NOTICE
Security risk due to data manipulation and data sniffing
Anonymous access can be a security risk. Anonymous access should therefore be strictly
limited to commissioning.
● For normal operation authentication via username and password or based on
certificates should be used (see chapter Certificate handling (Page 22)).
NOTICE
Security risk due to data manipulation and data sniffing
If no message encryption to the client is established, there will be a security risk of data
manipulation and data sniffing. It is therefore highly recommended to establish a message
encryption to the client.
● Use the highest possible encryption standard (256 bit) to ensure a secure message
transfer.
