# Cyber-Storms Come from Clouds: Security of Cloud Computing in the IoT Era

## TL;DR

This paper surveys the security challenges of integrating Cloud computing with IoT, highlighting that securing IoT devices alone is insufficient due to vulnerabilities originating from Cloud services.

## Contribution

It provides an up-to-date, structured survey of security issues specific to Cloud computing within the IoT era, emphasizing the interconnected risks.

## Key findings

- Security issues are prevalent in Cloud-IoT integration
- Vulnerabilities in Cloud services can lead to widespread cyber-attacks
- Securing IoT devices alone is not enough to prevent cyber-storms

## Abstract

The Internet of Things (IoT) is rapidly changing our society to a world where every "thing" is connected to the Internet, making computing pervasive like never before. This tsunami of connectivity and data collection relies more and more on the Cloud, where data analytics and intelligence actually reside. Cloud computing has indeed revolutionized the way computational resources and services can be used and accessed, implementing the concept of utility computing whose advantages are undeniable for every business. However, despite the benefits in terms of flexibility, economic savings, and support of new services, its widespread adoption is hindered by the security issues arising with its usage. From a security perspective, the technological revolution introduced by IoT and Cloud computing can represent a disaster, as each object might become inherently remotely hackable and, as a consequence, controllable by malicious actors. While the literature mostly focuses on security of IoT and Cloud computing as separate entities, in this article we provide an up-to-date and well-structured survey of the security issues of Cloud computing in the IoT era. We give a clear picture of where security issues occur and what their potential impact is. As a result, we claim that it is not enough to secure IoT devices, as cyber-storms come from Clouds.
