Preset-security for a terminal is determined by the specification of the
USERID parameter.
When considering the security aspects of transaction routing from a preset-security
terminal, remember that preset-security is an attribute of the terminal rather
than of the user who is performing the transaction routing request.
During transaction routing, CICS® creates a surrogate terminal in the AOR to represent the terminal at
which the transaction routing request was issued. Whether the surrogate terminal
has preset- security or not depends upon a number of factors:
- If a remote terminal definition exists in the AOR for the terminal at
the TOR, and specifies the USERID parameter, the surrogate terminal is preset
with this userid. If the USERID parameter is not coded, the surrogate terminal
does not have preset-security.
- If a remote terminal definition does not exist in the AOR, the preset-security
characteristics of the surrogate terminal are determined from the terminal
definition shipped from the TOR. If the shipped terminal definition has preset
security, the surrogate also has preset security, unless the connection to
the AOR is defined with ATTACHSEC=LOCAL, in which case any preset security
information shipped to the AOR is ignored.
