Authors: Urgen Maharjan, Gakegni Ngaste Aperhy, Sahasra Nagaraj, Sahil Gupta, Prithi M

Abstract: The recent fast digitalization of the educational system has seen the introduction of online examination systems in universities, examining bodies and professional organizations in large numbers. Even though these platforms enhance accessibility, scalability, and operational efficiency, they present vital security and integrity issues that pose a threat t o the credibility of online tests. The significant security issues are impersonation by candidates, contract cheating, leaking of question papers, tampering with answer scripts, unauthorised collusion, malware-based attacks, network breach and massive distributed denial-of-service (DDoS) attacks. Also, the introduction of remote proctoring systems based on AI provokes serious concerns about privacy, ethical and data protection issues. The currently in place security systems like password-authenticated access and crude browser limitation are inadequate in stopping advanced methods of cheating as well as online threats. The modern studies suggest sophisticated measures such as multi-factor authentication, facial recognition-based and key-stroke dynamic-based biometric verification, end- to-end encryption algorithms to ensure safe data delivery, blockchain-based transparent record keeping, behavioral analytics, abnormality detection approaches that use AIs, and lockdown browsers. Nevertheless, such solutions tend to cover single facets of security and can pose issues of computational cost, scalability, implementation cost and user confidentiality. The paper provides the in-depth examination of security issues with online examination systems and reviews the modern research-based solutions in a systematic way. The comparative assessment framework is created to determine the efficiency, practicability and constraints of different security mechanisms. According to the results, a multi-layered security architecture will be introduced incorporating the elements of authentication, communication security, intelligent monitoring, and tamper-resistant data management to guarantee the examination integrity, confidentiality, availability, and accountability. The research concludes that a combination of defense in depth strategy is crucial towards the attainment of secure, scalable and reliable online examination ecosystems.

Abstract: In recent years, the rapid growth of global energy demand, along with the ongoing depletion of traditional fossil fuel resources, has made the need for sustainable, renewable, and decentralized energy solutions more urgent. Traditional energy generation methods are increasingly unable to meet rising consumption while ensuring environmental sustainability. Among the various alternative approaches, capturing human kinetic energy produced during everyday activities has emerged as a promising and eco-friendly solution. Human movement, especially in crowded public areas, is an underused and always available energy source. This paper presents the design and implementation of a footstep-based electricity generation system that uses piezoelectric sensors to convert human movements into usable electrical power. The system works on the principle of the piezoelectric effect, where mechanical pressure from footsteps is turned into electrical energy. The electrical output produced is usually alternating and highly variable. It is processed to ensure stable operation through rectification, filtering, and conditioning with appropriate power electronic circuits. A buck-boost converter regulates the voltage levels effectively and allows for the reliable storage of the collected energy in rechargeable batteries. An Arduino-based microcontroller is included for smart monitoring, which provides real- time readings of voltage levels, footstep counts, and system performance displayed on a 16×2 LCD module. The stored energy is used to power low- power DC devices like LEDs and mobile charging ports, as well as AC loads through an inverter circuit. Experimental tests show that the generated power increases with the load and footstep frequency. This demonstrates the potential for deploying the system in high-footfall public spaces such as railway stations, shopping malls, and smart city infrastructures.

Authors: Arjun Pillai

Abstract: Modern enterprises operate in highly dynamic digital ecosystems where applications must support large volumes of concurrent users, real-time processing, and continuous service availability. To meet these expectations, information systems are required to be scalable, resilient, and economically efficient while maintaining consistent performance across geographically distributed environments. Traditional monolithic architectures are increasingly unable to satisfy these requirements because they rely on tightly coupled components, rigid deployment cycles, and manual infrastructure management. These limitations result in slower innovation, increased downtime risk, and higher operational costs. The emergence of cloud computing combined with automation technologies has significantly transformed enterprise system design. Cloud platforms provide elastic resource provisioning and geographically distributed infrastructure, while automation enables repeatable configuration, rapid deployment, and continuous operational monitoring. Together, they enable organizations to transition from hardware-centric infrastructure management to software-defined operational environments capable of adapting to workload fluctuations in real time. This review examines the architectural evolution of enterprise systems from monolithic models to service-oriented and microservices-based architectures. Particular emphasis is placed on enabling technologies including Infrastructure as Code (IaC), DevOps methodologies, containerization, orchestration frameworks, and artificial intelligence–driven automation. The study also analyzes cloud service and deployment models, monitoring and observability mechanisms, and integrated security automation approaches that enhance reliability, availability, and operational efficiency in distributed enterprise platforms. Furthermore, the review discusses key implementation challenges such as vendor lock-in, data protection requirements, operational complexity, and financial governance associated with automated cloud environments. Emerging trends including autonomous operations, predictive scaling, and self-healing infrastructure are explored to illustrate the future direction of enterprise computing. Overall, the convergence of automation and cloud technologies establishes a foundational paradigm for next-generation enterprise digital infrastructure, enabling adaptive, intelligent, and continuously evolving software systems.

Cloud-Native Enterprise Engineering: Design, Automation, And Operations

Uncategorized

Authors: Tariq Mahmood

Abstract: Cloud-native enterprise engineering has emerged as a transformative paradigm that shifts organizational computing models from rigid monolithic information systems to scalable, distributed, and continuously evolving digital platforms. Traditional enterprise applications were designed for stable infrastructure environments and infrequent updates, whereas modern digital ecosystems require rapid feature delivery, elastic scalability, and uninterrupted service availability. Cloud-native engineering addresses these requirements by designing applications specifically for dynamic cloud environments rather than merely migrating legacy software to virtualized infrastructure. This paradigm integrates several foundational technologies and practices, including microservices-based architectural decomposition, containerization for environment consistency and portability, declarative infrastructure provisioning, and automated delivery pipelines. Together, these enable continuous integration and continuous deployment, allowing organizations to release software updates reliably and frequently. Automation minimizes manual intervention, reduces operational risk, and improves development productivity, thereby aligning software delivery speed with business agility. Beyond development workflows, cloud-native engineering introduces new operational methodologies. Observability practices provide real-time insights into system behavior using metrics, logs, and distributed tracing, enabling proactive issue detection and faster incident resolution. Reliability engineering principles such as service level objectives and error budgets allow organizations to balance innovation velocity with system stability. Additionally, integrated security practices embed vulnerability detection and policy enforcement throughout the software lifecycle, transforming security from a reactive process into a continuous responsibility. The transition to cloud-native engineering also requires significant organizational transformation. Enterprises move from siloed development and operations teams toward cross-functional collaboration supported by internal platforms and self-service infrastructure. While this shift improves efficiency and scalability, it introduces challenges including operational complexity, skill shortages, governance requirements, and financial cost management in dynamically scaling environments. Overall, cloud-native enterprise engineering represents more than a technological evolution; it is a comprehensive operational and cultural shift. By combining architectural modernization, automation, and collaborative practices, organizations can achieve resilient, adaptive, and continuously improving digital systems capable of supporting modern service-driven economies.
