User right management

Authentification and authorization

User authentification

Every user can log in with his e-mail address and a corresponding password. The password is stored as a hash value.

The user password must meet the following criteria for security reasons:

  • Password length between 8 and 18 characters.
  • At least one capital letter.
  • At least one lowercase letter.
  • At least one number.
  • At least one special character.

Resetting the password is only possible by the user himself. After a failed login attempt, you can have your password reset. A link to a password reset in the web GUI will be sent to the user by e-mail.

To prevent brute force attacks, the GUI delays a next login attempt by 5 seconds after each failed login.

The backend side login service is limited to 10 calls per minute and IP address and the response time of the login is artificially increased.

User authorization

The following figure illustrates the structure of authorization management. Currently, roles can be assigned to users. In the future, it is planned to enable the creation of custome roles and assignment of groups.
