Supervisory Control and Data Acquisition (SCADA) systems face the absence of a protection technique that can beat different types of intrusions and protect the data from disclosure while handling this data using other applications, specifically Intrusion Detection System (IDS). The SCADA system can manage the critical infrastructure of industrial control environments. Protecting sensitive information...
With the ubiquitous computing of providing services and applications at anywhere and anytime, cloud computing is the best option as it offers flexible and pay-per-use based services to its customers. Nevertheless, security and privacy are the main challenges to its success due to its dynamic and distributed architecture, resulting in generating big data that should be carefully analysed for detecting...
Fallback authentication is used to retrieve forgotten passwords. Security questions are one of the main techniques used to conduct fallback authentication. In this paper, we propose a serious game design that uses system-generated security questions with the aim of improving the usability of fallback authentication. For this purpose, we adopted the popular picture-based ‘4 Pics 1 word’ mobile game...
Wireless Sensor Networks (WSNs) have a wide variety military applications including battlefield surveillance, enemy tracking, and target classification. In this paper, we propose a WSN architecture based on a mobile sink. The proposed architecture differentiates the regular data from the critical data, and leverages this difference to reduce the energy consumption in WSNs. We formally modeled the...
Intrusion detection systems are a central component of cyber security architecture, and their accuracy is a critical performance metric for any security deployment. Most of the current performance analysis of intrusion detection systems relies on empirical profiling of a given algorithm or implementation against a benchmark dataset. Whilst effective to a point, this traditional evaluation methodology...
The Extensible Messaging and Presence Protocol (XMPP) is one of the most popular Instant Messaging (IM) protocols which uses a client-server working mode. This protocol uses different connection primitives for both client-to-server (c2s) and server-to-server (s2s) connections. It is actively used in mission-critical operations where the reliability and security of communication systems is always imperative...
