The security setting for a communication link specifies the minimum required
security for a communication:
• Plain-Non-Trusted
Unencrypted telegrams from a potentially unsafe source are accepted
and routed – as long as the checkbox "Disable non trusted routing" is not
checked.
• Plain-Trusted
Unencrypted telegrams from a network physically secured against external
access are accepted and routed.
• Signed-Trusted
Signed telegrams are accepted. Non-signed or incorrectly signed
telegrams are rejected without an error message.
• Encrypted-Trusted
Only encrypted telegrams are accepted. All other telegrams are either
discarded or acknowledged with a fault message as applicable. A
prerequisite for this is the "do not hide" option.
