The most important precautions against manipulation and loss of data security in an
industrial environment are:
● Filtering and verification of data traffic through virtual private networks (VPN). A virtual
private network is used to exchange private data in a public network (e.g. the Internet).
The most common VPN technology is IPsec. IPsec is a collection of protocols based on
the IP protocol at the network layer.
● Segmentation into protected automation cells. The aim of this concept is to protect
devices in the network through security modules. A group of protected devices forms a
protected automation cell. Only security modules in the same group or the device
protected by you can be interchanged.
● Authentication (identification) of the networked devices. The security modules identify
themselves to each other via a secure (encrypted) channel using authentication
procedures. This prevents access to a protected segment by unauthorized persons from
outside.
● Encryption of the data traffic. The confidentiality of the data is ensured by encrypting the
data traffic. For this purpose, every security module is given a VPN certificate which
includes the encryption key.
VDI guidelines on information security in industrial automation
The VDI/VDE Association of German Engineers "Measurement and Automation" has
published a guideline for implementation of a security architecture in the industrial
environment in the VDI guideline "VDI/VDE 2182 Sheet 1, IT Security for Industrial
Automation - General Model". You will find the guideline under "VDI Standards" on the VDI
home page: VDI guidelines (http://www.vdi.de/43460.0.html)
For environmentally friendly recycling and disposal of your old device, please contact a
company certified for the disposal of electronic waste and dispose of the device in
accordance with the regulations in your country.
