The rapid burst of Internet usage and the corresponding growth of security risks and online attacks for the everyday user or the enterprise employee have emerged the terms Awareness Creation and Information Security Culture. Nevertheless, security education widely has remained an academic issue. Teaching system or network security on the basis of practical experience inherits a great challenge for the teaching environment, which is traditionally solved using a computer laboratory at a university campus. The Tele-Lab project offers a system for hands-on IT security training within a remote virtual lab environment-over the web, accessible by everyone. Such a system is inherently exposed to various security threats, since it has to provide full access to virtual machines running attack tools for potentially malicious users. The paper at hand introduces usage, management and operation of Tele-Lab as well as its architecture. Furthermore, this work focuses on possible attacks, the challenges when securing such a system, and shows how to set up an infrastructure that ensures the main security objectives identified as authentication, authorisation and availability.

A user has several personal computers, including mobile phones, tablets, and laptops, and needs to watch live camera feeds from and videos stored at any of these computers at one or more of the others. Industry solutions designed for many users, computers, and videos can be complicated and slow to apply. The user must typically rely on a third party service or at least log in. The Personal Video Distribution (pVD) system supports sending and viewing live and stored videos between any of a single user's computers, and allows for a smooth handover of play back between computers. The system avoids any third parties, and relies only on the user's personal computers. We present the architecture, design and implementation of the pVD prototype. The architecture is comprised of functionality for sending videos, subscribing to videos, and maintaining the video play-back state. The design has a local side sending and viewing videos, and a global side coordinating the switching and distribution of videos, and maintaining subscriptions and video state. The prototype is primarily done in Python. A set of experiments was conducted to document the performance of the prototype. The results show that pVD global side has low CPU usage, and supports a handful of simultaneous exchanges of videos on a wireless network.

“…M-learning systems [1] provide support for access to educational content anytime, anywhere and from many devices. Various experiments have demonstrated that an adaptive approach can be effective when rich educational content is delivered to PDAs [2] or iPods [3]. However, how mobile devices can accurately detect the environment conditions (e.g.…”

“…Playing a video that is streamed over the wireless network to a mobile device is an energy intensive task. In this situation, a large quantity of the power drained from the battery is consumed by the WNIC for packets reception and processing (1), by the CPU and memory for decoding and generating the video frames (2), and by the display and speaker(s) for displaying the video (3). (1), (2), and (3) correspond in a good measure to the three stages of multimedia streaming: data reception, decoding and playing respectively.…”

Abstract-People using mobile devices for studying multimedia based educational content are often on the move and thus rely solely on their device battery power supply. When battery power runs low, they have to stop their activities, significantly reducing their learning outcomes and their satisfaction. This paper proposes a solution to perform the personalisation of the multimedia educational content, based both on the learner profile and on the available power resources on the device used. The solution aims to increase the battery life without affecting learner's quality of experience. Experimental results show that the battery life can be increased by changing streaming related parameters while preliminary subjective tests have assessed their impact on end user perceived quality of the multimedia clip.
