Use multifactor authentication

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.

To protect from e.g brute force attacks the organisation must use at least one of the following practices:

• Account is locked after 10 failed login attempts
• Limit for login attempts in 5 minutes is 10

In addition the following password practices should be in place:

• Minimum length of a password should be at least 8
• Passwords don’t have maximum length
• Password is changed when it’s integrity is suspected or known to be compromised

Multi-factor authentication (MFA) helps protect devices and data. To apply it, users must have more information in the identity management system than just an email address - for example, a phone number or an attached authenticator application (e.g. Microsoft, Google, or LastPass Authenticator).

Multi-factor authentication (MFA) is required for administrators in the organization's key data systems.

For example, when first logging in with a password, a one-time identification 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 ownership of the phone).

Biometric identifiers (e.g. fingerprints) and other devices can also be used for multi-stage authentication. However, it is worth considering the costs and implications for privacy.
