The topic of data security and access protection has become increasingly important in the
industrial environment. The increased networking of entire industrial systems to the net-
work levels within the company together with the functions of remote maintenance have
all served to increase vulnerability. Hazards can arise from:
n
Internal manipulation such as technical errors, operating and program errors and
deliberate program or data manipulation.
n
External manipulation such as software viruses, worms and Trojans.
n
Human carelessness such as password phishing.
The most important precautions to prevent manipulation and loss of data security in the
industrial environment are:
n
Encrypting the data traffic by means of certificates.
n
Filtering and inspection of the traffic by means of VPN - "Virtual Private Networks".
n
Identification of the user by "Authentication" via save channels.
Segmenting in protected automation cells, so that only devices in the same group can
n
exchange data.
n
Deactivation of unnecessary hardware and software.
