A systems approach to software security in aviation
… for vital avionics functions yet its security has never been studied in depth. Due to the recent introduction of wireless software loading capabilities and Internet-connected in-flight entertainment systems along with several high-profile information security breaches in other sectors, …

On the Co-Optimisation of Reserve Markets: With application to New Zealand
… Operator who clears the market, subject to security constraints. To ensure these security constraints are satisfied, reserves are procured through a co-optimised reserve market. This reserve market is solved simultaneously with the energy market to determine the least overall cost. This …

MULTI-OBJECTIVE GLOBAL OPTIMISATION FOR THE OPERATIONAL ECONOMICS AND SECURITY OF THE INTERCONNECTED AND LONGITUDINAL SYSTEM
Operation optimisation and security analysis are two important issues in modem power system energy management systems. In the first part of the thesis, an approach for the determination of the most appropriate dispatch solution which best meets the economic, environmental and security objectives in …

Optimal Upfc Control And Operations For Power Systems
… system is constrained by steady-state dynamic security constraints. An iterative solution procedure is proposed for the problem, and the solution gives a slightly conservative estimate of the loadibility limit for the generation and transmission system.

Preventing Unintended Data Access: Information Flow Control in eBPF
… enhance tracing, observability, monitoring, and security within the kernel. However, since the kernel is a critical resource containing sensitive information, eBPF also presents a significant attack surface for malicious actors. One of the challenging-to-detect yet easiest-to-execute attacks is …

Efficient Automated Security Analysis of Complex Authorization Policies
… for today's ubiquitous systems. Sophisticated security requirements need to be ensured by authorization policies for increasingly complex and large applications. As a consequence, designers need to understand such policies and ensure that they meet the desired security constraints while …

Privacy Preserving Enforcement of Sensitive Policies in Outsourced and Distributed Environments
… systems. On the one hand, taking any appropriate security decision requires access to these policies. On the other hand, if such access is allowed in an untrusted environment then confidential information might be leaked by the policies. The key challenge is how to enforce sensitive policies and …

Preventive assessment and enhancement of power system voltage stability: an integrated approach of thermal and voltage security
… and enhancement of voltage stability and security in electric power systems. However, in the course of deriving all the proposed methods we have paid attention to keeping them compatible with the (more traditional) handling of thermal overloads, thereby providing a unified treatment of …

Adaptive Quality of Service and Trust Based Lightweight Secure Routing Algorithm for Dense Wireless Sensor Networks
… make them vulnerable to various types of security attacks. Therefore, security mechanisms are needed to secure the network and protect against various security attacks. Conventional security mechanisms, such as cryptography (encryption/decryption) and authentication based systems, are …

Trust-aware virtual network embedding algorithms for wireless sensor networks
… (QoS), and wireless interference handling constraints. Improving the acceptance rate of VNE is essential because the more the virtual network requests (VNRs) can be mapped onto the substrate network, the more revenue they will generate for the infrastructure provider. However, the shared …

Static Extraction Of Dataflow Communication For Security
<p>The cost of security vulnerabilities in widely-deployed code such as mobile applications is high. As a result, many companies are using Architectural Risk Analysis (ARA) to find security vulnerabilities before releasing their applications. The existing analyses are focused on finding local …

A Framework for Deriving Verification and Validation Strategies to Assess Software Security
… and validation (V&V) strategies to assess the security of a software application by testing it for the presence of vulnerabilities. This framework can be used to assess the security of any software application that executes above the level of the operating system. It affords a novel approach, …
