Security Configuration Considerations on the FICO Analytic Cloud

Xpress Executor operates in a secure configuration when deployed on the FICO Analytic Cloud. This secure configuration enforces a number of restrictions:

• Solver algorithms are limited to 4 threads.
• Module parameters can only be set in the model itself.
• mmjobs: routines 'connect' and 'detach' are disabled.
• mmhttp: routines httpget, put, post, get and startsrv are disabled.
• mmodbc: connection strings must be of the form "DSN=<dsn>" or use the integrated 'sqlite' driver.

Note These restrictions are in addition to the default rules:

• NoExec (no system calls or interaction with external native code)
• NoReadNoWriteWDOnly (file system access restricted to the current working directory only)
