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.
Systems containing important information should be logged in using a multi-authentication logon, also known as either “two-factor”, “multi-factor” or “dual factor” authentication.
For example, when first logging in with a password, a one-time authentication code can also be sent to the user as a text message. In this case, he has been identified by two factors (knowing the password and owning the phone).
Biometric identifiers (eg fingerprint) and other devices can also be used for two-stage authentication. However, it is worth considering the costs and implications for privacy.
Shared accounts should only be allowed if they are necessary for business or operational reasons and should be separately approved and documented.
If shared accounts are used for admin purposes, passwords must be changed as soon as possible after any user with admin rights leaves their job.
The organization must use digital certificates or other similar arrangements to achieve a strong level of authentication equivalent to multi-step authentication for system identities handling maintenance rights or sensitive information.
