Establish and Maintain Detailed Enterprise Asset Inventory

Organisation must maintain a listing of used data systems and their owners. Owner is responsible for completing the related documentation and possible other security actions directly related to the data system.

Data system documentation must include at least:

• System purpose and linked responsibilities
• System's data location (covered in a separate task)
• System's maintenance and development responsibilities and linked partners (covered in a separate task)
• When necessary system's access roles and authentication methods (covered in a separate task)
• When necessary systems interfaces to other systems (covered in a separate task)

Organisation must maintain a listing of controlled data stores and their owners. Owner is responsible for completing the documentation and other possible security actions directly related to the data store.

Data store documentation must include at least:

• Connected responsibilities
• Data processing purposes (covered in a separate task)
• Data sets included in the data store (covered in a separate task)
• Data disclosures (covered in a separate task)
• When necessary, data stores connections to action processes

The organization shall maintain a list of data sets contained in the data stores it manages.

The documentation shall include at least the following information:

• Data systems and other means used to process the data sets
• Key categories of data in the data set (and whether it contains personal data)
• Data retention period (discussed in more detail in a separate task)
• Information on archiving / disposal of data (discussed in more detail in a separate task)

The organization has developed an asset management strategy that involves comprehensive and regularly updated inventories of all physical, virtual, remote, and cloud-connected assets. The asset management strategy includes external assets, utilizing automated tracking tools to ensure accuracy and compliance with data protection regulations.

Mobile Device Management (MDM) helps secure and manage staff mobile devices, whether they are iPhones, iPads, Android devices, or Windows devices. E.g. a Microsoft 365 subscription includes the basics of mobile device management.

Mobile device management system can be used to e.g. configure device security policies, wipe remotely and get accurate device usage reporting.

Assets to be protected related to information and data processing services should be inventoried. The purpose is to ensure that the cyber security is focused on the necessary information assets.

Inventory can be done directly in the management system, but an organization may have other, well-functioning inventory locations for certain assets (including code repositories, databases, network devices, mobile devices, workstations, servers, or other physical assets).

Describe in this task, which lists outside the management system are related to protection of information assets.

The organization shall list all relevant protected assets to determine ownership and to ensure that security measures cover all necessary items.

A large portion of the protected assets (including data sets, data systems, personnel / units, and partners) are treated through other tasks. In addition, the organization must list other important assets, which may be, depending on the nature of its operations, e.g. hardware (servers, network equipment, workstations, printers) or infrastructure (real estate, power generation, air conditioning). In addition the organization should make sure that relevant external devices are documented.
