IT asset inventory is the process of tracking and managing the financial, physical, licensing, and contractual aspects of IT assets throughout their life cycle1. IT assets include hardware, software, and network components that an organization values and uses to achieve its objectives2. A complete and accurate IT asset inventory can help an organization to optimize its IT budget, reduce security risks, ensure compliance, and improve performance3.

One of the best controls to enable an organization to ensure a complete and accurate IT asset inventory is performing network scanning for unknown devices. Network scanning is the process of identifying and collecting information about the devices connected to a network, such as their IP addresses, operating systems, open ports, services, and vulnerabilities4. Network scanning can help an organization to:

Discover and inventory all the IT assets on the network, including those that are unauthorized, unmanaged, or hidden

Detect and remove any rogue or malicious devices that may pose a threat to the network security or performance

Update and verify the asset inventory data regularly and automatically, and alert on any changes or discrepancies

Support the asset lifecycle management and maintenance activities, such as patching, upgrading, or retiring assets5
