Knowledge Reuse as a Foundation for Security Metrics
The recurring question within the cybersecurity landscape is---why do systems keep getting successfully attacked? This relative ease of system breaches necessitates a reevaluation of what it means for attacks to be ``hard''. Existing security metrics quantify narrow aspects of attack difficulty but …

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 …

A new model for worm detection and response. Development and evaluation of a new model based on knowledge discovery and data mining techniques to detect and respond to worm infection by integrating incident response, security metrics and apoptosis.
… immunology system has been mapped in terms of a security perspective. Furthermore, the encouraging results achieved by this research are validated by applying the security metrics for assigning the weight and severity values to trigger the apoptosis. In order to optimise the performance result, …

A Quantitative Security Assessment of Modern Cyber Attacks. A Framework for Quantifying Enterprise Security Risk Level Through System's Vulnerability Analysis by Detecting Known and Unknown Threats
Cisco 2014 Annual Security Report clearly outlines the evolution of the threat landscape and the increase of the number of attacks. The UK government in 2012 recognised the cyber threat as Tier-1 threat since about 50 government departments have been either subjected to an attack or a direct threat …

Adversary-driven state-based system security evaluation
Quantitative metrics can aid decision-makers in making 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 …

Optimizing clinical trials with Open Trial Chain
… for clinical trial data built for analytics, security, and incentivized sharing through technologies like federated learning and blockchain. With motivated examples derived from real-world reported problems in healthcare, we also demonstrate speed, accuracy, and security metrics. In the …

Bucketization Techniques for Encrypted Databases: Quantifying the Impact of Query Distributions
… remote untrusted servers without compromising security. Bucketization is a privacy preserving technique for executing SQL queries over encrypted data on a DAS server. Bucketization partitions encrypted attributes into queryable tables (buckets), thereby disguising which records are requested. …

Trust Management in the Internet of Things
… of applications while introducing significant security and privacy challenges. Due to the dynamic, heterogeneous, and resource-constrained nature of IoT devices, traditional security solutions are often unsuitable. Trust Management Schemes (TMSs) have emerged as viable alternatives; however, …

Quantitative Metrics and Measurement Methodologies for System Security Assurance
… approaches for preventing attacks through security measurements are crucial for preventing sophisticated attacks. However, proactive measures must employ qualitative security metrics and systemic measurement methodologies to assess security guarantees, as some metrics (e.g., entropy) used …

A systems perspective on cybersecurity in the cloud : frameworks, metrics and migration strategy
… to massive adoption of cloud and among them security remains one of the principal concerns. Traditional failure analysis and prevention frameworks fall exceedingly short to address cybersecurity as is evident by every increasing cybersecurity breaches. New frameworks for cybersecurity are …

Securing Wireless Broadcast Communications against Internal Attacks
… is contingent upon the network's reliability and security. As this wireless revolution continues to unfold, users have grown increasingly concerned with the amount of sensitive information that leaks to unauthorized parties. They have also become more skeptical to the abilities of current …

Modelling and Evaluation of Performance, Security and Database Management Trade-offs in Cloud Computing Platforms. An investigation into quantitative modelling and simulation analysis of ‘optimal’ performance, security and database management trade-offs in Cloud Computing Platforms (CCPs), based on Stochastic Activity Networks (SANs) and a three-tier combined metrics
… for the quantitative analysis of performance, security and database management within a network system (e.g. a cloud computing platform) is presented within this research. Our study provides a methodology for modelling and quantitatively generating significant metrics needed in the evaluation …

Blockchain and Distributed Consensus: From Security Analysis to Novel Applications
… transparency, and consensus-driven security promised by blockchain are unprecedented and can potentially enable a wide range of new applications that prevail in the decentralized zero-trust model. While blockchain represents a secure-by-design approach to building zero-trust …

Performance and Security Trade-offs in High-Speed Networks. An investigation into the performance and security modelling and evaluation of high-speed networks based on the quantitative analysis and experimentation of queueing networks and generalised stochastic Petri nets.
Most used security mechanisms in high-speed networks have been adopted without adequate quantification of their impact on performance degradation. Appropriate quantitative network models may be employed for the evaluation and prediction of ¿optimal¿ performance vs. security trade-offs. Several …

Toward a Decision Support System for Measuring and Managing Cybersecurity Risk in Supply Chains
… confusion about the effectiveness of information security programs concerns not only how to measure, but also what to measure — an issue of equivocality. Thus, to lower uncertainty for improved decision-making, it is first essential to reduce equivocality by defining, expanding, and clarifying …
