Advantages and Disadvantages of Host-Based Authentication

Advantages

  • Non-interactive login is relatively easy to set up in large networks. Generally no end-user action is needed.

  • Users do not have direct access to the private key.

  • In host-based authentication with certificates, it is possible to further limit user authorization based on host certificate contents.

  • Can be used together with other forms of authentication.

Disadvantages

  • Trust is placed on the administration of the client host. Server relies on the integrity of the user account management on the client host.

  • Should only be used if the client host is administered by the same organization as the server host.
