HALE-IoT: HArdening LEgacy Internet-of-Things devices by retrofitting defensive firmware modifications and implants
2022
Internet-Of-Things (IoT) devices and their firmware are notorious for their lifelong vulnerabilities. As device infection increases, vendors also fail to release patches at a competitive pace. Despite security in IoT being an active area of research, prior work has mainly focused on vulnerability detection and exploitation, threat modelling, and protocol security. However, these methods are ineffective in preventing attacks against legacy and End-Of-Life devices that are already vulnerable. Current research mainly focuses on implementing and demonstrating the potential of malicious modifications. Hardening emerges as an effective solution to provide IoT devices with an additional layer of d…
Beyond economic and financial analyses : A revelatory study of IT security investment decision-making process
2022
Information Technology (IT) security breaches and the extent of damage they may cause to an organization are inherently uncertain. Therefore, managers’ decisions about whether to make IT security investment (ITSI) and how much, depend upon a subjective assessment of the economic value of the investment and the likelihood of the damage to the organization. When managers delay or fail to decide on whether and how much to invest in IT security, it can make organizations vulnerable to operational and strategic perils. Based upon interviews, document reviews, and observations in three organizations in Finland that made ITSI decisions to acquire a secure email application system, we examined the …
