gw/sec_info is a SAP Parameter attribute which is used to control External security filename for gateway information. This is available within R/3 SAP systems depending on the version and release level.
Below is the standard documentation available and a few details of the attributes values .
This parameter can be used to protect external programs against being
started. Any unauthorized starting of external programs can be prevented
by maintaining the file secinfo in the data directory of the gateway
instance. The the entries in this file have the following
Syntax
USER=<(><<)>user>, [PWD=<(><<)>pwd>,] [USER-HOST=<(><<)>user_host>,]
... HOST=<(><<)>host>,TP=<(><<)>tp>;
A corresponding line will allow the user <(><<)>user> to start the
program <(><<)>tp> on the host <(><<)>host>.
The level of authorization checking performed can be increased by
specifying PWD and/or USER-HOST.
Examples
USER=mueller, HOST=hw1414, TP=test;
USER=hugo, PWD=pass, USER-HOST=hw1234, HOST=hw1414, TP=prog;
User mueller can run program test on host hw1414.
User hugo can run program prog on host hw1414, as long as s/he logged on
to the gateway from host hw1234 and used the CPIC call CMSCSP to set the
security password to pass.
If the user has used the CMSCSU call to set the security user, this is
also used for checking. '*' can be used as a wildcard for all
parameters. If PWD and/or USER-HOST is/are not specified, value * is
assumed.
Example
All users should be allowed to run program test on host hw1414: USER=*
,HOST=hw1414,TP=test;
The current list of security entries can be viewed with the monitor, and
a refresh can be triggered from the security file.
