Towards an automated attack tree generator for the IoT
The growing frequency and scale of cyber security attacks is daunting. Notable areas of concern are the Internet of Things (IoT) and Operational Technology (OT) systems; the IoT is becoming intimately integrated into our lives, and the physical repercussions of attacks on OT systems can be …

Securing mobile ad hoc network routing protocols
… renders them vulnerable to numerous types of security attacks. The dynamic feature of ad hoc networks makes enforcement of security becomes an extremely challenging issue. The main problem of many proposed routing protocols for ad hoc networks is that these protocols have critical …

Secure execution environment via program shepherding
… during program execution in order to enforce a security policy. Program shepherding provides three basic techniques as building blocks for security policies. First, program shepherding can restrict execution privileges on the basis of code origins. This distinction can ensure that malicious code …

Software and Hardware Techniques for Masking Security Vulnerabilities
Security problems in computer systems are caused by a variety of design deficiencies, implementation defects and, as this thesis shows, by transient errors. The thesis first studies real world security vulnerabilities via an analysis of available security data and experimentation. Results of the …

Multi-representational security modeling and analysis
Many security attacks arise from unanticipated behaviors that are inadvertently introduced by the system designer at various stages of the development. This thesis proposes a multi-representational approach to security modeling and analysis, where models capturing distinct (but possibly …

Sanitizing private data for repair systems
… restore interconnected system integrity after security attacks with a focus of minimizing the exposure of sensitive data in the repair logs. It builds upon Warp, a repair system for Django web applications which logs all major actions taken by the server from incoming request to outgoing …

Strategic and analytics-driven inspection operations for critical infrastructure resilience
… recent natural disasters and cyber-physical security attacks have demonstrated that the lack of effective failure detection and identification capabilities is one of the main contributors of economic losses and safety risks faced by service utilities. This thesis focuses on both strategic and …

Privacy Attacks and Defenses under Security Threats in Machine Learning
… in the real world, including privacy risks and security concerns. In terms of privacy risks, malicious users can steal the private information of other users or model owners, including recovering training data, inferring membership, and cloning the trained model without authentication. In terms …

A Trivium-Inspired Pseudorandom Number Generator with a Statistical Comparison to the Randomness of SecureRandom and Trivium
… They are specially designed to withstand security attacks. In this thesis, we provide descriptions of two CSPRNGs: Trivium, a hardware-based stream cipher designed for constrained computing environments, and OpenJDK SecureRandom, a traditional CSPRNG recommended for Java programs that …

Automated Derivation of Application-Aware Error and Attack Detectors
… important than other data from a reliability or security point of view (we call this the critical data). Protecting only the critical data provides significant performance improvements while achieving high detection coverage. The technique derives error and attack detectors to detect corruptions …

The Paradox of Social Media Security: A Study of IT Students’ Perceptions versus Behavior on Using Facebook
… sites have become major targets for cyber-security attacks due to their massive user base. Many studies investigated the security vulnerabilities and privacy issues of social networking sites and made recommendations on how to mitigate security risks. Users are an integral part of any …

Secure and dependable cyber-physical system architectures
… Systems (CPS) inevitably introduce more security vulnerabilities. The concern about CPS security is growing especially because a successful attack on safety-critical CPS (e.g., avionics, automobile, smart grid, etc.) can result in the safety of such systems being compromised, leading to …

Formal framework and tools to derive efficient application-level detectors against memory corruption attacks
Memory corruptions are a major part of security attacks observed nowadays. Many protection mechanisms have been proposed to fight against them. These techniques can be broadly classified into two categories: those that focus on preventing vulnerabilities from being exploited (canary value, libsafe) …

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 …

On the detection of privacy and security anomalies
… as employees of an organisation. One of the data security and privacy concerns is of insider threats, where legitimate users of the system abuse the access privileges they hold. Insider threats come in two flavours; one is an insider threat to data security (security attacks), and the other is an …

Security threats to the MAC-layer in wireless networks
Medium access control (MAC) protocol security is important in wireless networks due to the lack of physical access control that normally exists in wired networks in the form of connecting a cable. Most efforts in standards organizations and academic research focus on the requirements of …
