit secure protocols. We take a complexity-theoretic approach to studying the inherent difficulty of securely realizing tasks in various standard security models. * We give the first alternate characterization of …

Blockchain-Based Zero Trust Threat Detection Framework for the Finance Industry Network
… of cyber threats has made perimeter-based security models inadequate, especially in the financial sector, where data integrity, confidentiality, and regulatory compliance are critical. Despite advances, existing frameworks like Zero Trust still face challenges such as centralised trust …

Culturally aligned security in banking. A system for rural banking in Ghana.
… fraud control. It presents a robust information security and internal control model to deal with fraud for the banking system. The rural banking industry has been noted for poor internal control leading to fraud. This has resulted in poor performance and even the collapse of some banks. The Focus …

CYBER SECURITY @ HOME: The Effect of Home User Perceptions of Personal Security Performance on Household IoT Security Intentions
… potential human factors predictors of home user security intentions through the lens of past performance, perceived self-efficacy, and locus of control. While perceived self-efficacy and locus of control are elements in several organizational and individual security models, past performance has …

Adversary-driven state-based system security evaluation
… informed trade-off decisions. In system-level security decisions, quantitative security metrics allow decision-makers to compare the relative security of different system configurations. To produce model-based quantitative security metrics, we have formally defined and implemented the ADversary …

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 …

A generalized adversary decision algorithm and analytic solution methods for advise models
Quantitative security metrics are becoming increasingly important to system administrators. ADVISE generates quantitative security metrics by combining a system vulnerability graph with an adversary profile through an adversary decision algorithm. Previously, the decision algorithm placed …

Hardware security design from circuits to systems
The security of hardware implementations is of considerable importance, as even the most secure and carefully analyzed algorithms and protocols can be vulnerable in their hardware realization. For instance, numerous successful attacks have been presented against the Advanced Encryption Standard, …
