Abstract: The temperature-sensitive industries including healthcare, agriculture and cold chain logistics the Internet of Things (IoT) has greatly increased monitoring and management of environmental conditions. Minor temperature fluctuations can lead to the deterioration of products, diminished effectiveness of pharmaceuticals, or suboptimal agricultural results. This work presents the design and development of a thermologger system for real-time temperature monitoring and data recording system based on the Internet of Things (IoT). The Internet of Things (IoT) has emerged as a revolutionary solution, facilitating real-time monitoring, sophisticated analysis and automated decision-making across several sectors. The system incorporates low-power digital temperature sensors, a microcontroller unit (MCU) and a wireless communication module based on the ESP-8266. These components work together to collect temperature data and transmit it to a cloud platform for storage and analysis. A key feature of the system is its user-friendly interface, available through a mobile app and a web dashboard. These platforms enable users to view temperature trends, receive alerts when temperatures fall outside of safe ranges and generate reports for further analysis. The alert mechanism is especially useful in high-risk areas such as vaccine storage, greenhouse operations, large industrial cold storage, datacenter and food transportation where timely intervention can prevent significant loss. Real-world testing demonstrates the system’s accuracy, responsiveness, and dependability. These findings validate the system’s efficacy and affordability as a continuous temperature monitoring solution for critical applications. All things considered the proposed thermologger system may enhance operational decision-making, boost safety and optimize resource use across a range of industries.

Abstract: The rapid adoption of Information and Communication Technologies (ICTs) in Kenyan public universities has enhanced administrative efficiency and academic delivery. Still, it has also exposed networks to escalating cyber threats, including intrusions and data breaches. The study reveals challenges faced by institutions of higher learning amid rising threats to their cybersecurity as they advance their information technology infrastructure and expand their reliance on internet-based software to enhance their educational, research, as well as administrative activities. This study conducts an empirical analysis of network vulnerabilities and attack patterns in Kenyan public university networks, leveraging 1,290 Secure Shell (SSH) security event logs from the Kenya Education Network (KENET). Employing a quantitative approach grounded in Design Science Research Methodology (DSRM), we categorize vulnerabilities by severity and Common Vulnerabilities and Exposures (CVEs), revealing that medium-severity attacks dominate (94.4%), with SSH-general (57.3%) and CVE-2023-48795 (37.4%) incidents prevalent, peaking between 01:00–03:00. These findings high- light critical risks, such as protocol downgrade attacks and brute-force attempts, necessitating robust cybersecurity measures. We propose actionable recommendations, including automated vulnerability scanning, real-time monitoring, and multi-factor authentication, to enhance network resilience. This study contributes a context-specific analysis of cybersecurity risks in higher education, addressing a gap in localized threat assessments for developing nations.
