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).

Documentation of assets inventories outside the ISMS

Critical
High

Low

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.

Documentation of personal data outside data systems

Critical
High

Registrants have the same rights to their personal data, no matter in what form we store them. We need to be able to communicate processing and provide data subjects with access to personal data, whether on paper, in local files or in data systems.

We separately document personal data that is stored outside of data systems.
