This paper considers improving the confidentiality of the next generation of wireless communications by using the watermark-based blind physical layer security (WBPLSec) in Visible Light Communications (VLCs). Since the growth of wireless applications and service, the demand for a secure and fast data transfer connection requires new technology solutions...More>>

Increasing the maturity of SMEs with respect to cybersecurity threats is crucial as they are less prepared and less resilient. They are also increasingly exposed and targeted by malicious actors. Providing support means ensuring an effective ecosystem is available to help companies all along the process. Resources have to be...More>>

Advertisement drives the economy of the mobile app ecosystem. As a key component in the mobile ad business model, mobile ad content has been overlooked by the research community, which poses a number of threats, e.g., propagating malware and undesirable contents. To understand the practice of these devious ad behaviors,...More>>

In recent years, the usage of online banking services has considerably increased. To protect the sensitive resources managed by these services against attackers, banks have started adopting Multi-Factor Authentication (MFA). To date, a variety of MFA solutions have been implemented by banks, leveraging different designs and features and providing a...More>>

Web Application Firewalls (WAFs) are plug-and-play security gateways that promise to enhance the security of a (potentially vulnerable) system with minimal cost and configuration. In recent years, machine learning-based WAFs are catching up with traditional, signature-based ones. They are competitive because they do not require predefined rules; instead, they infer...More>>

Intrusion detection has become a problem of big data, with a semantic gap between vast security data sources and real knowledge about threats. The use of machine learning (ML) algorithms on big data has already been successfully applied in other domains. Hence, this approach is promising for dealing with cyber...More>>

Attackers leverage memory corruption vulnerabil-ities to establish primitives forreadingfrom orwritingto theaddress space of a vulnerable process. These primitives formthe foundation for code-reuse and data-oriented attacks. Whilevarious defenses against the former class of attacks have proveneffective, mitigation of the latter remains an open problem.In this paper, we identify various shortcomings of...More>>

The paper presents OutGene, an approach for streaming detection of malicious activity without previous knowledge about attacks or training data. OutGene uses clustering to aggregate hosts with similar behavior. To assist human analysts on pinpointing malicious clusters, we introduce the notion of genetic zoom, that consists in using a genetic...More>>

The world has seen an influx of connected devices through both smart devices and smart cities, paving the path forward for the Internet of Things (IoT). These emerging intelligent infrastructures and applications based on IoT can be beneficial to users only if essential private and secure features are assured. However,...More>>
