A Review of IoT Security Challenges and Solutions

Users’ Privacy and Security Concerns that Affect IoT Adoption in the Home Domain

“…According to the results, over 60% might refrain from using or purchasing smart products for this reason. This conclusion is supported by both Lu et al (2018), who found that users are highly concerned about privacy and security, and Mehdipour (2020), who stated that more than 70% are concerned about privacy and security in smart homes, which leads to users avoiding the products.…”

“…The system should be constantly monitored so that threats can be detected in all security layers. If a device is attacked, actions should be taken to eliminate the threat and ensure that it does not spread while the system is self-healing (Chang & Hung, 2021;Iqbal et al, 2020;Mehdipour, 2020). Therefore, important general IoT security measures for producers would be to secure the network with regular patching, updates, antivirus, firewalls, and IDS/IPS with real-time and predictive analytics to monitor the system, implement two-factor authentication including biometrics, and secure the apps by integrating security in the design and encrypting the data.…”

“…The rapid development and spread of technology have resulted in an increasing number of threats affecting personal security and privacy, particularly in the smart home domain. In just two years, the number of IoT malware collected by Kaspersky Lab increased from just over 3000 to over 121,000, while only one in ten companies were confident in securing their IoT devices (Mehdipour, 2020). If these threats are not appropriately addressed and serious incidents continue to occur regularly, user trust and IoT adoption will be negatively affected, making security, privacy, and trust, the key limitations of IoT (Popescu et al, 2021).…”
