• 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 (
https://www.vdi.de/richtlinien
).
PROFINET Security Guideline on information security in industrial automation
The PROFIBUS & PROFINET user organization supports you with building up safety standards in
your company with the PROFINET Security Guideline. You will find these guidelines under

ESD Guidelines
ESD
All electronic devices are equipped with large-scale integrated ICs or components. Due to their
design, these electronic elements are highly sensitive to overvoltage, and thus to any
electrostatic discharge.
The acronym ESD has become the established designation for such electrostatic sensitive
components/devices. This is also the international abbreviation for such devices.
ESD devices are identified by the following symbol:
