Abstract

The invention relates to a device (7) for checking at least one firewall device (6) and a method for protecting at least one data receiver (3). In the method according to the invention, in the data exchange (16) in the direction of the data receiver (3), permissible and impermissible data exchanges are distinguished according to predetermined rules, and impermissible data exchanges are blocked and permitted data exchange. In order to check the function of the firewall device ( 6 ), it is provided according to the invention that the permitted data exchange ( 18 ) is interrupted if the permitted data exchange ( 18 ) has impermissible data exchanges.

Description

technical field [0001] The invention relates to a device for checking at least one firewall device, which is designed to distinguish between permitted and impermissible data exchanges in the direction of a data receiver and to block impermissible data exchanges according to predetermined rules, And release allowed data exchange. [0002] Furthermore, the invention relates to a method for checking at least one firewall device, wherein, in data exchanges in the direction of a data receiver, permissible and impermissible data exchanges are distinguished according to predetermined rules, and impermissible ones are blocked. Data exchange, and release allowed data exchange. Background technique [0003] Safety-critical installations, such as signaling networks of railway installations or networks within nuclear power plants, often have special security areas in which direct data access is not possible. Nevertheless, there is an increasing need for remote access to plant elements...
