2026-02-09T05:29:05+00:00

The Internet of Things (IoT) has been instrumental in infusing cross-domain connectivity among devices for the very purpose of making better automation and decisions on data input. However, with its infrequent deployment, a lot of security challenges arise that may hamper system dependability and user trust. This paper considers critical sets of security requisites that are mandatory towards making a strong, dependable IoT system. By conducting a systematic literature review, it identifies key security issues, including data confidentiality, data integrity, authentication, access control, and privacy. Furthermore, possible threats and attacks found in IoT environments are analysed and classified across communication channels, devices and services, users, mobility, and resource integration. Based on the analysis, the key security requirements are then suggested, and these mitigations of vulnerabilities will lead to the secure design of an IoT architecture. The work considers solutions starting from device-level security to secure communication, stronger authentication, and privacy measures. Putting into practice all of these security requirements will improve resilience against attacks, reduce possible threats posed by malicious/unauthorised access, and ensure reliable operation of the system. This work stresses the importance of considering security early in the designing phase of IoT systems for their dependable and secure deployment into various applications such as smart homes, healthcare, industrial automation, and smart cities. Taking measures to address these challenges will, in turn, result in IoT systems possessing enhanced reliability, data integrity, and user confidence in the increasingly interwoven digital environment.
