Vulnerability assessment of industrial systems using Shodan

The Internet, and many of the related things, hence the term Internet of Things, IoT, continue to expand and take more roles in human lives. Indeed, this enables us to be connected with our devices and the environment. The Internet also enabled us to be continuously informed about the status of our cars, homes, health, family, friends, etc. However, such exposure or publicity for all those things around us risks them being accessed and used by illegitimate users or intruders. In recent years, Industrial Control Systems (ICSs) have been exposed to the public Internet after being traditionally existed in closed communication systems. As a result, there is a critical need to shed light on network security concerns for these systems' safety. Our study evaluates the different communication protocols used in these systems and assesses and analyzes their security vulnerabilities. The results showed no significant correlation between the number of open ports and total recorded vulnerabilities. Results also showed that specific ports are more vulnerable than the rest due to the nature of their services or applications.

Automated summary

The development of the Internet of Things has allowed better connectivity with devices and environments, but also poses security risks. The network security concerns for Industrial Control Systems have been highlighted, with specific ports identified as more vulnerable to attacks.
