Abstract
The invention includes a method and a communication network for preventing impermissible access to software applications implemented in field devices, wherein the field devices are integrated in a communication network of automation technology and wherein each software application exchanges information within the communication network via at least one communication interface. The method includes registering currently activated safety functions of each of the communication interfaces; registering all activatable safety functions of each communication interface; ascertaining at least one shared safety function, which is activatable in each of the communication interfaces; displaying the shared safety functions and selecting at least one displayed, shared safety function; and reconfiguring each of the communication interfaces, wherein currently set safety functions are replaced by the at least one selected, shared safety function, and when no shared safety function was ascertained, each of the communication interfaces is so reconfigured that no safety function is activated.
