1. An analysis device comprising:
a hardware processor; and
a communication interface,
wherein the hardware processor is configured to load program code from a memory and to execute the program code,
wherein, when the program code is executed, the hardware processor is configured to:
communicate with at least one node of an infrastructure of a distributed database via the communication interface and obtain an authorization for intrusion detection for a computer system;
carry out the intrusion detection for the computer system following the obtaining of the authorization, wherein the intrusion detection is based on an analysis of log messages of the computer system received from the computer system via the communication interface; and
carry out an application for storing registration information indicative of an identity of the analysis device, in the distributed database, depending on a result value of a smart contract implemented by the at least one node.
