Practical Internet of Things Security - Second Edition

Inventory control

Asset management is a crucial enabler of enterprise information security. Keeping track of assets and their states is essential to maintaining a healthy security posture. The relatively low cost of many IoT devices does not mean that they can be swapped out and replaced without adhering to stringent processes. If possible, keep track of all IoT assets in your inventory through an automated inventory management system, and ensure that processes are followed to remove these devices from the inventory following secure disposal. Many SIEM systems maintain device inventory databases; keeping the communication pathways open between system operators and SIEM operators can help ensure consistent inventory management.
