A micro-controller-based technology has been developed for monitoring and controlling the water quality and quantity in dam reservoirs by using various sensors. This system is able to automatically detect and measure the changes in water and turbidity levels of incoming water for hydropower production. In this project, an Arduino UNO microcontrolle...

Network spoofing is becoming a common attack in wireless networks. The trend is going high due to an increase in Internet users. Similarly, there is a rapid growth of numbers in mobile devices in the working environments and on most official occasions. The trends pose a huge threat to users since they become the prime target of attackers. More unfo...

Over the last two decades (2000-2020), the Internet has rapidly evolved, resulting in symmetrical and asymmetrical Internet consumption patterns and billions of users worldwide. With the immense rise of the Internet, attacks and malicious behaviors pose a huge threat to our computing environment. Brute-force attack is among the most prominent and c...

Billions of smartphones, globally, are running out-of-date Operating Systems (OS) which make them vulnerable to cyberattacks. Behaviours of users in updating their OS vary between different geographic locations considering various demographic factors. For instance, developing countries have a very different stance compared to developed ones on how...

Billions of smartphones and their users are vulnerable to various cyber-attacks such as phishing, man-in-the-middle, and malware. Among notable reasons for these vulnerabilities are the lack of cybersecurity knowledge, lack of effective cybersecurity legislation, sociocultural, socioeconomic and mainly outdated (obsolete) software applications such...

Phishing attacks have been persistent for more than two decades despite mitigation efforts from academia and industry. We believe that users fall victim to attacks not only because of lack of knowledge and awareness, but also because they are not attentive enough to security indicators and visual abnormalities on the webpages they visit. This is al...

Application layer Distributed Denial of Service (DDoS) attacks are among the deadliest kinds of attacks that have significant impact on destination servers and networks due to their ability to be launched with minimal computational resources to cause an effect of high magnitude. Commercial and government Web servers have become the primary target o...
