This paper presents Kinesis, a security incident response and prevention system for wireless sensor networks, designed to keep the network functional despite anomalies or attacks and to recover from attacks without significant interruption. Due to the deployment of sensor networks in various critical infrastructures, the applications often impose stringent(More)
Packet losses in a wireless sensor network represent an indicator of possible attacks to the network. Detecting and reacting to such losses is thus an important component of any comprehensive security solution. However, in order to quickly and automatically react to such a loss, it is important to determine the actual cause of the loss. In a wireless sensor(More)
Because privacy today is a major concern for mobile applications, network anonymizers are widely available on smartphones, such as Android. However despite the use of such anonymizers, in many cases applications are still able to identify the user and the device by different means than the IP address. The reason is that very often applications require(More)
In a wireless sensor networks, packet losses can result from attacks affecting the nodes or the wireless links connecting the nodes. Failure to identify the actual attack can undermine the efficacy of the attack responses. We thus need approaches to correctly identify the cause of packet losses. In this poster paper, we address this problem by proposing and(More)
In many Internet of Thing (IoT) application domains security is a critical requirement, because malicious parties can undermine the effectiveness of IoT-based systems by compromising single components and/or communication channels. Thus, a security infrastructure is needed to ensure the proper functioning of such systems even under attack. In this paper, we(More)
In wireless sensor networks, packet losses are often an indicator of possible undergoing attacks. Therefore, security solutions aiming at providing comprehensive protection must include functions for packet-loss detection. Determining the actual cause of these losses is crucial to a quick and automated reaction to the attack, be it a simple reporting of the(More)
As privacy today is a major concern for mobile systems, network anonymizers are widely available on smartphones systems, such as Android. However, in many cases applications are still able to identify the user and the device by means different from the IP address. In this demo we show two solutions that address this problem by providing application-level(More)
In this paper, we present an architecture and implementation of a secure, automated, proximity-based access control that we refer to as Context-Aware System to Secure Enterprise Content (CASSEC). Using the pervasive WiFi and Bluetooth wireless devices as components in our underlying positioning infrastructure, CASSEC addresses two proximity-based scenarios(More)
