Keep a register of all your assets

The objective is to have up-to-date knowledge of all IT devices in use. This understanding helps you identify possible attack vectors and essential assets for your organization. In case of an incident, it can help you detect where the problem comes from and potentially which supplier you need to contact.

To achieve this you should keep an inventory of your IT assets, like network devices, internet-connected servers, workstations, mobile devices and end-user devices. This inventory of IT assets allows you to understand the scope of your essential assets, to check your maintenance contracts, to identify those resources that are no longer used, but have not yet been decommissioned and to focus budget on the assets that matter to your organization. For the identification of essential assets, it can be useful to link this IT inventory to key business activities and processes. It’s important to keep this inventory up-to-date.
