This paper focuses on conducting forensic data analysis of 2 widely used IMs applications on Android phones WhatsApp and Viber. The tests and analysis were performed with the aim of determining what data and information can be found on the devices internal memory for instant messengers eg chat messaging logs and history send & received image or video files etc. The experiments and results show that heavy amount of potential evidences and valuable data can be found on Android phones by forensic investigators
The serious issue in the field of wireless communication is the security and how an organization implements the steps against security breach. The major attack on any organization is Man in the Middle attack which is difficult to manage. This attack leads to number of unauthorized access points, called rogue access points which are not detected easily. In this paper, we proposed a Hopfield Neural Network approach for an automatic detection of these rogue access points in wireless networking. Here, we store the passwords of the authentic devices in the weight matrix format and match the patterns at the time of login. Simulation experiment shows that this method is more secure than the traditional one in WLAN.
In the unprecedented times today, brought about by the outbreak of the COVID-19 pandemic globally, the education sector has been affected, just like the other industries. Many educational institutes have shut down and suspended traditional physical classroom activities. There has been a shift to the online mode of teaching-learning or ‘e-learning’, which is a web-based digital system that incorporates innovative ICT for facilitating interactive and learner-centered learning environment. In this work, the strengths, drawbacks, and opportunities offered by various popular online educational platforms are explored and compared. Furthermore, data is collected from teachers and students across different courses from various colleges in Delhi through surveys, with questions pertaining to their perspectives and experiences with respect to online educational platforms. Their responses were analyzed statistically and based on the analysis, suggestions, and recommendations have been made, which can contribute implementation and growth of e-learning methods in the future.
Abstract-The need for computer software development is fast growing in our society today. The major challenges faced by the industry is to provide products with quality and functionality at low cost and short time. To meet these challenges software development must be coped with complexity and to adapt quickly to changes. The solution of this is reusability. A number of software life cycle models existing today focused on building on traditional software systems. But the question is whether these existing models are ready to fit in this emerging field. Several life cycle models for component based software development have been introduced by researchers. The role of component based software engineering is to develop the reusable components and assemble them into one system. In this research, we surveyed some of the popular approaches and provide a comparative study of these approaches.
