Embodiment approach

[0011] According to an advantageous embodiment of the invention, the service technician responsible for the faulty component receives a fault ticket via a first communication path and / or using a first message in the event of a fault, the fault ticket containing at least one statement about the component concerned in the automation environment and then deliver or transmit the one-time password via a second communication route and / or using a second message separate from the first message. Dividing communication paths, such as notifying IP addresses in trouble tickets, sending one-time passwords or initial credentials via SMS, makes it more difficult for potential attackers to gain access to relevant data.

[0012] According to another advantageous embodiment of the invention, the secure initial connection is at least an authenticated connection on the server side, via which the service technician can verify his identity by means of a one-time password.

Abstract

The invention relates to a method for establishing a secure connection from a service technician (06, 07) to a component (02, 03) of an automation environment that can be remotely diagnosed and / or maintained and is experiencing failure. A service certificate is required for establishing the secure connection, wherein first a secure initial connection is established to the automation environment (01) by the service technician (06, 07) by means of a one-time password. Via the initial connection, subsequently a service certificate required for establishing the secure connection to the component (02, 03) of the automation environment (01) experiencing the failure is transmitted from the automation environment (01) to the service technician (06, 07), and finally the secure connection from the service technician (06, 07) to the component (02, 03) experiencing the failure is established by means of the service certificate. The invention further relates to an automation environment (01) that is suitable for carrying out a method of said kind.

Description

technical field [0001] Often several different contractors or companies carry out the installation, especially in automation environments, or the individual components originate from different companies. For example, the first company provides automation terminal equipment, the second company provides network components, and the third company provides office components and equipment. Background technique [0002] In order for a service technician, for example, to be able to access an automation terminal, an access certificate is usually used, for example a service certificate with a corresponding private key, or an identification code with a corresponding password or the like. However, this access mechanism has to be installed or configured in advance on the service technician's computer (for example a laptop). In order to avoid excessive downtime (which is costly and therefore especially disadvantageous in an automated environment), it must be possible to set up these acce...
