The data processing environment is separated from public data networks and other environments with a lower security level in a sufficiently safe manner.
Separation of data systems is one of the most effective factors in protecting confidential information. The goal of separation is to delimit the processing environment of confidential information into a manageable entity, and in particular to be able to limit the processing of confidential information to sufficiently secure environments only. Separation of environments can be implemented, for example, with the help of a firewall solution.
