An inactive asset is an internet-facing IT element connected to first-party, active assets but is not currently used. Despite being inactive, these assets are part of the attack surface and can leave the door open to threat actors.
Internet of Things (IoT)
The Internet of Things (IoT) is a network of everyday objects interconnected via the internet to send and receive data. These objects are embedded with software or sensors to collect data and send it to other devices or software systems. IoT devices and systems contribute to the attack surface, and they can contain vulnerabilities that attackers can exploit. IoT is prevalent, and some companies add dozens to thousands of IoT assets to their networks that they may not assess or monitor effectively.
