Abstract:
1. A communications system having at least one communications means by means of which the communications system is connectable to at least one further processing unit and/or to a further communications system, having at least one first memory, at least one second memory, at least one third memory, and at least one security apparatus, wherein identical information is stored on the first memory and the second memory and wherein damage to the communications system is determinable with reference to a comparison of information stored on the first memory and on the second memory by the security apparatus, wherein the first memory has a system library in which at least one directory of system interfaces provided by the system library is stored as information, and the second memory has a copy of the system library of the first memory in which at least one directory of the system interfaces provided by the system library is stored as information, wherein damaged system interfaces are recognized by the security apparatus by at least a partial comparison of the first memory with the second memory, wherein each damaged system interface is identified by at least one property of the respective system interface which is independent of the communications system and/or of properties of the communications system, the at least one property of each damaged system interface being stored together in a data structure in the third memory and a checksum being formed by the security apparatus based on the data structure, wherein the security apparatus determines a type of damage of the damaged system interfaces by comparing the checksum with an already known checksum stored in the security apparatus.
