  The Internet of Things (IoT) has seen remarkable advancements in recent
years, leading to a paradigm shift in the digital landscape. However, these
technological strides have also brought new challenges, particularly in terms
of cybersecurity. IoT devices are inherently connected to the internet, which
makes them more vulnerable to attack. In addition, IoT services often handle
sensitive user data, which could be misused by malicious actors or unauthorized
service providers. As more mainstream service providers emerge without uniform
regulations, these security risks are expected to escalate exponentially. The
task of maintaining the security of IoT devices while they interact with cloud
services is also challenging. Newer IoT services, especially those developed
and deployed via Platform-as-a-Service (PaaS) and Infrastructure-as-a-Service
(IaaS) models, pose additional security threats. Although IoT devices are
becoming more affordable and ubiquitous, their growing complexity could expose
users to heightened security and privacy risks. This paper highlights these
pressing security concerns associated with the widespread adoption of IoT
devices and services. We propose potential solutions to bridge the existing
security gaps and expect future challenges. Our approach entails a
comprehensive exploration of the key security challenges that IoT services are
currently facing. We also suggest proactive strategies to mitigate these risks,
strengthening the overall security of IoT devices and services.
