How to make an inventory of information assets within your company? To adapt to ISO 27001

Information assets are the resources that companies use to expedite their management, both hardware and software that respond to an Information Security Management System (ISMS) so that companies function properly and achieve the objectives that have been achieved. proposed.

The assets are associated, directly or indirectly, with all departments of the company.

A security project aims to control the security of the information assets that generate the domain in the study of projects. The limit of the set of assets of the domain does not preclude the consideration of the security relations of said information assets with the environment.

One of the first steps that the company must follow to adapt to ISO 27001 is to carry out an inventory of information assets. They will have the information assets that represent some value for the company and that are within the scope of the ISMS.

You must start by classifying them in some way to make management more agile. There are many ways to do it as explained in our article Classification of IT assets and the reasons for sanitizing the data where each type of asset is shown and this classification can be implemented by companies of different nature.

It is necessary to update the processes of the classification of assets as part of the continuous improvement of the companies since the information assets are very changing in the course of operation of the company. This means that every day, week, months, even years, assets change in each department of the company.

The review of the Information Security Management System should be included when making our inventory.
