Eliminating vulnerabilities from low-level code is vital for securing software. Static analysis is a promising approach for discovering vulnerabilities since it can provide developers early feedback on the code they write. But, it presents multiple challenges not the least of which is understanding what makes a bug exploitable and conveying this information to the developer. In this paper, we p...

In the last few years, the popularity of web-based applications has grown tremendously. A number of factors have led an increasing number of organizations and individuals to rely on web-based applications to provide access to a variety of services. Today, web-based applications are routinely used in securitycritical environments, such as medical, financial, and military systems. Web-based syste...

Disruptions in the transport system can have severe impacts for affected individuals, businesses and the society as a whole. In this research, vulnerability is seen as the risk of unplanned system disruptions, with a focus on large, rare events. Vulnerability analysis aims to provide decision support regarding preventive and restorative actions, ideally as an integrated part of the planning pro...

Vulnerability to malicious fault attacks is an emerging concern for hardware circuits that process sensitive data. We describe a new methodology to assess the vulnerability to such attacks, taking into account built-in protection mechanisms. Our method is based on accurate modeling of fault effects and their detection status expressed as Boolean satisfiability (SAT) formulae. Vulnerability is q...

Holmgren, Å. J. 2006.Quantitative vulnerability analysis of electric power networks. Division of Safety Research, Department of Transport and Economics, KTH, Stockholm ISBN 10: 91-85539-01-5. Disturbances in the supply of electric power can have serious implications for everyday life as well as for national (homeland) security. A power outage can be initiated by natural disasters, adverse weath...

IP Multimedia Subsystem (IMS) as the core of Next Generation Network (NGN), its security is vital important. However, IMS is a network with openarchitecture based on IP, which brings a lot of security issues. There has already some research results about IMS security, but systematic and model-based research results are lacked. Based on TVRA method, this paper establishes a comprehensive vulnera...

String manipulation errors in input validation and sanitization code are a common source for security vulnerabilities in web applications. This short survey summarizes the string analysis techniques we developed that can automatically identify and repair such vulnerabilities. Our approach (1) extracts clientand server-side input validation and sanitization functions, (2) models them as determin...
