What is Shodan?

Shodan is a search engine specifically designed to discover and index devices that are connected to the internet. Unlike traditional search engines that primarily index web pages, Shodan goes beyond by scanning the internet and gathering information about the various Internet of Things (IoT) devices, servers, and other equipment that are accessible online. This includes computers, cameras, routers, and even smart appliances.

The significance of Shodan lies in its ability to provide insights into which devices are vulnerable to exploitation due to weak security configurations or outdated firmware. Users such as cybersecurity professionals, researchers, and even malicious actors utilize Shodan to evaluate the security posture of devices and networks, making awareness of its capabilities crucial for marine safety personnel involved in cybersecurity.

Other options do not accurately describe Shodan; it is not an encryption tool, a type of malware, or a social engineering tactic, as those categories pertain to different aspects of cybersecurity and technology. Understanding what Shodan is and what it does helps marine safety personnel to become more adept at recognizing potential security risks in their operational environment.
