Organizations face the issue of how to best allocate their security resources. Thus, they need an accurate method for assessing how many new vulnerabilities will be reported for the operating systems (OSs) and web browsers they use in a given time period. Our approach consists of clustering vulnerabilities by leveraging the text information within vulnerability records, and then simulating the mean...
Simulation-based fault injection is a well-known technique to assess the dependability of hardware designs specified using hardware description languages (HDL). Although logic faults are usually introduced in models defined at the register transfer level (RTL), most accurate results can be obtained by considering implementation-level ones, which reflect the actual structure and timing of the circuit...
When provided with more powerful or extra hardware, state-of-the-art Byzantine fault-tolerant (BFT) replication protocols are unable to effectively exploit the additional computing resources: on the one hand, in settings with heterogeneous servers existing protocols cannot fully utilize servers with higher performance capabilities. On the other hand, using more servers than the minimum number of replicas...
Security vulnerabilities are a concern in systems and software exposed via networked interfaces. Previous research has shown that only a minority of vulnerabilities can be emulated through software fault injection techniques. This paper aims to accurately emulate software security vulnerabilities. To this end, the paper provides a field-data study on the operators needed to emulate vulnerabilities...
Automated Static Analysis Tool (ASATs) are one of the best ways to search for vulnerabilities in applications, so they are a resource widely used by developers to improve their applications. However, it is well-known that the performance of such tools is limited, and their detection capabilities may not meet the requirements of the project regarding the criticality of the application. Diversity is...
