Summary:The invention relates to a security interface for a data path. Said security interface comprises a data port (DP1) for connection to a first data processing system (RS1) to be protected and a second data port (DP2) for connection to a second data processing system (RS2). A first computer module (RM1) is connected to the first data port (DP1); a second computer module (RM2) is connected to the second data port (DP2). A first switching element (SE1) is arranged in an internal data path (12) between the first (RM1) and the second computer module (RM2) for opening and closing said internal data path (12). A second switching element (SE2) is arranged between the second computer module (RM2) and the second data port (DP2) for opening and closing the data path (14) between the second computer module (RM2) and the second data port (DP2). A control component (CC) controls the two switching elements (SE1, SE2) in such a manner that at least one of the two switching elements (SE1, SE2) is open.
