abstract = {The a posteriori access control mode consists in monitoring actions performed by users, to detect possible violations of the security policy and to apply sanctions or reparations. In general, logs are among the first data sources that information security specialists consult for forensics when they suspect that something went wrong. One difficult challenge we face when analyzing logs, is the multiple log file formats. However, normalizing logs in one format needs a lot of processing especially because log files usually contain a high volume of data. Our study proposes then to tackle this problem, by leaving the different log formats as they are, and retrieving information from logs by querying them. A semantic mediator makes it possible to inter-operate various sources of information without modifying their internal functioning. It can be responsible for locating data sources, to transmit queries to each source, or from one source to another, to retrieve the queries responses and possibly send them back to other sources. To the best of our knowledge, semantic mediation techniques have been used to share information from heterogeneous data sources, but they were never used in the context of log analysis.},

In this paper, we explore the possibility of extending the total allocated privacy budget, taking into consideration the data consumer characteristics and the data utilisation context. To this end, we first study the problem of privacy budget distribution in adaptive multi-data consumer differential privacy use cases. Then, we present an extension of the classic differential privacy formal model that allows taking into consideration data consumers' information disclosure risk when distributing the privacy budget among them. Finally, we define a method that allows to optimally distribute a given privacy budget among a private database's data consumers.},

abstract = {The Internet of Things (IoT) pervades our surroundings. It softwarizes our physical environments. Software controls devices that interface their physical environments. The IoT is often privacy, safety, and security critical. Consequently, it requires adequate mechanisms for securing its services. For reasons such as heterogeneity, complexity, and lack of deployment there is little research on IoT service security.Our work creates a base for IoT service security. We give IoT services secure identities and attributes. Using site-local X.509v3 certificates with short lifetimes, we show how service attributes can securely be changed at runtime. This enables enforcing security policies even on distributed, loosely coupled IoT nodes. Our central mechanisms are pinning certificates to service executables, and autonomously managing the short certificate lifetimes. We assess the resulting renewal traffic and power consumption. textcopyright 2019 IFIP.},

abstract = {The heart of the Internet of Things (IoT) is data. IoT services processes data from sensors that interface their physical surroundings, and from other software such as Internet weather databases. They produce data to control physical environments via actuators, and offer data to other services. More recently, service-centric designs for managing the IoT have been proposed. Data-centric or name-based communica- tion architectures complement these developments very well. Especially for edge-based or site-local installations, data-centric Internet architectures can be implemented already today, as they do not require any changes at the core. We present the Virtual State Layer (VSL), a site-local data- centric architecture for the IoT. Special features of our solution are full separation of logic and data in IoT services, offering the data-centric VSL interface directly to developers, which significantly reduces the overall system complexity, explicit data modeling, a semantically-rich data item lookup, stream connec- tions between services, and security-by-design. We evaluate our solution regarding usability, performance, scalability, resilience, energy efficiency, and security.},

abstract = {Using a secret password or a PIN (Personal Identification Number) code is a common way to authenticate a user. Unfortunately this protection does not resist an attacker that can eavesdrop on the user (shoulder surfing attack). The Human Semantic Authentication (HSA) protocol proposes a solution against this attack. The main idea is to have concept passwords and to propose images that the user must correctly select in order to authenticate. A concept can be represented by different pictures, so one observation is not enough to retrieve the secret. In this paper, the security/efficiency trade-off in the HSA protocol is evaluated. A probabilistic approach is used. Under the assumption that the picture/concept database is known to the attacker, we show that HSA is barely more resistant to shoulder surfing attacks than a PIN code. More precisely we show that the probability to retrieve the secret concept password increases rapidly with the number of observations. Moreover the constraints on the size of the picture/concept database are very difficult to satisfy in practice.},
