5.17: Authentication information

Requirement description

Organization needs to require a controlled management process for handling authentication information, this includes guiding personnel on secure authentication practices e.g. best practices for password selection. Implementing single sign-on (SSO) or other authentication management tools, such as password vaults, reduces the volume of authentication information users need to safeguard.

Personnel guidelines for safe data system and authentication info usage
1. Task description

The organization should have defined guidelines for the generally acceptable use of data systems and for the management of the necessary credentials.

In addition, the owners of data systems classified as 'High' or 'Critical' priority can define, document, and implement more specific guidelines for the use of that particular data system. These guidelines can describe e.g. security requirements related to the data contained in the system.

Use and evaluation of password management system
1. Task description

The password management system allows the user in a registration situation to decide how complex a password is to be set this time and to remember it on behalf of the user.

When using the password management system, e.g. the following principles:

  • the system will force the use of unique passwords in the future
  • the system warns the user to change old recurring passwords
  • the system forces you to choose passwords that are complex enough, of high quality
  • the system forces the user to change the temporary password the first time they log on
  • the system forces you to change the password that may have been compromised in the data leak
  • the system prevents the same passwords from being reused
  • the system keeps password files separate from other data and strongly encrypted

Defining and documenting accepted authentication methods
1. Task description

The organization has predefined authentication methods that employees should prefer when using data systems.

When using cloud services, the user can often freely decide how he or she authenticates with the service. A single centralized authentication account (such as a Google or Microsoft 365 account) can help close a large number of access rights at once when the main user account that acts as the authentication method is closed.

Managing shared user credential through password management system
1. Task description

One way to manage the risks associated with shared usernames is to manage the shared password and its users directly through a password management system.

In this case, it is possible to act in such a way that, for example, only an individual person actually knows the password and the persons who use it.
