Abstract: The negative effects of Botnet on the cyberspace cannot be overemphasized. A Botnet is a group of compromised computer systems that are connected to a central controller called a Botmaster. The Botmaster uses command and control (C&C) channels to manipulate Botnets. Devices which are connected to the internet are prone to getting infected by
Abstract: WSNs is a collection of sensor nodes with the capacity of recognizing, physical changes from the environment such as pressure, wind, air pollution, temperature, humidity, forest fire detection, vibration and many others wirelessly among themselves. Coverage of a sensor node is one of the factors that affect the strength and reliability of wireless sensor
Abstract: Sensor nodes are deployed in oreder to observe the surrounding environment for some phenomena of interest in wireless sensor networks. The problem with observing such environments is covering entire area which reflects how well a region is monitored. The random distribution of sensor nodes caused by none-uniform deployment leads to coverage holes in the
Abstract: Multifactor authentication (MFA) uses two or more forms of authentication to permit computer users to access an application using the electronic authentication method after successfully providing two or more factors. Since hackers may quickly guess usernam es and passwords using tools, the traditional log in techniques (username and password) are not totally secure against
ABSTRACT: Wearable and mobile sensors are embedded in smartphones, smartwatches, and other wearable devices to capture human physiological signals to monitor daily activities and health indicators. Some of these sensors include an accelerometer, temperature, electrocardiogram, pulse-oximeter, gyroscopes pedometer, etc. The outlined sensors and many others embedded in wearable and mobile phones have been used for
ABSTRACT: The widespread usage of smartphones has risen significantly, creating new avenues for the production and distribution of both personal and business data. Android and iOS are the two most widely used platforms among the numerous smartphone operating systems. Globally, there are 1.4 billion Android users and 1.0 billion iOS users. Android users outweigh iOS
ABSTRACT: The growth of the Internet and computer network security have aroused users’ responsiveness to the secured network environment as this created a basis for the rapid and comprehensive progress observed in Internet patronage. Part of the challenges in the rapid internet growth is the internet security. Using phishing as an example in today’s world
ABSTRACT: The significance of offshore petroleum in providing the world’s energy demands cannot be over overstated. The growing global energy resources demand, along with considerable technological developments, has resulted in a dramatic transfer of petroleum operations from onshore to offshore locations. States and oil companies are looking to the sea for offshore petroleum resources more
ABSTRACT: In this study, a blockchain technology framework that can handle the drug distribution chain was discussed. Since blockchain technology offers immutability, transparency and tamper-proof, its functionalities are what intrigued the study as it can monitor the movement of drugs in the distribution chain. Counterfeit drugs are a problem in both developed and developing countries.
Abstract A profound consequence of the benefits of the web as a communication platform, and the cloud as a storage medium, is ensuring the security of information in transit and in storage due to its nebulousness. The computational overhead and known attacks associated with the traditional cryptographic methods necessitate a shift in paradigm in order
