Provided are methods and apparatuses for hardening a communication device, which methods and apparatuses make it possible to identify a use of at least one port, by which port a request is submitted to the communication device by a message, and to output a signal for blocking the at least one port if, after a specifiable time period, either the use of the port in question is detected as low or no use of the port in question is detected. Embodiments can be used to harden communication devices in a production line, in a hospital and/or in a power supply network.

Hardening a communication device

A method for protecting a login process of a user to a service provider against brute force attacks is provided. A financial value is transferred from the user to a token provider for a temporary login token. A login attempt is performed by the user on the service provider, wherein the login attempt requires user specific login data and the temporary login token. If the login on the service provider was successful within a predefined number of login attempts, the financial value is transferred back to the user.
